Extensive consumption of confectionery cream and production of products with reduced fat, strengthens the need to replace stabilizing and emulsifying compounds in it. Therefore, in this study, the effect of adding modified basil seed gum (BSG) and rice bran protein isolate (RBP) was investigated. First, the amount of insoluble aggregates and turbidity of basil seed gum solutions and rice bran protein at pH 3, 5 and 7 were investigated. Then, in confectionery creams with 25, 30 and 35% fat content in concentrations of 0.5 and 1% were added and the characteristics of volume increase, foam stability and firmness of confectionery cream were studied as important physicochemical characteristics of cream. The results showed that the highest amount of insoluble accumulations was obtained in basil seed gum at pHs 3 and 5 and the lowest in rice bran protein isolate at pH 7. In contrast, the highest turbidity was observed for RBP at pH 7 and the lowest turbidity in BSG at the same pH. The highest increase in volume and stability of confectionery cream foam was obtained in RBP in 30% fat cream, followed by RBP with 25% fat cream and whey protein containing 35% fat cream. In contrast, the lowest increase in volume was observed in BSG samples.I n contrast, confectionery cream with the highest percentage of fat and the highest amount of basil seed gum had the highest texture firmness. Therefore, according to the results, it is clear that pastry cream with the highest percentage of fat and the least amount of protein can lead to maximum foam stability. Overall, the results showed that RBP has a good ability to be used in confectionery cream formula, although BSG is not able to be used in cream due to lack of protein.
