Red pitaya fruit has become a source of natural colorant, because it is rich in betalains, a pigment that imparts a red‐purple color that interests the food and cosmetics industries. This fruit also possesses high nutritional value, with a range of bioactive compounds known to confer potential health benefits and prevent chronic diseases, such as diabetes, which makes it useful for use as pharmaceutical agents and dietary supplements. In order to improve its technological and biological effects, a concentration will be required. Thus, the microfiltration, followed by vacuum concentration, can be an interesting strategy for this purpose. This study aimed to explore tangential microfiltration to produce microfiltered material, which is an important step to obtain the microfiltered red‐purple pitaya concentrate. Therefore, physicochemical and chemical characterization (including 1H NMR analysis) and biological properties (toxicity and diabetes) of this concentrate were assessed, using adult zebrafish as a model. The results show that microfiltration was carried out efficiently, with an average consumption of 95.75 ± 3.13 and 74.12 ± 3.58 kW h m−3, varying according to the material used ("unpeeled pitaya pulp" or "pitaya pulp with peel," respectively). The in vivo tests indicated non‐toxicity and hypoglycemic effect of the concentrate, since the blood glucose levels were significantly lower in the zebrafish groups treated with this concentrate in comparison with that of control group. Thus, this study suggests the potential of microfiltered red‐purple pitaya concentrate as a promising multifunctional food‐derived colorant, exhibiting beneficial biological effects far beyond its attractive color. Practical Application: Hylocereus polyrhizus (F.A.C. Weber) Britton & Rose has attracted attention as a potential source of natural colorants because of its red‐purple skin and flesh color. In addition, this fruit has a range of bioactive compounds, which make it a valuable resource for providing potential health benefits and preventing chronic diseases such as diabetes. In this paper, the microfiltered red‐purple pitaya concentrate showed beneficial biological effects far beyond its attractive color. Thus, this product can be considered a promising multifunctional food‐derived colorant to use in the food, pharmaceutical, or cosmetics industries. [ABSTRACT FROM AUTHOR] |
