Protein composite edible film for fried food and preparation method thereof

Abstract

The invention discloses a protein composite edible film for fried food and a preparation method thereof. During preparation of the film, distilled water is used as a solvent, the content of pig plasmaprotein powder is 8% (w / w), the content of ovalbumin powder is 3% (w / w), the addition amount of glycerol is 20% of the total mass of the protein powder and the ovalbumin powder, a uniform and stableliquid is prepared through magnetic stirring and ultrasonic dissolution promotion, and film treatment is carried out before food is oiled. Through testing of the fried meatballs, the protein compositefilm can effectively reduce oil content and water loss, and the defect of high oil content of the fried food can be effectively improved while the crispy outside and tender inside taste of the friedfood is guaranteed. According to the invention, the problem that fried foods are easy to absorb oil is efficiently solved, and the effect of the composite film is better than that of a single-component film.

Description

technical field [0001] The invention relates to a protein composite edible coating film for fried food and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Fried foods are high in fat content, so regular consumption may lead to excessive intake of fat and cause health risks. In order to produce food with low fat content, a large number of physical methods have been tried, such as oil-absorbing paper, high-temperature and high-speed airflow, vacuum frying and water-oil mixed frying methods. During the frying process, there are three ways for oil to be absorbed. One is that after the water in the food escapes in the state of water vapor, the pores produced are filled and replaced by oil; the other is that when the food is fried, the water vapor in the surface pores condenses and causes The vapor pressure decreases, and the oil attached to the surface of the food is absorbed by the small pores through the "capilla...

AI Technical Summary

Problems solved by technology

At present, there are many studies on plant protein, but there are disadvantages such as unsatisfactory solubility, easy to cause human allergies, and weak ability to protect water. At this time, animal protein has entered people's field of vision, such as whey protein, myofibrillar protein, etc. , and they have higher nutritional value. Although there are few studies on animal protein edible coatings, the prospect is promising
