- PublicationAnalysis of Cadmium Content in Cephalopod for Exporting(University of the Thai Chamber of Commerce, 2006)
; University of the Thai Chamber of Commerce. School of Science and TechnologyCadmium analysis in exporting cephalopods was done in 3 types of raw cephalopods namely squid, cuttle fish and octopus. Experiments were divided into 3 section,Section 1 analysed cadmium content in cephalopods from 5 handling fisheries zone in the Gulf of Thailand and Andaman Sea. Sample of cephalopods was taken during three stages from January to September 2004. The results showed that handling zone effected on the cadmium content in cephalopods (p<0.05) and it was found that Cephalopods from zone 4 ( Surathani, Nakornsrithumrat , Pattalung , Songkhla , Pattani and Naratiwat Provinces) had the highest cadmium content. Handling times does not effect on the cadmium content in cuttle fish (p>0.05) and it was found that squid and octopus were handlinged between July - September 2004 had the higher cadmium than the other handling times. Section 2 analysed cadmium content in different parts of squid, cuttle fish and octopus. The result showed that funnel and funnel locking cartilage of squid and cuttle fish had the higher cadmium than eye head and tentacles (p<0.05) and it was found that the body of octopus had the higher cadmium than the tentacle (p<0.05). Section 3 studied the cleaning procedure of cuttle fish prior to freezing process. The result showed no significant difference (p>0.05) for cleaning procedure by soaking in water or running water, niether between using water at 10 and 20 degree celcius , nor the different cleaning times at 1 3 and 5 minutes,but it was found that the trend of cadmium content drop when the cleaning times increased.10 453
