Flavored low-fat white mushroom crisp chip and preparation method thereof

Abstract

The invention belongs to the technical field of food processing and specifically relates to a flavored low-fat white mushroom crisp chip and a preparation method thereof. The flavored low-fat white mushroom crisp chip comprises the following materials in parts by weight: 1000 parts of white mushrooms, 5-10 parts of konjac glucomannan, 10-80 parts of chitosan, 10-60 parts of salt, 60-200 parts of isolated soybean protein and 40-200 parts of a nutrition balancing agent. The preparation method comprises the following steps: pre-treating the white mushrooms, preparing impregnation liquid, carrying out vacuum soaking and ultrasonic coating, carrying out quick-freezing and slicing, carrying out vacuum frying and dehydrating, removing oil, and packaging. The prepared flavored low-fat white mushroom crisp chip has the advantages of being low in fat content, uniform in color, crisp in mouthfeel, full in nutrition, complete in product shape and almost free of fractures.

Description

technical field

[0001] The invention belongs to the technical field of food processing, and in particular relates to flavor and low-fat white mushroom chips and a preparation method thereof. Background technique

[0002] Edible fungus is a nutritious food that is deeply loved by consumers. At present, the distribution forms of edible fungi in the market are mainly fresh products, dried products, pickled products and canned products. The product processing methods are simple, the form is single, and the output value of deep processing is low. Crispy chips are a kind of snack food with crispy taste and unique flavor, which is loved by consumers, especially young people, and has a broad market prospect. Compared with common fruit and vegetable raw materials, edible fungus has a soft tissue and is not easy to form. Therefore, edible mushroom crisps rarely enter the market as snack food. Analysis of edible fungus crisps on the market shows that the product has the following def...
