Embodiment 1

[0040] A control method for safe storage of barley, comprising the following steps:

[0041] ① detecting the germination rate of barley: detecting the germination rate of barley for five days and the germination rate of the first day, the second day and the third day; the specific steps of the barley germination rate detection are:

[0042] (a) Put two pieces of filter paper with a diameter of 9cm into the bottom of the Petri dish, add 4ml of water to evenly wet the filter paper;

[0043] (b) Take 100 samples and put them on the filter paper, so that each grain is in good contact with the filter paper, and cover the petri dish;

[0044] (c) Put the petri dish into a plastic bag and seal it tightly to prevent water from evaporating, and germinate in a dark place at a room temperature of 18-20°C;

[0045] (d) Count the number of germinated barley grains after standing for 24h, 48h, 72h and 120h respectively, and obtain the germination rate of barley on the first day, the second d...

Embodiment 2

[0059] A control method for safe storage of barley, wherein the barley is Gamai Copeland and Omai Baudin, comprising the following steps:

[0060] ① detecting the germination rate of barley: detecting the germination rate of barley for five days and the germination rate of the first day, the second day and the third day; the specific steps of the barley germination rate detection are:

[0061] (a) Put two pieces of filter paper with a diameter of 9cm into the bottom of the petri dish, add 4ml of water to evenly wet the filter paper;

[0062] (b) Take 100 grain samples and put them on the filter paper, so that each wheat grain is in good contact with the filter paper, and cover the petri dish;

[0063] (c) Put the petri dish into a plastic bag and seal it tightly to prevent water from evaporating, and germinate in a dark place at a room temperature of 18-20°C;

[0064] (d) Count the number of germinated barley grains after standing for 24h, 48h, 72h and 120h respectively, and ...

Abstract

The invention discloses a control method for barley safe storage. The control method for the barley safe storage is characterized by comprising steps of: (1) detecting germination rates of the barley: detecting a five-day germination rate of the barley, and germination rates on first day, second day and third day; (2) computing a barley safe storage index (BSI) according to the detected germination rates of the barley; (3) judging storage risk of the batch of barley according to the five-day germination rate of the barley and BSI value obtained by computing; and (4) according to the judgment result of the step (3), performing proper treatment measure on the barley with the BSI value not less than 0.20. The control method for the barley safe storage provided by the invention puts forward the BSI; therefore, the forecast on change of the five-day germination rate of the stored barley is realized by the BSI value, and a control method for the barley safe storage is built based on a forecast result, thus filling a gap in the field of industry; and according to the control method for the barley safe storage, the quality and taste of beer can be ensured from source, thus being beneficial to accepting products by customers and further expansion of market.

Description

technical field [0001] The invention belongs to a grain storage method, and in particular relates to a control method for safe storage of barley used for brewing beer. Background technique [0002] Beer is made from barley malt made by germinating barley as the main raw material, which is brewed by saccharification, adding hops, and brewing yeast fermentation. It contains carbon dioxide, low alcohol concentration, and sparkling brewed wine. Generally speaking, the main purpose of barley germination is to activate and decompose to produce various hydrolytic enzymes, impart a unique malt aroma, and make the raw material indicators meet the standards of beer production. As an important raw material for beer production, the quality of barley has a crucial impact on the quality of beer, and the germination rate of barley is the most important indicator to test the quality of barley. [0003] The germination rate of barley refers to the percentage of the number of germinated test...
