A method for screening fruit mulberry varieties and improving fruit quality

Abstract

The invention discloses a mulberry variety screening and fruit quality improving method. According to a research system, chemical components and mineral elements of 13 mulberry varieties are analyzed, data are processed by using partial least squares, a main component analysis method and a typical relation analysis method, results show that vitamin C and titratable acid in mulberry may be key components which affect active components of the fruits, mineral elements such as zinc and copper also play corresponding roles, rutin, anthocyanin, vitamin C and titratable acid in the fruits are in remarkable positive correlation, the content of the titratable acid is one of significant factors which determine the flavor of the mulberry, and the titratable acid plays a significant role in stabilizing the anthocyanin, the vitamin C and the rutin. Calcium, magnesium, potassium and selenium in the mineral elements are in remarkable positive relation, and another positive relation group includes copper, iron and zinc. The research results show that reference bases and referential research means are provided for mulberry variety screening and fruit quality improvement.

Description

technical field [0001] The invention belongs to the field of fruit mulberry quality research, in particular to a method for screening fruit mulberry varieties and improving fruit quality. Background technique [0002] Berry fruits, which have received a lot of attention over the past few years, are good sources of health beneficial compounds. The fruit of the mulberry tree is a typical representative of emerging berries. The mulberry tree is a deciduous tree with a height of 10 meters to 13 meters, including drooping and cone shapes ( and 2013, Lin and Lay, 2013). Mulberry tree presents very sweet fruit. In Europe and other regions, fruit mulberry is an emerging high-quality fruit. At the same time, because of its high bioactive compounds, it plays a very important role in the food industry. It contains different chemical components and different The amount of antioxidant performance ( Papetti Ognjanov and 2015). [0003] China is the origin center of mulberry ...

Problems solved by technology

[0005] The paper "Partial Least Squares Analysis of the Relationship Between Chemical Composition and Phenolic Compounds in Blueberry Cultivars" used partial least squares method and principal component analysis to explore the intrinsic relationship between the chemical components and mineral elements of different blueberry varieties and the abundance of phenols. The fruit is classified, but the influence relationship between different component groups has not been analyzed. In the process of actual planting and material selection, it is impossible to effectively control the quality of blueberry fruit as a whole, or to effectively screen for improved varieties.
