Study on Extraction of Nutrients from Coffee Production Wastewater

The wastewater from coffee production is rich in nutrients, especially pectin and protein, but there are few studies on the effective extraction and utilization of these resources. The purpose of this experiment is to explore the extraction methods of pectin and protein from coffee wastewater, including acid extraction, enzyme extraction and ultrasonic extraction, and to determine the content of protein and total sugar by photometer. Through experiments, we can effectively extract these valuable nutrients and provide reference for the resource utilization of coffee production wastewater.
