Características físicas e químicas de frutos de pupunheira no Estado do Pará
(Universidade Federal do Pará, 2013-09) CARVALHO, Ana Vânia; BECKMAN, Jacqueline Chaves; MACIEL, Renan de Almeida; FARIAS NETO, João Tomé de
The aim of this study was to assess the physical and physical-chemical characteristics of the fruits of 21 reproductive peach palms to help guide future research on genetic improvements of the species, especially regarding the fruit pulp. Fruits from each genetic material were characterized by fruit and seed size, moisture, protein, lipid, ash, fiber and total carotenoids. Average values for all studied variables were significantly different among all individuals. Protein values ranged from 4.20 to 6.79%, especially for B04-P20 that showed the highest value. Lipid levels varied markedly, with values ranging between 8.25 and 40.83%, and matrix B02-P30 presenting the greatest levels of lipids. Total carotenoids ranged from 8.02 to 124.90 mg/g, with matrices B02-P30 (124.90µg/g) and B05-P45 (123.04µg/g) presenting the highest values. The high total carotenoid values observed indicates that peach palms could make a significant contribution to antioxidants in the diet. Overall, the physical and physical-chemical assessment revealed significant differences among the studied reproductive individuals for the characters studied, indicating that this species offers considerable promise for future research on genetic improvements.

Nutritional potential of green banana flour obtained by drying in spouted be
(Sociedade Brasileira de Fruticultura, 2013-12) BEZERRA, Carolina Vieira; RODRIGUES, Antonio Manoel da Cruz; AMANTE, Edna Regina; SILVA, Luiza Helena Meller da
This study evaluated the chemical composition of peeled and unpeeled green banana Cavendish (AAA) flour obtained by drying in spouted bed, aiming at adding nutritional value to food products. The bananas were sliced and crushed to obtain a paste and fed to the spouted bed dryer (12 cm height and T = 80 ºC) in order to obtain flour. The flours obtained were subjected to analysis of moisture, protein, ash, carbohydrates, total starch, resistant starch, fiber. The green banana flours, mainly unpeeled, are good sources of fiber and resistant starch with an average of 21.91g/100g and 68.02g/100g respectively. The protein content was found in an average of 4.76g/100g, being classified as a low biological value protein with lysine as the first limiting amino acid. The results showed that unpeeled green banana flour obtained by spouted bed drying can be a valuable tool to add nutritional value to products in order to increase their non-digestible fraction.

Qualidade pós-colheita de cultivares de bananeira do grupo 'maçã', na região de Belém - PA
(Universidade Federal do Pará, 2011-12) CARVALHO, Ana Vânia; SECCADIO, Lara Lima; OLIVEIRA JÚNIOR, Moisés Cordeiro Mourão de; NASCIMENTO, Walnice Maria Oliveira do
The present study aimed to characterize the physical and physical-chemical properties and perform sensory evaluation of ripe fruits of three banana cultivars of the subgroup 'Maçã ' at different stages of maturation. Bunches of Caipira, Thap Maeo, and BRS Tropical cultivars were harvested at stage 2 of color peel (green-mature) and stored at room temperature. They were evaluated at color peel stages 2, 3, 5, 7 with respect to length and diameter of the fruits. The following properties of the pulp were investigated: firmness, pH, soluble solids, titratable acidity and sugar concentration (reduced, not reduced and total). Fully ripe fruits were also analyzed regarding the sensory acceptance through the attributes aroma, pulp color, texture, and flavor of fruit. As the ripening progressed, acidity, soluble solids and sugars increased, factors responsible for the fruit flavor, as well as the decrease in fruit firmness and the pH reduction were observed for all cultivars. With respect to sensory analysis, the Tropical and Thap Maeo cultivars presented the highest average scores for all sensory attributes evaluated.
