Thwaites swamp cabbge (Ipomoea aquatica Forsk) and water mimosa (Neptunia oleracea Lour.) were collected during winter summer and rainy seasons from Phu Luang Mueang Loei and Chiang Khan District.

The results showed that cadmium accumulation in the highest content among all metals in water mimosa (Neptunia oleracea Lour.) in summer season from Phu Luang District (1.83±0.01 mg/kg). The second highest metal content was lead which has found in swamp cabbge (Ipomoea aquatica Forsk) in summer from Mueang Loei District (1.40±0.08 mg/kg). chromium showed the lowest content in Limnocharis flava (L.) Buch in winter from Mueang Loei District (0.47±0.04 mg/kg). The contents of chlorpyrifos and heavy metals were not exceed the legal limits set by International Standard Food and Ministry of Republic Health No.98 of Thailand except Ipomoea aquatica Forsk which collected in summer that showed the lead content higher than the legal limits.

For physical properties catfish Som-fug were 3.54±0.20 cm (width) 6.38±0.25 cm (length) 1.34±0.10 cm (height) and 2.50±1.4 g (weight) which is similar to that of brand C. Color analysis of un-fried catfish Som-fug showed light color that L* was 70.78±0.13 a* and b* were 5.06±0.53 and 11.50±0.31 respectively. Hue value was 74.42±0.25 value and chroma were 6.84±0.39 and 16.20±0.11 respectively. Som-fug from different brands were different in term of texture. The gumminess and chewiness values were significantly higher in brand B (p≤0.05) whereas the hardness and springiness did not differ significantly among the four different brands (p>0.05). For physio-chemical properties Som-fug produced from catfish had 1.70 % total acidity pH value was 4.50 and moisture content was 70.28% which was not different from that of brand B. However aw value did not differ among all of the Som-fug (p>0.05). The microbiological quality of the four Som-fug products analyses revealed the presence of Salmonella spp. Staphylococcus aureus Escherichia coli and mold count not more than standard (Thai Community Product Standard 471/2555) except brand B and C mold count was more than 100 CFU/g.
