Problems solved by technology

In the past, the judgment of grape maturity mainly relied on the experience of personnel, who judged by the different properties of color, taste, peel, pulp and seeds, or measured the clear alcohol content by sugar refractometer, combined with the analysis of grape pulp and peel. Judging the maturity by means of tasting and other means, this method has relatively large individual differences, and is seriously affected by the variety and the experience level of the staff
There are also physical or chemical methods to extract phenolic substances in grapes in the laboratory, and the maturity is judged by the amount of phenolic substances extracted. This method requires sampling and destructive treatment of samples, and the experimental analysis is complicated and time-consuming. long

Embodiment 1

[0026] A grape maturity detection device, such as figure 1 As shown, the rubber bowl 1 is oval, has a certain elasticity, and has a volume of 1000cm 3 . A timing device 10 is arranged on the outer side of the rubber bowl. One side of the rubber bowl 1 has a hole for passing through the ear stalk of the grape ear, and the lower part is connected with the air cylinder 2. The air suction duct 3 of the air cylinder can be stretched and can penetrate deep into the rubber bowl 1 and closely adhere to the grape ear for inhalation. The air outlet duct 4 of the air cylinder is connected The gas chamber 5 transports the gas inhaled in the gas cylinder to the gas chamber 5. The gas chamber 5 is a cube of 20cm×20cm×20cm. There is an ultraviolet light source 6 and a detector 7 on the upper part of the gas chamber 5. The upper and lower parts of the gas chamber 5 respectively have A reflector 8 reflects the light of the light source 10 times to increase the optical path of the light in th...

Embodiment 2

[0032] The method of the present embodiment is used for measuring the ripeness of wine grapes, thereby judging the optimal picking period of grapes. The grapes detected in this embodiment are the grape ears on the vine. The whole ear is buckled in the rubber bowl 1, and the root of the ear comes out through the opening on one side of the rubber bowl 1, so it is not necessary to remove the ear from the vine. can be detected directly.

[0033] The grape ear is isolated from the external environment, and the timing device is set for 30 minutes. At this time, the timing device 10 displays a red light. After 30 minutes, the timing is completed, and the green light is on, which means that the next step can be performed. The operator empties the air in the air cylinder 2, and then deeps the air suction duct 3 of the air cylinder 2 into the rubber bowl 1 until it reaches the stem of the grape ear, and then pulls out the piston of the air cylinder 2 to inhale the air in the rubber bowl...

Abstract

The invention relates to a device for testing a food by the aid of a testing and analyzing gas and application thereof. The invention provides a detection device of ripeness degree of grapes which comprises an isolation device of grape cluster surrounding air, an air suction device, an air chamber and a signal acquisition and analysis system, wherein the isolation device is connected to the air chamber through the air suction device; and the signal acquisition and analysis system comprises a detector located in the air chamber. The device provided by the invention can realize no-damage detection of grapes without experiences of personnel, so that the picking time can be judged; and the method provided by the invention can realize rapid measurement of the ripeness degree of the grapes without sampling treatment and chemical analysis in any type, so that disadvantages in the prior art are overcome.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a device for measuring food by means of measuring and analyzing gas and its application. Background technique [0002] Ethylene gas plays a very important role in the ripening process of the fruit, which can initiate and promote the emergence of peak respiration. Grape ears will release ethylene gas during respiration, and the rate of ethylene release from fruit stems and ear stems is much higher than that of fruit grains, and There will be a peak of respiration, causing the grapes to shatter. In the past, the judgment of grape maturity mainly relied on the experience of personnel, who judged by the different properties of color, taste, peel, pulp and seeds, or measured the clear alcohol content by sugar refractometer, combined with the analysis of grape pulp and peel. Judging the maturity by means of tasting and other means, this method has relatively large individual dif...
