The antioxidant activity of nano‐enca...

Bitter Gourd fruit is a rich source of antioxidants and anti-diabetic compounds but due to its instability and bitter taste, there are limitations for adding in food formulations. Our goal was to load this charantin-rich extract within nanoliposomes; the studied variables were different concentrations of lecithin (1, 3, 5% w/w) and extract (0.5, 1%...

The effect of ripening time on the microstructural, physicochemical and rheological characteristics of traditional Kope cheese ripened in clay pots was investigated. The moisture content, pH and total nitrogen (TN)/dry matter (DM) of the cheese decreased, and DM, fat in DM and water-soluble nitrogen/TN increased during this period. Storage and loss...

Aspergillus sp. is known to produce cholesterol reducing drug-lovastatin. Lovastatin is a naturally occurring drug found in food such as red yeast rice (red rice koji or red fermented rice, red koji rice, red koji rice, anka, or ang-kak). Lovastatin (mevinolin) was the first hypocholesterolemic drug to be approved in 1987 by Food and Drug administr...

In this research, physicochemical properties and oxidative stability of Roghani virgin olive oil grown in two regions of Roodbar and Kazeroon, located in north and south of Iran respectively, with differences in pedoclimatic conditions, altitude and soil were investigated. To determine the physicochemical properties, acidity, peroxide value, spectr...

Recently, Subcritical Water Extraction (SWE) has been well known as a green technology for extraction of bioactive compounds from plants. In this study, Subcritical water extraction, ultrasound assisted extraction (UAE) and shaker solvent extraction (SSE) were compared for extraction of phenolic compounds from fig (Ficuscarica) pulp and skin. Antio...

In the present study 42 pcs fresh Rainbow Trout were prepared and divided into two groups.
