Potential of lactic acid bacteria in aflatoxin risk mitigation.

Aflatoxins (AF) are ubiquitous mycotoxins contaminating food and feed. Consumption of contaminated food and feed can cause a severe health risk to humans and animals. A novel biological method could reduce the health risks of aflatoxins through inhibiting mold growth and binding aflatoxins.

ACE-inhibitory and antioxidant properties of potato (Solanum tuberosum).

Proteins were isolated from potato tubers (Solanum tuberosum) at different physiological states, and by-products from the potato industry were used to evaluate their ACE-inhibitory and radical-scavenging potencies. Protein isolates and by-products were autolysed or hydrolysed by alcalase, neutrase and esperase. Hydrolysis increased the inhibition of the angiotensin-converting enzyme (ACE) and the radical-scavenging activity.

Effect of processing and storage on the stability of flaxseed lignan added to dairy products.

This study investigated the effects of processing and storage on the stability of purified, flaxseed-derived secoisolariciresinol diglucoside (SDG) added to milk prior to the manufacture of different dairy products. We analyzed the effect of high-temperature pasteurization, fermentation, and milk renneting as well as storage on the stability of SDG added to milk, yogurt, and cheese. Also, the stability of SDG in whey-based drinks was studied.

Effect of processing and storage on the stability of flaxseed lignan added to bakery products.

The study focused on the effects of processing and storage on the stability of flaxseed-derived secoisolariciresinol diglucoside (SDG) added to various bakery products. The SDG concentration of doughs, baked rye breads, graham buns, and muffins was analyzed by high-performance liquid chromatography-diode array detection; the baked products were analyzed immediately after baking and upon storage at room temperature for 1 week and at -25 degrees C for 1 and 2 months, respectively. Added SDG was found to withstand normal baking temperatures in all bakery products.
