SENSORY VARIATION ANALYSIS IN ICE CREAM MADE BY PALMYRA (BORASSUS FLABELLIFER) PULP WITH JAGGERY AND SELECTED SPICES

Abstract

Ice cream is a wholesome, nutritious frozen dairy product. Consumer acceptance of ice cream depends largely on its structure, textural quality, resistance to melting, nutritional composition and flavour. Incorporation of fruits and spices is one of the choices to increase consumer acceptance. The study was focused to develop a nutritional and flavour rich palmyra pulp ice cream with selected spices and jaggery. Eight sensory evaluation tests were carried out with 30 semi-trained panellist using 5 point hedonic scales. Initial sensory evaluation test results reveals pulp which is less bitter and added in overrun combination was selected for both natural and commercial pulp. Then 25% of pulp was selected for both type of pulp. By using the combination which is selected in previous sensory evaluation natural pulp ice cream and commercial pulp ice cream were developed. From that; natural pulp ice cream was preferred as best. Then for the selected ice cream, 125 ppm level of ginger and cinnamon oleoresins incorporated products were selected as best outputs. When comparing cinnamon natural pulp ice cream and ginger natural pulp ice cream, the first one was preferred because of bitterness masking property of ginger. At the end of sensory evaluations, jaggery added ginger flavoured natural palmyra ice cream was developed without adding artificial colouring and preservatives.
