Comprehensive evaluation of fruit quality of five Morella nana samples from Guizhou
摘要
Abstract
To evaluate fruit characteristics of the Morella nana resources in Guizhou,five fruit samples from the natural state were used as materials,and indicators such as single fruit weight,longitudinal and transverse diameters,fruit shape index,edible rate,color,and contents of soluble solids,total soluble sugar,titratable acid,total phenols,flavonoids,anthocyanins and vitamin C were measured and compared.The results showed that the single fruit weight of Morella nana was 3.30-5.57 g,and the edible rate was 75.05％-77.93％,both of which were significantly(p<0.05)lower than those of control(Huotan and Biqi);the anthocyanin content of the fruits was only 1.81-18.79 mg‧kg-1,which was significantly lower than that of control,and the lightness value(L*)and yellow and blue value(b*)of color were significantly higher than those of control;the soluble solid content was 6.48％-8.52％,and the total soluble sugar content was 1.23％-2.27％,both of which were significantly lower than those of control;the titratable acid content was 4.31％-5.63％,and the the total phenol content was 9.42-11.17 mg·g-1,both of which were significantly higher than those of the control;the flavonoid content was 0.63-0.93 mg·g-1,with only one sample being significantly higher than control.The contents of fructose,glucose and sucrose contents were 0.99-2.42 mg·g-1,1.08-2.24 mg·g-1,and 2.32-5.92 mg·g-1,respectively,all of which were significantly lower than those of control;the contents of citric acid,malic acid and vitamin C contents were 30.68-40.55 mg·g-1,1.96-3.47 mg·g-1,and 0.15-0.24 mg·g-1,respectively,all of which were significantly higher than those of control.Therefore,the main characteristics of Morella nana fruits in the natural state are low sugar,low anthocyanin and high citric acid content.This study preliminarily reveals the fruit quality characteristics of Morella nana and provides a theoretical basis for the later selection of excellent strains and the development of functional foods.关键词
