Embodiment 1

[0025] The steps for preparing clarified hawthorn juice beverage are as follows:

[0026] (1) Raw material selection and cleaning: Choose 1000 kg of red, non-rotten, mature exposed hawthorn, and wash it with water.

[0027] (2) Precooking and beating: Add 2000kg of pure water to the hawthorn, heat and boil for 3 minutes, and beat while it is hot to obtain a slurry.

[0028] (3) Serum enzymatic hydrolysis: at a temperature of 45°C, add pectinase and cellulase to the slurry, stir well and keep it warm for 10 hours. After the reaction is complete, use a centrifuge to filter the enzymatic hydrolysis slurry. Remove unenzymolyzed cellulose and pericarp to obtain enzymolysis slurry; based on the volume of enzyme added per kilogram of hawthorn, the dosage of pectinase is 0.5ml / kg, and the dosage of cellulase is 0.2ml / kg.

[0029] (4) Methanol removal: using figure 1 The methanol removal device shown in the figure removes methanol in the enzymatic hydrolysis slurry by means of circul...

Embodiment 2

[0034] The steps for preparing clarified hawthorn juice beverage are as follows:

[0035] (1) Raw material selection and cleaning: Choose 1000 kg of red, non-rotten, mature exposed hawthorn, and wash it with water.

[0036] (2) Precooking and beating: Add 2000kg of pure water to the hawthorn, heat and boil for 4 minutes, and beat while it is hot to obtain a slurry.

[0037](3) Serum enzymatic hydrolysis: at a temperature of 48°C, add pectinase and cellulase to the slurry, stir well and then keep it warm for 9 hours. After the reaction is complete, use a centrifuge to filter the enzymatic hydrolysis slurry. Remove unenzymolyzed cellulose and pericarp to obtain enzymolysis slurry; based on the volume of enzyme added per kilogram of hawthorn, the dosage of pectinase is 0.6ml / kg, and the dosage of cellulase is 0.3ml / kg.

[0038] (4) Methanol removal: using figure 1 The methanol removal device shown in the figure removes methanol in the enzymatic hydrolysis slurry by means of cir...

Embodiment 3

[0043] The steps for preparing clarified hawthorn juice beverage are as follows:

[0044] (1) Raw material selection and cleaning: Choose 1000 kg of red, non-rotten, mature exposed hawthorn, and wash it with water.

[0045] (2) Precooking and beating: Add 2000kg of pure water to the hawthorn, heat and boil for 5 minutes, and beat while it is hot to obtain a slurry.

[0046] (3) Slurry enzymatic hydrolysis: at a temperature of 52°C, add pectinase and cellulase to the slurry, stir well and then keep it warm for 8 hours. After the reaction, the enzymatic hydrolysis slurry is then centrifugally filtered with a centrifuge. The unenzymolyzed cellulose and pericarp were removed to obtain an enzymolysis slurry; based on the volume of enzyme added per kilogram of hawthorn, the dosage of pectinase was 0.7ml / kg, and the dosage of cellulase was 0.4ml / kg.

[0047] (4) Methanol removal: using figure 1 The methanol removal device shown in the figure removes methanol in the enzymolysis slur...

Abstract

The invention discloses a method for preparing a clear hawthorn juice drink by enzymolysis of hawthorn. The method comprises the following steps: (1) selecting red, non-rotted and mature hawthorn and washing the hawthorn with water; (2) adding purified water into the hawthorn, heating and boiling for 3-5 minutes, pulping while a solution is hot, and preparing pulp; (3) adding pectinase and cellulase into the pulp, filtering after reaction, and preparing enzymatically hydrolyzed pulp; (4) removing methanol in the enzymatically hydrolyzed pulp with a circulating spray extraction method by utilizing a methanol removal device, filtering after methanol removal, and preparing clear hawthorn juice; (5) pumping the clear hawthorn juice into a resin acid reduction tank by using a pump at a room temperature for acid reduction, and preparing raw hawthorn juice; (6) precisely filtering the raw hawthorn juice, performing instant high-temperature sterilization, and preparing a pure hawthorn juice drink; or, taking the raw hawthorn juice as a basic material and preparing hawthorn juice drinks different in raw hawthorn juice content. The method is good in methanol removal effect and low in destruction loss of effective nutritional ingredients of the hawthorn, and the investment and operation costs and energy consumption of the methanol removal device are greatly reduced.

Description

technical field [0001] The invention relates to a method for preparing clarified hawthorn juice beverage through enzymatic hydrolysis of hawthorn. Background technique [0002] Hawthorn is a dual-purpose mountain fruit for medicine and food. It contains almost all the nutrients of the fruit. Its main components are: maslinic acid, flavonoids, vitamin C, 18 kinds of amino acids, etc., especially the high content of vitamin C, which is 17 times that of apples. 30 times higher than pear. Since hawthorn is a fruit with high pectin content, a large amount of methanol will be produced after enzymatic hydrolysis with pectinase. The methanol content after enzymatic hydrolysis is as high as 2000㎎ / L based on the hawthorn pulp of hawthorn and water 1:2. If this slurry is used to make it directly For hawthorn juice and hawthorn juice drinks, the methanol content greatly exceeds the standard, and methanol needs to be removed. At present, the use of traditional distillation towers to re...
