Embodiment 1

[0036] A kind of preparation technology of green bamboo shoot dietary fiber bread, this technology comprises the following steps:

[0037] 1) Pretreatment of green bamboo shoots

[0038] Choose fresh bamboo shoots without insects as raw materials, peel off the bamboo shoot shell, cut off the hard bamboo roots and inedible parts, clean them, cut them into small pieces, heat the bamboo shoots in a microwave oven for about 10 minutes, and cook the bamboo shoots When softened and translucent, remove with a slotted spoon and cool to room temperature.

[0039] 2) Preparation of starter

[0040] Prepare the bamboo shoot slices and water obtained in step 1) with a mass ratio of 1:2, beat and filter to obtain bamboo shoot juice; add 3% of its weight skimmed milk powder and 2% of granulated sugar to the above bamboo shoot juice, stir evenly, and pack into a container Medium; sterilize by heating in a water bath for 15 minutes at a temperature of 90°C, and cool to room temperature to f...

Abstract

The invention discloses a preparation process for green bamboo shoot dietary fiber bread. The method comprises the following steps of: fermenting pretreated, pulped, prepared and sterilized green bamboo shoots by using lactic acid, wherein the lactic acid is formed through mixed cultivation of lactobacillus acidophilus and bifidobacterium adolescentis, the strain proportion is 1:1, the fermentation time is 20-24 hours, the cultivation temperature is 37-40 DEG C, and the inoculum size is 3-5 percent; and then drying bamboo shoot residue under vacuum, wherein the drying time is 22-35 hours and the drying temperature is 60-70 DEG C. Compared with the dietary fibers prepared by other fermentation processes, the extraction rate of the dietary fiber is increased, particularly the extraction rate of the soluble dietary fiber is increased, and the water holding capacity is improved. Vacuum drying is low-temperature drying, so that the water holding capacity and the expansibility of a final product are improved. 5-6 percent of dietary fiber is added into the bread flour to prepare the dietary fiber bread, so that the aging is effectively prevented, the softness and the looseness are improved, and the shelf life of the bread is prolonged.

Description

technical field [0001] The invention belongs to food processing technology, in particular to a processing technology of green bamboo shoot dietary fiber bread. Background technique [0002] Green bamboo is a subtropical high-quality cluster bamboo mainly used for shoots, and it is a famous high-quality cluster bamboo species for shoots in southern my country. Bamboo shoots are a special vegetable, and people in Lingnan list it as a top-notch summer vegetable and a treasure in dishes. The taste is fresh, refreshing, delicious, and rich in nutrition. It has always been known as the "No. 1 vegetarian food". And the green bamboo shoots are the treasures of bamboo shoots, famous and special products.
