In this report, we investigated microbiologically the cause of the kerosene-like off-flavour in “surimi-based products” (chikuwa) kept at 10°C for 7 days. The results are as follows. From the kerosene-like off-flavoured “surimi-based products”, the appearance is the same as normal, while no swelling, softening, or discoloration was recognized. We isolated bacteria and yeasts, but molds could not be isolated. As the result of a kerosene-like off-flavour reproduction test using these isolates, all yeasts but not all bacteria produced this odor. Among the raw materials (15 kinds) for “surimi-based products”, only natural food preservative produc-ed this odor. Yeast that produced a kerosene-like off-flavour was identified as Debaryomyces hansenii, and the component of this odor was confirmed by GC-MS to be styrene.

Octopus melanin obtained from ink bags of Octopus vulgaris CUVIER was found to inhibit gastric secretion in rats in the same way as that from Ommastrephes bartrami LESUEL. The molecular weight of this melanin fraction (which has an indole skeleton) was estimated to be over 200000 by gel filtration on Sephadex G-200, and the Octopus melanin fraction (Fr. OM) released several kinds of proteins in the presence of SDS. The chemical composition of Fr. OM was melanin pigment 79%, protein 17.5% and sugar 1.7%, so Fr. OM was considered to be a melanoprotein. Fr. OM significantly reduced gastric secretion in rats at the dose of 1 mg/kg, i.p., and also prevented both ulcer formation in pylorusligated rats and aspirin-induced ulcer.
