3 Terminology
3.1 Fruit Shape
The main shapes are nearly round, oval, oblate, elliptical and flat. 3.2 Deformed Fruit
Fruit with abnormal obvious protrusions or depressions and missing fruits. 3.3 Cleanliness
The surface of the fruit is free of dirt, dust, insect eggs, insect feces and other dirt that affects the appearance. 3.4 Good
The fruit has no mechanical damage, pests or rot, and is completely suitable for consumption. 3.5 Horizontal diameter
The longest line segment between the suture line and the horizontal section of the back of the fruit, expressed in millimeters (mm). 3.6 Odor
The bad smell of other substances absorbed by the fruit or the abnormal smell and taste caused by the deterioration of the fruit. 3.7 Abnormal external moisture
The moisture left on the surface of the fruit after rain or washing with water. 3.8 Fully developed
The fruit has grown to the proper size and shape. 3.9 Ripe
The fruit has reached the stage of full development and shows the characteristics of the variety. 3.10 Maturity
The different stages of the fruit ripening process.
3.10.1 Seventh maturity: The base green or green color begins to fade, the fruit is fully developed, the fruit surface is basically flat and has no pits, and there are a few pit marks near the suture line of mid- and late-maturing varieties, and the fruit surface is thick and hairy. 3.10.2 Eighty-mature: The green color obviously fades from the top of the fruit, and it becomes light green or light yellow.

Approved by the Ministry of Commerce of the People's Republic of China on December 30, 1992 and implemented on June 1, 1993
SB/T 10090—1992
3.10.3 Ninety-mature: Most of the green color fades, showing the base color of the variety, such as white, milky white, orange-yellow, with less hairs, and most of the colored varieties are colored. The flavor of the variety is expressed. 3.10.4 Tenth-mature: The hairs on the fruit fall off easily, and there is no residual green. The nectar peach is soft and juicy, the skin is easy to peel off, and the juice will flow and burst when slightly pressed; the hard peach begins to become soft.
3.11 Solute
Commonly known as water honey, the original pectin is significantly reduced when peaches are ripe, the cell membrane of the pulp cells becomes thinner, and some cells rupture, allowing the intracellular solutes to seep out of the intercellular space, so that the flesh becomes soft and juicy. 3.12 Water solute
That is, hardness. When fully mature, the middle gelatin layer is hydrolyzed to become powdery and cottony. 3.13 Insect damage
Injury to the fruit bitten by insects.
3.14 Insect fruit
Mainly refers to the fruit damaged by borer.
3.15 Tolerance
There may be negligence in the post-harvest grading of peaches, as well as quality changes that may occur during handling, storage and transportation. A permissible limit lower than the quality of this grade is specified.
