Vitamin characterization and volatile composition of camu-camu (Myrciaria dubia (HBK) McVaugh, Myrtaceae) at different maturation stages

Abstract

During the process of fruit development there is synthesis and catabolism of compounds that culminate with the specific characteristics of each species, such as changes in color, size, acidity, vitamins content and volatile composition. In the present study was evaluated during the development of camu-camu (Myrciaria dubia (HBK) McVaugh, Myrtaceae) the contents of pH, At, SS (ºBrix), Vitamin C, polyphenols, (L *, a * and b *) coloration and volatile composition using the HSPME-CGMS technique, at different stages of development. During development, an increase in the ºbrix variable was detected (6.92 to 9.02), and a decrease in the levels of vitamin C 1150 mg/100 g and total polyphenols 1280mg / 100g. Regarding the volatile composition, there was a difference of compounds according to the stage of development analyzed. Among the identified components, terpenes were the major class of compounds at all stages of maturation (p<0.05). © 2021, Sociedade Brasileira de Ciencia e Tecnologia de Alimentos, SBCTA.
