1. Effects of processing and packaging on bioactive compounds of curriola jelly [Pouteria ramiflora (Mart.) Radlk.] during storage
Abstract The objective herein was to evaluate the effect of processing, packaging type (with and without exposure to light) and storage time on the quality of functional attributes of jelly prepared from curriola pulp. The experimental design was a completely randomized 2 × 5 factorial design, with two levels of packaging (transparent and amber) and five st

2. Drying kinetics, structural characteristics and vitamin C retention of dedo-de-moça pepper (Capsicum baccatum) during convective and freeze drying
The main objective of this study was to evaluate the effect of the drying process on the vitamin C levels and physical properties of dedo-de-moça pepper. The drying kinetics and the structural properties were determined as a function of moisture content. Convective drying was compared with freeze-drying in terms of product quality, structural properties, re

4. MamÃo (Carica papaya L.) liofilizado em pÃ: avaliaÃÃo das caracterÃsticas fÃsicas, fÃsico-quÃmicas e higroscÃpicas / Papaya (Carica papaya L.) lyophilized powder: evaluation of physical, physicochemical and hygroscopic characteristics
Papaya (Carica papaya L.) is a tropical fruit known and appreciated worldwide. Their sensory and nutritional characteristics contribute to the wide acceptability of this fruit. However, in the post-harvest loss is high due to its highly perishable. In this context, the lyophilization appears as a promising process for dehydration of papaya, because is a dryi

7. Strategies to alleviate the incidence of ascites in broilers: a review
Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrit

9. Efeito da temperatura de extrusão, umidade da materia-prima, teor de amido e sacarose nas caracteristicas tecnologicas e nutricionais de produtos extrusados de germe de trigo
Wheat germ component is rich in vitamins, minerals, fat content and good quality proteins. The amount of wheat germ used as food in human consumption is very low compared to the amount used as feed for animal. This fact could be explained by some problems in raw wheat germ. The extrusion cooking process - High Temperature Short Time was applied to wheat germ
