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.
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
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.
Health food is a supplement based on vitamins, minerals, and extracts with a relatively clear structure-activity relationship, which is taken orally to supplement essential nutrients and bioactive substances to improve health and reduce the risk of disease. The following Dietary Supplement manufacturers will introduce you to the characteristics and requirements of Dietary Supplements. Here are some answers.
Here is the content list:
l What are the characteristics of Dietary Supplements?
l What requirements must a Dietary Supplement meet?
The raw materials used in Dietary Supplement are mainly taken from natural species, but there are also safe and reliable substances produced through chemical or biological technology, such as plant and animal extracts, vitamins, minerals, amino acids, etc. Generally speaking, the physical and chemical properties of the functional ingredients are relatively stable, the chemical structure is relatively clear, the mechanism of action has been scientifically proven to a certain extent, and the safety, functionality, and quality control meet the regulatory standards.
Dietary Supplement is mainly available in the form of pharmaceutical-like products in the following dosage forms: hard capsules, soft capsules, tablets, oral liquids, granules, powders, etc. The packaging forms are pre-packaged in bottles, drums (boxes), bags, and aluminum blister packs.
Immunity increases with the status of general food can follow the requirements of the "Nutritional Labelling Regulation for Food" issued by the Ministry of Health in 2008 and label the product with nutrition or nutrient function claims. Health food products approved by the health administration can only claim the specific health functions approved, and the publication of advertisements needs to be approved by the State Drug Administration. Dietary Supplement, on the other hand, can only claim to supplement (specifically) nutrients.
Firstly, Dietary Supplement containing more than three (inclusive) vitamins and minerals can only be described as a complex or multiple Dietary Supplement. The label and instructions should indicate each content, recommended intake, method of storage and precautions, etc. Thirdly, Dietary Supplements should consist of one or more vitamins or minerals in the form of tablets, capsules, tablets, or oral liquid; the daily consumption of tablets should not exceed 20 grams and the daily consumption of oral liquid should not exceed 30 ml. Fourthly, Dietary Supplements must obtain a health food approval certificate before they can be manufactured and sold. Fifthly, the excipients added to Dietary Supplements should be mainly to enhance the product's process performance or improve the taste of the product. Sixth, the raw materials and excipients in Skin care should provide their sources and quality standards; chemically synthesized Dietary Supplement raw materials should be "Hygienic Standards for the Use of Food Additives", the relevant circulars of the Ministry of Health or the Pharmacopoeia of the types of Dietary Supplement raw materials allowed to be used and comply with the corresponding provisions, otherwise, Otherwise, it should be evaluated for safety and toxicology concerning the requirements for new food resources and provide scientific proof of safe human intake.

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.

A Dietary Supplement should not be taken more than the recommended dosage or in conjunction with similar nutrient supplements to avoid adverse effects from excessive intake. Drug-nutrient interactions may affect the efficacy of drugs, cause acute or chronic drug toxicity, and may reduce the effectiveness of nutrients and should be taken into consideration when consuming the Hard capsules. In addition, people in high selenium areas should not consume selenium supplements to prevent excessive intake of selenium. So, apart from that, what else do you know about using the Dietary Supplement? Here are some answers.
Here is the content list:
l Dietary Supplement is not a substitute for the normal three meals.
l Dietary supplements should be consumed appropriately.
Dietary Supplement is not a substitute for eating three normal meals. Our diet and lifestyle habits have the greatest impact on our health. Natural foods such as vegetables, fruits, and meat contain the most comprehensive range of nutrients, so the first thing to do is to eat three well-balanced meals and get the nutrients you need from a balanced diet. Under normal circumstances, if a person has no bad habits and eats a well-balanced and well-absorbed diet, there is no shortage of nutrients and certainly no need for supplements. Some people may have poor absorption of nutrients for some reason or may need to supplement if their absorption of nutrients increases. Children have an increased need for nutrients during their growth and development and need to take appropriate supplements, especially for trace elements such as calcium, iron, zinc, and other essential amino acids. Primary and secondary school students are at a critical stage in their growth and development and have a high volume of daily studies, so they should take appropriate supplements but should follow medical advice.
The proportions of various nutrients in different foods vary greatly and some people need appropriate vitamin supplements. Zinc supplements should be supplemented with foods rich in zinc, such as meat and animal offal. When supplementing with vitamins or trace elements, it is important to pay attention to the ratio between them, when supplementing with calcium and other trace elements, it is important to pay attention to their absorption and utilization in the body. For urbanites who are not usually physically active, supplementation should be accompanied by increased exercise to promote nutrient absorption. There is a limit to the intake of nutrients beyond which Dietary Supplements can cause unnecessary trouble.

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.

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 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.

Fatty fish such as salmon, tuna and mackerel contain high levels of two omega-3 essential fatty acids (EFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EFAs have been shown to have many health benefits, including supporting cardiovascular health and helping to maintain a healthy mood.
Taking fish oil supplements, in liquid or capsule form, is one of the best ways to obtain EFAs when you can’t eat two or more servings of fresh fish per week. To avoid fishy aftertaste, try splitting up your dosage throughout the day, taking capsules with a meal or using a flavored kind.
