Tempeh is a traditional fermented soyfood native to Central Java, Indonesia; tempeh is prepared by salt-free aerobic fermentation using Rhizopus. Similar to miso, tempeh is also reported to be antioxygenic. In this study, we used a tempeh-like fermented soybean. First, soybean was incubated aerobically and then successively incubated anaerobically. Because the γ-amino butyric acid (GABA) content was increased remarkably, we named this tempeh GABA-tempeh. The contents of other free amino acids… 

Effect of fermentation time on the antioxidant activities of tempeh prepared from fermented soybean using Rhizopus oligosporus

The objective of this study was to evaluate the effect of fermentation time on the antioxidant activity of tempeh, a fermented product from soybean. Rhizopus oligosporus was used to ferment soybean

Tempeh extract reduces cellular ROS levels and upregulates the expression of antioxidant enzymes

Tempeh is an Indonesian traditional food produced from soybeans through a mould fermentation involving Rhizopus oligosporus. It is rich in bioactive phytochemicals, including isoflavones that are

Nutritive Value Between Fermented and Germinated Soybean: Γ-aminobutyric Acid, Amino Acids Content and Antioxidant Properties

In this study, soybean was subjected to both fermentation and germination process that was exposed either in an aerobic or anaerobic condition or combination of both. The γ-aminobutyric acid (GABA),

Nutritional values of tempe inoculated with different strains of Rhizopus: its γ-aminobutyric acid content and antioxidant property

The γ-aminobutyric acid (GABA) content and antioxidant profile of fermented soybean inoculated with eight different strains of Rhizopus sp. were studied. The ability of these strains, which were

Hepatoprotective Effect of Fermented Soybean (Nutrient Enriched Soybean Tempeh) against Alcohol-Induced Liver Damage in Mice

NESTE produced through fermentation process was able to enhance hepatoprotective and antioxidant effects in vivo, and histological examination on NESTE treatment group showed that this extract was capable of recovering the damaged hepatocytes to their normal structures.

Steaming Process Does Not Affect The Antioxidant Activities of Tempeh Ethanol Extract

Tempeh is an Indonesian fermented traditional food made from soybeans. It exhibits antioxidant activities mainly due to phytochemicals known as isoflavones. Since tempeh is mainly consumed cooked,

Tempeh Extract Protects HepG2 Cells Against Oxidative Stress-Induced Cell Death

It is shown that pretreament with tempeh extract protected HepG2 cells from oxidative stress triggered by TBHP (tert-butyl hydroperoxide) by reducing cellular ROS generation, TBARS levels, caspase-3 activity and eventually cell death.

Production and Evaluation of Soybean Tempeh to Use as a Ready to Eat Meal in Egyptian Hotels

Sensory evaluation of deep-frying and stewing fermented tempeh manufactured from soybean it could be concluded that the deep-fried soybean Tempeh was more susceptible than stewing soybeanTempeh.



The Production of a New Tempeh-like Fermented Soybean Containing a High Level of γ-Aminobutyric Acid by Anaerobic Incubation with Rhizopus

A cultivation procedure for the preparation of a new tempeh-like fermented soybean containing a high level of γ-aminobutyric acid was developed and showed that all of R. oligosporus and R. oryzae examined accumulated GABA in the anaerobically fermented soybeans showed the highest content of GABA.

Antioxidant activity of designed peptides based on the antioxidative peptide isolated from digests of a soybean protein

Antioxidative peptides showed synergistic effects with nonpeptidic antioxidants as observed in soybean protein and, among the peptides tested, Pro-His-His was the most antioxidative.

Antioxidative Activity of Peptides Prepared from Okara Protein

Protease hydrolyses of an Okara protein yielded antioxidative activity against the peroxidation of linoleic acid in an aqueous system at pH 7.0, which is nearly equal to that of carnosine.


Whole dried soybean seeds were investigated to determine the nature of their antioxidant activity. Activity was measured by rates of carotene bleaching in the coupled oxidation of linoleic acid and


Soybeans, defatted soy flour, soy protein concentrates, and soy isolates possess appreciable antioxidant activity in lipid-aqueous systems. The antioxidant properties of soybeans, defatted soy flour,

Antioxidative properties of tripeptide libraries prepared by the combinatorial chemistry.

The present results allow us to understand why protein digests have such a variety of antioxidative properties, including strong radical scavenging activities, but very weak peroxynitrite scavenging activity.

Antioxidant activity of polar carotenoids including astaxanthin-β-glucoside from marine bacterium on PC liposomes

SUMMARY: This study was aimed at evaluating the antioxidant activity of polar carotenoids (zeaxanthin, astaxanthin, and astaxanthin-β-glucoside) in free radical-mediated oxidation of

Antioxidant properties of ferulic acid and its related compounds.

The results indicated that not only the radical scavenging activity of antioxidants, but also their affinity with lipid substrates, might be important factors in their activity.

Determination of antioxidant activity of herbs by ESR.

Water extracts of 32 herbs that are constituents of curry and curry powder were screened for superoxide anion radical (O2.) scavenging activity, and only clove, allspice, and basil were shown to decrease DMPO-O2.- adduct yields.

Occurrence of Anserine as an Antioxidative Dipeptide in a Red Alga, Porphyra yezoensis.

The occurrence of carnosine and anserine suggests that the histidine-related compounds also contribute to the antioxidative reactions in P. yezoensis.
