Example Embodiment

[0011] The fruit hardness tester (compactness tester) is used to determine the degree of fruit ripeness, real-time control of picking and processing time, storage and transportation, etc., and is widely used in fruit tree production and processing. In our long-term sweet potato scientific research experiments, we have found that the dry matter content of potato chunks is closely related to the firmness (hardness) of the potato meat. Taking the hardness of the potato meat as the independent variable (x) and the dry matter rate of the potato chunks as the dependent variable (y), the regression equation is obtained: y=2.553x-2.650. After the significance test of the regression relationship, there is an extreme between the two Significant regression relationship (P<0.01), you can use the regression equation to estimate the corresponding dry matter rate of potato chunks from the hardness value of the potato meat. Therefore, under laboratory conditions, a fruit hardness tester is use...

Abstract

The invention discloses a simple method for measuring and calculating potato block dry matter rate and belongs to a determination method of tuber crop quality index. Hardness of potato pulp is used as an independent variable x, the potato block dry matter rate servers as a dependent variable y, x and y are substituted in a regression equation: y=2.553x-2.650, and the corresponding potato block dry matter rate (y) is figured out. A specific operation method includes: using a fruit hardness meter as a potato pulp hardness measuring tool; selecting potato blocks of moderate sizes; beveling the potato blocks from the middles; selecting a plurality of evenly-distributed measuring points on each oblique section; using the fruit hardness meter for measuring potato pulp hardness of each measuring point; and figuring out average valve x of potato pulp hardness of all measuring points of two oblique sections, substituting in the regression equation, and figuring out the corresponding potato block dry matter rate y. The simple method for measuring and calculating the potato block dry matter rate has the advantages of being simple in operation method, rapid, time-saving, energy-saving and safe. The regression equation is simple and easy to figure out. The simple method is particularly suitable for sweet potato planting farmers who have not high requirements on accuracy of the potato block dry matter rate and sweet potato starch processing enterprises.

Description

Technical field [0001] The invention relates to a simple method for measuring and calculating the dry content rate of potato pieces, which belongs to the method for measuring quality indexes of potato crops in production and processing. It is especially suitable for professional sweet potato planters and sweet potato starch processing enterprises that do not have high requirements on the accuracy of potato block dry matter rate. Background technique [0002] Sweet potato is an important food, feed and industrial raw material crop in my country, and its cultivation area and total output both rank first in the world. In recent years, sweet potato has attracted worldwide attention as an important new energy crop. As a crop with the highest dry matter yield per unit area, the dry matter content (dry matter rate) of sweet potato has also become a very important indicator for judging its quality. [0003] The conventional method for measuring the dry content of sweet potatoes is...
