Reduced Fat Food Emulsions: Physicochemical,Sensory, and Biological Aspects

Fat plays multiple important roles in imparting desirable sensory attributes to emulsion-based food products, such as sauces, dressings, soups, beverages, and desserts. However, there is concern that over consumption of fats leads to increased incidences of chronic diseases, such as obesity, coronary heart disease, and diabetes. Consequently, there is a need to develop reduced fat products with desirable sensory profiles that match those of their full-fat counterparts. The successful design of high quality reduced-fat products requires an understanding of the many roles that fat plays in determining the sensory attributes of food emulsions, and of appropriate strategies to replace some or all of these attributes. This paper reviews our current understanding of the influence of fat on the physicochemical and physiological attributes of food emulsions, and highlights some of the main approaches that can be used to create high quality emulsion-based food products with reduced fat contents.

Efficacy of the Antimicrobial Peptide Nisin in Emulsifying Oil in Water

Nisin is an amphiphilic, antimicrobial peptide that has found application as a preservative in the food industry. Evaluation of nisin as an emulsifier was accomplished by measuring its ability to stabilize dispersed oil droplets in water. This was achieved by monitoring the time-dependent electrical conductivity of the dispersion. Nisin solutions at concentrations of 0.1, 0.5, 1, 5, and 10 mg/ml were used to prepare emulsions, by homogenization of a volume of nisin solution and corn oil. While nisin showed significant emulsifying capacity in comparison to Tween® 80 and β-casein, its emulsifying properties were found to be highly concentration- and pH-dependent.

Lactic Acid Fermentation of Edible Mushrooms: Tradition,Technology, Current State of Research: A Review

Pickling is one of the methods for preserving food. However, this term may refer to both types of products, that is, to those subjected to lactic acid fermentation and to marinated ones (acidified) that are usually produced by the addition of acetic acid. Various raw materials are subjected to lactic acid fermentation (vegetable and animal origin), which yields food products with high nutritional and dietary value. In many regions of the world, the process of lactic fermentation is also traditionally used to preserve fruiting bodies of edible mushrooms. Mushrooms are appreciated for their organoleptic qualities as well as the presence of many different bioactive substances exhibiting healing and health‐promoting properties. This article reviews the literature related to the use of lactic fermentation in the process of mushroom preservation. Particular attention has been paid to the aspects of the technological process and its impact on the quality and suitability of the final products. Moreover, research results concerning the influence of lactic fermentation on chemical and physical changes in fruiting bodies of edible fungi are also presented.
