Embodiment 1

[0060] Example 1 One of the preparations of edible carrier immobilized yeast

[0061] Carry out the following operations on the aseptic operating table, take 1.0g of Angel active dry yeast, activate it with 50ml of 2% sucrose solution at 30°C for 30min to obtain yeast liquid, add appropriate amount of yeast liquid into several conical flasks, Then add high-temperature sterilized 2% sucrose solution, dry-wash the cut jujubes, dry them as a carrier, and make the carrier immersed in the yeast liquid to obtain immobilized yeast. The size of dried jujube is 0.5cm×0.5cm.

Embodiment 2

[0062] Example 2 The second preparation of edible carrier immobilized yeast

[0063] Carry out the following operations on a sterile operating table, take 0.5g of Angel active dry yeast, activate it with 20ml 1% sucrose solution at 20°C for 40min to obtain yeast liquid, add appropriate amount of yeast liquid to several conical flasks, Then add high-temperature sterilized 1% sucrose solution, wash the cut bagasse, and dry it as a carrier, so that the carrier is immersed in the yeast liquid to obtain immobilized yeast. The dimensions of bagasse are small pieces with lengths of 1 cm and 2 cm.

Embodiment 3

[0064] Example 3 The third preparation of edible carrier immobilized yeast

[0065] Carry out the following operations on a sterile operating table: Take 2g of Angel active dry yeast, activate it with 100ml of 3% sucrose solution at 40°C for 10 minutes to obtain yeast liquid, add appropriate amount of yeast liquid to several Erlenmeyer flasks, and then Adding high-temperature sterilized 3% sucrose solution, washing the cut dried red dates and bagasse, drying them as carriers, and immersing the carriers in the yeast liquid to obtain immobilized yeast. The size of dried jujube is 0.5cm×0.5cm. The dimensions of bagasse are small pieces with lengths of 1 cm and 2 cm.

Abstract

The invention discloses a preparation method of an edible carrier immobilized yeast. The preparation method comprises the following steps of weighting 0.5-2g of angel active dry yeast, activating at the temperature of 20-40 DEG C for 10-40min by using 20-100ml of 1-3% sucrose solution to obtain a yeast solution, respectively adding a proper amount of yeast solution into a triangular flask, then, adding 1-3% high temperature sterilized sucrose solution, cleaning the chopped dried red date and / or bagasse, drying, and immersing the dried red date and / or bagasse as a carrier into the yeast solution to obtain the immobilized yeast, wherein all the operations are carried out on an aseptic operation platform. The invention also discloses the edible carrier immobilized yeast, a low-alcohol blueberry wine and a preparation method thereof. The yeast is treated by using different edible immobilized carriers, then, the low-alcohol blueberry wine is brewed, and the optimal immobilized carrier and the optimal fermentation condition are obtained, thus a batch of excellent low-alcohol blueberry wines are brewed under optimal conditions.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to an edible carrier-immobilized yeast and its preparation method and application. Background technique [0002] Blueberry is known as the "Queen of Fruits" and "The Fruit of Color Contact". Because of its high health value, it is popular all over the world. It is one of the five healthy fruits recommended by the World Food and Agriculture Organization. Blueberry is a fruit pulp with very high nutritional value, which is rich in vitamins, proteins, minerals and other nutrients, among which the unique and precious anthocyanin pigments in blueberries. The proportion of all fruits is very high, and blueberries are rich in protein, dietary fiber, fat, vitamins and other nutrients. Blueberries are also rich in trace mineral elements such as calcium, iron, phosphorus, and zinc, and the ratio of these mineral elements is significantly higher than that of other fruits. [0003] The very ...
