The aim of this study was to assess the effects pectin coating alone (PE) or combined with chemical dips containing potassium sorbate (PS) sodium benzoate (SB) as antimicrobials, and N-acetyl cysteine (N-AC) ascorbic acid (AA) + citric (CA) antibrowning agents, on weight loss, color values, browning index, firmness, titratable acidity, soluble solids content, total phenolic antioxidant activity...

Geotrichum candidum causal agent of tomato sour rot, has the potential to infect a wide variety fruits and vegetables. In this work, in vitro antifungal activity Chitosan (Chi), Potassium Sorbate (PS), Sodium Bicarbonate (SB), Carbonate (SC) their mixtures were evaluated. The PS SC treatments showed 100% inhibition mycelial growth (MG), germination, sporulation. Regarding SB, 1.5 2.0% concentra...

Cornelian cherry (Cornus mas L.) fruits are known for their significant amounts of anthocyanins which can be used as natural food colorants. The storage stability of anthocyanins from these fruit extracts, at different temperatures (2 °C, 25 °C and 75 °C), pH 3.02, in the presence of two of the most widely employed food preserving agents (sodium benzoate and potassium sorbate) was investigated....

Globe artichoke (Cynara scolymus L.) is a perennial rosette plant grown throughout the world for its large, fleshy heads [1-3]. Most of its culture (about 90%) is concentrated in the countries around the Mediterranean Basin mainly in Italy (50 000 ha), Spain (17000 ha) and France (10 000 ha) [4]. Egypt has the potential to develop an excellent export industry in artichoke. The production areas ...

Weak organic acid food preservatives exert pronounced culture pH-dependent effects on both the heat-shock response and the thermotolerance of Saccharomyces cerevisiae. In low-pH cultures, they inhibit this stress response and cause strong induction of respiratory-deficient petites amongst the survivors of lethal heat treatment. In higher pH cultures, 25 degrees C sorbic acid treatment causes a ...

Sorption reactions, involving both inorganic and organic particulates, are an important control on the transport and fate of many trace elements in natural systems. Understanding the controls on trace-element concentrations in waters is critical for a number of applications including the transport of contaminants and nutrients, geochemical prospecting, agriculture, municipal and industrial wate...

Food additives have contributed to safe and stable supply of food. Although acceptable daily intake (ADI) has been used for the safety assessment of each food additive, their synergistic and/or combined effects on our health are unclear. Actually, several food additives are usually used together in a food, therefore, they may have some adverse effect on cellular levels and/or whole animals even...
