Development of Protein Rich Flavored Bar

Abstract

Abstract: The present study entitled “Development of protein rich flavoured bar” was conducted with the objective to develop protein rich flavoured bar using different ingredients, to assess the sensory accessibility, determine the nutritional composition and cost of developed protein bar. Protein rich flavoured bar were prepared by using three treatments i.e. T1 (dates 50g, oats 10g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 5g, cocoa powder 10g), T2 (dates 45g, oats 8g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 12g, guava flavour 10g) and T3 (dates 40g, oats 13g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 12g, orange flavour 10g). Organoleptic evaluation of the prepared product in relation to sensory attributes was carried out using the nine point hedonic scale score card by Srilaksmi (2015). The nutrient content of the value added food products were calculated with the help of food composition table given by Gopalan et al., (2011). The cost of individual raw ingredients used in the preparation of the food product as the prevailing market price. All treatments were replicated four times and the data obtained during investigation were statistically analyzed by using analysis of variance (ANOVA) and critical difference (C.D.) techniques. On the basis of sensory acceptability it was found that T1 was scored highest in terms of colour and appearance, body and texture, flavour and taste and overall acceptability. As well as T1 shows significantly high in the nutritive value among all treatments regarding energy, protein, carbohydrates, fat, fibre, calcium and iron. The cost of the protein rich flavoured bar per 100g of dry ingredients at the prevailing cost of the raw materials was highest in T1 (Rs. 29.33) followed by T2 (Rs. 20.69) and T3 (Rs. 20.34). Dates are very good source of fibre, carbohydrate, protein and act as natural sweetener with no fat. As the bar is rich in protein, iron and other macronutrients, so it is majorly recommended for Protein-energy malnutrition (PEM), athletes and anemic patient. Daily 100g of dates intake helps to get all essential nutrients. Strictly restricted for Type-1 diabetic patients. Keywords: Protein, Nutrient content, organoleptic evaluation, nutrition bar, cost.
