Abstract

Red beet pigments, betacyanin and betaxanthin, possess both health benefits and potential as natural colorants. This study investigated the efficacy of Microwave-Assisted Extraction (MAE) for their extraction from red beets. Pretreated beets were subjected to MAE employing varying microwave power levels (200, 400, and 600 W) and solvents (water, ethanol, and ethanol + citric acid). Betacyanin content varied from 23.77 to 59.28 mg/100g. Higher microwave power significantly increased betacyanin yield (p < 0.05), while the type of solvent did not exert a significant influence. Betaxanthin content was also affected by both microwave power and solvent polarity. Higher power settings and the more polar solvent mixture (ethanol + citric acid) resulted in greater extraction. These findings demonstrate the effectiveness of MAE for extracting both pigments from red beets, with optimal conditions dependent on the target compound of interest.

Abstract

Cooking oil is high enough economic value. Cooking oil is generally used to cook, but its uses are also many other than for cooking needs, such as skin beauty, lubricants and others. In the condition which the longer time, the price of cooking oil is higher than before, making some society to think creative by recycling the oil which has been used cooking oil. According to the research, it is know that sugarcane waste have strong adsorption potency to water content, and free fatty acid content that found in used cooking oil. The variable of this research are the rinsing time and the amount of sugarcane waste used. The best condition reaches to 40 gr sugarcane waste with the decrease water content reach 0.0050%; the rinse of sugarcane waste in 2x24 hours with free fatty acid intensity adsorption up to 0.23%
