Abstract:
The processing of fruits and vegetables into new products, as well as a way of reducing losses in nature, also provide conservation and consumption for the harvest period. It is important that products reach the market by meeting the quality parameters and the growing demand of the population for products with more nutrients. In this way, the objective of this work was to evaluate physico-chemical characteristics and to quantify the bioactive compounds in commercial brands of sweet in bulk (guava and banana), fruit pulp (acerola and guava) and tomato extract. The experiment was installed in a completely randomized design, with the results submitted to analysis of variance and the means compared by the Tukey test (p <0.05). The physico-chemical and quantification of bioactive compounds of the commercial products were performed in quadruplicates, the results being expressed as general mean ± standard deviation. In relation to sweets in bulk of guava, Brand 1 was distinguished by the ratio SS/AT (123.4) and phenolic compounds (188.01 mg.100g-1 gallic acid). For the sweet in bulk of banana, Mark 3 presented 159.2 SS/AT ratio. For acerola pulp, Brand 3 did not reach adequate values for SS (4.3%) and Brand 4 was highlighted by the concentration of ascorbic acid (1492.63 mg.100g-1) and phenolic compounds (1137.52 mg .100g-1 gallic acid). For the tomato extract, Mark 3 presented 19.8 SS/AT ratio. Mark 1 was highlighted by the concentration of carotenoids (10.57 μg.100g-1) and phenolic compounds (50.65 mg.100g-1 gallic acid). It was concluded that: for sweet in bulk of guava (Brand 1), for sweet in bulk of banana (Brand 4), for acerola pulp (Brand 4), for guava pulp (Brand 2) and for tomato extract (Mark 1) were the brands that presented the best results.
