Standardization of oxygen packing procedure of Chanos Chanos Seed
The present study was aimed at finding out the optimum conditioning method of C.chanos seed before packing, their optimum packing density, the effect of salinity, pH and oxygen pressure on their packing and the feasibility of using a sedative, tertiary butyl alcohol and chitosan as an absorbent in...

| 520 | 3 | |a The present study was aimed at finding out the optimum conditioning method of C.chanos seed before packing, their optimum packing density, the effect of salinity, pH and oxygen pressure on their packing and the feasibility of using a sedative, tertiary butyl alcohol and chitosan as an absorbent in removing toxic metabolites accumulated in the oxygen –packed containers. Specially designed air tight plastic containers were used for packing the seed. Of the seed packed after four treatments viz. control, congestion,, gut voiding and gut voiding plus congestion, the fourth treatment was the best with 3.25 fold increase in the duration of 100% survival compared to the control. From packing densities of 20,30,40 and 50 numbers per 50 ml water, a linear relationship between packing density in g/50 ml(X) and time of initial mortality in hours (Y) was established as Y=51.398-20.44X. No significant effect on the duration and survival of the seed was observed at different levels of salinity (0.ppt, 10ppt and 20pp), initial pH (6.5-7.5, 7.5-8.5 and 8.5-9.5) and oxygen pressure (oxygen at atmospheric pressure and at 0.2 kg/cm2 pressure). The use of tertiary butyl alcohol at 3.0 ppm and 3.5 ppm resulted in light and deep sedation of the seed respectively. It also increased the duration of 100% survival by 1.67 and 1.25 fold at the respective doses, compared to the control. The feasibility of using chitosan as an absorbent in oxygen packing of the seed was ruled out. | |
