The instruments used are a...
Evaluation of total phenolic compounds and antioxidant activity for the drying ...
Guiné, Raquel; Gonçalves, Fernando; Alves, Mariana; Oliveira, Solange; Barroca, Maria João; Correia, PaulaChemically, the phenolic compounds are cyclic benzene compounds having one or more hydroxyl groups directly associated to the ring structure. While they contain alcohol groups, they do not show properties of alcohols. The phenols can be distinguished into two groups: non-flavonoids and flavonoids [1-4]. Bananas cv. nana and pears cv. D. Joaquina were subject to drying (at 70 ºC) for comparison of their propert...
Phenolic Compounds in Red Fruits Produced in Organic Farming at Maturation Stage
Soutinho, Susana; Guiné, Raquel; Jordão, António; Gonçalves, FernandoThe agricultural organic farming is different from conventional farming in a way that is aimed at providing a balanced and constructive action in agricultural systems. With the increase in intensive agriculture, undesirable changes were being observed in ecosystems with irreparable damage being caused to the natural equilibrium.
