Abstract:
Cauliflower foliage was used as the raw material for extracting chlorophyll with microwave extraction. Some factors were considered for single factor experiment，such as size of cauliflower foliage powder, density of cell wall crack agent, microwave power, irradiation time, extractant concentration,solid-liquid ratio. L16(45) orthogonal experiment was adopted for getting the optimal mixed test conditions. The result showed that the extraction ratio of chlorophyll could be achieved as 6.843mg/g under the following conditions：60% of density of cell wall crack agent, 30s of irradiation time, 90% of extractant concentration and 1:20 of solid-liquid ratio. Compared with the traditional technology, microwave assisted extraction method can increase extracting rate of chlorophyll by 62.2%.
