Experiment Study on Ultrahigh Pressure Extraction of Protein Components from Sika Deer Pilose Antler

Abstract

An Ultrahigh pressure extraction technique (UPET) is presented for the extraction of protein components from sika deer pilose antler. Various experimental conditions of the UPET process, such as extraction pressure (50-300 MPa), extraction time (0-10 min) and liquid/solid ratio (2-10 mL•g−1), were investigated to optimize the extraction process. The content of protein components in pilose antler extract by UPET for 4 min was higher than those using ultrasonic extraction (UE) for 30 min, heat reflux extraction (RE) for 12 h and soaking extraction (SE) at room temperature for 24 h respectively. From the viewpoints of extraction time, the proteins content in pilose antler extract and energy consumption in the extraction process, UPET was more effective than the conventional extraction methods studied.
