 Whipped cream is one of the most popular dairy products with a complex structure of foam emulsion. Production of low fat whipped cream with fat substitutes is recommended with regard to the high fat content in whipped cream and side effects of fat on the public health. Based on, the effects of whey protein concentrate, carboxymethyl cellulose, xanthan gum and mix of them were investigated on the properties of low fat whipped cream. For this purpose, different amounts of them were determined by the surface response design and then they were added to the cream with 20% fat. Then, apparent viscosity, cream firmness, particle size distribution, foam stability, overrun tests, sensory evaluation, color characteristics (L *, a *, b *) were done on the samples. The results showed that fat substitutes in low fat whipped cream compared to the control sample were increased the apparent viscosity, overrun, firmness, foam stability and change in particle size (p<0/05). However, the stabilizers had no alone statistically effects on the color factors. Also, whey protein concentrate in compared with other treatments had the highest overrun and lowest particle size, xanthan gum had the lowest water leakage and carbohydrates, especially xanthan, had the highest viscosity and firmness (p<0/05). Based on the sensory evaluation data, optimal sample that contain 0.35 whey protein concentrate and 0.15 xanthan and carboxymethyl cellulose had statistically more desirable than control and other treatments in texture and overall acceptance. At the end, we pointed out that these additives could be a good alternative to reduce the percentage of fat in whipped cream due to they improve the physical, rheological and sensory properties of whipped cream without significant effects on the most of external parameters such as color and sensory.
