Survey of the properties of waxed duplex cartons used in frozen shrimp industry

Waxed duplex cartons collected from different prawn freezing factories were evaluated for their physico-chemical properties such as bursting strength, puncture resistance, water proofness, tearing, strength, tensile strength, elongation, moisture content, thickness, weight of the carton, dimension, wax content and saponifiable matter. The results are discussed from the point of view of formulation of standards for this most widely employed packaging material for frozen fishery products in the country.

Quality control in the Indian fish processing industry

Quality control is defined as the continuing assessment of a current operation. It is usually the responsibility of an individual or a department directly responsible to the management. In the case of fish and fishery products, quality control includes all the steps taken to protect the quality of the material since catch until it reaches the consumer.

A review on oil sardine 3. Oil and meal industry

The author reviews the advances in the oil and meal industries related to the oil sardine fishery (Sardinella longiceps) since the 1920s. Data on the production of by-produced produced in Kerala over the period 1964- 69 are tabulated. Details of the properties of the commercial oil are given, and the values compared to those for other similar oils. The use of oil sardine for industrial purposes - the oil has been used to cure leather, temper metals and as fungicides or insecticides - and the production of fish meal and fish protein concentrate is considered.

Utilization of the fish waste self-brine of fish curing industry as farm fertilizer

Large quantities of self-brine accumulating in curing tanks during the process of commercial fish salting is mostly wasted at present. This liquor exuded from the fish during the process of salting contains considerable amounts of soluble proteins and minerals. Due to the presence of organic matter the self-brine quickly putrefies causing nauseating smell. This renders the whole surroundings insanitary and often leads to health hazards to neighboring localities. Any economic method of utilising this waste brine and converting it into some useful product will be a tangible help to the fish curing industry. Hence, a method is given for converting this waste self-brine into a cheap and efficient fertilizer.
