    Prevailing challenges in Processing of Fermented Fisheryproduct ‘Shidal’ in Tripura, India and Solutions
    (Society of Fisheries Technologists (India), 2022-02-02) Uchoi, Devananda; Kishore, Pankaj; Kumar, Anuj; Nadella,Ranjit Kumar; Satyen Kumar Panda; A. A. Zynudheen
    Shidal is a traditionally bio-processed fermented fishery product produced from minor carps particularly, Puntius sp. It plays a significant role in the diet of North-Eastern people in India. In Tripura and other North-Eastern states, shidal is consumed as health food by general public. Hygienic processing of shidal has received more attention in recent years as the number of consumers and demand for superior quality shidal is increasing. The study was undertaken in 14 dry fish markets from 4 districts of Tripura through market survey and personal interview to identify key challenges associated with processing of shidal. Data was collected from a total of 50 randomly selected respondents from commercial shidal processors (n=10), household shidal processors (n=10), retailers (n=20) and local vendors (n=10). It was found that for commercial shidal processors, supply of poor quality raw materials and lack of skilled workers were the major issues. In case of household processors, lack of adequate infrastructure and breakage of earthen pots were the main issues; whereas, for retailers and street vendors lack of proper packaging system was the main issue. Thus, the challenges in shidal processing were recorded and solutions are suggested which could help the policy makers to recommend guidelines for hygienic handling and processing of shidal.

    Quality Evaluation of Spray-Dried Shell Protein Derived from Flower Tail Shrimp (Metapenaeus dobsoni)
    (Society of Fisheries Technologists (India), 2022-08-02) Lakshmi Seethl; A. Jeyakumari; U. Parvathy; A. A. Zynudheen
    During shrimp processing, large quantities of waste are generated in the form of head and carapace, which comprises a fair amount of biomolecules like chitin, protein, fat, minerals, astaxanthin, etc. The current practice for the utilization of shrimp waste is the extraction of chitin and chitosan. However, during production of chitin, protein present in the shells are not utilized properly and it can be recovered mechanically. In the present study, the shrimp shell protein was extracted from Metapenaeus dobsoni  by mechanical process and spray dried. The proximate composition and chemical quality parameters (TVBN, TMAN, PV, FFA, and TBA) of Shrimp Shell, Shrimp Shell Protein Solution (SSPS), and Spray-dried Shrimp Shell Protein Powder (SSPP) were evaluated. Functional properties such as foaming capacity, Foam stability, Water absorption capacity, Oil absorption capacity, Hygroscopicity, and Flow properties of SSPP were also investigated.  The TVBN, TMAN, PV, FFA, and TBA values of Shrimp Shell, SSPS, and SSPP were found to be within acceptable limits. Higher protein content was found in SSPP (64.27±0.56%) than in SSPS (52.35±1.04%), the result suggested that SSPP can be incorporated into food as a good source of protein for human consumption.

    Studies on Mass and Nutrients Balance During EnzymaticHydrolysis of Cuttlefish Skin Waste
    (Society of Fisheries Technologists (India), 2022-05-05) K. Elavarasan; M. D. Hanjabam; C. S. Tejpal; K. Sathish Kumar; A. A. Zynudheen
    Processed cuttlefish is one of the major seafood export commodities of India. Approximately 35% of raw material is converted into by-products during processing of cuttlefish. The cuttlefish skin waste (CSW) accounted to roughly 9% of the raw material and 28% of the by-products generated. In the present investigation, five different proteases namely alcalase, protease from Streptomyces griesus, protamex, papain and bromelain were screened for hydrolysis efficiency on CSW and found to produce soluble content of 80.65, 79.85, 73.47, 66.41 and 67.71%, respectively. Though the bacterial proteases were relatively more efficient in terms of soluble production based on the cost factor, papain was used for studying the mass and nutrients balance during the process of production than the plant proteases of cuttlefish skin protein hydrolysates. Papain enzyme was useful in converting the CSW in to two protein rich products namely water soluble protein hydrolysates and insoluble protein hydrolysates with 82.86 and 71.25% crude protein, respectively. The data presented would be useful for setting up industries for protein hydrolysates production from cuttlefish skin waste, which is abundantly available in India.
