preparation example Construction

[0029] Two, a kind of preparation method of fruit wine clarifying agent, comprises the steps:

[0030] 1) Dissolve graphene oxide in ultrapure water according to the formula, and ultrasonically treat it for 1-4 hours to make it evenly dispersed in water;

[0031] 2) Add chitosan to the solution obtained in step 1) under the condition of high-speed stirring, and add acetic acid solution, and continue to stir for 1~4h;

[0032] 3) Ultrasonicate the chitosan / graphene oxide mixture obtained in step 2) for 30 minutes, add sodium alginate and glutaraldehyde, and stir for 1-4 hours;

[0033] 4) Put the chitosan / graphene oxide / sodium alginate mixed solution obtained in step 3) in a vacuum oven at 40~70°C for 10~14h to react;

[0034] 5) Freeze-dry the sample obtained in step 4) at -40~-70pa for 40~60h, wash 3 times with ethanol, wash 3 times with distilled water, then freeze-dry the sample at -40~-70pa for 40~60h, and finally get clarification agent, namely chitosan / graphene oxide / s...

Embodiment 4

[0035] Embodiment 4: adopt following method to prepare clarifying agent according to the prescription of embodiment 1, comprise the steps:

[0036] 1) Weigh 0.05g of graphene oxide and dissolve it in 50 mL of ultrapure water, and ultrasonically treat it for 2 hours to make it evenly dispersed in the water;

[0037] 2) Add 0.4g of chitosan and 0.5mL of acetic acid solution to the solution obtained in step 1) under high-speed stirring, and continue to stir for 2 hours;

[0038] 3) Ultrasonicate the chitosan / graphene oxide mixture obtained in step 2) for 30 min, add 0.4 g of sodium alginate and 0.5 mL of glutaraldehyde, and stir for 2 h;

[0039] 4) Put the chitosan / graphene oxide / sodium alginate mixed solution obtained in step 3) in a vacuum oven at 50°C for 12 hours to react;

[0040] 5) The material obtained in step 4) was freeze-dried at -50pa for 48h, washed with ethanol for 3 times and distilled water for 3 times, and the sample was freeze-dried at -50pa for 48h, and final...

Embodiment 5

[0050] Example 5: Take 30 mL of peach wine in a 50 mL centrifuge tube, adjust the pH to 4.0 by adding sodium hydroxide solution or citric acid solution, and add the clarifying agent prepared in Example 4 in an amount of 0.54 mg / mL After mixing, the mixture was allowed to stand for 65 minutes at a temperature of 41° C., and then centrifuged and filtered to obtain clarified fruit wine. After the above process, the turbidity value of the peach wine was detected by a desktop turbidimeter, and the turbidity value of the peach wine was 1.624NTU.

[0051] The main difference between Embodiments 6-8 and Embodiment 5 lies in the difference in relevant proportion parameters, see Table 1 for details, and other operations are the same.

Abstract

The invention discloses a fruit wine clarifying agent and a preparation method thereof. The fruit wine clarifying agent consists of 0.01-0.05 g of graphene oxide, 0.4-0.6 g of chitosan, 0.4-0.6 g of sodium alginate, 0.3-0.6 mL of acetic acid solution, Dialdehyde 0.5~1.0mL; ultrapure water 50mL as solvent. The present invention utilizes the composite structure formed by chitosan, graphene oxide and sodium alginate, which has a good adsorption effect on substances that are prone to complex precipitation in fruit wine, and makes the wine body clear and shiny; effectively adsorbs protein, Substances such as metal ions have a good clarification effect and avoid turbidity. At the same time, it can effectively improve the stability of the fruit wine, so that the fruit wine will not be turbid during long-term storage, and the shelf life of the fruit wine is extended.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a fruit wine clarifying agent and a preparation method thereof. Background technique [0002] Fruit wine is an alcoholic beverage fermented from fresh fruit. It has low alcohol content and retains the original sugars, amino acids and minerals of the fruit. Fruit wine is rich in nutrition, pectin, tannin, protein, organic acid, metal ions and other substances in the wine body are easy to form complexes and precipitate out under the change of external conditions. Therefore, in the fruit wine production process, it is necessary to adopt a clarification process to handle it. However, most of the existing clarifiers have low wine body clarity, short validity period, complex components, and are prone to damage the nutritional components of fruit wine. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present ...
