Table 4. Comparison of biotin content in fish and shells using different extraction methods

Samples		Biotin (μg/100 g)¹⁾
Samples		Non-treated	Pepsin-assisted
Fish and shells	Mackerel	1.684±0.318^b2)	2.130±0.023^a
	Salmon	0.932±0.004^a	0.965±0.033^a
	Hair tail	0.604±0.010^b	0.670±0.014^a
	Giant octopus	0.610±0.028^b	0.723±0.010^a
	Oyster	0.868±0.037^a	0.883±0.061^a
	Cockle	1.163±0.035^b	1.610±0.029^a

All values are mean±SD (n=3).
Different superscript letters (^a,b) within a row of each same food under biotin are significantly different by Duncan’s multiple range test at p<0.05.
