Qualidade fisiológica de sementes de milho doce classificadas pela espessura e largura

Sweet maize seeds present lower physiologic quality, when compared to regular maize seeds, due to the influence of several features, such as the seed size and shape. Thus, this study aimed at evaluating the seed physiologic quality of two sweet maize cultivars (BR-401 and BR-402), separately classified according to thickness, by using slotted screen sieves (8/64 x 3/4, 9/64 x 3/4, 10/64 x 3/4, 11/64 x 3/4, 12/64 x 3/4 and 13/64 x 3/4), and width, with round screen sieves (17/64, 18/64, 19/64, 20/64, 21/64 and 22/64). For each cultivar, sorted lots were compared with the unrated batch, following a completely randomized design, in a 2x7 factorial scheme, with four replications. The biometric parameters evaluated were sieve retention, 100 seeds weight and water content. The physiologic quality was determined according to the first counting, germination, cold test, accelerated aging, electric conductivity and seedling emergence in the field. The classification with sieves improved the physiologic quality of sweet maize seeds. Seeds with intermediate thickness, for both cultivars, generally presented greater vigor. Concerning width, larger seeds, for the BR-401 cultivar, and intermediate seeds, for the BR-402 cultivar, showed better physiologic quality.

Produção de hidrolisado enzimático de farinha de batata-doce para fermentação etanólica

Recently there is a great quest of producing alcohol from starchy resources, replacing the sugar cane. The most common starchy sources are cassava, maize and sweet potatoes and a lot of research are been realized with excellent results. In this work it was evaluated the influence of the concentration of dry matter on the enzymatic hydrolysis process of starch from sweet potato for ethanol production. Through the sweet potato was produced a flour using a low-cost method and easy operation equipments. The sweet potato flour was characterized physical and chemically and from these results was prepared the treatments for enzymatic hydrolysis. The experimental design considered as independent variable the dry matter concentration of the sweet potato flour in 3 levels; 10, 15 and 20% in the formulation of suspensions. The other variables were keeping constant being: temperature in the 1° hydrolysis step of 90°C and time of 2 hours; temperature in the 2° saccharification step of 60°C and time of 17 hours. The hydrolysates obtained at the three assays were transferred to six liter enlerynmeyer and inoculated with a biologic catalyst, Saccharomyces, dehydrated yeasts of Saccharomyces cerevisiae CAT 1, at a rate of 5% in weight. The flasks were placed in a shaker type orbital with controlled temperature of 30°C during a time of 15 hours. The initial reducer sugars concentration and respective ethanol concentrations in wine were: 11.2% glucose and 2.16% ethanol in the suspension with 10% of dry matter; 13.5% glucose and 4.39% ethanol with 15% and 17.5% glucose and 6.03% ethanol in suspension with 20% of dry matter. ix The results showed that the higher percentage of dry matter carried out to higher sugar yield in hydrolyzed. It was possible observed that products quality improved with a higher concentration of dry matter

Desenvolvimento e avaliação físico-química, sensorial e da estabilidade de ácido ascórbico de doce de leite com pimenta

The dulce de leche or milk candy is a food widely consumed in Brazil, which shows typical characteristics of taste, color, flavor and texture. The lady-finger red pepper is regularly present on the Brazilian people table as this product contains a pungent flavor favoring various spices; and it is also rich in ascorbic acid (vitamin C) which is an excellent antioxidant. This study aimed at developing a dulce de leche containing lady-finger red pepper, and to determine the composition of the product. Also, the ascorbic acid contents were quantified in products stored for different periods (0, 30 and 60 days). The product acceptance by consumers on the sensory characteristics was evaluated by means of hedonic scale for color, aroma, flavor and texture attributes. The composition of the product was in accordance with the legislation in force, and the ascorbic acid contents were practically stable during the storage, and the sensory analyses indicated that the red pepper-containing dulce de leche was well accepted.
