Performance Characteristics and Functions of Common Food Additives

What are food additives?

Food additives are an important component of modern food industry. They play a crucial role in improving the color, aroma, taste, nutritional value, quality, processing conditions, shelf life, and preventing food spoilage. As a result, the food additive industry occupies an important position in modern food industry.

Definition and function of food additives

Definition of food additives

Food additives refer to artificially synthesized or naturally occurring substances added to food for improving food quality, color, aroma, taste, nutritional value, and processing needs such as preservation.

Function and development trends of food additives

a) The main functions of food additives are:

i) Improving food quality and enhancing food taste, color and texture according to the public's needs;

ii) Making food manufacturing process more reasonable, hygienic, and convenient, and encouraging the mechanization, automation, and scaling up of food industry;

iii) Saving resources and reducing cost for food industry while greatly enhancing food quality, grade, and added value, and producing evident economic and social benefits.

b) Trends in the development of food additives include:

i) Developing natural, nutritional, and multifunctional food additives;

ii) Devoting to the development of diversified and specialized additives.

Types of food additives

Food additives can be classified into natural food additives and artificially synthesized food additives based on their sources. According to their functions, they mainly include: nutrient fortifiers, preservatives, antioxidants, thickeners, emulsifiers, chelating agents (including stabilizers and coagulants), quality improvers, seasonings, colorants, edible flavors, and spices.

Food preservatives

Food preservatives are a kind of additives used to inhibit food decay and spoilage, prolong storage and preservation periods, and maintain freshness. Currently, the commonly used food preservatives mainly include four categories: benzoic acid and its salts, sorbic acid and its salts, propionic acid and its salts, and parabens.

Food emulsifiers and thickeners

Food emulsifiers and thickeners are additives that improve and stabilize the physical properties of food components or improve the food structure state. They play an important role in the "shape" and "quality" of food, as well as processing properties.

Seasonings

Seasonings mainly include sour taste agents, sweeteners, saltiness agents, and bitterness agents (with limited application). In China, saltiness agent (usually using table salt) is not considered a food additive.

Food colorants

Additives used for coloring food are called food colorants, which aim to increase food preference and stimulate appetite. Food colorants can be divided into two categories according to their sources: artificially synthesized colorants and natural colorants.
