Preparation of Masmin: an improved method

An improved method for the preparation of Masmin the traditional smoked tuna of the Lakshadweep is described.

Preparation of edible powder from Jawla (Acetes sp.) prawns

Four methods were employed for the preparation of prawn (Acetes) powder in this study. The analytical characteristics and bacteriological quality of the edible powders are presented for each method.

Beverage preparation from fish hydrolysate

A method for the preparation of energy food incorporating fish hydrolysates, sugar, cocoa, malt extract etc. is described. The product has good consumer appeal. The preparation does not impart any bitter taste of the hydrolysate to the final product irrespective of the type of fish used for preparing the hydrolysate. It freely mixes with hot or cold milk and the resulting drink is adjudged to be very palatable.

Preparation of smoke cured fillets from oil sardine

A method of preparation of smoke cured fillets of oil sardine is described. Various procedural steps like brining, smoking, packaging etc. have been described and the shelf life assessed. Sodium propionate treatment is recommended to enhance storage life; BHA to control rancidity; and thermal treatment to overcome the insect infestation. The product has good consumer appeal.

Preparation and storage behaviour of fish protein biscuits

This paper deals with the investigations carried out on the preparation and storage characteristics of protein enriched biscuits (sweet and salt), incorporated with partially de-odourised fish protein concentrate. The product contains more than 20% protein and has storage life exceeding 6 months at room temperature (21°C to 32°C), in 400 gauge polythene bags.

Fast evolution of growth hormone receptor in primates and ruminants

Pituitary growth hormone (GH) evolves very slowly in most of mammals, but the evolutionary rates appear to have increased markedly on two occasions during the evolution of primates and ruminants. To investigate the evolutionary pattern of growth hormone receptor (GHR), we sequenced the extracellular domain of GHR genes from four primate species. Our results suggested that GHR in mammal also shows an episodic evolutionary pattern, which is consistent with that observed in pituitary growth hormone. Further analysis suggested that this pattern of rapid evolution observed in primates and ruminants is likely the result of coevolution between pituitary growth hormone and its receptor.

Preparation of mussel meat by drying

The paper describes a simple and cheap process for the preservation of mussel meat by drying. The method involves blanching the mussel meat shucked from purified live mussels in 5% boiling brine for 5 min followed by drying to moisture of 10 to 15%. The product stored in glass bottles or polythene bags suitably sealed, has a storage life of about six months after which the organoleptic qualities begin to deteriorate. No preservative is used at any stage of processing and the yield of the product is approximately 20%. The major type of spoilage during storage is brown discoloration. Spoilage due to insect infestation is also common unless packed properly.

Preparation and storage of cutlet from low-priced fish

Cutlets have been prepared from the minces of lizard fish (Saurida tumbil), threadfin bream (Nemipterus japonicus), jew fish (Johnius dussumieri) and miscellaneous fish. The storage characteristics of cutlet (both raw and flash fried) at 4°C, -8°C and -20°C were studied. Cutlets prepared from the minced lizard fish showed the highest acceptability. Flash fried cutlets were found to be superior in quality compared to raw cutlets. The raw cutlet had storage life of 6 days, 11 weeks and 19 weeks at 4°C, -8°C and -20°C respectively and flash fried cutlets had a shelf life of 22 weeks at -20°C.

Preparation of lime from mussel shelf waste

A process is described for the utilisation of mussel shell wastes by their conversion into lime, which may be used for white washing and plastering.

Suitability of tuna red meat for preparation of wafers

Studies to find out the suitability of tuna red meat for preparation of wafers have indicated that the red meat as such is not a good raw material for the production of wafers. The wafers obtained had poor organoleptic quality and characteristic tuna red meat flavour unacceptable to consumers. Attempts to prepare the wafers with the red meat mixed with the meat of barracuda in varying proportions showed that the mixture of red meat and barracuda meat in the ratio 1:3 gives a product having excellent physical properties and good swelling characteristics. The overall organoleptic quality of these wafers was very much comparable to the wafers produced from other quality fish. Increasing the proportion of red meat not only affects the overall appearance of the product but a1so imparts the red meat taste to the product.

Quality of fish preparation served in catering establishments of Bombay

The results of the study carried out on the quality of fish preparations served in catering establishments of Bombay revealed that there is no serious potential health hazard to the consumer. Pathogens like Salmonella and Clostridium per were found to be absent. Based on organoleptic, biochemical and bacteriological parameters the quality of fish curry was better than that of fish fry. Overall quality of samples from grade I establishments was better in comparison with grade II and III. However, a few samples of poor quality were also observed in grade I. Extraneous matter like hair and dead housefly were observed in a few samples from grade III indicating poor handling practices. The importance of good hygiene and sanitary practices in catering establishments is discussed.

Preparation and keeping quality of hot smoked mackerel

A method has been standardised for the production of smoke cured mackerel by dry salting in the ratio of 1:8 salt to fish followed by smoking in a traditional smoke chamber at 70±5°C for 5h. The smoke was generated by burning moist coconut husk and saw dust. The product obtained by this method had shelf-lives of 105, 95 and 6 days in chilled storage (0 to 2°C) refrigerated storage (10±2°C) and at room temperature (29±2°C) respectively.

Preparation and characterization of three monoclonal antibodies against HIV-1 p24 capsid protein

HIV4 p24 detection provides a means to aid the early diagnosis of HIV-1 infection, track the progression of disease and assess the efficacy of antiretroviral therapy. In the present study, three monoclonal antibodies (mAbs) p3JB9, p5F1 and p6F4 against HI

Preparation of mussel marinade

A simple and cheap process for the preservation of mussel meat by marinading is described. The method involves blanching the mussel meat shucked from depurated live mussels in 3% boiling sodium chloride solution for 5 min followed by preserving it in a solution containing 3% acetic acid and 3% sodium chloride. The product stored in closed glass jars has a storage life of approximately 16 weeks at room temperature (23-30°C), after which the quality began to deteriorate. Texture of the meat is least affected and closely resembles that of the fresh meat.
