We like to pay attention to the color,
aroma, taste, form and structure of food, but harmless and nutritional is also
important. As a food additive, safety is the most important condition, then is
the process and performance. Therefore, the general requirements for food
additives and their usage are:
1 The toxicological assessment on food
safety should be fully proved. Make sure that the food additives are
nonpoisonous and harmless to the human body in the limited long-term ingestion.
2 Food additives would be involved in the
body's normal metabolism, or it can be excreted out totally by a normal process
of detoxification detoxify. They can not be broken down in the human body or
have effects with food ingredients to form harmful or poisonous substances.
3 Food additives should have strict hygiene
standards and quality standards.
4 Food additives should not destroy the
nutritional ingredients of food, as well as the quality and flavor of food.
5 Food additives should be helpful to the
food production, processing, fabrication and storage processes. It needs to
keep food nutrition, prevent food spoilage, enhance food sensory properties,
improve product quality and has a significant effect at a relatively low usage conditions.
No matter it is natural or synthetic food
additives, they are essentially chemicals. Different food additives belongs to
different types of chemical substances, and emulsifying agent is widely used in
food processing. Emulsion agent can stable the food physical state, improve
food organization structure and extend shelf life. Some common food ingredients
are mutually not compatible and uneven mix of each component that leads to the
food oil-water separation. But food emulsifying agent can solve these problems
or phenomena.
The amphiphilic character of emulsifier
molecules, it can have specific interactions with food carbohydrates, proteins,
lipids, etc. With the development of the food industry and the diversity of
processed food, countries around the world have attached great importance to
the development of food emulsifier in research, production and application.
Nowadays, food emulsifiers are serialized, versatile, efficient, easy to use.
The variety of food emulsifiers is
relatively stable, but the endless new foods and new food processing technology
is more and more. From the viewpoint of ease of use, food emulsifying agents
are transitioned from bulk products to the powder or liquid products. With the
development of the food processing industry, food emulsifier application has a
great development. Due to the developed food industry and the large proportion
of meat products and dairy products, so the use amount and variety of food
emulsifier is more and more. Article source: http://okfoodadd.blogspot.hk/2015/09/what-is-guar-gum.html.
