Abstract

The invention relates to the technical field of food preservation, and discloses a composite natural preservative and a preparation method thereof, and the composite natural preservative comprises the following main components: 1-4 mg / mL of tea saponin, 3-5 mg / mL of tea tree oil nano emulsion, and 10-20 mg / mL of chitosan. The composite natural preservative disclosed by the invention is prepared from green and environment-friendly raw material components which are compounded according to a reasonable proportion, so that the raw material components have a synergistic effect, the preservation effect is better, and the condition and the quality of food can be ensured; the composite natural preservative disclosed by the invention is in an aqueous solution type, so that active ingredients are not easy to volatilize, a finished product is convenient to store or transport, and the composite natural preservative is convenient to use, good in safety and low in raw material cost; in addition, the composite natural preservative is simple and reasonable in preparation method, easy to operate, free of toxic solvents in the preparation process, healthy, harmless, green, environmentally friendly, stable in product property, lasting in preservation effect and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of food preservation, and more specifically, to a composite natural preservation agent and its preparation method and application. Background technique [0002] Hainan Shuzicai, also known as Wuzhishan Wild Vegetables, Tianluxiang, and Lulancai, belongs to the Euphorbiaceae family and is a small perennial shrub. It is easy to grow, more drought-resistant, less pests and diseases, long life, crispy taste, high nutritional value, rich in protein, vitamins and minerals, and its protein and vitamin C content is 20 times that of ordinary vegetables Above, carotene and vitamin B 2 The content is more than 10 times that of ordinary vegetables. Aberdeen is eaten by picking young shoots. After being fried or boiled, the taste is tender and crisp, and the taste is delicious and unique. Therefore, as a rare and large-scale domesticated wild vegetable that integrates food and therapeutic functions, it has played an im...
