Problems solved by technology

However, these chemicals will affect the natural flavor of bamboo shoots and are not easily accepted by the market.
[0006] In order to improve production efficiency, repeated sudden changes in the processing temperature during the production of quick-frozen bamboo shoots will easily damage the tissue structure and fiber structure of the bamboo shoots, so that the quick-frozen bamboo shoots will be soft and brittle after thawing, which will affect the taste.

Abstract

The invention relates to a method for producing quick-frozen bamboo shoots. The method comprises the following steps: taking fresh bamboo shoots as raw materials, pre-cooking, cleaning, sterilizing and freezing, thereby obtaining the quick-frozen bamboo shoots. At the pre-cooking phase, the fresh bamboo shoots are boiled out in boiling water, so on one hand, the bamboo shoots are not continuously lignified, and the crispness of the bamboo shoots is ensured; and on the other hand, microbes attached onto the fresh bamboo shoots can be killed, and pesticide residues can be effectively reduced. In the whole production process, the processing temperature change in each process is gentle, a great sudden temperature change link is not needed, and the crispness of the bamboo shoots is well maintained. Any chemical is not added in the whole production process, so that the product has original taste and flavor and is natural in taste. Therefore, the quick-frozen bamboo shoot produced by the method disclosed by the invention has inherent color, crispness, flavor and freshness of the bamboo shoots and is an ideal fresh bamboo shoot product which can be stored for a long time.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of quick-frozen bamboo shoots. Background technique [0002] Bamboo shoots are rich in dietary fiber, protein, carbohydrates, minerals and carotene, vitamins B1, B2, C, etc., and have the functions of clearing heat and reducing phlegm, nourishing qi and stomach, curing thirst, benefiting intestines, benefiting diaphragm and refreshing stomach, etc. Efficacy, as an excellent health vegetable, it is eaten by more and more people. [0003] Bamboo shoots are mainly eaten with fresh bamboo shoots, fermented bamboo shoots, dried bamboo shoots and boiled bamboo shoots. Bamboo shoots are prone to aging after mining. For this reason, the bamboo shoot products that can preserve for a long time such as fermented bamboo shoots, dried bamboo shoots and boiled bamboo shoots have been developed. However, this development has destroyed the color, flavor, crispness ...
