    Notes: SUMMARY— Gamma irradiation (0.4 Mrad) of Bombay duck (Havpodon nehereus) fillets sealed in polyethylene bags brought about alterations in the bacterial flora during storage at 10–12°C. Micrococcus, Pseudomondas, Ackromobacter, Flavobacterium, Microbacterium, Bacillus, Alkaligenes, and Sarcina, which comprised the initial flora of Bombay duck, were predominated by Proteus, Bacillus, Aeromonas, Micro-cocci, and Neisseria in the spoiled samples after four days storage at 10–12°C. In contrast, absence of putrid odors in the irradiated samples stored at 10–12°C for 14 days may be attributed to the biochemically inactive nature of the predominating Micrococci.

    Notes: Optimum conditions of radiation dose (0.25 Mrad) and heat treatment (60°C for 10 min) have been studied for maximum precipitation of the fibrillar proteins of Bombay duck (Harpodon nehereus). This combination treatment resulted in 83% precipitability of the fibrillar protein fraction (extracted in 0.01 m phosphate buffer containing 5% sodium chloride) without causing precipitation of the sarcoplasmic proteins (extracted in 0.01 m phosphate buffer, pH 7.5). Sarcoplasmic proteins denaturated by irradiation or heat treatment exhibited increased rate of tryptic hydrolysis and alterations in the pattern of Sephadex gel filtration and polyacrylamide gel electrophoresis. Susceptibility of the fibrillar proteins to trypsin was not changed.

    Notes: SUMMARY— The storage life of fresh, peeled and deveined tropical shrimps at 10—12°C is extended to 10—14 and 18—21 days with 0.15 and 0.25 Mrad, respectively, as against spoilage of unirradiated samples within 4 days. Blanching treatment (steaming for 4 min) with or without brine (3.0% NaCl) extends the storage life up to 30 days at lo—12°C. the former retaining the shell-fish flavor. However, the blanched products develop musty odor and slimy texture during storage; subjected to irradiation (0.15 Mrad) these are devoid of undesirable attributes and are acceptable for 60 and 130 days, respectively, at 10—1°C and 2—4°C. Bacterial counts exceeding 108/g and high levels of TMAN and TVBN concur with spoilage of unirradiated shrimps. In contrast, low levels of TMAN and TVBN, despite high TBC, corroborate with high acceptability of radiation processed shrimps. In blanched as well as in blanched and irradiated shrimps TBC, TMAN and TVBN are low. Samples subjected to blanching only have low acceptability as against the improvement in quality by irradiation. These alterations in storage property have been discussed in the light of shifts in microflora.

    Notes: The effect of frozen storage and different glazes on the denaturation of fish proteins was studied. The solubility of proteins was affected less when glazes were used. The denaturation of proteins was restricted to the actomyosin fraction of proteins; the sarcoplasmic fraction remained unchanged. The total actomyosin denaturation was not closely related with either the decrease in apyrase activity of the muscle brei or with the contractility of the muscle fiber.
