Harvesting and processing of peach gum
Peach, plum, apricot, cherry and other tree trunks secrete gum called peach gum. Peach gum is a translucent polysaccharide with a wide range of applications. The textile industry is used as acid printing paste, kaleidoscope carving process as protective adhesive, printing industry as gold powder adhesive, edible, medicinal and paper adhesive, instead of imported Arabic gum. This paper introduces the harvesting and processing methods of peach gum.
First, harvest peach gum in the growing season of peaches, plums, apricots and cherries. The gum on the trunk of the above tree species is cut with a knife and dried in the sun, which is the raw material of peach gum. Do not hurt the bark when picking peach gum.
Second, to remove impurities, soak the dried peach gum material in water (solid-liquid ratio is 1:2). When the raw material is swollen, tear it into fine pieces, remove the impurities such as bark, sawdust and sand, and then drain the water to move on to the next process.
Third, hydrolysis will remove the impurity raw materials and water into the jacket reaction pot, stirring with steam or oil bath heating, the temperature is controlled at about 120 ℃. The reaction can be completed in 3-6 hours, then filtered through a 40-mesh copper wire screen, and then loaded into a large cylinder, that is, the product to be bleached.
Fourth, bleaching will be bleached products are strongly stirred, and gradually add 10% sodium chlorate bleach, and add 0.1% rain 0.2% formaldehyde or 0.005% carbendazim antiseptic. That is, it is a semi-finished product that does not fade.
Fifth, dry in the stainless steel plate with steam blowing, or directly in the pot with fire heating, the heating process should be constantly turned, after drying to get 50% water paste products. If dried or dried, pure solid peach gum can be obtained.

Key points of summer management of Taoyuan
Summer is an important period for branch growth and fruit expansion of peach trees.
