Copoazú (Theobroma grandiflorum) is an Amazonian fruit with great economic potential, due to its high nutritional value, being an important source of ascorbic acid and phenolic compounds. Its pulp of high viscosity and acidity makes its industrial processing difficult. The present study aims to evaluate the effect of enzymatic liquefaction with two commercial pectinolytic enzymes (Rapidase® LIQ Plus and Rapidase® Citrus Cloudy) at different temperature conditions (15 to 45 °C) and incubation time (2 to 5 h) on the Physicochemical characteristics of the juice and the technological properties of the copoazú residue, under a response surface design. Juice yields of up to 87.96% were obtained with the Rapidase® LIQ Plus enzyme at 15 ° C and during 2 h of incubation, showing the use of hydrolytic enzymes as an ideal biotechnological alternative for the physicochemical and rheological adaptation of the copoazu pulp, with potential positive impact for its implementation in remote areas, where the fruit is produced, eliminating the problems generated by the high viscosity of the pulp. The copoazú residue has a high content of dietary fiber (42.48% on a wet basis). In addition, it presented excellent characteristics such as swelling capacity (CH) (3.85 g of water / g of dry matter) and water retention capacity (CRA) (3.94 g of water / g of dry matter). Consequently, the solid byproduct from the enzymatic clarification of copoazú pulp has quality characteristics similar to those registered in commercial fiber additives used by the industry.

The physicochemical, technological, microbiological and antioxidant properties of the passion fruit epicarp (EM, Passiflora edulis f.flavicarpa) were evaluated. The results showed a high dietary fiber content both soluble and insoluble (26.62 and 44.84 g / 100 g d.b. respectively) and high protein content (11.87 g / 100 g b.s.). In order to evaluate the potential use of passion fruit epicarp as an input to enrich food products, the emulsifying capacity (97%), swelling capacity (28.63 g / g d.b.), oil holding capacity (4.06 g / g d.b.), solubility (0.71 g / g d.b.) and the content of total carotenoids (3.86 mg β-carotenes / 100 g) were determined. Additionally, two techniques (DPPH and ABTS) with values of antioxidant activity of 33% (IC50 ≥ 250 μg / ml) and 2.09 μm / g d.b. were used to determine antioxidant activity. of EM respectively. The results of this study showed the potential use of the passion fruit epicarp as a functional ingredient in the food industry. [ABSTRACT FROM AUTHOR]

The shelf life of a product based on ground beef molded, with the addition of a functional ingredient (pecana nut) was determined. The storage was for 35 days at modified atmosphere (20 % CO2, 2 % de O2 and 78 % N2) at three temperatures: freezing (-18 °C), refrigeration (4°C) and room temperature (21 °C) and the shelf life was determined. By the statistical analysis, the functional product is accepted according to its physico-chemical, microbiological and sensory characteristics, indicating preference on the hedonic scale as acceptability on day zero and descriptive test, that is, on the characteristics of its attributes and 168 days of shelf life compared to150 days of the control product at -18°C and13 days at 4°C, while the control was 9 days. The Q10 value was 1.52 for the final product. [ABSTRACT FROM AUTHOR]
