Abstract:
Consumer survey for profiling the desirable product from jelly fish indicated that consumers liked to have a product containing jelly fish, e.t., fish ball or Pla-Yaw and 67 percent of the consumer liked to buy those jelly fish products. The objective of this study was to use inexpensive part of jelly fish for value added product. i.e., surimi-jelly fish mixed ball. Varying ratio of the surimi : jelly fish at 80 : 20, 75 : 25, 70 : 30 and 65 : 35, it was found that sensory evaluation scores, i.e., appearance, taste, texture and overall acceptability of the samples were significantly different (P <_0.05). The sensory evaluation scores of sample with surimi : jelly fish 75 : 25 were higher than the others. Eight percent tapioca starch increased scores for texture, overall acceptability, gel-strength and elasticity (P<_0.05). Shelf-life of jelly-fish balls made from surimi : jelly fish at the ration of 75 : 25 with 8 percent tapioca starch was studied by packing in PA/LDPE bags under air, modified atmosphere with 60 percent CO2 + 40 percent N2 and vacuum and stored at 4-6 deg C. It was found that products packed under modified atmosphere had shelf-life not less than 21 days with those packed under vacuum and air had shelf-life not less than 12, and 9 days, respectively. All products packed under different conditions were free from health hazard microorganisms. The ready to eat products gave in desirable characteristics as required by the consumers at the profiling stage. Results from the consumer test showed that the degree of acceptance of appearance. Elasticity, jelly fish texture, taste and overall acceptability were like moderately whilst the acceptance for cooking convenient was like very much.
