Some of the problems faced by food products can be solved by choosing the right form of Fish oil addition and process to ensure oxidative stability, flavor, and uniformity of Fish oil distribution in the product. There are usually 3 forms to choose from pure Fish oil, emulsion, and microencapsulation, and I will introduce you to each of these below.
Here is the list of contents：
·Pure Fish oil
·Emulsions
·Micro-encapsulation
The direct addition of pure Fish oil is not very widely used in food and is suitable for some bread, pure oil-based products (such as vegetable oil), and other products that do not require high uniformity of dispersion but have high requirements for raw material quality, oxidative stability, and flavor.
1. The quality of Fish oil raw materials directly determines its value and application. High-quality Fish oil not only requires its physical and chemical indicators such as acidity, color, and peroxide value to meet a specific range but more importantly, the content of contaminants in it is strictly controlled.
2. Fish oils are highly susceptible to oxidation and the challenge is to improve their stability. The common methods to maintain the stability of Fish oil include protection from light, heat, low temperature, vacuum or nitrogen storage, etc. The addition of antioxidants is more effective and can achieve effective chelation of metal ions and scavenging of oxygen radicals.
1. The emulsion form allows Fish oil to be evenly dispersed in aqueous food systems, with oil-in-water Fish oil emulsions being more widely used in food systems than water-in-oil types. Several factors can affect the stability of Fish oil emulsions. For example, the DHA in Fish oil emulsions adopts a highly protective conformation at the interface against oxidative attack by free radicals and metal ions.
2. The emulsification process generally involves a homogenization process, where both homogenization pressure and temperature have an impact on stability. The effect of temperature on the oxidative stability of Fish oil emulsions is more complex. Temperature affects the actual composition of the Fish oil interface and it is generally accepted that higher temperatures will accelerate oxidation, but increasing the homogenization temperature within a certain range can change the protein conformation.
1. Fish oil microcapsules are powdered Fish oil products made from Fish oil as a core material, which is encapsulated by a specific process using wall materials. This allows the Fish oil to be isolated from the external environment, delaying oxidation, disguising the fishy smell, and greatly improving dispersibility, providing easy access and stable quality raw materials for Fish oil food production.
2. The traditional process of preparing Fish oil microcapsules is mainly emulsification and spray drying. In the preparation process, it is necessary to choose the appropriate wall-to-core ratio and concentration, to ensure that the embedding effect of the premise takes into account the economy. It is also important to note that the larger the particle size of some microcapsules, the more air that may be encapsulated and the more unstable they are. As market demand increases, several new Fish oil microcapsule processing technologies are emerging.
From the above, we know that the three forms of Fish oil addition have their suitable applications and advantages and disadvantages, but basically, they can meet the application needs of different food systems and obtain a product with nutritional value and stability.
They can be divided in to desired dosage strength without process or formulation changes.
When pellets containing the active ingredient are in the form of suspension, capsules, or disintegrating tablets, they offer significant therapeutic advantages over single unit dosage forms.
They can also be blended to deliver incompatible bioactive agents.
They can also be used to provide different release profile at the same or different sites in the gastrointestinal tract.
Pellets offer high degree of flexibility in the design and development of oral dosage form like suspension,sachet, tablet and capsule.
Pellets disperse freely in gastro intestinal tract (GIT), maximize drug absorption, and minimize local irritation of the mucosa by certain irritant drugs.
Improved flow characteristics: Spheres have excellent flow properties, which can be used in automated processes or in processes where exact dosing is required, e.g. tableting, moulding operations, capsule filling, and packaging.
Coating: Coating of granules is often applied for stabilizing active ingredients in the granule or to control the release of these active ingredients. Typical applications in the pharmaceutical industry are the controlled release medicines. The easiest shape to coat is the sphere due to the absence of edges. It is also the most economical one to coat as no extra coating material is required to fill irregularities in the surface of the granules.
Packing of beds and columns: In certain processes, porous beds or columns are used as chemical reactors. Spherical particles allow the reproduction of beds withalways the same void volume, surface area and permeability. Calculations and predictions of the process characteristics also become easier when round particles are used as many equations are based on flows around symmetrical bodies.
Density increase: Both the true and the bulk density of granules are increased by spheronising. This can improve the process and the packaging.
Marketing: For consumer products, spheronising is sometimes only applied for improved product appearance and marketing reasons.
Hardness and friability: Hardness and friability depend on the internal cohesive forces and surface characteristics. Spheronization increases the hardness and reduces the friability of granules. This will reduce the amount of fines generated during handling or transportation.
