Abstract:
Exploring the effects of high hydrostatic pressure (HHP) in biotechnology has received increased interest during the last decade. HHP has successfully been applied in the processes of pasteurization in the food and pharmaceutical industries. The application of HHP processing of food to extraction of active ingredients from natural biomaterial is a novel technique at present. The application of HHP processing of food to extracting lycopene from tomato paste waste was studied. Various experimental conditions of HHP processing process, such as solvents (chloroform, 95% ethanol and distilled water), ethanol concentration (45–95%, v/v), pressure (100–600MPa), duration (1–10 min) and solid/liquid ratio (1:1 to 1:8 g/ml), were investigated to optimize the extraction process. The experimental results of HHP showed that more lycopene can be extracted from tomato paste waste in only 1 min at room temperature without any heating process. The highest recovery (92%) was obtained by performing the extractions at 500MPa pressure, 1 min duration, 75% ethanol concentration, and 1:6 (g/ml) solid/liquid ratio. From the viewpoints of extraction time, the extraction yield and the extraction efficiency, extraction by HHP shows a bright prospect for extracting lycopene from tomato paste waste.
