Embodiment 1

[0025] In an embodiment of the present invention, a biological preservative for inhibiting rancidity of refined lard comprises the following materials in weight percentage: 17.64% of walnut green bark polyphenols crudely extracted from ethanol, 68.32% of tea polyphenols, and 14.04% of vitamin E.

[0026] Further, a preparation method of a biological preservative for inhibiting the rancidity of refined lard comprises the following steps:

[0027] S1: Crude walnut green peel polyphenols, tea polyphenols, and vitamin E were ground through a 100-mesh sieve in sequence to obtain ethanol crude walnut green peel polyphenols powder, tea polyphenols powder, and vitamin E powder;

[0028] S2: put walnut green peel polyphenol powder, tea polyphenol powder, and vitamin E powder into a high-mixer and mix them to obtain a mixed powder;

[0029] S3: putting the mixed powder into a dryer for drying, and packing after cooling to obtain a finished biological preservative.

[0030] Further, the...

Embodiment 2

[0040] Completely prepared according to the steps of Example 1, the difference from Example 1 is: a biological preservative to inhibit the rancidity of refined lard, including the following materials in weight percentages: 18.23% of walnut green bark polyphenols crudely extracted by ethanol, tea polyphenols 60.72%, Vitamin E 12.07%.

Abstract

The invention relates to the technical field of anti-rancidity preservatives for lard oil, in particular to a preparation method of a biological preservative for inhibiting rancidity of refined lard oil, and the biological preservative is prepared from the following materials in percentage by weight: 16.78-18.23% of walnut green seedcase polyphenol coarsely extracted by ethanol, 60.72-71.35% of tea polyphenol and 12.07-15.13% of vitamin E. The polyphenol extracted from the walnut green seedcase is compounded with the tea polyphenol and the vitamin e to form a natural biological preservative, so that the natural biological preservative conforms to the conflict of modern people on chemical food additives and the pursuit of modern people on health, has no side effect, and effectively solves the problem that the existing antioxidant contains chemical components and causes harm to human bodies. Meanwhile, the walnut green seedcase polyphenol coarsely extracted by ethanol, the tea polyphenol and the vitamin E are matched, so that relatively high oxidation resistance is achieved, an excellent effect on rancidity of the lard oil is achieved, the storage period of the lard oil is effectively prolonged, and the eating safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lard anti-rancidity preservatives, in particular to a preparation method of a biological preservative for inhibiting the rancidity of refined lard. Background technique [0002] Lard, also known as lard or lard in Chinese. It is extracted from pork. The initial state is a slightly yellow translucent liquid edible oil. BHT, BHA, etc. [0003] However, some studies in this year have found that chemical antioxidants are carcinogenic, embryo teratogenic and cytotoxic, and long-term use can cause damage to human internal organs and the emergence of cancer. [0004] Therefore, those skilled in the art provide a method for preparing a biological preservative for inhibiting rancidity of refined lard, so as to solve the problems raised in the above-mentioned background technology. Contents of the invention [0005] The object of the present invention is to provide a kind of preparation method of the biopreser...
