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.

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.

Plant oil is a compound made from unsaturated fatty acids and glycerol chemistry and is the oil obtained from the fruits, seeds, and germ of plants, such as peanut oil, soybean oil, flax oil, and castor oil, rapeseed oil, etc. Plant oil is obtained from oil-rich plant seed kernel as raw material, after a series of pretreatment, and then extracted by mechanical pressing or solvent leaching to obtain crude oil, which is refined. It is effective in providing energy, supplementing nutrition, treating constipation, and enhancing memory.

l Nutritional value
Plant oil can provide energy for the body. Plant oil contains protein and carbohydrates, which are good for the health of the body. It is also very healthy to choose plant oil when frying, and it is not easy to cause the body to gain weight.
Plant oil contains a variety of unsaturated fatty acids and vitamins, often eat plant oil, you can supplement a variety of nutrients, and eat a healthy body. Plant oil is rich in vitamins A, E, D, and K. They can meet the body's need for vitamins. Vitamin A can prevent night blindness, vitamin E can fight age, vitamin D can prevent rickets, and vitamin K is vital to the blood clotting system. In addition, plant oil is also rich in calcium, iron, potassium, and many other trace elements. Calcium is self-evident to the human body and can prevent osteoporosis, iron can prevent iron deficiency anemia, and potassium can stabilize blood pressure.
Plant oil has a digestive effect, the role of lubrication, eating is often dry and easy to form constipation, heat some plant oil can play the role of lubrication, can effectively treat constipation.
Plant oil contains vitamin E, as well as a certain amount of zinc, choline, and other components, which can help enhance memory, delay the decline of brain function, and effective anti-aging.
Plant oil is mainly composed of unsaturated fatty acids, which is different from the saturated fatty acids in animal oil. Unsaturated fatty acids will lower fat and cholesterol, which helps prevent high blood cholesterol. By the same token, plant oil is rich in unsaturated fatty acids, which can stabilize blood lipids, soften blood vessels and prevent atherosclerosis.
Plant oil mainly contains vitamin E, vitamin K, calcium, iron, phosphorus, potassium, other minerals, fatty acids, and so on. The fatty acids in plant oil can make the skin moist and shiny. The main components of palm oil and coconut oil in plant oil are saturated fatty acids, which are the same as animal fats, so they are solid at room temperature. Most plant oils, such as peanut oil, safflower oil, mustard seed oil, corn oil, flaxseed oil, nut oil, hemp oil, soybean oil, and sunflower oil, are composed primarily of unsaturated fatty acids and are therefore liquid at room temperature. It is recommended to consume those plant oils that are mainly composed of monounsaturated fatty acids. Plant oils rich in monounsaturated fatty acids include mustard seed oil, olive oil, and peanut oil. Plant oils that are high in polyunsaturated fatty acids include corn oil, safflower oil, soybean oil, sunflower seed oil, and sesame oil, all of which have a unique flavor.
The above is all the explanation of the benefits of plant oils for people in this article, and I hope it can help you to have a deeper understanding of plant oils.
More and more people are choosing Fish oil as a health product, but in the process of buying it, many consumers still have many questions about how to get the real deal and good quality Fish oil. Here, we would like to introduce you to a few ways to choose Fish oil. How do we choose?
This is the list of contents：
·Look at the origin
·Selecting raw materials
·Look at the appearance
·Smell
·Look at the certification mark
·Low-temperature test
Fish that live in the northern hemisphere generally have more w-3 fatty acids in their bodies, while fish from the southern hemisphere is relatively lean. Currently, the only two areas with the best-preserved natural environment are the Lower Norwegian Sea to the Barents Sea and the Labrador Sea, which naturally produce the highest quality Fish oils. Other regions, such as Australia and New Zealand, are over-exploited due to tourism, so the quality of Fish oil has also been affected to some extent.
Small fish at the bottom of the food chain usually contains fewer contaminants, while larger fish at the top of the food chain accumulate more toxins, so the best sources of Fish oil are small fish such as sardines, rather than salmon, mackerel, seals, etc.
Good Fish oil capsules are uniform in size and free from impurities. Good quality Fish oil capsules should be on the softer side and have no coloring agents added. They are pale yellow, crystal clear and have a very good body, and are not cloudy. A soft Fish oil capsule will not get stuck in the throat and is a better experience, while those capsules that are large and hard are often difficult to swallow and even require the capsule to be broken to pour out the Fish oil before it can be taken.
It is normal for Fish oil capsules to have a slight fishy smell, but if it smells heavy and feels a little top-heavy, it means that there is a problem with the quality and it is likely to be oxidized and spoilt.
If the product has a blue cap, it means that the quality of the product and the efficacy claimed on the packaging are recognized by the state and can be purchased with confidence.
Good Fish oil with a high proportion of EPA and DHA will not condense easily and will quickly return to a liquid state at room temperature, even if it condenses into a solid-state in extremely cold conditions, whereas a Fish oil with a low proportion of EPA and DHA will take longer to return to a liquid state. Therefore, to distinguish between good and bad Fish oil, the first Fish oil to return to liquid form after condensing in the freezer is the one with the highest purity of EPA and DHA.
These are just a few suggestions on how to buy Fish oil for reference. I believe that through this small science, we all have a certain understanding of how to select Fish oil. I hope that in the future when you choose Fish oil products, you can refer to the above six suggestions and buy safe, high-quality Fish oil products to protect the health of your family and friends!
Scientists are studying omega-3s to understand how they affect health. People who eat fish and other seafood have a lower risk of several chronic diseases. But it is not clear whether these health benefits come from simply eating these foods or from the omega-3s in these foods. Here are some examples ofwhat the research has shown.
Cardiovascular disease
Many studies show that eating fatty fish and other types of seafood as part of a healthy eating pattern helps keep your heart healthy and helps protect you from some heart problems. Getting more EPA and DHA from foods or dietary supplements lowers triglyceride levels, for example.
The American Heart Association (AHA) recommends eating one to two servings of seafood per week to reduce your risk of some heart problems, especially if you consume the seafood in place of less healthy foods. For people with heart disease,the AHA recommends consuming about 1 g per day EPA plus DHA, preferably from oily fish, but supplements are an option under the guidance ofa healthcare provider. The AHA does not recommend omega-3 supplements for people who do not have a high risk of cardiovascular disease.
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.
