DNA barcoding is a powerful sequencing-based tool for the detection of fish species substitution. However, various cooking methods have the potential to reduce the quality and success of DNA sequencing. The objective of this study was to determine the effects of common cooking methods on DNA sequencing results with both full-length (655 bp) and mini-barcodes (208–226 bp), and to determine the optimal methodology to use for species identification of various fish products. Six types of fish (salmon, tuna, scad, pollock, swai and tilapia) were prepared in triplicate using the following methods: uncooked, baked, fried, broiled, acid-cooked, smoked and canned. DNA …

Transnational trade of ‘Seedless Kishu’ mandarins (Citrus kinokuni mukakukishu) would require them to be subjected to a suitable phytosanitary treatment. Irradiation is used as an effective treatment for many fruit, but the effect on quality of kishu mandarins is unknown. ‘Seedless Kishu’ mandarins were treated with gamma irradiation (150, 400, and 1000 Gy) and stored for three weeks at 6 °C and then for one week at 20 °C. Irradiation at 400 and 1000 Gy promoted browning of the calyx end and fungal infection. Irradiation caused immediate reductions in pulp firmness, vitamin E, individual sugars and carotenoids but …
