    The effect of replacing egg yolk with sesameā€“peanut defatted meal milk on the physicochemical, colorimetry, and rheological properties of lowā€cholesterol mayonnaise

    Egg yolk was replaced with sesameā€“peanut meal milk in mayonnaise in the levels of 0, 25%, 50%, 75%, and 100%. The pH was significantly decreased by increasing the percentage of replacement in all three kinds of replacement (p < .05). However, over the whole period, no significant difference was observed in the acidity. The mayonnaise samples, except for the replacements of 50%, were desirable in terms of physical and thermal stability. A significant decrease was seen in lightness (L*) and yellowness (b*) of the samples as a result of an increase in the percentage of replacements (p < .05). In the power law model, the flowing index amount (n) of all samples was in the domain between zero and one, which served as evidence for pseudoplastic behavior (dilatant with shear) of mayonnaise samples. The positive results are employing suitably the sesameā€“peanut meal milk instead of egg yolk, decreasing the cholesterol of mayonnaise and increasing its nutritional value, proposing mayonnaise factories to make use of the meal of the oil extraction factory as emulsifier, which lead to a decrease in overall costs of producing these products

    In this study, the shelf life of fresh-cut iceberg lettuce (Lactuca sativa L.) was evaluated. Lettuce samples were washed with disinfectant agents and sodium hypochlorite and then soaked in an ascorbic acid solution. Next, samples were stored packaging films containing three levels (1% and 3% and 0% as a control film) of nano bentonite particles (NBPs) filler in a modified atmosphere for 12 days at 4 ā„ƒ. Various physicochemical parameters such as color, texture, pH, titratable acidity, dehydration, moisture, dry matter, chlorophyll content, microbial quality and sensory properties were investigated. Results indicated that nano-packaging had a significant ability to maintain the sensory, physicochemical properties of lettuce at the fifth (1% nano-composite film) and ninth (3% nano-composite film) days of storage compared to the control films. The greatest growth of molds and yeasts were observed in the control films which demonstrates the effectiveness of the application of bentonite nanoparticle fillers

    The aim of this study was to evaluate the presence and possibility of extracting compounds with antioxidant properties of soybean cake to extend the storage stability of soybean oil. Results showed that the highest DPPH radical scavenging activity was observed for sample to solvent ratio 1:25 while extracting by 70% ethanol for 3 h). The most phenolic compounds equivalents (Gallic acid) was observed for sample to solvent ratio 1:25 while extracting by 70% methanol for 14 h. In addition, the soybean cake extract at concentrations of 50, 100, 150 and 200 ppm in soybean oil could significantly lower the peroxide, diene and p-anisidine values of soy oil during storage at 65 A degrees C
