RESUMEN
This research involved the selection of suitable tomato products from amongst the puree, paste and powder for manufacture of tomato flavoured paneer. Paneer was prepared from milk standardized to 3% fat and 8.5% MSNF. The first part of the study was conducted to select the optimum level of tomato puree, paste and powder. From amongst different rate of addition (w/w of milk) of tomato products studied viz. 7.5, 10, 12.5 and 15% in case of puree and paste and 4, 5, 6 and 7% in case of powder, it was found that samples containing puree, paste and powder @ 10, 10 and 5 % were liked the most. In the next part of the study three batches of paneer viz. T1, T2 and T3 were prepared in which tomato puree, paste and powder were incorporated at 10, 10 and 5% respectively. Control (C) paneer was prepared from standardized milk. It was found that the fat, FDM and pH of T1, T2 and T3 were significantly (P<0.05) lower than that of C, whereas moisture content of T1, T2 and T3 were significantly (P<0.05) higher than C. The recovery of fat, protein and TS in T1, T2 and T3 was significantly (P<0.05) lower than C, while no significant (P>0.05) difference was observed in yield of paneer. All the textural properties viz. hardness, springiness, cohesiveness, chewiness and gumminess of samples containing tomato products were significantly (P<0.05) lower compared to control. The overall acceptability score of T1 was significantly (P<0.05) higher than that of T2 and T3 but was significantly (P<0.05) lower compared to C. The Vitamin C, total dietary fiber and antioxidant capacity of T1 was significantly (P<0.05) higher compared to C. Hence, it was concluded that good quality tomato flavoured paneer can be prepared incorporating tomato puree @ 10% w/w of milk with better functional properties compared to control.
RESUMEN
Three varieties of cassava bread were analyzed by proximal analysis and biochemical methods. The content of protein, fat, carbohydrate, ash, crude fiber and dietary fiber (DF) differed significantly between each sample (p< 0.05). The cassava variety "Puerto Ayacucho" showed a higher content of insoluble DF (4.7%), soluble DF (1.6%), total DF (6.3%) and pectin (0.61%)) in comparison with the varieties of "Rio Chico" and "Caripito". Soluble DF retains significant amounts of water in the digestive tract, and this fact, combined with its reported effect of lowering human serum cholesterol its low moisture plus a high carbohydrate content confirm the suitability of this bread as an important nutritional food.
Tres variedades de casabe de yuca fueron analizados mediante el análisis proximal y métodos bioquímicos. El contenido de proteínas, grasas, hidratos de carbono, ceniza, fibra cruda y fibra dietética (FD) difieren significativamente entre cada muestra (p <0,05). La variedad de casabe "Puerto Ayacucho" mostró un mayor contenido de FD insoluble (4,7%), FD soluble (1,6%), FD total (6,3%) y pectina (0,61%)) en comparación con las variedades de "Rió Chico" y "Caripito ". FD soluble retiene grandes cantidades de agua en el tracto digestivo, y este hecho, combinado con su efecto ya reportado de bajar el colesterol del suero humano, así como el casabe de contener un bajo contenido de humedad aunado a un alto contenido de hidratos de carbono; confirma la idoneidad del mismo, como un importante alimento nutricional.
