Problems solved by technology

The mantle of Pinctada martensii is relatively thin, the muscular tissue and mucus cells in the mantle are underdeveloped, and the mantle is not strong enough to be stimulated by surgery. The current general small piece preparation method can achieve better pearl breeding effect; while the large pearl oyster The mantle of the mother oyster is thick, and the muscle tissue and mucus cells are well developed. The mantle shrinks severely during the preparation of small pieces, which makes the mantle thicken and harden, and produces a large amount of mucus, which greatly increases the difficulty of preparing small pieces. Seriously affected the quality of the prepared small tablets

Embodiment Construction

[0015] The method for preparing the small pieces of the mantle of Pinctada maxima is carried out in the following steps:

[0016] 1. Low-temperature freezing treatment of small shellfish

[0017] Cleaning the small shellfish of Pinctada grandis used to prepare the small pieces is placed in filtered seawater at 7-10° C. and freezing until the small shellfish is in an open state.

[0018] 2. Kaibei

[0019] Use a knife to cut off the adductor muscle and visceral sac of the small piece of shellfish that has been frozen and in an open state, divide the shell body into two halves, and then remove the visceral sac so that the complete mantle remains on each shell, and then use sterilized seawater Rinse away dirt from the mantle, etc.

[0020] 3. Cut out small pieces of mantle

[0021] Cut the mantle directly on the shell with a knife along the direction perpendicular to the edge of the mantle, so that the mantle is formed into several strips with a width of 3-6mm; Square mantle ...

Abstract

Invention provides a method for preparing big black shell mantle flakes, which comprises the following steps: putting big black shells for preparing the flake into low-temperature sea water to perform freezing treatment before slicing so that the big black shells are in a shock or dead natural ringent state and mantles lose reaction and shrinkage capabilities as well as mucilaginous capability to an operation stimulus; and after opening the shell, slicing the mantle flakes one by one on the shell directly. The method greatly reduces the difficulty for preparing the big black shell mantle flakes and simplifies the operation process, and the prepared mantle flakes have good effect of growing cultured pearls.

Description

technical field [0001] The invention relates to the technical field of pearl cultivation, in particular to a preparation method of small pieces of the mantle of Pinctada maxima. Background technique [0002] Pearls cultivated from the mother-of-pearl are commonly known as "South Sea pearls". They are currently the most precious pearls in the world, and they are mainly produced in countries such as Australia and Indonesia. Although my country is a big producer of seawater pearls, it mainly produces traditional "South Pearls", that is, small, low-value pearls cultivated from Pinctada martensii. In recent years, due to the blind expansion of the scale of "South Pearl" breeding and the serious decline in quality, my country's "South Pearl" has gradually lost its competitiveness in the international jewelry market. my country's Guangdong, Guangxi and Hainan coasts are rich in natural resources of Pinnacles macrophylla. Although South Sea pearls can be produced in small quantitie...
