摘 要:本實(shí)驗(yàn)主要用微波萃取法提取三角梅中的紅色素。在不同的乙醇濃度,微波功率,提取時(shí)間以及料液比等條件下對(duì)三角梅進(jìn)行微波法提取。采用單因素與正交試驗(yàn)設(shè)計(jì),確定出微波提取的最佳工藝條件為:乙醇濃度65%、提取功率為460W、微波時(shí)間為60S、料液比為1:10,其中濃度和料液比是主要的影響因素.之后再對(duì)提取出的色素在不同溫度,PH等條件下的穩(wěn)定性進(jìn)行研究。得出三角紅色素在光照條件下較為穩(wěn)定,在較高濃度NaCl溶液中穩(wěn)定性較差,適用于酸性條件的結(jié)論。本實(shí)驗(yàn)為三角梅進(jìn)行深加工提供經(jīng)濟(jì)可行的工藝參數(shù),使之更好的投入實(shí)際生產(chǎn),充分體現(xiàn)三角梅紅色素的經(jīng)濟(jì)價(jià)值及工業(yè)應(yīng)用價(jià)值,且為三角梅工業(yè)化生產(chǎn)提供可靠依據(jù)。 關(guān)鍵詞:三角梅;色素;微波提取;穩(wěn)定性
ABSTRACT:The experimental research SanJiaoMei with the red pigment extracted microwave method. Fresh SanJiaoMei cut into pulverized. In different ethanol concentration, microwave power, extraction time and under the condition of liquid materials such as SanJiaoMei than for microwave method of extraction. Through the single factor experiment results design orthogonal experiment SanJiaoMei SanJiaoMei red pigment extracted from the optimum technological conditions. Then to the extracted pigment in different temperature, PH value stability under such conditions. This study for processing SanJiaoMei provide financially feasible process parameters, make better into actual production, fully embodies the economic value and SanJiaoMei red pigment industrial application value, and to provide theoretical basis SanJiaoMei research development. Keywords: SanJiaoMei; Microwave method; pigment; stability |
