Edible oil filter paper and preparation method thereof

Abstract

The invention discloses edible oil filter paper and a preparation method thereof. The preparation method comprises the following steps: 1) defibering and mixing 20-40 parts of wood pulp fibers and 40-60 parts of viscose uniformly for 30 min or more, and pulping the mixture for over 60 min to obtain fiber raw material slurry; 2) mixing the fiber raw material slurry, 0.1-5 parts of a dispersant, 1-10 parts of a wet strength agent and 5-15 parts of an acrylic emulsion with water uniformly to obtain slurry; 3) fully and uniformly mixing the slurry with a fibrous binder, and inputting the mixture in a paper maker to prepare raw paper; 4) applying an adhesive to the raw paper, and during and rolling the raw paper to obtain a filter paper main filter layer; and 5) paving a filter paper guide layer on the filter paper main filter layer and paving a semi-transparent film layer for precise filtration below the filter paper main filter layer. The invention aims to provide the edible oil filter paper which has the characteristics of being high-temperature-resistant, high in average voidage, good in filtering and absorbing property, long in service life, high in dry and wet strength and uniformin paper and the preparation method thereof.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, in particular to edible oil filter paper and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the processing of food is no longer limited to home cooking, and the wave of enterprise production of food has swept the world. In the food processing industry, fast food and fast-food fried food have the fastest growth rate, especially Western-style fast food led by McDonald's and KFC, and Chinese-style noodle fast food represented by Master Kong and Uni-President. These fast foods use a large amount of edible oil, and are repeatedly used, and food residues will inevitably be produced during the frying process, so the edible oil must be precipitated and filtered after being used for a period of time. Moreover, food residues in oil will undergo oxidation, hydrolysis, polymerization and ...

AI Technical Summary

Problems solved by technology

Moreover, food residues in oil will undergo oxidation, hydrolysis, polymerization and other reactions after repeated high-temperature frying, which will increase the acid value and peroxide value of edible frying oil, causing oil deterioration

Such processed food will also cause harm to the health of the eater. In addition, the long-term high temperature will cause the decomposition of polymer compounds and increase the acidity of the oil, which limits the shelf life of fried food. Therefore, high-temperature edible oil filter paper must be used for filtration.
