Background

Yangxin pear is produced in Yangxin county of Shandong province, the cultivation history is long, large-area cultivation is carried out in Tang and Ming times, 20 ten thousand mu of the prior pear gardens are known as 'hometown of pear', Yangxin pear is frequently covered and pressed in countryside in national evaluation, and the cicada joins the cinnamon crown. Yangxin pear is large, the average single fruit weight is 175 g, the shape is beautiful, the pear is in an inverted egg shape, the pear is named after the base part of the pear protrudes like a duck head, the pear is yellow green at first, the pear is golden yellow after being stored, the pear has thin skin and small core, the pear juice is rich in dregs, aromatic flavor, crisp and tasty, moderate sour and sweet taste, unique flavor, the sugar content is up to 12%, the pear is called 'natural nectar', the pear is rich in nutrient components such as sugar, vitamin C, calcium, phosphorus, iron and the like, the pear is called from China and abroad due to excellent quality, the pear contains 10-13% of sugar generally, contains fruit acid, protein, fat, multiple vitamins, mineral substances and carbohydrate, has the effects of clearing lung, reducing phlegm, moistening the early and facilitating defecation, has an auxiliary treatment effect on diseases such as cough and asthma, hypertension and the like, and is called as a good product in the fruit. According to the Chinese pharmacopoeia (the Chinese materia medica is new), the pear is sweet in nature, cold and slightly sour, and has the effects of clearing heart and lung, benefiting intestines, relieving cough and eliminating phlegm, clearing throat and reducing internal heat, and dispelling alcohol and detoxifying. The compendium of materia medica specifies the function of the pears as: "live one clears heat of six fu organs and mature one nourishes yin of five zang organs".

In recent years, the plantation of the pears is rapidly developed in the northwest and the Shandong province, but the fresh-keeping time of the pears is short, so that the pears are mainly eaten in the fresh state. In recent years, the short-term production of the pears leads the price of the pears to be continuously reduced, a large number of pears are rotten in winter, the planting enthusiasm of fruit growers is seriously contused, and the pear industry in China faces the continuous atrophy risk. Although the Chinese pear fresh-keeping technology has achieved certain effect and is applied to practice, the cost is high after long-time preservation, and the requirement of industrial development of the pears is difficult to adapt, so that the development of the pear health-care food becomes the subject of the development of the Chinese pear industry, and the research and development of the nutritional and health-care pear biological product has important significance for promoting the development of the pear industry.
