Abstract

Protein powder is one of the nutritional supplements most commonly consumed, by professional and amateur athletes and also by those taking exercise for non-sporting purposes. During its manufacture, the thermal treatment involved can reduce the nutritional value of the product, an aspect that has received little research attention. In this study15 samples of protein powder were analysed by qualitatively and quantitatively for presence of claimed components such as protein, carbohydrate and energy. After analysis it was found that the quantity of protein were less as compared to claimed, were as quantity of carbohydrate showed variation as compared to claimed and variation in the calories content was seen in samples S2, S4, S6, S7, S8, S10 and S12 have high energy level (/kcal) than the mentioned claimed on sachet.
