The present thesis entitled "Development and evaluation of nectar and crush from Guava-Mango blends" was carried out with the objectives to standardize appropriate combination of guava-mango blends for preparation of nectar and crush and also to evaluate quality of blended products during storage. Data show that guava and mango fruit had fruit weight (95 and 320 g), pulp weight (848 and 720 g/kg fruit) and yield of pulp (84.8% and 72.0%), respectively. Chemical constituents of guava and mango fruits such as TSS, total sugars, reducing sugars and acidity were found to be (10.60and 18.20%), (6.84 and 12.60%), (3.25 and 6.27%) and (0.36 and 0.46%), whereas pH, ascorbic acid, total carotenoids, pectin and total phenols were analyzedto be (5.06 and 4.63), (158 and 62 mg/100 g), (N.D and 5.17 mg/100 g), (0.89 and 0.56%) and (3.21 and 58.67 mg/100 g), respectively. Total sugars, reducing sugars and acidity increased, whereas ascorbic acid, total carotenoids and total phenols decreased significantly in all the beverage blends during three months storage. The comparative study of all the beverages revealed that the beverage blends prepared with 20 guava : 80 mango pulp ratio were highly acceptable followed by 40 guava : 60 mango pulp and 0 guava : 100 mango pulp ratio (pure mango). Overall acceptability of all the beverages prepared from guava-mango blends decreased significantly with increase in storage duration. The cost of production was recorded maximum in beverages (nectar and crush) prepared with 0 guava : 100 mango (pure mango pulp) followed by 20 guava : 80 mango, 40 guava : 60 mango, 60 guava : 40 mango, 80 guava :20 mango and 100 guava : 0 mango (pure guava pulp) with a decreasing trend in their cost. |
