2. Yanke ko rage girman don ƙara girman saman da kuma sa fitar da shi ya fi inganci.
3. Ajiyewa a cikin sanyi (a sanyaya ko a daskare) idan ba a sarrafa shi nan da nan ba, don kiyaye ingancin collagen.
Tsaftace tsari yana da matuƙar muhimmanci domin galibi ana amfani da collagen a cikin kayayyakin da suka taɓa jiki ko kuma aka sha, don haka ya kamata a tsaurara ƙa'idojin tsafta da kuma kula da gurɓata.
Rage mai da kuma rage furotin
Kayan aiki kamar fatar kifi suna ɗauke da kitse waɗanda za su iya tsoma baki wajen cirewa, haifar da wari, da kuma hanzarta ƙonewa. Saboda haka, ana yin rage mai (cire kitse), misali ta hanyar jiƙa shi a cikin takamaiman sinadarai masu narkewa na abinci ko hanyoyin enzyme na ruwa/lipase, ya danganta da yadda ake amfani da shi da ƙa'idodi.
Sannan ana yin cire furotin daga jiki don rage sunadaran da ba na collagenous ba. Hanyar da aka saba amfani da ita ta kunshi nutsewa cikin ruwan alkaline mai narkewa (misali, NaOH mai ƙarancin maida hankali) na tsawon sa'o'i da yawa zuwa kwanaki, tare da canza ruwan lokaci-lokaci. Wannan matakin yana taimakawa wajen narkar da sunadaran globular da pigments, amma dole ne a sarrafa shi sosai don gujewa lalata collagen.
Ƙarfin ...
Idan kayan da aka yi amfani da su a matsayin sikeli ko ƙashi, ana buƙatar rage ma'adanai don cire ma'adanai, musamman hydroxyapatite. Ana yin wannan tsari ne ta amfani da maganin acid mai rauni kamar EDTA ko Organic/inorganic acid a wasu yanayi. Ingantaccen rage ma'adanai yana haifar da ma'aunin collagen wanda ya fi sauƙin cirewa kuma yana inganta tsarkin samfurin.
Cire Collagen: Hanyoyin Acid da Enzyme
1. Cire Acid (ASC)
Fitar da sinadarin acid yawanci yana amfani da sinadarin acetic acid mai narkewa. Manufar ita ce a sassauta tsarin kyallen da ke hadewa, wanda hakan zai sa collagen ya fi narkewa. Ana gudanar da wannan tsari a yanayin zafi mai ƙanƙanta (galibi ƙasa da zafin da ke fitar da sinadarin collagen) don kiyaye tsarin helix mai sau uku. Bayan an jiƙa shi an kuma motsa shi na wani lokaci, ana tace ruwan da aka fitar ko kuma a sanya shi a cikin injin don raba ragowar da ke cikinsa.
Amfanin wannan hanyar shine sauƙinta da ƙarancin farashi. Duk da haka, yawan amfanin ƙasa na iya raguwa saboda sinadarin collagen mai haɗin gwiwa ba ya narkewa cikin sauƙi ta hanyar acid kaɗai.
2. Cirewar Enzyme da Aka Taimakawa (PSC)
A cikin hanyar PSC, ana ƙara enzyme pepsin a ƙarƙashin yanayin acidic. Pepsin yana taimakawa wajen raba yankunan da ba su da helical (telopeptides) waɗanda galibi suna aiki azaman wuraren haɗin gwiwa, yana ba da damar collagen ya narke cikin sauƙi. Wannan hanyar yawanci tana samar da mafi yawan amfanin ƙasa fiye da ASC kuma tana iya inganta daidaiton cirewa daga kayan da aka "tsofaffi" ko fiye da haɗin gwiwa.
Kalubalen da ke tattare da PSC sune farashin enzyme da kuma buƙatar sarrafa tsari don hana lalacewa mai yawa wanda ke rage inganci.
Tsarkakewa: Ruwan sama, Dialysis, da Busarwa
Da zarar an cire sinadarin collagen, mataki na gaba shine tsarkakewa. Hanya ɗaya da aka saba amfani da ita ita ce yin gishiri, ta amfani da gishiri (misali, NaCl) don fitar da sinadarin collagen daga ruwan. Sannan sai a raba sinadarin ta hanyar centrifugation sannan a sake narkar da shi a cikin wani sinadari mai narkewar acid.
Bayan haka, ana yin dialysis don cire gishiri, acid, da sauran ƙananan ƙwayoyin halitta. Dialysis yana ɗaukar kwanaki da yawa, tare da canza ruwa ko ma'aunin ruwa akai-akai. Mataki na ƙarshe shine bushewa, yawanci ana amfani da busarwa da daskarewa don kula da tsarin collagen da kuma samar da foda mai ƙarfi.
A fannin masana'antu, ana iya yin busarwa ta hanyar feshi, amma dole ne a tsara shi ta yadda zafin aikin ba zai lalata collagen ko kuma ya haifar da yawan denaturation ba.
Samar da sinadarin Collagen Peptide (Hydrolysis)
Domin samar da peptides na collagen, ana cire collagen ko kuma a yi amfani da sinadarin hydrolyzed na ɗanyen collagen ta amfani da takamaiman enzymes na protease. Tsarin hydrolysis yana samar da ƙananan peptides masu narkewa tare da ɗanɗano da launi mafi tsaka tsaki idan an tsarkake su yadda ya kamata. Waɗannan peptides ana amfani da su sosai a cikin abubuwan sha, kari, da abubuwan haɗin abinci.
