3 Terminology
3.1 Broken tip bamboo shoots
Sensory inspection of canned foods
Packaging, labeling, transportation and storage of canned foods Bamboo shoots with a cross-sectional diameter of 5 to 15 mm at the broken tip. 3.2 Trimmed bamboo shoots
For bamboo shoots with a trimmed part on the body, the depth of the V-shaped incision at the trimmed part shall not exceed one-half of the bamboo shoot meat, and the length shall not exceed one-quarter of the bamboo shoot
length.
3.3 Injured bamboo shoots
The length of the injured part of the bamboo shoot body shall not exceed one-third of the length of the bamboo shoot, and the depth of the injured part shall not exceed the thickness of the bamboo shoot meat. 3.4 Half a bamboo shoot
Slice a bamboo shoot longitudinally or crosswise in half or more. 3.5 Crude fiber
The bamboo shoot is too old and has a residue-like feel when eaten.
3.6 White precipitate
Amino acids contained in the bamboo shoot itself, white in color, often precipitated on the cut surface of the bamboo shoot or inside the bamboo shoot node. 3.7 Root nipple
Root bud at the base of the bamboo shoot.
3.8 Bamboo shoot skin

Canned products mixed with injured bamboo shoots, broken bamboo shoots, trimmed bamboo shoots, bamboo shoot tips, half bamboo shoots, and irregular bamboo shoots. 3.12-piece canned winter bamboo shoots in water
Canned winter bamboo shoots cut into thin slices of about 4.5mm thick, about 45mm long and about 25mm wide. 4 Product classification
Canned winter bamboo shoots in water are divided into three categories according to the shape of the bamboo shoots: whole pack, mixed pack and slice pack. Whole pack canned winter bamboo shoots in water, product code 812. 4.1
According to the size of the bamboo shoots, they are divided into large size 812L (net weight 2950g for 3 to 6 pieces). Medium size 812M (net weight 2950g for 7 to 10 pieces). Small size 812S (net weight 2950g for 11 or more pieces). 4.2 Mixed canned winter bamboo shoots in water, product code 8121. 4.3 Canned winter bamboo shoots in water, piece pack, product code 8122. 5 Technical requirements
5.1 Raw and auxiliary materials
5.1.1 Winter bamboo shoots should be fresh, tender, milky white or light yellow, free from mold, pests and mechanical damage. Slight damage to the roots is allowed, but the bamboo shoots should not be damaged. 5.2 Sensory requirements
Should meet the requirements of Table 1.

" Bamboo shoots are yellowish white and shiny; " Bamboo shoots are light yellow, and some bamboo shoots are allowed to be light yellow or off-white; "Color" The root nipple is allowed to be light gray or slightly reddish, and some bamboo shoots are allowed to be slightly reddish, or even light red; The soup is clear, and it is allowed to have "luster", and the root nipple is allowed to have "luster; The soup is allowed to be slightly turbid [a small amount of white precipitate
[light gray or light red; The soup is allowed to have Bamboo shoots are relatively clear, with a little bamboo shoots being allowed. The taste and smell have the taste and smell of canned winter bamboo shoots in clear water, without any peculiar smell. The bamboo shoots are tender and firm, with the tips being complete. The bamboo shoots are tender and firm, with the tips being tender and firmer than the bamboo shoots. The base incision is neat and flat, and the bamboo shoots are complete and flat. The bamboo shoots are plump, and the broken groups are plump and have a consistent appearance. The same bamboo shoot has a plump body and a uniform appearance. The number of bamboo shoots and trimmed bamboo shoots does not exceed half. [In canning] The size is roughly uniform
