Resumo

Capsicum oleoresin has potential health benefits, particularly against obesity markers. Due to its high pungency, few studies have been done to explore the intake of this ingredient. The objective of this study was to use the Capsicum oleoresin (CO) microencapsulated into a high-fat diet to evaluate its metabolic effect on mice. Two formulation containing 15 % solids were prepared: the first (F1) with 5% CO and 95% emulsifier, and the second (F2) with 2.5% corn oil, 2.5% CO, and 95% emulsifier. These formulation were atomized in a spray dryer. Ultra-Performance Liquid Chromatography determined the capsaicin content for both formulations. Mice were divided into two groups: lean control (normocaloric AIN diet, n = 10) and high fat (HF diet: hypercaloric, n = 30), which were subdivided into three subgroups: HF control diet (n = 10); diet F1: HF + 20 % CO oleoresin microparticles (n = 10); and diet F2: HF + 20 % CO microparticles containing corn oil (n = 10). The animals treated with the microparticles showed lower glucose levels than the HF control. Mice fed with HF-containing CO microparticles had cholesterol blood levels similar to that of the lean group and lower (<100 mg/dL) than that of the HF control group (150 mg/dL). Capsicum oleoresin microparticles added to high-fat diets promoted lower weight gain and protected the liver against hepatic steatosis. Leptin levels for mice fed with HF diet plus CO microparticles averaged between 2 and 5 ng/ml, whereas the fat control group developed leptin resistance. Capsicum microparticles evidenced a protective effect against dyslipidemia compared to the fat control group, which suggests their use as a potential ingredient for the control of obesity. (AU)
