Embodiment 1

[0034] In this embodiment, red tassel sorghum is selected as the sample to be tested.

[0035] (1) Sorghum sample pretreatment

[0036] After removing impurities from the sorghum grains of the sample to be tested, 10 g of the sample to be tested was sampled by the quartering method, and further pulverized by a cyclone mill to pass through a 1 mm sieve. After fully mixing, take 5g of powder sample to measure the moisture content, then weigh 6-7mg of dry base sample into a special crucible for differential scanning calorimeter, add 14μL of ultrapure water, equilibrate at room temperature for 1h, and then use it to determine the gelatinization temperature.

[0037] (2) Determination of peak gelatinization temperature

[0038] The peak gelatinization temperature of the sample was determined by differential scanning calorimetry, and the specific parameters were:

[0039] Nitrogen was used as a protective gas with a flow rate of 50 mL / min; the initial temperature was 40°C and kept...

Abstract

The invention discloses a method for evaluating sorghum. The method comprises the following steps: measuring the peak gelatinization temperature of the sorghum; and when the peak gelatinization temperature of the sorghum falls into the peak gelatinization temperature value reference range, judging that the sorghum has at least one quality characteristic suitable for brewing. The gelatinization temperature is one of the thermal properties of a starchy sample and is influenced by the structural characteristics of starch, so that the gelatinization temperatures of different sorghum varieties are different due to the difference of starch particle structures. According to the method, based on the peak gelatinization temperature of sorghum, the wine brewing applicability of the sorghum variety is comprehensively evaluated through the peak gelatinization temperature discrimination index, so that a novel wine brewing sorghum variety evaluation method is provided.

Description

technical field [0001] The invention relates to the field of crop analysis, in particular to a method for evaluating sorghum by peak gelatinization temperature. Background technique [0002] Sorghum is an important cultivated crop in my country, and it is also the main brewing raw material for most famous wineries in the country. However, how to judge the brewing quality of sorghum is an important problem that wineries need to face when purchasing raw materials. The quality of raw materials affects the quality and quality of the final liquor product. In recent years, with the expansion of the Maotai-flavored wine industry, the demand for sorghum raw materials has been increasing. Maotai-flavored wine represented by Moutai needs to use sorghum varieties with the quality characteristics of "small grains, thick skin, red color, resistance to cooking, and high glutinousness" as raw materials for winemaking, so that it can be suitable for multiple rounds of cooking and fermentat...
