Kuyambira 1980s, powona kuchepa kwa makampani a Silika a ku Japan, kafukufuku wokhudza gawo latsopano a Silika pang'onopang'ono wakopa chidwi cha anthu. Kukhazikitsidwa pokonzekera silika Fibroin, mitundu yopanga fiberin, mawonekedwe, komanso muukadaulo wa zamankhwala, pulogalamu ya Enzyme, chakudya, kuteteza khungu kuti mulawe mwachangu ntchitoyo mwachangu. Kufikira kumapeto kwa 80 s, protein ya silika mu chakudya, ntchito zachisamaliro za khungu zafika.
Chitetezo cha mapuloteni silika pakugwiritsa ntchito
Mafuta opanga zakudya zopatsa mphamvu zogwiritsidwa ntchito pazinthu zomwe zimagwiritsidwa ntchito pakhungu ndi nyama zambiri zimatulutsa ndi mapuloteni a silika. Ambiri mwa omwe amapezeka akumanja amapangidwa ndi Bovine ndi Strenta, omwe amapezeka ndi enzymatic chiwopsezo. Kupangidwa kwake kumakhala kovuta kwambiri ndipo kumakhala zinthu zina zothandizira kwa thupi, kotero palinso zifukwa zakusiririka. Poona zaka zaposachedwa mayiko ena padziko lapansi amapezeka m'manda ndi nthenda yam'madzi, kuyambira pa Marichi 2000, nyumba zapakhomo zaletsa zomwe zili ndi zinyama zodzikongoletsera.
Mapulotetetein ambiri amataya cocoon ngati zopangira, kupatula zitsulo zolemera komanso zinthu zina zolimbitsa thupi zomwe zimapweteketsa thupi. Amakonda kuphatikizidwa ndi zipolopolo. Mothandizidwa ndi purotein ya silika, siyikukhudzanso thupi.
Kaya sikek fibroin mapuloteni amatha kuteteza khungu ndikudya
Ambiri mwa mayunitsi am'nyumba, achita kuyezetsa chitetezo. Mu 1998, Zhejiang Silkworm kafukufuku ku Institute adagwira ntchito yolimbikitsa "zotola zokhala ndi silika zoyeserera, zomwe zimayesedwa ndi mayeso akhungu ndi mayeso a khungu. Zinatsimikiziridwa kuti malondawo sanali toixic, osakwiyitsa komanso osakhala khungu. Shaanxi Aggie etc, kuyesanso kwa silika kwa chakudya cham'mimba, malinga ndi pulogalamu yoyeserera yazakudya zowunikira za chakudya, pachiwopsezo chaidenti choyimira, silika zovulaza.
Zitha kunenedwa kuti silika Fibroin ndi wathanzi, wotetezeka komanso wopanda vuto zikagwiritsidwa ntchito mu chakudya ndi zodzoladzola.
