- ItemTamarind fruit shell inhibits autolysis in mackerel and squid muscle(Cochin University of Science And Technology, 1998) Jayan, K.; Jose, J.; Raghunath, M.R.; Devadasan, K.Tamarind (Tamarindus indica) is a traditional culinary additive in India whose preservative effect is generally attributed to its tartaric acid acidulant. The shell of the tamarind fruit is usually discarded. Our report shows that the shell has a apowerful protease inhibitor which can retard autolysis in muscle of the Indian mackerel (Rastrelliger kanagurta) and Squid (Loligo duvauceli) which pose special problems to the fish processing technologist on account of their high rate of proteolysis and consequent early spoilage during postmortem storage. the powder of the dried fruit shells (Tamarind Fruit shell powder, TFSP) was incubated with tissue homogenates in buffered media. Tissue proteinases of mackerel and squid at acid as well as alkaline pH were inhibited to extents ranging from 41 to 100% in the presence of TFSP. The inhibitory principle in the shell powder could be extracted by buffers without losing its inhibitory activity. The inhibitory activity of extracts was only partially lost upon autoclaving the extracts indicating it was stable to some extent upon heat treatment. the broad range of inhibitory activity of tamarind fruit shell powder shows it has a preservative potential as a cheap and effective preservative for fish.
- ItemTrends in fish processing and quality assurance in Gujarat(Society of Fisheries Technologists (India), Cochin, 2003) Badonia, R.; Sen, A.; Devadasan, K.Gujarat is a leading state in marine fish production and export . Recent fish produclion of the state is over 0.65 million tonnes and export over Rs. 6000 million. The sLate is leading in export of fish such as squid. cuttlefish and surimi. Contrary to general perception. per capita fish consumption in the state is 7.77 kg.yr•1• double that of national average. Dried fish and lishmeal accounts for over 55% of the fish production. The freshwater aquaculture holds good prospects in the state. Processing practices, i mportant fish and fishery products, and major quality problems in the state. are discussed in this paper. Need for prawn culture, maketing of freshwater fishes, l ive fishes and shellfishes are highlighted. The paper stresses the need to realise the potential for internal marketing and export of d ried fish and byproducts.
- ItemValue addition of seafoods(Cochin University of Science and Technology, 2006) Devadasan, K.A large number of value added and diversified fish products both for export and internal market based on shrimp, lobster, squid, cuttlefish, bivalves, farmed fish and minced meat from low priced fish have been identified. A brief description of a few of such products, the technology for their production is readily available, is presented. The need to adhere to upgraded international quality yardsticks such as the EU Standards, requirements of HACCP and IS0-9000 series in fish processing establishments is stressed.
