Embodiment 1

[0030] (1) Weigh the following components in the following parts by weight:

[0031] Camphor Polyphenols 20 parts by weight

[0032] 80 parts by weight of soybean lecithin;

[0033] (2) Mix and stir the above camphor polyphenols and soybean phospholipids evenly to obtain the phospholipid polyphenol antioxidants.

[0034] The camphor polyphenols can also include tea polyphenols, pine polyphenols, bamboo polyphenols and soybean polyphenols, including anthocyanins, proanthocyanidins, phenolic acids, catechins, epicatechin, white Veratrol, flavonoids and lignans.

[0035] The above-mentioned soybean phospholipids include phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, phosphatidic acid, lysophosphatidylcholine, glycerophospholipids, sphingomyelin, esterified sterol glucoside, sterol glucoside, Cerebrosides, phosphosides, gangliosides, monogalactosyl diglycerides and digalactosyl diglycerides.

Embodiment 2

[0037] The phospholipid polyphenol antioxidant obtained in embodiment 1 is carried out lard antioxidation test, and the samples to be tested and the label in the experiment are as follows:

[0038] A——(Camphor polyphenols: SP80=1:3) Content in lard: 0.50%, add water in lard: 1.0%;

[0039] B——The content of the phospholipid polyphenol antioxidant in embodiment 1 in lard is: 0.50%, supplemented water in lard: 1.0%;

[0040] C——(Camphor polyphenols: SP40=1:3) content in lard: 0.50%, add water in lard: 1.0%;

[0041] D——(Camphor polyphenols: SP80:SP40=5:1:2) content in lard: 0.50%, supplemented water in lard: 1.0%;

[0042] E - lard blank;

[0043] F—Camphor polyphenols: content in lard: 0.50%, add water in lard: 1.0%;

[0044] G——BHT: content in lard: 0.15%;

[0045] The initial antioxidant oxygen value of the lard in the above sample to be tested was 0.33 mg / kg, and the test temperature was 80°C.

[0046] The experimental data are shown in the table below:

[0047] ...

Embodiment 3

[0050] A batch of pig feed (hereinafter referred to as "feed") produced by a large-scale feed factory in Hunan without adding any antioxidant was used as the anti-oxidation experiment of the phospholipid polyphenol antioxidant of the embodiment. The preparation of the sample to be tested is shown in the following table:

Abstract

The invention discloses a phospholipid polyphenols anti-oxidant and preparation method thereof. The phospholipid polyphenols anti-oxidant comprises the following components in part by weight: 10 to 40 parts by weight of plant polyphenols and 60 to 90 parts by weight of phospholipid. According to the invention, the plant polyphenols and the phospholipid are prepared into the phospholipid polyphenols anti-oxidant; and the phospholipid polyphenols anti-oxidant can be uniformly dispersed in various fats and oils in an emulsified manner, plays a role of oxidation resistance to fats and oils, and ensures that fats, oils, vitamin, carotene and other nutritional ingredients contained in food, fodder and the like do not spoil easily, so that the storage life can be prolonged.

Description

technical field [0001] The invention belongs to the field of animal feed antioxidants, and in particular relates to a phospholipid polyphenol antioxidant and a preparation method thereof. Background technique [0002] Synthetic antioxidants are added to animal feed to prevent premature oxidative rancidity of animal feed and to prolong the shelf life. However, the antioxidant properties of the existing antioxidants are not ideal, and the extension of the shelf life of animal feed is limited. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a phospholipid polyphenol antioxidant and a preparation method thereof. [0004] Technical scheme of the present invention is as follows: [0005] A phospholipid polyphenol antioxidant, comprising the following components by weight: [0006] 10-40 parts by weight of plant polyphenols [0007] Phospholipids 60-90 parts by weight. [0008] In a preferred emb...
