Xanthan gum is a high molecular weight substance with potential in improving emulsions properties. The formulation composition was selected on Tween 80 ternary phase diagram and was modified by the addition of xanthan gum at different concentrations (0.0% – 1.0%). The main objective of this study was to determine the effect of xanthan gum on physicochemical and rheological properties of rice br...

A 42-d study with 384 Hy-line brown laying hens was conducted to assess the effects of dietary octacosanol supplementation on laying performance, egg quality and blood metabolites of laying hens. Hens were randomly allocated into 4 dietary groups of 8 cages each, which were fed basal diet supplemented with 0 (Control), 9 (OCT9), 18 (OCT18), and 27 (OCT27) mg/kg diet of octacosanol isolated from...

To make a good use of rice bran that has been treated as a kind of industrial waste, we have tried to ferment the rice bran by typical microorganisms such as yeast, and to extract ingredients with antioxidative activity. The antioxidative activity was estimated as a SOD-like activity. The SODlike activities of the rice bran extracts after fermentation by using ESR spectroscopy by baker's yeast ...

AIMS This study aimed to determine the effect of a cell-free supernatant of Lactobacillus paracasei ATCC 27092 with and without rice bran extract (RBE) on Salmonella Typhimurium 14028s growth, and to identify a metabolite profile with antimicrobial functions. METHODS AND RESULTS Supernatant was collected from overnight cultures of L. paracasei incubated in the presence (LP+RBE) or absence (LP...

Fermented brown rice and rice bran with Aspergillus oryzae (FBRA) is considered to have the potential to prevent chemically-induced carcinogenesis in multiple organs of rodents. In the present study, we evaluated the possible chemopreventive effects of FBRA against prostate tumorigenesis. Six-week-old male rats of the transgenic rat for adenocarcinoma of prostate (TRAP) strain were fed diets co...

This study aimed to evaluate the quality characteristics of Tteokgalbi with 1% (w/w) black rice bran only (T1), or with black rice bran and one of the following four types of organic acid: ascorbic acid (T2), citric acid (T3), tartaric acid (T4), or maleic acid (T5) as a substitute for caramel colorant. Tteokgalbi with only black rice bran showed the highest (p<0.05) values of moisture content ...

OBJECTIVE Rice Bran Oil (RBO) is extracted from the outer layer of rice. Little information is available regarding its safety. The present study was conducted to assess its safety in chicken embryo model. MATERIALS AND METHODS RBO was injected on day 4 of incubation of chickens. The tissues and serum samples were collected. Oxidative stress parameters in the liver, kidney and brain and bioche...

Squalene is a triterpene that is an intermediate in the cholesterol biosynthesis pathway. It was so named because of its occurrence in shark liver oil, which contains large quantities and is considered its richest source. However, it is widely distributed in nature, with reasonable amounts found in olive oil, palm oil, wheat-germ oil, amaranth oil, and rice bran oil. Squalene, the main componen...

Four new metabolites related to IAA (indole-3-acetic acid) were isolated from an aqueous methanol extract of rice bran and were elucidated by spectroscopic methods to be a pair of diastereomers of 5-O-β-D-glucopyranosyl 3,5-dihydroxy-2-indolinone-3-acetic acid (A-1 and A-2) and of 5-O-β-D-cellobiosyl 3,5-dihydroxy-2-indolinone-3-acetic acid (B-1 and B-2). Compound B-1 was also a diastereomer of...

Isolation of proteins from rice bran was studied, comparing alkaline- and carbohydrase-aided extraction. It was found that protein extractability could be effectively improved using carbohydrases (Viscozyme L and α-amylase), especially when mechanical force was incorporated. Then, rice bran protein hydrolysates (RBPH) were prepared at various degrees of hydrolysis (DH), and employed to stabiliz...
