Research And Development Of Rapid Detection Device And Detection Method For Moisture Content Of Meat Based On Resistance Method

China's total consumption of fresh meat accounts for about one-third of the world's since 1990.With the improvement of the living standard of human,the diet structure of human has undergone unprecedented changes,and the proportion of fresh meat in the daily diet of Chinese people is also increasing.Therefore,the total consumption of fresh meat in China will further increase in the future.Therefore,while the total consumption and production of fresh meat are increasing,the quality problems of fresh meat also appear frequently,and the moisture content of meat is an important index to examine the quality of meat.The acid and alkali values of water in fresh meat are different due to different areas,different varieties,different killing time and other factors,which directly affect the raw meat in ionic quantity,caused that the moisture content of value each have differences by the resistance of the acquisition of fresh meat,and this is one of the effects of moisture content measurement process system error;Temperature also has a great influence on the accuracy of resistance measurement,which is another systematic error in moisture content measurement.If the PH and temperature of the sample are not compensated,the moisture content obtained by the resistance method will produce a serious mistake,which has a great impact for the storage and transportation of fresh meat.Therefore,it is an indispensable step to compensate and correct the corresponding parameters such as PH and temperature.Therefore,this paper designed a device to detect the moisture content offresh meat.The signal generator generates oscillating signals of specific frequency and amplitude,converts the size of meat moisture content into electrical signals for signal processing,and controls data acquisition,program control,data processing and other equipment through MCU.This paper introduces the theory and practice of equipment,hardware structure,software design,preliminary experiment and result data.As the PH correction of meat has not been completed at present,the equipment has not added the PH correction,so only theoretical experimental verification is carried out.
