Problems solved by technology

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 water, which will easily deteriorate the taste and flavor, and the packaging will shrink and affect the appearance. However, adding food preservatives to preserve the quality, and because of the excessive use of preservatives, does not meet the national standards. Or become the focus of food safety reports

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...
