摘 要：植桑養(yǎng)蠶是我國一些地區(qū)的傳統(tǒng)產(chǎn)業(yè)，在養(yǎng)蠶過程年產(chǎn)近百萬噸的蠶沙。為了合理利用蠶沙資源，本課題主要研究了制備葉綠素銅鈉鹽的新工藝，并優(yōu)化了工藝條件，以指導(dǎo)工業(yè)生產(chǎn)。首先對原料蠶沙進行葉綠素提取率的測定，并將微波提取法與普通溶劑提取法進行比較。結(jié)論證明，微波提取法的提取率要比普通溶劑提取法的提取率高出一倍。其次考察了預(yù)處理過程中微波輻射時間、溶劑用量、溶劑與物料比例等因素的影響，確定初步的蠶沙萃取工藝條件，并優(yōu)化相關(guān)的工藝條件。在試驗范圍內(nèi)所得的數(shù)據(jù)表明:在微波輻射時間90s、破壁劑濃度40%、破壁助劑用量1：2(V[ml]:W[g]) 、提取溫度60min的條件下，提取效果最佳。最后，研究了所提取的葉綠素溶液皂化條件，并摸索了葉綠素銅鈉鹽的制取條件。發(fā)現(xiàn)分離操作中，溫度40℃、皂化60min效果明顯，在酸性pH值為2.4的條件下銅代的60min效果較好，得到的產(chǎn)品品質(zhì)也好。

Abstract: For rationally utilizing silkworm faeces，it was primarily researched in this article on the new processing of preparing sodium copper chlorophyllin from silk worm and the optimal processing faeces to coaching industry production. Firstly,some work has been done on the chlorophyll extraction rate from silkworm with two different method.The conclusion proves that the extraction rate of microwave assistant extacrtion is two times than the conventional one.In this study，the influence factors were studied including irradiated time，volume of solvent，co-agent proportion etc. during the microwave pretreatment procedure.And by these investigations，tussah extracted condition was determined and optimiezd. The results indicated best that under the following conditions:irradiaetd time 90s，the concentration of cell wall crack agent 40%，the ratio of material and cell wall crack agent is 1：2(V[ml]:W[g])，extracted temperature 60℃.Lastly，the operating conditions were found for chlorophyll solvent separation and chlorophyllin-copper-sodium preparation. The excellent Saponification effect can be obtained under the following parameters:tempeartuer 40 saponated time 60min; Under the acidity condition，the yieldis higher after 60 min copper exchanged reaction.
Keywords：silkworm；microwave assistant extraction; metalloporphyrin
