Basic introduction of Huaiji pine resin

Pine trees contain a colorless and transparent viscous liquid, which is a solution formed by dissolving solid resin acid (70%~80%) in terpenes (20%~30%). After steam distillation, turpentine and rosin can be obtained from pine resin

The sugars produced by photosynthesis in pine needles undergo complex biochemical changes to form pine resin in the thin-walled cells of the wood, which seeps into the resin channels through the walls of the bleeding cells. Resin channels are a unique structure of pine trees, forming three independent systems in the xylem, needles, and primary cortex. There are two types of resin channels in the xylem: longitudinal and transverse, which communicate with each other in the wood to form a resin channel system. When harvesting pine resin, as long as the outer edge of the trunk is cut, the resin will flow out through the resin channel system

Its juice is white, and turpentine is a resin secreted by pine trees. When it first flows out of the trunk, it is colorless and transparent, with a turpentine content of over 30%. After coming into contact with air, the turpentine gradually evaporates, and with the invasion of external moisture, some of the resin acid crystallizes out, and the turpentine gradually becomes a honey like semi fluid. Pine resin is mainly composed of resin acids and terpenes, and also contains a small amount of impurities and moisture
