What are the pasta additives? What is the difference?

Food additives are a kind of chemical synthetic or natural substances used to improve food quality, prolong food shelf life, facilitate food processing and increase food nutrients. Food additives can improve the quality and nutritional value of food, improve the sensory characteristics of food, prevent food from spoilage, prolong the shelf life of food, facilitate food processing and improve the utilization rate of raw materials. At present, there are more than 20 kinds of food additives in China, such as acidity regulator, sweetener, bleaching agent, colorant, emulsifier, thickener, preservative and nutritional fortifier. It can be said that all processed foods contain food additives. Moreover, the rational use of additives is beneficial and harmless to human health and food. As long as food additives are added in food production according to national standards, consumers can eat with confidence.

The safe use of food additives is very important. The ideal food additive is preferably a beneficial and harmless substance. Food additives, especially chemically synthesized food additives, are mostly toxic, so the dosage should be strictly controlled when using them. The toxicity of food additives refers to their ability to cause harm to the body. Toxicity is not only related to the chemical structure and physical and chemical properties of the substance itself, but also related to its effective concentration, action time, contact route and location, interaction between substances and functional state of the organism. Therefore, regardless of the toxicity and dose of food additives, there is a problem of the relationship between dose and effect on human body, that is, substances will show toxic effects only when they reach a certain concentration or dose level.

In the process of green food production and processing, grade A and AA products can use food additives according to the product itself or production needs. AA-grade green food is only allowed to use natural food additives, and synthetic food additives are not allowed. However, the following products shall not be used: (1) potassium ferrocyanide (2) 4-hexylresorcinol (3) sulfur (4) potassium aluminum sulfate (5) ammonium aluminum sulfate (6) erythrosine (7) erythrosine aluminum ingot (8) erythrosine (9) erythrosine aluminum ingot (10) titanium dioxide.
