Example Embodiment

[0029] Example 1

[0030] A method for removing aflatoxin in peanut oil, comprising

[0031] A Material selection process:

[0032] First, distinguish the origin of the raw materials, choose high-quality peanuts as a batch of 200 tons, and conduct sampling inspections before they are shelled and changed into rice, such as: water impurities, aspergillus flavus, acid value, peroxides, oil content and other indicators for laboratory testing , Make a record; after passing the test, it will be accepted and put into storage.

[0033] Use a specific gravity stone remover to separate and clean the dust, earth and rocks, metals, impurities, etc. in the fruit; use a hulling machine to separate large and small fruits according to specific gravity levels to reduce the damage of peanuts. Ensure that the damage rate is around 5%, and put the changed semi-finished peanuts into the warehouse.

[0034] B Peanut Grading Screening:

[0035] Firstly, check the opening of the bag, arrange the raw material ...

Example

[0041] Comparative Example 1: The material selection process and the peanut grading and screening process are exactly the same as those in Example 1. The feeding and oil extraction process is different, and the steps (2) and (3) are not included, that is, no compound enzyme preparation is added.

[0042] The experimental results are shown in Table 1 The treatment effect of compound enzyme on aflatoxin:

Abstract

The invention provides a method for removing aflatoxin out peanut oil. The method comprises the following steps: A, selecting materials; B, grading and screening peanuts; and C, feeding and squeezing oil, The method is characterized in that aflatoxin is removed by means of a compound enzyme in the step C, wherein the compound enzyme consists of phospholipase A1, laccase, neutral proteases, xylanases by adding phospholipase A1, laccase, neutral proteases and xylanases respectively according to proportions of 0.3g/kg, 0.2g/kg, 0.5g/kg and 0.1g/kg; then hydrolysis is carried out at 42 DEG C for 5-6 hours; and finally the pH of hydrolyzate is adjusted to 6.8. According to the method, aflatoxin is removed by a biological method, reaction conditions are mild and operation is simple, aflatoxin content meets national standards, and the method disclosed by the invention has a broad application prospects.

Description

[0001] technical field The invention belongs to the technical field of biochemistry, and in particular relates to a method for removing aflatoxin in peanut oil. Background technique [0002] my country is one of the most important major peanut producing countries in the world, with an output of more than 40% of the world's total output. According to statistics, the annual output of my country's peanuts has reached 15.22 million tons, surpassing that of soybeans (15.2 million tons), and has become the first oil crop in my country. The total output, per unit yield and export volume all rank first in the world. Peanut oil is the most edible and consumed edible oil by ordinary people in our country, but the safety of edible oil based on peanut oil is not optimistic. Aflatoxin contamination of peanut oil is a worldwide problem, and it is the biggest and most important risk faced by peanut oil export and consumption. Aflatoxin is a secondary metabolite produced by Aspergillus flav...