There is no single product category for our health food products in the USA. Most health food products can be classified as Dietary Supplement or general food with functional claims, and all of them fall within the scope of food regulation. Next, let's take a look at the scope of a Dietary Supplement in the United States and the regulatory authorities. Here are some answers.
Here is the content list:
l The scope of Dietary Supplement in the USA.
l Regulatory authority for Dietary Supplement in the United States.
A Dietary Supplement is a product (not tobacco) intended to supplement the diet and may contain one or more of the following dietary ingredients: vitamins, minerals, herbs (herbal) or other plants, amino acids, and dietary ingredients to increase the total daily intake, or a concentrate, metabolite, extract or combination of these ingredients. It may not be consumed in the form of tablets, capsules, powders, soft gels, or oral liquids; it may not be consumed as a conventional food or as the sole component of a meal diet. DSHEA also allows the use of pharmaceutical ingredients, such as approved or licensed new drugs, antibiotics, biologics, etc., provided that they have been marketed as Immunity increases or food before the relevant approval, certification, or licensing; however, if they have not been marketed as a Dietary Supplement or food before the relevant approval or certification, they may not be used as a Dietary Supplement. However, if the substance has not been marketed as a Dietary Supplement or food before the relevant approval or certification, it may not be used in Dietary Supplement.
The US Food and Drug Administration (FDA), one of the federal executive agencies of the Department of Health and Human Services (HHS), is the regulatory authority for Dietary Supplement, which is different from "conventional" foods and drugs, primarily under DSHEA, which was established in 1994. Dietary Supplements and Dietary Ingredients Manufacturers and distributors of dietary supplements and dietary ingredients are responsible for assessing the safety and labeling of their products before marketing to ensure that they meet all the requirements of DSHEA and the relevant FDA regulations. The Centre for Food Safety and Applied Nutrition (CFSAN) is responsible for the safety and labeling of the Hard capsules. The National Institutes of Health (NIH), one of the HHS divisions, focuses on scientific research and the NIH Office of Dietary Supplement (ODS) coordinates the overall management of the Dietary Supplement. The common goal of NIH and FDA is to promote public health by facilitating the translation of basic and clinical research into medical products and treatments. These agencies complement each other in their roles and functions: NIH supports and conducts biomedical and behavioral research, and FDA ensures the safety and efficacy of medical and other products. In addition, the Committee on Dietary Supplement Labelling (CDSL) examines the regulatory and Dietary Supplement claims on labels and provides recommendations on how best to provide consumers with information that is truthful, scientifically valid, and not misleading. The Commission is composed of seven members appointed by the President. The members of the committee should have expertise and experience in the manufacture, regulation, distribution, and use of Dietary Supplement. At least three of the members should have scientific training and experience to assess the health benefits of Dietary Supplement use, and one of the members should have experience in pharmacology, medical botany, traditional herbal medicine, or other science-related fields. Committee members and staff should be free from bias on Dietary Supplement issues.

Dietary Supplement contains only dietary ingredients that are present in the food supply. And the food has not been chemically altered. Chemical alterations are changes in the molecular structure or composition of the ingredients through hydrolysis, distillation, altered production, or fermentation conditions. For example, the use of media containing high levels of sodium selenite can germinate garlic and fermented yeast can produce high levels of organoselenium compounds. Next, we take a look at the summary of the use of Dietary Supplement and their safety profile. Here are some answers.
Here is the content list:
l Summary of the use of Dietary Supplement.
l Demonstrate the safety of Dietary Supplements, otherwise, they will be considered adulterated products.
To a certain extent, the use of Health food has become increasingly common and has influenced the nutritional status of populations. Therefore, the interference of Dietary Supplements should be taken into account when conducting studies on the health effects of nutrients, the efficacy of drugs, and other health-related studies. The possible confounding effects of other user-related behaviors should also be taken into account when evaluating the effects of Dietary Supplements used. In the absence of data on Dietary Supplement use in developed countries, work should be carried out as soon as possible to identify the problem and consider the influencing factors to develop appropriate intervention strategies in China. In addition, the investigation of Dietary Supplements should pay attention to the unification of concepts and methods to facilitate comparison between studies so as to obtain the maximum value of research.
