Processing method of dehydrated agaricus bisporus

Abstract

The invention discloses a processing method of dehydrated agaricus bisporus, comprising the steps as follows: getting fresh agaricus bisporus as raw materials, washing, immersing, cutting, immersing the agaricus bisporus, protecting the colour, quick-freezing, vacuum-freezing and drying the agaricus bisporus, selecting, metal-detecting and packaging the same. In the immersing and colour protecting process, the colour retention agent is composed of the following components according to mass percent: 0.1-0.15% of chlorine dioxide, 0.01-0.02% of phytic acid, 0.01-0.3% of citric acid and the balance of water. The invention has the advantages that: the moisture of product is less than or equal to 5%, the content of sulfur dioxide is less than or equal to 30 mg / kg. In the processing step, the invention does not use sulphite to protect the colour, so the invention has low content of sulfur dioxide and is healthy to human body. The appearance of the product is white or milky white and has special taste of dehydrated agaricus bisporus; the product can be directly eaten or used as seasoning to be added into instant food, such as instant noodles, instant bean vermicelli, instant soup and the like.

Description

technical field [0001] The invention relates to the technical field of food processing, and more specifically relates to a processing method of Agaricus bisporus. Background technique [0002] Agaricus bisporus has high nutritional value, its protein content is 35%-38%, and its nutritional value is 4-12 times that of vegetables and fruits. Especially favored by the international market, Agaricus bisporus is best eaten fresh and should not be stored for a long time. To develop Agaricus bisporus in a large area, deep processing must be considered, otherwise the product will backlog and deteriorate. At present, Agaricus bisporus is usually dehydrated. The processing method is roughly as follows: [0003] 1. Material selection: Fresh Agaricus bisporus is used as raw material; [0004] 2. Cleaning: Clean the fresh Agaricus bisporus raw materials in time. The specific method is: put the fresh Agaricus bisporus into tap water to wash away dirt and other dirt. Do not hit the Agari...

AI Technical Summary

Problems solved by technology

The Agaricus bisporus slices processed by the above processing method are difficult to control the moisture content of the final product, often making the product moisture ≥ 5%, the product appearance is brown or gray, and the taste is not good. Sulfite is used as a color-protecting agent, resulting in the final sulfur dioxide content of the product reaching more than 500mg / kg, which is harmful to human health
