Abstract

The invention discloses a preparation method of food anti-oil paper, and belongs to the field of paper making. The preparation method comprises the following steps: taking corn starch, water, alpha-amylase and calcium acetate, carrying out enzymatic hydrolysis and enzyme deactivation to obtain a zymolyte, taking 2,2,6,6-tetramethylpiperidinooxy, the zymolyte, sodium hypochlorite and sodium bromide, carrying out stirring and mixing to obtain a mixture, adding the mixture into an acetic acid buffer solution according to a mass ratio of 1:(60-70), carrying out stirring and mixing for 18-24h, introducing nitrogen gas, adding sodium periodate with a mass of 50-60% of the mass of the acetic acid buffer solution, carrying out heating to 40-50 DEG C, carrying out heat preservation for 3-5 hours, carrying out filtering, carrying out dialysis on the filter residue, carrying out freeze-drying to obtain a freeze-dried product, taking the freeze-dried product, adding water according to a mass ratioof 10:3, carrying out mixing by stirring for 30-40 min at a temperature of 55-65 DEG C to obtain a mixed liquid, taking the mixed liquid, coating a base paper surface of anti-oil paper according to acoating amount of 12-15 g/dm<2>, and carrying out drying to obtain the food anti-oil paper.

Description

technical field [0001] The invention belongs to the field of packaging materials, and in particular relates to a preparation method of food greaseproof paper. Background technique [0002] Packaging materials usually refer to the general term used to manufacture packaging containers and packaging transportation, packaging decoration, packaging printing, packaging auxiliary materials and packaging-related materials. Among them, as an important part of packaging materials, packaging paper plays an important role in the entire packaging industry. status. Wrapping paper is a kind of paper mainly used for packaging purposes. It is an important basis for developing packaging technology, improving packaging quality and reducing packaging costs, and is indispensable for human life. With the rapid growth of the national economy and the continuous improvement of the quality of life, my country has developed rapidly in the field of packaging paper. In order to make full use of natura...