Those who manufacture or distribute the dietary ingredient or Dietary Supplement should provide the Secretary with information that supports their conclusion that the Dietary Supplement containing the dietary ingredient is reasonably expected to be safe, including any references to published research. In other words, if a dietary ingredient intended for use in a Dietary Supplement is not present in the same chemical form in the food supply, an explanation must be given as to why the new dietary ingredient is considered safe for use under the conditions recommended or suggested by the label. If it is uncertain whether a dietary ingredient is a "new dietary ingredient", a notification may still be submitted. Regardless of whether a premarket notification is required, manufacturers and distributors are responsible for assessing the safety of the dietary ingredient used and must ensure that Vitamins sold or distributed are not adulterated. Sales records, sales contracts, manufacturing records, commercial invoices, magazine advertisements, or sales brochures can all be used as evidence to determine whether a dietary ingredient is new.

Sulfur is essential, but for humans, it is not recommended for intake. Instead, recommended intakes have been established for the sulfur-containing amino acids methionine and cysteine. There are Dietary Supplements that provide sulfur, such as taurine. Next, let's take a look at the types of Dietary Supplements available. Here are some answers.
Here is the content list:
l Minerals
l Protein and amino acids
Although, in general, Dietary Supplements are not allowed to be labeled and marketed with claims of disease prevention or treatment, the US Food and Drug Administration (FDA) has conducted a scientific review of certain foods and Dietary Supplements. They concluded that there is a significant scientific consensus and specifically published permissible health words. An initial ruling allowing health claims for calcium Dietary Supplements and osteoporosis was later amended to include calcium supplements with or without vitamin D, effective January 1, 2010. Examples of the permitted wording are shown below. To meet the health requirement for calcium, Health care must contain at least 20% of the reference dietary intake, which for calcium means at least 260 mg/serving.
In the same year, the European Food Safety Authority approved Dietary Supplement's health claims for calcium and vitamin D, which can reduce the risk of osteoporotic fractures by reducing bone loss. The US FDA has also approved Qualified Health Claims (QHC) for calcium, selenium, and chromium picolinate for various health conditions, which have scientific evidence but do not meet the more stringent "significant scientific agreement" criteria required for authorized health claims. If Hard capsules choose to make such a claim, the FDA specifies the exact wording of the QHC to be used in labeling and marketing materials. The wording could be cumbersome: "One study suggests that selenium intake may reduce the risk of bladder cancer in women. However, another smaller study showed that the risk was not reduced. Based on these studies, the FDA concludes whether selenium supplements may reduce the risk of bladder cancer in women."
Whey protein is a popular ingredient, but products may also contain casein, soy, pea, and rice proteins. The same protein ingredients as those commercially available in Immune Supports can be incorporated into meal replacements and medical foods, but they are administered and labeled differently from supplements. In the US, "meal replacement" products are food products and are labeled accordingly. These usually contain protein, carbohydrates, fats, vitamins, and minerals. There may be claims such as "good source of protein", "low fat" or "lactose-free". It also designed to be a nutritionally complete medical food that is used under the care of a doctor or other licensed healthcare professional.

Dietary Supplement products have a crucial impact on our lives, especially in the medical and food industries. Since Dietary Supplement is so important, let's take a look at the differences between Chinese and foreign Hard capsules products and their outlook. Here are some answers.
Here is the content list:
l The differences between Chinese and foreign Dietary Supplements.
l Prospective analysis of Dietary Supplement.
Firstly, Dietary Supplement has not yet become a legal definition in China, whereas it is a legal concept in the USA. Secondly, Dietary Supplement in China is a product set that straddles health food and general food, while Dietary Supplement in the United States is the third category of product that is different from general food and medicine. Thirdly, the ingredients of Dietary Supplement in China must be essential nutrients or biologically active substances with relatively clear constitutive relationships, whereas Dietary Supplement in the US does not have such a definition. Fourthly, the purpose of the Dietary Supplement in China is to improve the health of the body and reduce the risk of disease, whereas the purpose of Dietary Supplement in the USA is to supplement dietary ingredients. Fifthly, Health food in China has the status of healthy food and therefore can claim to assist in lowering blood lipids and eliminating melasma, while Dietary Supplements in the US cannot make such claims.
The most important uncertainties in the hazard characterization of Dietary Supplement presented by the US National Research Council arise from the following issues: firstly, if animal information is used, which toxicity endpoints should be considered, and which indicators of representation should be used. Secondly, what are the differences in bioavailability and dose-response relationships between animals and humans? Thirdly, if human information is used, what are the damaging effects of use, and what are the differences between dose-response relationships. Fourth, how information on subchronic exposures can be used to estimate the risk of lifetime exposure. Fifth, how information on non-dietary route exposures is used.
