Problems solved by technology

However, Gastrodia elata products currently exist mostly in the form of primary processing products such as Gastrodia elata powder, Gastrodia elata capsules, Gastrodia elata decoction pieces, Gastrodia elata medicinal food, preserved Gastrodia elata fruit, Gastrodia elata snow flakes, Gastrodia elata candied fruit, Gastrodia elata health wine, etc. The degree of intensive processing is low, and the added value of products is not high. short, which limits the sustainable and stable development of Gastrodia elata industry

Embodiment 1

[0025] A preparation method of Gastrodia elata oral liquid fermented by Lactobacillus plantarum, the specific steps are as follows:

[0026] (1) Take Gastrodia elata powder as raw material, add sterile water according to the mass volume ratio (g / mL) 1:11 and make it fully dissolved; add compound enzyme according to the mass volume ratio (mg / mL) of 0.4%; then use lemon Adjust the pH value to 4.0 with acid, and enzymatically hydrolyze Gastrodia elata at 50°C for 180 minutes to obtain the enzymatic solution of Gastrodia elata, which is used as the fermentation base solution; the compound enzyme is a mixture of pectinase, cellulase, tannase and α-amylase in equal proportions, and the enzyme activity 30,000 U / g, 100,000 U / g, 300 U / g, 40,000 U / g respectively;

[0027] (2) Cool the fermentation base liquid described in step (1) to 30-40°C, filter it with a 100-mesh stainless steel mesh, add sucrose to the filtrate at a mass-to-volume ratio (g / mL) of 9%; After homogenizing for 3-5 mi...

Abstract

The invention discloses a lactobacillus plantarum and a preparation method and application of a gastrodia elata oral liquid fermented by the lactobacillus plantarum, and belongs to the technical field of food. The gastrodia elata oral liquid is produced by performing enzymolysis on gastrodia elata by adopting four compound enzymes including pectinase, cellulase, tannase and alpha-amylase to obtain enzymatic hydrolysate, and inoculating lactobacillus plantarum STDA6 to ferment by taking the enzymatic hydrolysate as a fermentation substrate. The fermented gastrodia elata oral liquid disclosed by the invention integrates the probiotic functions of gastrodin and lactic acid bacteria, and has the health-care functions of improving sleep, promoting intestinal microecological balance and the like; the fermented gastrodia elata oral liquid prepared by the invention is uniform and bright in color, moderate in sour-sweet proportion, fine and soft, and uniform in tissue state; and the processing technology is simple, the process is controllable, the quality is guaranteed, and batch production is facilitated.

Description

technical field [0001] The invention relates to the field of food technology, and more specifically relates to a preparation method and application of a strain of Lactobacillus plantarum and its fermented Gastrodia elata oral liquid. Background technique [0002] Gastrodia elata is the dry tuber of the orchid plant Gastrodia elata Bl., which is a traditional Chinese medicinal material. It is pungent, warm and non-toxic. It is rich in gastrodin, vanillin, polysaccharides, amino acids and trace elements. "Shen Nong's Materia Medica" Gastrodia elata is the top grade, "long-term use can benefit energy, grow yin, be fat and healthy, lighten the body, and increase years"; "Records that Gastrodia elata "cures dizziness and headache due to wind deficiency", hence the name Dingfengcao"; Zhang Zhicong, a famous doctor in Qing Dynasty, praised Gastrodia elata as "the same merit as the five sesame seeds, more powerful than the five ginseng, and it is the top grade for immortals."
