Traditional and Domestic Cooking Dramatically Reduce Estrogenic Isoflavones in Soy Foods.

Soybean is a pulse which has considerable nutritional value due to its high protein, fibers and polyunsaturated fatty acid (PUFA) contents. It also contains phytoestrogenic compounds that definitely hinder its recommendation for general consumption. Contrary to ancient times, when soybeans were boiled, modern commercial soy foods can contain up to 150 mg/100g of estrogenic isoflavones.

Safety assessment of Bacillus subtilis CU1 for use as a probiotic in humans.

Bacillus subtilis CU1 is a recently described probiotic strain with beneficial effects on immune health in elderly subjects. The following work describes a series of studies supporting the safety of the strain for use as an ingredient in food and supplement preparations. Using a combination of 16S rDNA and gyrB nucleotide analyses, the species was identified as a member of the Bacillus subtilis complex (B.

Removing isoflavones from modern soyfood: Why and how?

Estrogenic isoflavones were found, in the 1940s, to disrupt ewe reproduction and were identified in soy-consumers' urine in 1982. This led to controversy about their safety, often supported by current Asian diet measurements, but not by historical data. Traditional Asian recipes of soy were tested while assaying soy glycosilated isoflavones.

Structural investigation and homology modeling studies of native and truncated forms of alpha-amylases from Sclerotinia sclerotiorum.

The filamentous ascomycete Sclerotinia sclerotiorum is well known for its ability to produce a large variety of hydrolytic enzymes for the degradation of plant polysaccharide material. Two alpha-amylases designated as ScAmy54 and ScAmy43 were biochemically characterized and predicted to play an important role in starch degradation. Those enzymes produce specific oligosaccharides, essentially maltotriose, that have a considerable commercial interest.

The safety of two Bacillus probiotic strains for human use.

Probiotics based on Bacillus strains have been increasingly proposed for prophylactic and therapeutic use against several gastro-intestinal diseases. We studied safety for two Bacillus strains included in a popular East European probiotic. Bacillus subtilis strain that was sensitive to all antibiotics listed by the European Food Safety Authority.
