The experimental process and experimental results of the beer fresh-keeping enzyme are analyzed as follows:
the method comprises the following experimental steps:
1. the addition amount of the beer fresh-keeping enzyme is as follows:
TABLE 1 enzyme addition and indication
2. Preparation of beer fresh-keeping enzyme sample
5.9267 g of beer preserving enzyme is weighed to 100 ml, and 59.267 mg/ml of beer preserving enzyme solution is obtained.
0.0456 g of glucose was weighed out and dissolved, and the volume was adjusted to 50 ml to obtain a glucose solution of 0.912 mg/ml.
3. Beer fresh-keeping enzyme experimental method
Beer freshness enzyme experiments were performed on-site at the first package line at 8 months, 2 days, 10:30 in 2016. The production varieties on the first-line date are as follows: 595ml of 9 ℃ wheat is bottled (common beer).
The washed empty bottles were sampled and added to the test samples in the amounts shown in Table 1. Namely, 0.2 ml and 0.4 ml (the beer fresh-keeping enzyme solution with the concentration of 59.267 mg/ml) are respectively measured and put in a marked empty bottle for filling and sterilization. Thus obtaining a sample 1 and a sample 2.
0.2 ml (59.267 mg/ml beer preserving enzyme solution) and 0.2 ml (0.912 mg/ml glucose solution) are measured and put into the marked empty bottle, and filling and sterilization are carried out, thus obtaining the sample 3.
Second, experimental results
1. Dissolved oxygen detection (detection time: 2016 (8/2/8/15/30 pm, fresh liquor sample))
TABLE 1
From total oxygen analysis, the dissolved oxygen is slightly reduced after the beer preservative is added. But the reduction is not so great, mainly due to the low dissolved oxygen of the wine blank itself. The anti-aging of the wine body needs to be verified by a strengthening experiment. (strengthening experiment method: after preserving heat at 60 ℃ for 48 hours, cooling to 3 ℃, and after preserving heat at 20 ℃ for 30 minutes, carrying out detection analysis, wherein the process is called a period.).
2. Detection data and evaluation results after one period of reinforcement experiment
TABLE 2 dissolved oxygen and physicochemical index test results (2016 year 8 month 8 day test, strengthening one period wine sample)
Table 3 detailed results of the weathering:
by combining the analysis of tables 2 and 3, 1) and the reduction of the liquid phase oxygen of the wine body by 0.6ppb and 0.5ppb respectively, 17.64 percent and 14.71 percent respectively after 20ppm and 40ppm of beer fresh-keeping enzyme are added; the total oxygen is respectively reduced by 9ppb and 8ppb by 36.0 percent and 32.0 percent. And the total oxygen content of 20ppm of beer fresh-keeping enzyme and 0.3ppm of glucose is reduced by 5ppb and 20.0%. 2) After the beer fresh-keeping enzyme is added, the detection of the relevant beer physical and chemical indexes has no obvious change. 3) From the aging degree analysis, the best effect is obtained by adding 20ppm of beer preserving enzyme, and the effect is the second best by adding 20ppm of beer preserving enzyme and 0.3ppm of glucose. Therefore, it was decided to conduct production experiments with 20ppm of beer freshness enzyme added.
Third, beer fresh-keeping enzyme experiment is carried out by abnormal filling technology
The sake (595 ml at 9 ° state banquet) is taken from the bag in one line and then opened at 2016 (8 months and 3 days). 1. Respectively adding 0.2 ml and 0.4 ml (the beer fresh-keeping enzyme solution with the concentration of 59.267 mg/ml) to obtain a sample 1 and a sample 2 with the beer fresh-keeping enzyme concentrations of 20ppm and 40ppm respectively. Capping and sterilization are carried out after about 40 seconds. 2. Adding 0.2 ml (59.267 mg/ml beer preserving enzyme solution) and 0.2 ml (0.912 mg/ml glucose solution) to obtain 20ppm beer preserving enzyme and 0.3ppm glucose, and capping and sterilizing after about 40 seconds. 3. And (5) blanking the sample, opening the cover for 40 seconds, capping and sterilizing.
The detection indexes of the dissolved oxygen are as follows:
TABLE 4
From the above detection data, it can be seen that the liquid phase oxygen is greatly reduced. About 400ppb reduction. The beer fresh-keeping enzyme has an effective effect by mainly opening the cap and then pressing the cap, wherein the dissolved oxygen of the beer body is higher. The difference of gas phase oxygen is mainly caused by the error between uncovering and covering.
And (4) synthesizing the analysis of the experimental results, and performing a production experiment by adding 20ppm of beer fresh-keeping enzyme.
The beer filtration fresh-keeping enzyme adding step:
1. the beer fresh-keeping enzyme is prepared into solution with a certain concentration by using dilution water, and the concentration is generally controlled to be about 10%.
2. And starting the stirrer to stir so as to uniformly mix the beer fresh-keeping enzyme.
3. The carbon dioxide with the purity of more than or equal to 99.995 percent is used for protecting the beer fresh-keeping enzyme storage tank so as to reduce oxygen absorption of the beer fresh-keeping enzyme solution.
4. The beer fresh-keeping enzyme is uniformly added into the sake pipeline at a certain flow rate by using a variable frequency pump (namely a delivery pump) according to the flow rate of the sake, so that the sake is ensured to contain a certain amount of beer fresh-keeping enzyme.
The beer freshness enzyme was added in the above manner, and the amount of the addition was 20 ppm. Additive production experiments were performed. The results of the experiment were analyzed as follows:
TABLE 5 Change Table for testing TPO at different times
After the beer freshness-retaining enzyme is added, the TPO of the beer is obviously reduced along with the extension of the storage time. The finished beer added with 20ppm of fresh-keeping enzyme is evaluated after being placed for 9 months, the beer is slightly aged, and the detection results of the physical and chemical indexes of the rest beer are normal.
Through the research on the beer filtration and preservation process and the improvement on equipment, the appearance of the aging taste of the finished beer is effectively delayed, the original flavor of the beer is ensured, and the drinkability of the beer is improved.
The product form of the present invention is not limited to the embodiment of the present invention, and any person can properly change or modify the product form of the present invention without departing from the scope of the present invention.
