Abstract

The invention relates to a freshness-preserving agent used for quick-frozen foods. The freshness-preserving agent comprises the following raw materials in parts by weight: 50-80 parts of propolis extract, 30-45 parts of sodium alginate, 20-35 parts of tea polyphenols, 30-45 parts of lotus leaf extract and 10-15 parts of okra extract; and the freshness-preserving agent is used as a core material for preparing microcapsules with wall materials. The freshness-preserving agent disclosed by the invention is used as a freshness-preserving agent for the quick-frozen foods, and the freshness-preserving agent is free of toxic and side effects; the freshness-preserving agent is capable of prolonging shelf lives of the quick-frozen foods, and has highly effective effects of resisting bacteria and resisting oxidation. The freshness-preserving agent is safe and free of pollution to the environment. On the basis of ensuring original nutrients of the quick-frozen foods, the freshness-preserving agent further provides nutrients, including flavonoid compounds, pectin and the like, to the quick-frozen foods; thus, the quick-frozen foods have the effects of strengthening the stomach and the intestines, nourishing Yin and Yang, improving human body immunity, resisting senescence and scavenging free radicals.

Description

technical field [0001] The invention relates to the field of food, in particular to a high-efficiency antibacterial, anti-oxidation, safe and non-toxic side effect preservative for quick-frozen food. Background technique [0002] Quick-frozen food is quick-frozen food processed at a rapid low temperature (below -18°C). The water and juice in the food tissue will not be lost, and at such a low temperature, microorganisms will basically not reproduce, and food safety is guaranteed. Quick-frozen food Fast Frozen Food is the food that needs to be quick-frozen. After proper pre-treatment, it is quickly frozen in various ways, and it is packaged and stored at -18°C—-20°C (general requirements, different foods require different temperatures) at a consistent low temperature. The biggest advantage of low-temperature products delivered to the place of consumption under certain conditions is to completely preserve the original quality of the food at low temperature (reduce the heat ins...