The information used to determine human effect levels for the Dietary Supplement is inadequate and we should focus on using appropriate techniques to better identify and quantify these parameters, such as the use of appropriate and sensitive exposure/effect biomarkers. In addition, ULs for most nutrients are formulated in terms of body weight, whereas RDAs can be expressed in terms of energy intake or unsaturated lipid intake, which raises the question of which indicator to use. The toxic effects of nutrient requirements and excesses vary according to the life cycle, for example during pregnancy.
Information on nutrient interactions and the different exposure settings of individuals has led to the recognition that for some Dietary Supplements a single NOAEL cannot be used alone and that further understanding of population differences in nutrient interactions may be useful in conducting risk assessments and determining appropriate ULs.

Essential oils are liquid products of steam or water distillation of plant parts (leaves, stems, bark, seeds, fruits, roots and plant exudates). Expression is used exclusively for the extraction of citrus oil from the fruit peel, because the chemical components of the oil are easily damaged by heat. Citrus oil production is now a major by-product process of the juice industry. An essential oil may contain up to several hundred chemical compounds and this complex mixture of compounds gives the oil its characteristic fragrance and flavour. An essential oil may also be fractioned and sold as individual natural components. Other processing options can also produce further products that can be sold alongside essential oils. The plant parts can be extracted with organic solvents to produce oleoresins, concretes and absolutes or extracted with a near or supercritical solvent such as carbon dioxide to produce very high quality extracts. These oleoresins and extracts contain not only the volatile essential oil but also the concentrated non-volatile flavour components and these have wide application in the food and pharmaceutical industries. The solvent extraction processes are more difficult and complex than steam distillation and will normally be beyond the financial resources of most small scale processors, but supplying the raw materials to these extraction plants can be a market option.
The most important spices traditionally traded throughout the world are products of tropical environments. The major exceptions to this group are the capsicums (chilli peppers, paprika), and coriander which are grown over a much wider range of tropical and non- tropical environments. Production of spices and essential oils in these wet and humid environments brings special difficulties for crop and product management. Drying the crop to ensure a stable stored product is of particular importance, and in wet humid environments this creates the need for efficient and effective drying systems.
Children are growing and need more nutrients per kilogram of body weight than adults, but they also have smaller stomachs, which can lead to high demand for nutrients and insufficient intake. At the same time, children are also more prone to picky and fussy eaters and are more prone to nutritional imbalance, so Dietary Supplement is an effective way to regulate their diet. Here are some answers.
Here is the content list:
l Dietary Supplement should not be taken blindly, as it is not a substitute for medication.
l Dietary supplements should not be used as a substitute for daily diet either.
Choose Health food according to its ingredients; follow the label instructions. Do not take it at the same time as similar nutrient supplements to avoid overdose. It is also wrong to forget to take it today and take a double dose tomorrow. Dietary supplements or healthy food should not be taken as a panacea for all diseases. It is not a substitute for medication in the prevention and treatment of disease.
First of all, you should eat a balanced diet and get the necessary nutrients from a balanced diet. Under normal circumstances, if you eat a well-balanced and well-absorbed diet, you will not be deficient in any nutrients and you certainly do not need to take supplements. Some people should take appropriate supplements if for some reason they are poorly absorbed or have increased nutrient requirements. Breastfeeding should be preferred for infants, but vitamin D preparations can be added as appropriate, as breast milk is relatively low in vitamin D. When breastfeeding is not possible for specific reasons, infant formula should be the mainstay, with a gradual transition to a more varied diet; health food is not recommended for infants under 3 years of age. If Dietary Supplement is to be consumed, care should be taken to check the contents of the label under "Unsuitable Groups" and "Precautions".
Children and adolescents should choose Hard capsules based on a balanced diet, adequate exercise, and sufficient sleep, with priority given to essential and easily deficient nutrients, such as vitamins and minerals. For children with a poor appetite, anorexia, growth retardation, short stature, or susceptibility to infections, zinc-rich foods or Dietary Supplements can be used in moderation; for children who do not like to eat vegetables, Dietary Supplement with vitamin C can be used. Ingredients such as deep-sea fish oil, algal oil docosahexaenoic acid, and phosphatidylserine. Or ingredients that can protect the eyes and relieve visual fatigue, such as lingonberry extract, lutein, beta-carotene, etc.
