Abstract

Clitoria ternatea L. commonly known as butterfly pea contain a great variety of bioactive compounds and its flower petals containing anthocyanins thus it has a potential to be a natural food colorant. Butterfly pea flower is still rarely used in food products because the anthocyanins and the other bioactive compounds are unstable and sensitive to pH, temperature, or light. The aim of this research is to retain the anthocyanin compounds of butterfly pea flower extract using microencapsulation. This research is divided into two stages. In the preliminary stage, butterfly pea flower were extracted using ethanol. In the main stage, the butterfly pea flower extract was encapsulated by using different coating material ratio (maltodextrin and Whey Protein Isolate (WPI) with ratio 1:0, 1:1, 0:1) and spray dryer inlet temperature (130, 150, 170°C). The microcapsules were analyzed for its moisture content, powder recovery, anthocyanins content, encapsulation efficiency, phenolics content, solubility, particle size, and color measurement. The result showed that the yield of butterfly pea extract was 17.09%, moisture content 22.58%, anthocyanins content 939.31 mg/L, phenolics content 44.28 mg GAE/g sample, and antioxidant activity IC₅₀ 853.74 ppm. From this research, it was found that coating material ratio and spray dryer inlet temperature affect on the characteristics of butterfly pea extract microcapsule. Butterfly pea extract microcapsules which encapsulated using WPI at 150°C gave the greatest result with moisture content 4.65%, powder recovery 50.75%, anthocyanins content 50.10 mg/L, encapsulation efficiency 97.30%, phenolics content 10.65 mg GAE/g sample, solubility 83.67%, particle size 1.22 µm, lightness L* 63.40, hue 211.25°, and antioxidant activity IC₅₀ 10058.21 ppm.
