Abstract
There is a growing demand for nutritious food products that contain specific ingredients, such as long-chain polyunsaturated fatty acids (LCPUFAs). In the case of LCPUFAs, protection against lipid peroxidation is difficult, and microencapsulation emerges as an alternative. The aim of this research work is to develop mayonnaise containing spray-dried microcapsules (SDM). Fortified mayonnaise was developed using various treatments such as (T1) incorporating chia seed oil (CSO), (T2) incorporating fish oil (FO), (T3) incorporating blend of chia and fish oil, (T4) incorporating the SDM of CSO, (T5) incorporating the SDM of FO, and (T6) incorporating the SDM of chia and fish oil blend as well as controls. Thereafter, during the 15-day storage period, the fatty acids (FAs) composition, free fatty acids (FFAs), peroxide value (PV), and sensory properties of fortified mayonnaise were examined every 5 days. The overall results showed that the oxidative stability of mayonnaise formulated with SDM has been improved, and it can be used as a fortifying agent in the processing of many food products. Treatments containing SDM of up to 4% did not differ from the control in sensory analysis. Sensory scores of SDM samples showed a slight decrease in off-flavor scores and were in an acceptable range. Therefore, SDM developed from CSO and FO blends can be recommended for supplementation in different food products for long-time storage.
