Secondary fermentation and production method of rehydration flexible package dried bamboo shoot

Abstract

The invention discloses a secondary fermentation and production method of rehydration flexible package dried bamboo shoot, relating to the production method of dried bamboo shoot. The secondary fermentation and production method comprises the following working procedures for the dried bamboo shoot: adsorbing water, softening, slitting, boiling with water for swelling, rinsing to remove acid water, and packaging the bamboo product in vacuum. The secondary fermentation and production method is characterized in that: 1) secondary fermentation is carried out after rinsing to remove acid water, Lactobacillus acidophilus is added into the flaky and strip bamboo body processed in the previous working procedure for secondary pure breed fermentation at the fermentation inoculum size amount of 1.2-1.8%, lactic acid bacteria density of 2.9-3.5%, solid-to-liquid ratio of 2-4 and fermentation time of 13-18%; meanwhile, the pH value of the fermented bamboo body is controlled to be 3.7-4.6; and 2) the working procedure of rinsing is carried out after secondary fermentation, and the working procedure of packaging in vacuum is carried out. The invention has the advantages of solving the technical problems of poor lactic acid bacteria flavour, high coarse fibre content, low tenderness and the like caused by the method of once fermentation. The bamboo acidity is controlled to be that the pH is 3.7-4.6, coarse fibre content is controlled to be within 3.5%, and the tenderness, the tough-brittle taste and the chewing taste of the bamboo body can be improved.

Description

Technical field: [0001] The invention relates to a method for producing dried bamboo shoots, in particular to a method for producing instant dried bamboo shoots. Background technique: [0002] At present, the steps of traditional dried bamboo shoots before eating are: first soak them in water for 1 to 2 days, so that the dried bamboo shoots can absorb water and soften, and then can be cut into slices, filaments or strips as required, then boiled in boiling water for 20 to 30 minutes, and then soaked After a day or so, it can be cooked and eaten after rinsing and removing the acid water (it is very inconvenient to eat), or after rinsing and removing the acid water, it can be drained, weighed, bagged, vacuum sealed, sterilized, cooled, dried, inspected, and boxed. , The dried bamboo shoots can be made into rehydrated flexible packaging products, which can be cooked and eaten after opening the bag. You can also add seasonings after draining to make ready-to-eat soft-package dr...

Problems solved by technology

Although this fresh bamboo shoot product solves the process of eating without soaking and softening, its taste is different from that of dried bamboo shoots and lacks the flavor of dried bamboo shoots
