Abstract:
The study was carried out for utilization of rainy season guava fruits cv. Shweta for preparation of foam mat dried guava fruit powder. The conversion of guava fruit pulp into foam was optimized by whipping the pulp after addition of glycerol monostearate (GMS) and drying the resultant foam in dehydrator (60±5 °C) to constant moisture content. Drying of guava fruit pulp foam by using 2% GMS results in 14.74 per cent powder yield and was found the most appropriate with respect to desired foaming properties (foam density, foam expansion and foam stability), drying time and powder yield. With the increase in the foaming agent concentration, the foam density decreases significantly however, the percentage of foam expansion was increased. In comparison to foam density, the guava fruit pulp exhibited higher foam expansion of 19.42 per cent with 2% GMS whereas, (control) without foaming agents exhibited maximum foam density. Thus, the guava fruit pulp can be utilized for preparation of self-stable powder using foam mat drying technique for further preparation of value-added products.
