Influence of fat replacers on chemical composition, proteolysis, texture profiles, meltability and sensory properties of low-fat Kashar cheese

Changes in chemical composition, proteolysis, lipolysis, texture, melting and sensory properties of low-fat Kashar cheese made with three different fat replacers (Simplesse D-100, Avicel Plus CM 2159 or beta-glucan) were investigated throughout ripening. The low-fat cheeses made with fat replacers were compared with full- and low-fat counterparts as controls. Reduction of fat caused increases in moisture and protein contents and decreases in moisture-in-non fat substance and yield values in low-fat cheeses. The use of fat replacers in the manufacture of low-fat Kashar cheese increased water binding capacity and improved overall quality of the cheeses. Use of fat replacer in low-fat cheese making has enhanced cheese proteolysis. All samples underwent lipolysis during ripening and low-fat cheeses with fat replacers had higher level of total free fatty acid than full- or low-fat control cheeses. Texture attributes and meltability significantly increased with addition of fat replacers. Sensory scores showed that the full-fat cheese was awarded best in all stages of ripening and low-fat variant of Kashar cheeses have inferior quality. However, fat replacers except beta-glucan improved the appearance, texture and flavour attributes of low-fat cheeses. When the fat replacers are compared, the low-fat cheese with Avicel Plus CM 2159 was highly acceptable and had sensory attributes closest to full-fat Kashar cheese.

Characteristics of low-fat whipped cream containing protein-based fat replacers

Fat replacers are used to alleviate functional and sensory deficits in whipped cream caused by fat reduction. Of all known fat replacers, proteins have shown the most effective ability to replace fat due to their nutritional attributes and functional properties. Recently, several protein-based fat replacers were investigated, but among all of them, the use of milk proteins and modified proteins, especially their complex with polysaccharides presented promising results. Therefore, due to the growing interest in this field, this review focussed on the mechanism for fat replacement with proteins and their complexes, and the characteristics of low-fat whipped cream affected by these proteins, and finally considered the challenges and perspectives in the future.     

Flavor Interactions with Fat Replacers: Effect of Oil Level

The influence of fat and various fat replacers on headspace concentration of flavor compounds was studied. Fat had a predictable influence on vapor pressure of flavor compounds relating to their fat solubility. Protein-based fat replacers behaved more like fat than did carbohydrate-based products which had little interaction. Protein-based products had substantial effects on saturated and unsaturated aldehydes.
