Impact of foaming conditions on quality for foam-mat drying of Butterfly pea flower by multiple regression analysis

Abstract

In recent years, the Butterfly pea flower has been increasingly interested in its color and function. However, the preservation of the extract faced many difficulties; therefore, foam drying technology was applied to solve this problem. The study was conducted to determine the effect of foaming conditions, including albumin ratio, carboxymethyl cellulose (CMC) ratio, and whipping time on foam characteristics. At the same time, the multi-dimensional regression method was also used to determine the most suitable foaming conditions for the following process. The research results showed that all 3 factors strongly influenced the foaming process of pea flower extract. It could be concluded that the most suitable condition for foaming is to use 9.3% albumin, 0.79% CMC and stir for 19 min. Under these conditions, the foam expansion and stability were 584.79% and 96.44% respectively. The powder obtained from the foam drying of Butterfly pea flower extract was also analyzed for quality. The temperature of 65 oC for 4 hrs gave relatively high-quality powder with protein content, anthocyanin and antioxidant activity of 9.89 g/100g, 1.15 mg/g and 87.34% respectively. In conclusion, the foam-mat dried powder from butterfly pea flower extract is suitable for other processing processes, especially in the processing of folk cakes, pasta and bread industry.

“…In contrast, when subjected to temperatures of 70 o C and 80 o C, the duration of the drying process is expedited, resulting in a notable decrease in the overall phenolic content. The potential reason for this phenomenon could be attributed to the inherent susceptibility of the bioactive chemical to undergo alterations, oxidation, and decomposition when exposed to prolonged high temperatures (Thuy et al, 2022b;Thuy et al, 2023). The findings obtained exhibit a notable resemblance to the research conducted by Thuy et al (2023), wherein the optimal drying temperature for the foamdrying process of butterfly pea flower extract was investigated.…”

The same trend with the change in total phenolic compound was observed in the effect of drying temperature on anthocyanin content and antioxidant activities.…”

“…Foaming expansion and stability are two of the most important factors for the foam-mat drying process. The high expansion and good stability could maintain the quality as well as reduce the drying time (Dehghannya et al, 2018;Thuy et al, 2023). Egg albumin in this study contributed to the foaming production, and xanthan gum was considered to have foaming stability (Martínez-Padilla et al, 2015).…”

“…In addition, egg albumin, carboxymethyl cellulose, and digestion-resistant maltodextrin were used for foaming the extract from mullbery (Thuy et al, 2022d), which also showed good foaming conditions. However, most studies used egg album and xanthan gum as foaming agents due to high foaming properties as foaming stability and foaming expansion (Thuy et al, 2022c;Thuy et al, 2023;Thuy et al, 2022e). These products maintained a high content of antioxidants as well as high acceptability from a consumer perspective.…”
