ABSTRACT
The present study aims to find out the suitable storage condition of Orange-Fleshed Sweet potato (OFSP) beverage that will effectively retain the nutrient. Availability of OFSP may not necessarily translate tothe bioavailability of the vitamin if the vitamin source is not optimally processed and utilized. Information about the processing and utilization of conventional white and pinkish-fleshed sweet potato, There is a paucity of information on the appropriateprocessing methods of OFSP and possible storage condition of such beverage. The drinks were analyzed for Total soluble solid (TSS), pH and Viscosity on the zero-day before storage. The total soluble solids (Brix) of the drink was measured with a digital refractometer (DR-122 Code No: 44-905, London). Based on the results of this study OFSP drink may be utilized and best consumed when freshly produced if there is a need to store at ambient (27ºC) conditions, it should not exceed 48hrs. If OFSP drink is stored under refrigerated (4-8ºC) condition, it should not exceed 7days to retain its nutritive and sensory attributes
ABSTRACT
ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure better quality of the raw material. This study aimed to analyze the levels of soluble sugars during the maturation phase and assess the technological and productivity indexes of four irrigated sugarcane genotypes in the region of Rio Largo, Alagoas. The experiment was conducted in randomized blocks in a 4 x 2 x 5 factorial: four genotypes (RB92579, RB98710, RB99395 and RB961003), two stem portions (internodes 1-4 and internodes 5-8) and five seasons (82, 49, 25, 13 and 3 days before harvesting), each treatment with three replications. Internodes 1-4 showed the highest levels of reducing sugars, while the largest accumulation of sucrose and total soluble solids occurred in internodes 5-8. RB99395 genotype showed more stability in the sugar levels during sugarcane maturation, which can indicate early maturation and high agricultural yield.
