Oxidative stability of sunflower and soybean oils enriched with black plum peel extract in comparison with synthetic antioxidants.

Black plum peel is the by-product of plum processing and is a valuable source of antioxidants and phenolic compounds. In this research, total phenolic compounds, total flavonoid content and antioxidant activity of black plum peel were measured. After that, black plum peel extract (in concentrations 0, 400, 800, 1200 and 2000 ppm) as a natural antioxidant for improving the stability of soybean and sunflower oil was used.

The effect of different spices on the moisture content, texture characterizations and consumer preferences of roasted sunflower seeds.

Roasting is an important process in the industry of nuts and seeds production. The aim of this study was the effect of different spices (red pepper, paprika, hibiscus tea, curry powder, sistani wrench, black plum peel puree, caraway, fennel, vegetables) on the moisture content, texture characterizations and sensory properties of roasted sunflower seed. The roasting process was performed under similar industrial conditions.

Investigating the effect of sensory properties of black plum peel marmalade on consumers acceptance by Discriminant Analysis.

One of the goals of producing and developing new products is to provide desirable features to the target community, followed by promoting marketability and gaining more market share in similar products basket. In this study, in order to investigate the effect of sensory characteristics of black plum marmalade on its acceptance, sample data with 180 observations and discriminant analysis method were used. The sensory properties that were evaluated in this product included color, flavor, firmness, adhesiveness and spreadability.

Sensory and instrumental texture assessment of roasted pistachio nut/kernel by partial least square (PLS) regression analysis: effect of roasting conditions.

Roasting is an important step in the processing of pistachio nuts. The effect of hot air roasting temperature (90, 120 and 150 °C), time (20, 35 and 50 min) and air velocity (0.5, 1.

Effect of frying temperature and time on image characterizations of pellet snacks.

The development of non-destructive methods for the evaluation of food properties has important advantages for the food processing industries. So, the aim of this study was to evaluate the effects of frying temperature (150, 170, and 190 °C) and time (0.5, 1.

Effect of deep-fat frying on sensory and textural attributes of pellet snacks.

In this paper, the effects of several frying parameters on the quality of indirect expanded snacks were studied. Pellets, in two colors of yellow and green, were deep-fat fried at 150, 170, and 190 °C for 0.5, 1.
