β-Cryptoxanthin is a type of carotenoid that contributes to the maintenance and improvement of human health. However, it is sensitive to heat during cooking and food processing. Furthermore, like other carotenoids, β-cryptoxanthin is also highly hydrophobic and does not readily solubilize in the gastrointestinal tract. This property results in its low bioaccessibility, and considerable knowledge has been accumulated on improving the bioavailability of β-cryptoxanthin. In this study, we evaluated the effects of different processing methods on the residual amount of β-cryptoxanthin in kumquats. The results showed that preparation of kumquat paste contained more β-cryptoxanthin than its puree. Next, when the paste was mixed with fermented <i>Aspergillus oryzae</i> milk, the β-cryptoxanthin content did not change. A pasteurization study of the kumquat paste mixed with the fermented milk showed that β-cryptoxanthin was more stable at 65 °C than at 85 °C. In addition, to improve the bioaccessibility of β-cryptoxanthin, a mixture of the fermented milk and kumquat-derived β-cryptoxanthin was evaluated using a human intestinal epithelial Caco-2 cell model. The results showed that β-cryptoxanthin in the mixture permeated the membrane 14 times more than β-cryptoxanthin alone.

The chemical composition of muscles from Japanese eels cultured in hot-spring water was determined and compared with that of eels cultured in well water. The proximate composition did not differ significantly between the culture conditions, but the hepatosomatic indices of the hot-spring water eels were significantly higher than those of the well water eels. Amino acid levels were higher in the hot-spring water eels, and the carnosine content of the hot-spring eels was lower than that of the controls. Our results suggest that hot-spring water is a promising medium for eel culture, and its use may bring energy cost savings.

Inflammatory activity and hypoxia in atherosclerotic plaques are associated with plaque instability and thrombotic complications. Recent studies show that vascular cell metabolism affects atherogenesis and thrombogenicity. This study aimed to identify the metabolites in macrophage-rich unstable plaques that modulate atherogenesis and serve as potential markers of plaque instability. Atherosclerotic plaques were induced by balloon injury in the iliofemoral arteries of rabbits fed on a conventional or 0.5% cholesterol diet. At 3 months post-balloon injury, the arteries and cardiac tissues were subjected to histological, quantitative real-time polymerase chain reaction, and metabolomic analyses. The identified metabolite-related proteins were immunohistochemically analyzed in stable and unstable plaques from human coronary arteries. The factors modulating the identified metabolites were examined in macrophages derived from human peripheral blood mononuclear cells. Metabolomic analysis revealed that choline and guanine levels in macrophage-rich arteries were upregulated compared with those in non-injured arteries and cardiac tissues. Vascular choline levels, but not guanine levels, were positively correlated with the areas immunopositive for macrophages and tumor necrosis factor (TNF)-α and matrix metalloproteinase (MMP) 9 mRNA levels in injured arteries. In human coronary arteries, choline transporter-like protein (CTL) 1 was mainly localized to macrophages within plaques. The area that was immunopositive for CTL1 in unstable plaques was significantly higher than that in stable plaques. Intracellular choline levels were upregulated upon stimulation with TNF-α but were downregulated under hypoxia in cultured macrophages. Administration of choline upregulated the expression of TNF-α and CTL1 mRNA in cultured macrophages. The transfection of CTL1 small interfering RNA decreased CTL1, TNF-α, and MMP9 mRNA levels in cultured macrophages. These results suggest that choline metabolism is altered in macrophage-rich atherosclerotic lesions and unstable plaques. Thus, CTL1 may be potential markers of plaque instability.
