Production of yogurt-like product from almond milk enriched with egg white protein powder and different dissaccharides

Abstract

Objective: The objective of this study was to produce a non-dairy yogurt-like fermented product by enriching almond milk obtained from almonds, whose functional properties are well known, with egg white protein powder (EWPP) and sucrose - maltose. Material and Methods: Sucrose and maltose were added to almond milk at a rate of 1.0% w/v. Afterwards, sucrose and maltose milks were pasteurized at 85 °C for 20 minutes and cooled. Following the cooling, the egg white protein powder (6% w/v) and the dry matter were adjusted to 12-13%. In this study, physico-chemical, rheological and sensory properties of yogurt-like products were determined on the 1st, 7th, 14th and 21st days of storage. Fatty acid compositions were determined on the first day of storage. Results: It has been determined that non-dairy fermented products produced from almond milk have similar properties to yogurt made from cow's milk in terms of physico-chemical, sensory, rheological and microbiological properties. However, it was also determined that yogurt-like products produced with the addition of maltose were more acceptable than the fermented products with the addition of sucrose in terms of all parameters. Conclusion: It has been concluded that it is possible to produce yogurt-like fermented milk products using different disaccharides from almond milk, and it can be an alternative to fermented milk products produced from animal milk.
