3.1 Broken tip bamboo shoots
Sensory inspection of canned food
Packaging, marking, transportation and storage of canned food Bamboo shoots with a cross-sectional diameter of less than 35% of the base diameter of the bamboo shoot body and basically intact in shape. 3.2 Bald bamboo shoots
Bamboo shoots with a cross-sectional diameter of 35% to 60% of the base diameter of the bamboo shoot body and a pagoda-shaped shape. 3.3 Segmented bamboo shoots
Bamboo shoots with a cross-sectional diameter of more than 60% of the base diameter of the bamboo shoot body and approximately the same thickness at the top and bottom. 3.4 Split bamboo shoots

The bamboo shoots are too old and have a residue feeling when eaten.
4 Product classification
Small bamboo shoots are divided into six grades according to the diameter of the base of the bamboo shoots and the length of the bamboo shoots. Their codes are shown in Tables 1 and 2.

Table 3 Sensory requirements
Superior quality
"The bamboo shoots are white or yellowish white, and the color in the same can is roughly uniform and shiny; the color is still uniform; the soup
First-class quality
"The bamboo shoots are white, yellowish white or light yellow
"The color in the same can is relatively uniform, slightly
"The bamboo shoots are white,
""The soup is relatively clear, and a little bamboo shoot debris is allowed" Shiny: a little bamboo shoot debris is allowed【The juice is still clear, and a small amount of bamboo shoot debris is allowed
Taste and smell It has the taste and smell of small bamboo shoots canned food, without any peculiar smell "The bamboo shoots are tender, the cut is smooth,
The cut is still smooth, the bamboo shoots are tender, the cut is relatively smooth, the bamboo shoots are tender, the shape is complete; there are no split bamboo shoots and crude fiber shapes are relatively complete; there are no split bamboo shoots and segments; the shape is basically complete: there are no split bamboo shoots and segments; the tissue shape is not broken bamboo shoots and bald bamboo shoots; individual bamboo shoots are allowed to be eaten with slight "strip bamboo shoots, no obvious crude fiber bamboo shoots; broken tips are not more than 5% of the net weight per can; the amount of broken tips and bald bamboo shoots per can is not more than 10% of the net weight.
