Effects of Green Extraction Methods on Antioxidant and Antimicrobial Properties of Artichoke ( L.) Leaves.

Research Background: Artichoke leaves, an important waste product of the food industry, have an important antioxidant and antimicrobial capacity. Although there are several studies in the literature to determine their antioxidant and antimicrobial activity, a comparison of green extraction technologies including microwave, ultrasound probe and ultrasound bath methods in relation to the maceration technique has not been performed. Also, several parameters such as the extraction temperature, power, extraction mode and extraction time are important parameters for obtaining targeted compounds in the highest amount.

Melon seed: A nutritionally valuable by-product and its effects on cake quality.

Incorporating by-products and waste materials with nutritional and industrial potential into food formulations is an important consideration. Melon seeds, known for their nutritious compounds, are often treated as waste. This study aimed to improve the nutritional properties of cakes by adding melon seed flour (MSF), which contains high levels of ash, lipid, protein, and fiber, as a substitute for whole wheat flour and fat at concentrations of 40% and 60%.

Cold-set or hot-set emulsion gels consisted of a healthy oil blend to replace beef fat in heat-treated fermented sausages.

The current work aimed to investigate the utilization of gelled emulsion (GE) systems stabilized either with cold or hot gelation consisted of peanut and linseed oils as fat replacers in fermented beef sausages. The reformulation provided a healthier lipid profile, that led to decreasing total lipid content, cholesterol, and SFAs (from 46.6% to 23.

Peanut and linseed oil emulsion gels as potential fat replacer in emulsified sausages.

The study aimed to highlight the utilization of gelled emulsion (GE) systems containing peanut and linseed oils to replace beef fat partially or completely in emulsified sausages. Total fat content was reduced by up to 40% and energy content was lowered by up to 27% in reformulated products. Saturated fatty acids and cholesterol were successfully decreased while noticeable increments were provided in mono and poly-unsaturated fatty acids in sausages containing GE.

Health importance of arsenic in drinking water and food.

Arsenic is a toxic metalloid of global concern. It usually originates geogenically but can be intensified by human activities such as applications of pesticides and wood preservatives, mining and smelting operations, and coal combustion. Arsenic-contaminated food is a widespread problem worldwide.

Probiotics and health.

Probiotics are described as live microbial food ingredients that are beneficial to health of the of host, especially by improving intestinal microbial balance. The major consumption of probiotics is in dairy-based foods form, which is containing intestinal species of Lactobacillus and Bifidobacterium. A number of potential benefits of probiotics have been proposed, including: adherence to cells; exclusion or reduction of pathogenic adherence; production of acids, hydrogen peroxide, and bacteriocins antagonistic to pathogen growth; safe, noninvasive, noncarcinogenic and nonpathogenic characteristics; and congregation to form a normal balanced flora.
