Food Additives In Food Industry

Types of food additives increase year by year with the progress of science, food additives function categories are acidity regulation agent, anti-knot agent, antifoaming agents, anti-oxidant, bleach, bulking agents, based agent material in the rubber base candy, coloring agent, colour fixatives, emulsion agent, enzyme preparations, increased taste agent, flour treatment agents, coating agent, humectants, nutrition enhancer, preservatives, stabilizer and coagulators, sweeteners, thickeners, food flavours & aromas, etc.

The habit of read product labels carefully need to be developed. Food labels on food packaging are text, graphics, symbols and all about that. They present as description of food quality, security attributes. They guide consumers to buy the right food and play a promotional role. Food is essential to maintain life, the supply of calories and nutrients can meet human needs. When people go to the supermarket, variety of processed foods filled with shelves. And in the list of ingredients of the food people will find that most of them contain food additives. All areas of food processing can not be without food additives in everyday life, such as grain and oil processing, spices processing, snack foods, fruit and vegetable fresh-keeping and so on. Despite its content in food is less than 2%, but it plays an extremely important role in improving the food color, aroma, taste and food processing conditions, as well as extending the shelf life and adjust nutrition structure.

If there is no preservative in food, many harmful micro-organisms will quickly multiply, and the harmful microbial contamination will lead to food safety incidents. Food additives are common in our life. But mention of food preservatives, many consumers are wary. In fact, there are many kinds of food preservatives. The correct use of food additives are nonpoisonous to human body. Its function is to change the flavor and sensual of foods. Ideal food additives should be benefit. During the large volume processing, food additives also help ensure uniformity of product quality. There have strict rules about the use and the types of food additives. For example, lemon yellow is allowed to add to drink, but it is beyond using range when it is added to steamed buns, and that is not allowed. As a result, consumers should treat to food additives in a rational attitude.

However, some businesses or individuals use excessive additives or industrial additives to get the maximize benefits. This may mislead some people think the food additives has become the greatest threat to food safety. But industry additives or illegal additives are not food additives.

The Use Of Food Emulsifier

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.

What is Guar Gum?

Guar gum is a natural food thickener and a traditionally cultivated plant in  the northern regions of India and Pakistan. Guar in India is drought resistant and is very hardy. Guar gum is extracted from the legumes-Guar. The molecular weight of guar gum is the largest one in all natural water soluble polymers. Guar gum in fact is not just a thickening agent, but a binder and emulsifiers as well. Guar gum has the natural ability to bind with water molecules, preventing them from forming the unwanted crystals.

White to yellowish brown powder. It disperses in hot or cold water to form the viscous liquid and is the highest viscosity of natural rubber. 1% aqueous solution viscosity of about 4-5Pa • s. It transformed into gels when add a small amount of sodium tetraborate. The viscosity changes with the change of PH value.

Application of guar gum in food industry:

1 It used as stability agent in ice cream.

2 It prevent noodles from bonding, water retention and increasing flexibility, and it maintains excellent quality and extend shelf life.

3 It is water retention and thickening stabilizer when applied to beverages such as peanuts milk, orange juice, fruit tea.

4 It can increase the volume in meat products such as sausages, lunch meat, meat balls.

5 It can reduce spills, control consistency and prevention of fat transfer in baby food and canned food.

As a food additive, the safety of guar gum has been recognized by the World Health Organization. Guar gum contains several nutrients, and common microorganisms can grow and reproduce in it. If you want to use the configured guar gum solution for a period of time, you must make a good anti-corrosion measures. The molecular structure of guar gum changes more, its resistance to microbial invasion is greater. Tests showed that in terms of resistance to microbial invasion the derivative of guar gum is far more than the guar gum. Practice also shows that the derivative of guar gum can keep the solution longer stability and good quality. As a result, the derivative of guar gum can inhibit the growth of bacteria, and these bacteria can destroy the stability of guar gum solution and reduce the quality of solution.

Because of the low price and the stable source, guar gum has been widely used in food industry. In recent years, the dispersion, viscosity and solution transparency of guar gum has been rapidly risen by the chemical modification. The study and development of the derivative of guar gum makes it becomes an important composition in the production of guar gum.
