Research on Techniques and Industry Situation and Prospect for Peach Processing in Domestic and Aboard(国内外桃加工科技与产业现状及展望)
摘要
China has the largest cultivated area and production quantity of peach in the world. In 2017, cultivated area and yield of peach in China were accounted for 51.17% and 57.96% of total in the world, respectively. The harvested period of peach was short and seasonal, which was mainly in summer. In order to avoid wasting, the processing products and technologies of peach were developed. This paper reviewed the development situation of peach industries in China and abroad. Technologies of peeling, sterilization and texture maintenance in canned peaches industry, color maintenance and stabilization processing technologies during peach juice production, and hot air drying, freeze drying and instant controlled pressure drop drying technologies during dehydrated peach products processing were emphatically introduced. The development direction of peach processing technologies and equipments for productions of canned peach, peach juice, dehydrated peach products, and fermentation peach were also focused. It also discussed the necessity of transforming peach industry from traditional processing to modern processing industry, and promoting health and rapid development of peach industry in China. Finally, the prospect of development trend of peach processing industry in China was also expected.(中国的桃种植面积和产量均为世界第一,2017年我国桃种植面积和总产量分别占世界总种植面积的51.17%和总产量的57.96%。桃生产的季节性较强,在夏季集中上市,为降低因产季集中造成的浪费,桃深加工科技应运而生。阐述了国内外桃加工科技与产业现状及发展趋势,重点介绍了桃罐头生产加工中的去皮、杀菌及质构保持技术,桃汁(浆)生产加工中的色泽保持和品质稳定性保持技术,以及脱水桃制品生产中的热风干燥技术、真空冷冻技术和压差闪蒸技术。分析了我国桃罐头、桃汁、桃脱水制品、桃发酵制品等的加工技术与装备的发展方向与趋势；论述了我国桃由传统加工向现代加工产业转变和推进桃产业健康快速发展的必要性。最后对我国桃产业发展前景进行了展望。)
