枸杞深加工产品开发现状及研究进展

枸杞作为一种药食同源的经济林果,富含多糖、类胡萝卜素、类黄酮、甜菜碱、牛磺酸等多种功能性成分,具有增强免疫调节、抗衰老、预防癌症和肿瘤生长、降低血糖和血脂水平等多种功效,消费者对枸杞相关产品的需求也日益增加。枸杞生长性状属无限花序,果实成熟期较长为每年6～10月份;然而,枸杞果实在成熟后期快速软化,使其极易受到机械损伤和病原微生物侵染,限制果实的贮藏和运输;因此,在果实成熟期为降低枸杞果实的损耗和迎合消费者对枸杞保健功能的需求,需要在成熟期内对果实进行深加工处理。阐述了枸杞的主要营养价值和保健功效,并提出传统加工产业与现代消费升级引起的供需矛盾;介绍了枸杞深加工产品和配套技术设备的相关产业现状,分析了枸杞产业精深加工的市场需求和产品研发的未来发展趋势,并指出了枸杞深加工产品和新技术、新装备在枸杞深加工产业的应用前景以及面临的难题和挑战,为枸杞深加工产业的发展提供理论参考。

Development Status and Research Progress of Deep Processing Products of Lycium barbarum

As an economic fruit which is homology of medicine and food, Lycium barbarum is rich in polysaccharides, carotenoids, flavonoids, betaine, taurine and other functional components. It also serves many functions such as enhancing immune regulation, anti-aging, preventing cancer and tumor growth, reducing blood glucose and lipid level, etc. And the demand of Lycium barbarum related products is increasing. The growth character of Lycium barbarum belongs to infinite inflorescence, and the ripening period of fruit is longer from June to October. However, Lycium barbarum fruit softens rapidly in the later stage of ripening, which leads to vulnerable to mechanical damage and pathogen infection, limiting the storage and transportation of fruit. Therefore, in order to reduce the loss of Lycium barbarum fruit and meet the needs of consumers for health care function, it is necessary to carry out deep processing of Lycium barbarum during ripening period. This paper expounded the main nutritional value and health care effect of Lycium barbarum, introduced the current situation of deep processing products and related technical equipments of Lycium barbarum, and pointed out the development prospect, direction and challenges of deep processing products of Lycium barbarum, which provided theoretical reference for the development of deep processing industry of Lycium barbarum.
