Research on porphyrin-Copper-Sodium separate from silkworm
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.
