Cocoa Powder Effective In Treating Obesity-Related Inflammation In Mouse Model
A few cups of hot cocoa may not only fight off the chill of a winter's day, but they could also help obese people better control inflammation-related diseases, such as diabetes, according to Penn State researchers. Mice that were fed cocoa with a high-fat diet experienced less obesity-related inflammation than mice fed the same high-fat diet without the supplement, said Joshua Lambert, associate professor of food science. The mice ate the human equivalent of 10 tablespoons of cocoa powder -- about four or five cups of hot cocoa -- during a 10-week period... (Source: Health News from Medical News Today)

Effects of Locust Bean Gum and Mono‐ and Diglyceride Concentrations on Particle Size and Melting Rates of Ice Cream
This study also found an increase in the particle size values when MDG levels were held constant and LBG amounts were increased in the ice cream. Ice creams with higher concentrations of MDG and LBG together had the greatest difference in the rate of melting than the control. The melting rate decreased with increasing LBG concentrations at constant MDG levels. These results illustrated that fat aggregation may not only be affected by emulsifiers, but that stabilizers may play a role in contributing to the destabilization of fat globules. Practical Application  Fat aggregation is influential in providing structure and bo...

Effects of some oil-born yeasts on the sensory characteristics of Italian virgin olive oil during its storage.
Abstract The olive oil microbiota, mainly composed of yeasts, is associated with the suspended fraction of freshly produced olive oils. Some olive oil yeasts are considered useful as they are able to hydrolyse the bitter tasting secoiridoid compound of the oil, whereas others are considered harmful as they can damage the quality of the oil. Present research demonstrated the influence of some yeast strains belonging to Candida adriatica, Candida diddensiae and Candida wickerhamii species on the olive oil sensory characteristics during its storage. All the tested yeasts survived in the inoculated extra virgin olive o...

Tropomyosin Contains IgE‐Binding Epitopes Sensitive to Periodate but Not to Enzymatic Deglycosylation
Abstract  Glycosylation has been reported to affect the epitopes of food allergens, however, there are few reports on its role in crab allergen. In the present study, the effect of glycosylation on the IgE‐binding activity of tropomyosin (TM), a major allergen in Scylla paramamosain, was investigated. The results showed that TM was a glycoprotein with a 0.2% carbohydrate moiety and contained O‐glycan. Moreover, enzymatic deglycosylation of TM by glycosidase had no effect on the IgE‐binding activity of TM. In contrast, treatment with periodate resulted in a significant reduction in its IgE‐binding activity. (Sourc...

Effect of the Addition of Basil Essential Oil on the Degradation of Palm Olein during Repeated Deep Frying of French Fries
Abstract  The potential antioxidant power of basil essential oil under frying conditions was explored. Two concentrations (200 or 500 ppm) were added to palm olein (PO) to evaluate their effect on fat oxidation/degradation during repeated frying of French fries at 180 °C. A higher oxidative stability index was detected for PO with basil essential oil at 200 ppm. Both concentrations showed lower p‐anisidine values than PO without basil essential oil after 5 d of frying. Addition at 500 ppm resulted in the lowest total polar compounds and free fatty acids contents. Thus, the addition of basil essential oil improved the ...
