The effect of soy isoflavones on the Maillard reaction (MR) was investigated. Model systems composed of the soy protein glycinin (10 mg mL(-1)) and fructose (40 mg mL(-1)) under basic pH (∼12) conditions were employed for testing the anti-glycative effect of the major antioxidant soy isoflavones (genistin and genistein at 10 μg mL(-1)) and a soy isoflavone-rich extract. The contents of total ph...

The different macroscopic properties of closely related isoflavones were associated with the occurrence intermolecular interactions and torsion angles in solid-state.

the Japanese have eaten since ancient times. It contains several biologically active components that may contribute individually or synergistically to the health benefit. As consumers in the world are becoming increasingly aware of the health benefits of soybean, attention has turned to the way to take soybeans that provide improved taste, functional characteristics, and health benefits. Many s...

This paper provides an update and comprehensive review of the analytical methods used for quantifying isoflavones and their metabolites in cow's milk. Isoflavones are secondary plant metabolites that are similar to 17 β-estradiol in chemical structure. They form one of the most common categories of phytoestrogens. Numerous health benefits have been attributed to isoflavones, but many of these c...

BACKGROUND The isoflavones daidzein and genistein occur naturally in most soyfoods, conjugated almost exclusively to sugars. Controversy exists regarding the extent of bioavailability of isoflavone glycosides, and the mechanism of intestinal absorption of isoflavones in humans is unclear. Evidence from intestinal perfusion and in vitro cell culture studies indicates that isoflavone glycosides a...

BACKGROUND Isoflavones, the most abundant phytoestrogens in soy foods, are structurally similar to 17beta-estradiol. Few studies have examined the nociception and stress hormone responses after consumption of soy isoflavones. METHODS In this study, ovariectomized (OVX) female Long-Evans rats were fed either an isoflavone-rich diet (Phyto-600) or an isoflavone-free diet (Phyto-free). We examin...

Introduction It has been recognized for several decades that the use of legumes in traditional eastern diets has played a significant role in the incidence and mortality of certain disease states. Soy beans and products containing soy possess unique phytochemicals known as isoflavones which are thought to exert many biological effects in the human body. Scientists have proposed that these uniqu...

This review assessed the efficacy of isoflavone supplements to reduce vasomotor symptoms in menopausal women by reviewing all published randomized controlled trials. Systematic literature searches were carried out in 70 databases. Randomized and placebo controlled studies were included if they investigated the treatment of isoflavone supplements derived from soy or red clover on vasomotor sympt...

Incidence rates of colorectal cancer are relatively low in Asian populations, in which soy foods are commonly consumed. Soybeans and soy foods are an almost exclusive source of isoflavone intake. In in vitro studies, isoflavones have been shown to have various anticarcinogenic properties such as inhibition of protein tyrosine phosphorylation, induction of apoptosis, antiangiogenesis, and inhibi...

Isoflavones are soy phytoestrogens that have been suggested to be anticarcinogenic. Our previous study in premenopausal women suggested that the mechanisms by which isoflavones exert cancer-preventive effects may involve modulation of estrogen metabolism away from production of potentially carcinogenic metabolites [16alpha-(OH) estrone, 4-(OH) estrone, and 4-(OH) estradiol] (X. Xu et al., Cance...
