[0036] S1: Take ginger, wash it, crush it until it passes through a 20-mesh sieve, and prepare ginger powder;

[0037] S2: Ginger powder was extracted with supercritical fluid under the conditions of 30°C and 10MPa for 0.5h to prepare ginger extract and filter residue for later use;

[0038] S3: mix the ginger extract prepared in step S2 with honey and brown sugar in a weight ratio of 1:3.1:4.7 to obtain ginger crystals;

[0039] S4: add water to the filter residue prepared in step S2, soak for 3 hours at 25°C, and stir for 1 hour at a speed of 300r / min;

[0040] S5: Settling naturally for 8 hours, the obtained supernatant was spray-dried, the hot air inlet temperature was 230°C, and the exhaust air outlet temperature was 110°C.

[0041] The feed liquid after the natural sedimentation needs to be filtered to obtain the filter residue, and the filter residue is add...

Embodiment 2

[0044] S1: Take ginger, wash it, crush it until it passes through a 120-mesh sieve, and prepare ginger powder;

[0045] S2: Ginger powder was subjected to supercritical fluid extraction for 5 hours under the conditions of 80°C and 50 MPa to prepare ginger extract and filter residue for later use;

[0046] S3: mix the ginger extract prepared in step S2 with honey and brown sugar in a weight ratio of 1:5.5:6.8 to obtain ginger crystals;

[0047] S4: add water to the filter residue prepared in step S2, soak for 5 hours at a temperature of 35° C., and stir for 2 hours at a speed of 500 r / min;

[0048] S5: Settling naturally for 12 hours, the obtained supernatant was spray-dried, the hot air inlet temperature was 330°C, and the exhaust air outlet temperature was 170°C.

[0049] The feed liquid after the natural sedimentation needs to be filtered to obtain the filter residue, and the filter residue is added with water, the ratio of material to liquid is 1:7-9, using 0.02% α-amylase...

Embodiment 3

[0052] S1: Take ginger, wash it, crush it until it passes through a 40-mesh sieve, and prepare ginger powder;

[0053] S2: Ginger powder was subjected to supercritical fluid extraction at 45°C and 20 MPa for 2 hours to prepare ginger extract and filter residue for later use;

[0054] S3: mix the ginger extract prepared in step S2 with honey and brown sugar in a weight ratio of 1:3.1:4.7 to obtain ginger crystals;

[0055] S4: add water to the filter residue obtained in step S2, soak at 25°C for 3.5 hours, and stir at 300 r / min for 1.5 hours;

[0056] S5: Settling naturally for 8 hours, the obtained supernatant was spray-dried, the hot air inlet temperature was 240°C, and the exhaust air outlet temperature was 120°C.

[0057] The feed liquid after the natural sedimentation needs to be filtered to obtain the filter residue, and the filter residue is added with water, the ratio of material to liquid is 1:7-9, using 0.02% α-amylase, 0.06% β-amylase, 0.03% pectinase, Enzymolysis at...

Abstract

The invention relates to a method for jointly preparing ginger tea and ginger starch, the method comprises washing, smashing and sieving, supercritical extraction, sedimentation, filtration, spray drying, and the like, and the method simultaneously prepares ginger extract and the ginger starch. The ginger extract can be prepared into the ginger tea, the extraction rate of the ginger starch can reach 40.5%, the production efficiency is improved, the production time cost is shortened, and the production cost is reduced; ginger residue can be reused in the preparation of the ginger tea for preparation of the ginger starch, the bioavailability of the ginger residue is increased, environment pollution due to ginger residue discharge can be reduced, the problems of the environment pollution dueto the ginger residue discharge and waste residue bioavailability can be solved, the problems of post-treatment of ginger tea production waste and environmental pollution due to incomplete treatment can be solved.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a method for jointly preparing ginger tea and ginger starch. Background technique [0002] The preparation process of ginger tea is pulverization, extraction, and uniform mixing with ingredients to make ginger tea. Ginger dregs that have extracted active ingredients such as ginger oil are the main waste. These ginger dregs can also contain a large amount of ginger starch and fiber. The high utilization value material such as element, and ginger slag is generally all used as fertilizer or feed, has reduced the bioavailability of ginger slag. [0003] Ginger starch is rich in various amino acids and trace elements, has high nutritional value, and has a wide range of uses in food and industry. The extracted starch has been successfully developed into vermicelli, cold noodle, jelly and other foods. Ginger cellulose is a good raw material for the production of edible f...
