Abstract
Studies on the spoilage of iced prawns and its assessment by objective tests were reported earlier (Velankar and Govindan, 1959). These studies revealed that considerable losses of 'extractives'such as the free amino-acids occur during storage of prawns in ice due to leaching. Work done in the U.S.A.(Collins et al., 1960) and in India (J.R. Iyengar et al., 1960) has also shown that water-soluble chemical compounds including those produced through spoilage leach out during storage in ice. In order to evaluate accurately the development of the spoilage products it is necessary to carry out the investigations on prawns held at 0 degree C., i.e., the melting point of ice , without contact with ice. The results of these studies carried out by us are reported in the present paper.
