“…According to Back et al [34], the GSI of female squid collected from the Southeast Sea during the same period as this study was higher than the GSI of male squid. In addition, the female gonads contained around three times as much lipid as the male gonads [35]. Considering these differences in GSI and lipid content between the two sexes, it is believed that much of the total OC burden in female squid is redistributed to the gonad, where it accumulates, and so OC concentrations are lower in female than in male squid.…”

In this study we investigated the current contamination status and accumulation features of POPs in Korean offshore waters using Japanese common squid as a biomonitoring organism. Concentrations of organochlorine compounds (OCs), such as polychlorinated biphenyls (PCBs), dichlorodiphenyl trichloroethane and its metabolites (DDTs), chlordane compounds (CHLs), and hexachlorocyclohexanes (HCHs) were determined in different organs of squid of both sexes and of various sizes caught in the offshore waters of southeast Korea in July and October, 2005. Most of the compounds showed their highest concentrations in liver among the organs analyzed. The concentrations of PCBs, DDTs, CHLs and HCHs in liver were in the ranges of 116-206 ng/g (mean: 146), 158-325 ng/g (238), 20.6-37.3 ng/g (28.2), and 1.68-12.3 ng/g (7.79) on a dry weight basis, respectively. There was no relationship between squid size and OC concentrations, while the levels of all of the compounds were significantly correlated with lipid content. Due to its relatively high lipid content, the concentration of OCs in squid liver was higher than other organs of the squid. Therefore, OCs in female squid may be redistributed from the liver to the gonad. These results showed that male squid liver is a useful organ for monitoring OCs in Korean offshore waters, regardless of its size.

We prepared a long-arm octopus Jangjorim prototype (LOJP) by optimizing the ratio of ingredients for seasoning and establishing heat sterilization parameters. The optimal amounts of purified water (2.9–56.6%, A), starch syrup (0.3–37.8%, B), and soy sauce (25.5–71.5%, C) for the production of seasoning soy sauce were obtained using response surface analysis. The LOJP was prepared by combining A, B, and C under the optimal conditions and evaluated for consumer preferences and physicochemical, nutritional, and microbiological properties and compared with Korea’s legal management standards for geriatric nutrition. The hardness of the LOJP produced using the optimal mixing ratio of purified water (51.2%, 154.0 g), starch syrup (29.3%, 308.0 g), and soy sauce (19.5%, 256.9 g) was 36.7 × 1000 N/m2. This value was lower than the hardness of raw octopus (2153.6 × 1000 N/m2) by 2116.9 × 1000 N/m2. It received the highest score (8.7) in the preference evaluation of older consumers. The LOJP was classified as level 2, allowing consumption through the gums of elderly consumers per Korea’s food standards for the elderly. The LOJP was the product highly preferred by elderly consumers with chewing disorders due to its ease of intake and nutritional content.

Menopause increases the onset of hypertension and heart disease. Whereas it increases the blood LDL-cholesterol, triglyceride and total-cholesterol levels, the HDL-cholesterol concentration is reduced. Accordingly, we examined the effect of internal organs of Todarodes pacificus (IOT) on improvement in blood flow ability and changes in serum lipid content by using ovariectomized rats. For this study, the following four groups of 9-week-old Sprague-Dawley strain female rats were evaluated over 6 weeks: normal rats (SHAM), ovariectomized rats (CON) and ovariectomized rats that were treated with IOT extracts. Ovary removal promoted platelet aggregability. However, IOT administration in the CON group after ovary excision resulted in a hinderance of coherence. The blood vessel passing time of ovariectomized rats was slower than the SHAM group. But the blood flow ability, which was slowed down for ovary removal, was improved by IOT administration. Serum triglyceride levels were significantly reduced by IOT administration. Moreover, blood HDL-cholesterol levels were reduced by ovary removal. However, IOT administration after ovary excision significantly increase HDL-cholesterol levels. The biological activity of IOT could be confirmed from these results. Moreover, IOT can be used in the development of functional foods which are meant to improve blood circulation and anti-platelet aggregation function. According to these results, we could know that IOT improved blood flow and anti-platelet aggregation. Therefore, it is expected that IOT can be used for the development of functional foods.
