Example Embodiment

[0018] Example one:

[0019] 1. Cleaning treatment: Clean lotus roots with consistent maturity, no deterioration or damage, and peel and remove lotus joints with a stainless steel knife.

[0020] 2. Color protection and warm water treatment: Soak the peeled lotus root section with color protection solution for 30 minutes and then wash it in warm water at 80°C for 2 minutes.

[0021] Among them, the color protection liquid is composed of water, tea polyphenols and NaCl. The mixing mass ratio of water, tea polyphenols and NaCl is 100:0.01:1. After water, tea polyphenols and NaCl are mixed, it is adjusted with citric acid. p H value to 2.5; solid-liquid ratio 1:5 when the color protection solution is soaked.

[0022] 3. Embrittlement treatment: Take the lotus root section after washing with warm water and soak it in the soaking solution with a solid-liquid ratio of 1:3, soaking time is 10 minutes.

[0023] Among them, the soaking liquid consists of water, CaCl 2 And citric acid, water, CaC...

Abstract

The invention relates to a processing method of an irradiation quality-guaranteed glutinous rice lotus root, and relates to the field of food processing and irradiation quality-guaranteed technologies. The processing method comprises the following steps: after cleaning a peeled and lotus rhizome knot-removed lotus root segment, steeping the lotus root segment after color-protecting and warm water processing into a CaCl2-containing soak solution, then adding glutinous rice containing sodium alginate tech grade to steam, and carrying out candying, sealed packaging and irradiation quality guarantee. A prepared product is moderately crisp, nice in glutinous sweet and long in quality-guaranteed period.

Description

technical field [0001] The invention relates to the technical field of food processing and radiation quality preservation, in particular to the technical field of aquatic vegetable product processing and radiation quality preservation. Background technique [0002] Lotus root is a perennial aquatic plant of Nymphaeaceae. It is eaten with fat and tender rhizomes. It is a very important aquatic vegetable in my country. It has high nutritional value and medicinal value. Glutinous rice lotus root is one of the traditional Chinese lotus root products. , Shanghai, Anhui and other places are especially popular and deeply loved by consumers. For a long time, the production and processing methods of glutinous rice lotus are mainly based on traditional techniques, which are prone to browning during processing and storage, and will gradually age and harden during storage. To prolong the shelf life, heat sterilization is often used. The glutinous rice will age, become thinner and seep w...
