Chemical compositional characterization of some apple cultivars

Development and optimization of a HPLC-RI method for the determination of major sugars in apple juice and evaluation of the effect of the ripening stage

“…The D-fructose level also increased during ripening but decreased proportionally in relation to the other sugars. Several studies have shown that levels of sucrose, D-glucose, and D-fructose increase with advanced ripening of fruits (Wu et al, 2007). As for the the levels of sugar in the juice, it was also possible to observe that in the pre-ripening period of the Fuji Suprema cultivar, the apples already had levels of 50, 86, 83, and 32% of sucrose, D-glucose, D-fructose, and D-sorbitol, respectively, considering the concentration of juice of senescent apples to be 100%.…”

“…Besides compromising the proof of authenticity, this also has an effect on the sensory properties and nutritional value of the apple products (Wu et al, 2007;Wosiacki et al, 2007). The major carbohydrates found in apple juice are the sugars sucrose, D-glucose, and D-fructose and the polyol, D-sorbitol (Wosiacki et al, 2007;Hecke et al, 2006).…”

Biochemical compositional and technological characterizations of black and white myrtle (Myrtus communis L.) fruits

“…The amounts of citric, malic and ascorbic acids were reported as 3.21, 1.11 and 0.19 g/kg of FW in strawberry fruits by Perez et al (1997). Tartaric, malic and citric acid contents of some apple cultivars ranged from 0.014 to 0.030 mg/L, 2.73 to 7.07 mg/L and 0.044 to 0.093 mg/L, respectively (Wu et al 2007). The mineral contents of black and white myrtle fruits were determined by ICP-AES (Table 2).…”

Fruit quality of ‘Eva’ e ‘Princesa’ apples grown under nitrogen fertigation in semiarid climate

“…In Brazil, apple cultivation has expanded for nontraditional regions of growing temperate fruit crops (Petri et al, 2011) detaching the research works performed successfully in semiarid climate of São Francisco Valley (Lopes et al, 2012Santos, 2013;Oliveira et al, 2013) and west region of São Paulo State (Chagas et al, 2012) and Minas Gerais state (Oliveira et al, 2014). Additionally, 'Eva' and 'Princesa' are early season apple cultivars with low chilling exigency, adapted for regions with soft winter, which has made possible to grow apples in areas with different climates, such as Bahia and Pernambuco states (Lopes et al, 2012;.…”
