Problems solved by technology

[0009] As can be seen from the above-mentioned documents, the currently known methods for drying bamboo shoots include: (1) adopting the hot air drying method, although the yield and efficiency can be greatly improved, but due to the high temperature, the dried bamboo shoots often suffer from browning, Redness, and the quality of the obtained product is poor after rehydration; (2) After the bamboo shoots are color-protected, they are blanched for color protection, infiltration treatment, drying and other processes. The processing technology is complicated and the processing time is long

Embodiment 1

[0030] (1) Pick fresh bamboo shoots and peel off the leaves, put them in a roller washing machine, and wash them with water to remove soil and impurities;

[0031] (2) Put the cleaned bamboo shoots into the slicer, and cut the bamboo shoots horizontally into pieces;

[0032] (3) Put the bamboo shoots into the color protection solution immediately after slicing the bamboo shoots, and pick them up immediately after the bamboo shoots are completely immersed. The composition and mass percentage of the color protection solution are: tea polyphenols 5%, erythorbic acid 4%, phytic acid 2% and butyl hydroxyanisole 2%, the balance is purified water;

[0033] (4) Put the bamboo shoots into the dryer for the first drying. The drying temperature is 70℃ and the time is 17 minutes. After the first drying is completed, immediately spread the bamboo shoots evenly on a clean flat ground. Dry the bamboo shoots to dissipate hot steam and cool them as soon as possible. The drying time is 60 minutes; pu...

Abstract

The invention discloses a processing method of dried bamboo shoot slices, which includes cleaning, slicing, color protection, drying, packaging and sterilization, and is characterized in that fresh bamboo shoots are selected to peel off the sheath leaves, and then cut into bamboo shoot slices after cleaning. Put it into the color protection solution, and then carry out three times of hot air circulation drying and drying to obtain dried bamboo shoot slices, which are vacuum-packed and then sterilized. The processing method of the dried bamboo shoot slices of the invention has the characteristics of simple processing, unchanged color of the dried bamboo shoot slices, long storage time, good quality of the bamboo shoot slices, and the like.

Description

Technical field [0001] The invention relates to the processing field of agricultural and sideline products, in particular to a method for processing dried bamboo shoots. Background technique [0002] Bamboo shoots have been regarded as "treasures in dishes" in China since ancient times. Bamboo shoots are rich in protein, amino acids, fats, sugars, calcium, phosphorus, iron, carotene, vitamins B1, B2, and C. The content of multivitamins and carotene is more than twice as high as that of Chinese cabbage; and the protein of bamboo shoots is superior, lysine, tryptophan, threonine, phenylalanine, which are necessary for human body, are also occupied in the process of protein metabolism. The important glutamic acid and cystine, which can maintain the protein configuration, have a certain content and are excellent health-care vegetables. [0003] Bamboo shoots are a traditional Chinese delicacy, with a crisp, fragrant taste and a long history of eating and cultivation. The "Book of Son...
