Traits Character identification (1) No needle squid, the inner shell is long and oval and flat, with thin edges, thick middle, long 9-14cm, 2.5-3.5cm wide and 1.2-1.5cm thick. Magnetic white ridges on the back of the ridge, slightly red on both sides, subtle visible small punctiform processes, the formation of nearly parallel semi-annular texture; ventral surface white, with fine wavy transverse layer from the end to the middle; horny edge translucent, The tail is wider and has no bones. Light weight, loose texture, easy to break, cross-section silty, loose loose layer pattern. Slight gas, slightly salty taste. (2) Gold squid, the inner shell is larger than the former, is 13-23cm long and is approximately 6.5cm wide, and the thickest part is located in the first half, 0.8-1.2cm thick. Obvious backside defects, slightly arranged in layers; ventral wavy transverse striae, accounting for most of the whole, with longitudinal troughs in the middle; keratinocytes in the tail gradually widening, turning toward the ventral surface, with a bony needle at the end, mostly broken off . (3) Needle squid, the inner shell is slender, the length of the male inner shell is 6 times the width, the length of the female inner shell is 4 times the width, and the bone needle at the end of the inner shell protrudes sharply. (4) White-spot squid, thick inner shell, long oval. About 2.5 times as long as the width, the back of the bulge, there are large particles, concave convex front concave. The back end has a coarse bone, and there is a shallow ditch at the center of the transverse striation. (5) Tabby squid, the inner shell resembles white spotted squid. (6) It is intended that the squid be similar to the golden squid in its inner shell but with a shorter cross-section. Physical and chemical identification (1) Dilution of hydrochloric acid with dilute hydrochloric acid produces bubbles. (2) Take this product powder 10g, double wrap filter paper gauze, placed in the Soxhlet extractor, with petroleum ether 150ml reflux extract to colorless, take the extract to dry, the residue is dissolved in CHCL32ml, have to test Liquid I. The residue extracted with petroleum ether was placed in a 50-ml round-bottomed beaker, decocted with 30 ml of water for 2 hours, filtered, and the filtrate was taken to obtain degree of solution II. 1 Take the test solution I1ml in the test tube, slowly add concentrated H2SO41ml along the wall, and let stand for 10min. The CHCL3 layer is yellow with sky blue fluorescence and the middle orange yellow ring. (Salkowski reaction) 2 Take the test solution II1ml in a test tube, add the same amount of ninhydrin reagent, heated in a water bath for 10 minutes, and show lavender. (Amino acid reaction). Microscopic identification Powder characteristics: almost white. Under the microscope, irregular transparent flakes can be seen, some with fine stripes, and irregular fragments, with a reticulated or textured surface.
