Problems solved by technology

[0008] At present, in the literature on the development of ginkgo products, there is no report on the application of probiotic fermentation to ginkgo (nut) beverages. Therefore, according to the characteristics of ginkgo nuts, a more suitable type of hydrolase and probiotics are selected. Combining food processing technology with modern enzymolysis and fermentation technologies to prepare ginkgo drinks with good taste and high nutritional value has important research significance and good market prospects

Embodiment 1

[0045]

[0046] 1) Pretreatment of Ginkgo biloba: Accurately weigh the Ginkgo biloba after shelling, add to boiling water, boil for 15 minutes, remove the endocarp and wash with water;

[0047] 2) Preparation of slurry: take the processed Ginkgo biloba according to the formula, add 5 times the volume of water, and use a refiner for coarse grinding. The coarse abrasive liquid is finely ground twice through a colloid mill to obtain slurry A. The measured viscosity is 265mpa .s (rotor No. 1, 6rpm, 25°C), the starch content is greater than 30.0g / L;

[0048] 3) Enzymolysis: Add α-amylase to slurry A, enzymolyze at 65°C for 60 minutes, then add liquid glucoamylase, enzymolyze at 60°C for 120 minutes, inactivate enzyme at 92°C for 8 minutes after enzymolysis, and obtain enzymolysis material B, measure Viscosity is 50mpa.s (No. 1 rotor, 6rpm, 25°C);

[0049] 4) Filtration: Enzymolysis material liquid B is firstly filtered through a 80-mesh sieve, and then finely filtered through a...

Embodiment 2

[0058] The liquid glucoamylase in the hydrolytic enzyme in Example 1 was removed, and the others were prepared in the same manner as in Example 1. The viscosity of slurry A was measured to be 268mpa.s (rotor No. 1, 6rpm, 25°C), and the starch content was greater than 30.0g / L; the viscosity of feed liquid B is 58mpa.s (No. 1 rotor, 6rpm, 25°C); the starch content in feed liquid C is less than 5.0g / L, the total sugar content is more than 30.0g / L, and the protein content is about 0.35g / 100ml.

Embodiment 3

[0060]

[0061] 1) Ginkgo pretreatment: accurately weigh the shelled ginkgo, add it to boiling water, boil for 10 minutes, remove the endocarp and wash it with water;

[0062] 2) Preparation of slurry: take the processed Ginkgo biloba according to the formula, add 6 times the volume of water, and use a refiner to perform coarse grinding, and the coarse abrasive liquid is finely ground twice through a colloid mill to obtain slurry A, and the measured viscosity is 213mpa .s (rotor No. 1, 6rpm, 25°C), the starch content is greater than 25.0g / L;

[0063] 3) Enzymolysis: Add α-amylase to slurry A, enzymolyze at 60°C for 60 minutes, then add liquid glucoamylase, enzymolyze at 62°C for 120 minutes, and inactivate enzyme at 90°C for 10 minutes after enzymolysis to obtain enzymolysis material B, measure Viscosity is 53mpa.s (No. 1 rotor, 6rpm, 25°C);

[0064] 4) Filtration: Enzymolysis feed solution B is firstly filtered through a 100-mesh sieve, and then finely filtered through a ...

Abstract

The invention discloses a gingko beverage and a preparation method thereof, belonging to the technical field of processing of food beverages, and providing a novel process for preparing a gingko beverage by using a modern biotechnology. According to the gingko beverage and the preparation method thereof, by adopting conventional processes of shelling, cooking for detoxicating, removing endopleura, colloid-milling, homogenizing and the like and a modern enzymolysis technology, or a preparation method further matched with an enzymolysis technology and a probiotic fermentation technology, on the basis of preserving organic nutrients and flavor of gingko, the problems of high viscosity and poor taste of the gingko beverage are solved; the prepared gingko beverage is cool and fine in taste, delicious in sour and sweetness, relatively excellent in palatability, and stable in tissues; nutritional ingredients are relatively preferably absorbed by a human body; meanwhile, the gingko beverage is rich in effective ingredients such as abundant ginkgetin and ginkgo terpene lactones, and has a relatively excellent health function.

Description

technical field [0001] The invention belongs to the technical field of food and beverage processing, and in particular relates to a ginkgo beverage and a preparation method thereof, in particular to a method for developing ginkgo beverage by adopting enzymatic hydrolysis technology or a combination of enzymatic hydrolysis technology and probiotic fermentation technology. Background technique [0002] Ginkgo biloba, also known as ginkgo, gongsun tree, duck foot tree, cattail leaf fan. Ginkgo contains a variety of nutritional elements. In addition to starch, protein, fat, and sugar, it also contains trace elements such as vitamin C, riboflavin, carotene, calcium, phosphorus, iron, potassium, and magnesium, as well as ginkgolic acid and ginkgophenol. , five-carbon polysaccharides and other ingredients, which have dietary and medical effects such as nourishing lung qi, curing cough and asthma, stopping turbidity, reducing stool, flattening wrinkles, protecting blood vessels, and...
