Physicochemical and functional properties of albumin fractions from barley and rye seed protein isolate

Kazumi Ninomiya, Miho Otsuka, Norikazu Ogino, Yutaka Aoyama et autres

Barley and rye are major cereals worldwide and contain proteinaceous α-amylase inhibitors for biological defence against insects. Inhibiting mammalian α-amylase could potentially be a promising functional food characteristic for suppressing postprandial blood glucose levels. This study examined in vitro mammalian α-amylase inhibitory …

Effects of Cereal-Derived Proteins and Peptides on Blood Glucose Levels

Kazumi Ninomiya, Yusuke Yamaguchi, Hitomi Kumagaı

Some cereal proteins and their digestive peptides exhibit the potential to regulate blood glucose levels, which is important for the management of diabetes and its complications. Proteins in common grains, such as wheat and buckwheat, and in legumes, such as kidney beans …

Analysis of Short‐ and Long‐Term Two‐Mode Retrogradation of Corn Starch During Refrigerated Storage

Kazumi Ninomiya, Nozomi Ozawa, Yo Okawa, Yusuke Yamaguchi et autres

ABSTRACT Background and Objectives Starchy foods stored at low temperatures for long periods undergo hardening due to starch retrogradation (crystallization). However, a method for measuring the degree of starch retrogradation has not been sufficiently established yet. In this study, two modes of …

Lenthionine, a key flavour compound of shiitake mushrooms, prevents platelet aggregation by inhibiting αIIbβ3 activation

Shoichiro Shimada, Soichiro Mochizuki, Yuki Tanabe, Kyohei Yamada et autres

Cardiovascular diseases, which are frequently associated with thrombosis and platelet aggregation, are a significant global health concern. The inhibition of platelet aggregation is a crucial strategy for the prevention of thrombotic disorders. Our previous studies have demonstrated that lenthionine, a cyclic polysulphur …

Comparative analysis of isothiocyanates in eight cruciferous vegetables and evaluation of the hepatoprotective effects of 4-(methylsulfinyl)-3-butenyl isothiocyanate (sulforaphene) from daikon radish ( Raphanus sativus L.) sprouts

Yusuke Yamaguchi, Mikio Sugiki, Motomi Shimizu, Kazuki Ogawa et autres

-transferase (GST) in the liver, whereas the crude extract of broccoli sprouts showed limited upregulation. This study highlights that daikon radish sprouts and sulforaphene have the potential to serve as functional food materials with hepatoprotective effects. Furthermore, daikon radish sprouts may exhibit …

Anti-melanoma effects of S-allyl-L-cystine sulfoxide (ACSO/alliin) from garlic in C57BL/6J mice

Yusuke Yamaguchi, Toshiki Ando, Tomoaki Yazaki, Hitomi Kumagaı

Certain foods modify the risk of developing melanoma. Various garlic compounds, including odor precursors and their derivatives, inhibit tumor growth; thus, garlic could protect against melanoma. However, it is unclear if S-allyl-L-cystine sulfoxide (ACSO/alliin), which is the most abundant (>10 mg/g) odor …

Differences and similarities of albumins from japonica rice bran, japonica, indica, and javanica rice endosperm in the suppressive effect of postprandial blood glucose elevation

Rio Ogawa, Chiaki Sugimoto, Aya Hamada, Kazumi Ninomiya et autres

Abstract Suppression of rapid increase in blood glucose level using food components can prevent diabetes. To use functional food components from natural resources, information regarding the plant varieties and plant parts where the component exists is important for the effective extraction and …

Physicochemical properties of buckwheat albumin

Rio Ogawa, Hitomi Kumagaı, Sébastien Paul

For prevention of diabetes mellitus, it is effective to suppress or retard the increase in postprandial blood glucose level. We have already shown that buckwheat albumin inhibits α-amylase and suppresses postprandial hyperglycaemia even after the hydrolysis by digestive enzymes. However, there is …
