Food Business Network News According to the definition of GB2760, food preservatives refer to a kind of food additives that can prevent food spoilage and prolong food storage period. The inhibition of microorganisms is mainly achieved by affecting the substructure of cells. In food systems, food preservatives must not be used in foods that already contain large amounts of harmful micro-organisms to suppress spoilage, and only when the harmful micro-organisms are relatively small. In addition, food preservatives have their antibacterial spectrum. No food preservative can inhibit all harmful microorganisms that may occur. Therefore, food preservatives are usually used in combination in practical applications.
There are about 60 kinds of food preservatives used in the world, 50 kinds in the United States and 43 kinds in Japan. The food preservatives allowed in China include: benzoic acid and its sodium salt, 4-phenylphenol, calcium salt, cinnamaldehyde and diphenyl ether. There are 30 kinds of sulfur, natamycin and nisin. At present, GB2760 can be used as a preservative in baked goods and fillings and related regulations.
Moon cake is a kind of bakery food in baked goods. It is rich in sugar and oil. It is a high osmotic food with relatively low water activity Aw, but it is also susceptible to microbial contamination such as mold. Therefore, adding food preservatives to ensure the consumption of moon cakes. Security is very important. Since 2011, food preservatives that can be used for mooncakes and fillings include sorbic acid and its potassium salts, propionic acid and its sodium salts, calcium salts, dehydroacetic acid and its sodium salts, natamycin, and doubles. Sodium acetate, monocaprylin, parabens and their sodium salts, ε-polylysine, etc., and benzoic acid and its sodium salt, dimethyl fumarate can not be used for moon cake preservation. The following is a brief introduction to the application status of several preservatives in mooncakes:
Sorbic acid and its potassium salt: Sorbic acid is an acid type preservative, which has a good inhibitory effect on microorganisms in an acid medium and is suitable for food preservation of pH 5.0-6.0 and below. As the pH increases, the antiseptic effect decreases, and the preservation effect is lost when the pH is 8.0. In the baked food, the preservatives such as sorbic acid and propionic acid and calcium propionate can produce a synergistic effect and improve the antiseptic effect. By studying the effect of potassium sorbate and other environmental conditions on the growth of the genus Aspergillus on the sponge cake, the results showed that the growth of fungi was better at pH 6.0, but potassium sorbate was greatly affected by pH conditions. Many baking products (including sponge cakes) have a preservative effect when the acid-base conditions are higher than pH 7.0. By studying the antifungal effect of potassium sorbate on Spanish baked goods under neutral conditions, the results showed no significant inhibition. Under the condition of low pH value (4.5-5.5) and different water activity, the inhibitory effect of potassium sorbate on the genus Aspergillus, Penicillium and Aspergillus on baked goods was optimized.
