Description

A portable detection device for poultry egg freshness based on weight loss rate

technical field

The utility model relates to the detection of weight loss rate, computer and non-destructive detection technology of agricultural products, in particular to a portable detection device for the freshness of poultry eggs based on the weight loss rate.

Background technique

Poultry eggs are rich in a large number of nutritional elements and are deeply loved by consumers. Moreover, my country is a big country in the production and consumption of poultry eggs, and the total output of poultry eggs accounts for more than 40% of the total output of poultry eggs in the world.

The freshness of poultry eggs is an important indicator to measure the protein of poultry eggs. At present, the detection of the freshness of most poultry eggs relies on manual methods, and the detection efficiency and accuracy are not high.

Jiang Song, Qi Hong, etc. studied the relationship between the geometric size of poultry eggs and their volume and quality. The results show that the geometric size and mass of poultry eggs are normally distributed; the conclusion is that the volume of poultry eggs can be estimated by estimating the volume of standard ellipsoid. The mass of poultry eggs can be estimated by volume, and the correlation between the mass of poultry eggs and the estimated volume of poultry eggs is better than that of ternary and univariate linear regression with long diameter, short diameter, egg shape index, ellipse area at the long diameter of poultry eggs. 【Jiang Song, Qi Hong, Wang Guojiang, Jiang Xiaofeng, Analysis and experiment of basic characteristic parameters of poultry eggs [J]. Journal of Agricultural Machinery, 2012, 43(4)]. Yu Bin and Wang Xibo studied the changes in the weight loss rate of poultry eggs during storage. As the storage time continued to prolong, the quality of poultry eggs continued to decline. The weight loss rate and the pH of the whole egg were positively correlated with the storage time. The storage time is negatively correlated, and its changing law can be characterized by zero-order and first-order reaction kinetic equations, respectively. [Yu Bin, Wang Xibo, Study on the Correlation Between Storage Conditions and Poultry Egg Quality[J]. Food Science and Technology, 2012,37(6)].
