目前在(zai)國際(ji)上(shang)(shang)(shang)已經(jing)開(kai)(kai)發并驗(yan)證(zheng)了(le)(le)一種(zhong)(zhong)突(tu)破性(xing)(xing)(xing)(xing)的(de)(de)定(ding)量(liang)LC-MS方法(fa),用于(yu)物(wu)(wu)種(zhong)(zhong)特異性(xing)(xing)(xing)(xing)測定(ding)明(ming)(ming)膠(jiao)。這種(zhong)(zhong)所(suo)謂的(de)(de)可(ke)(ke)靠地(di)(di)檢(jian)測明(ming)(ming)膠(jiao)中(zhong)的(de)(de)豬和(he)牛成分,發表在(zai)食品(pin)化學雜志上(shang)(shang)(shang)。明(ming)(ming)膠(jiao)是許多(duo)食品(pin)和(he)藥物(wu)(wu)應(ying)用中(zhong)的(de)(de)有價(jia)值的(de)(de)成分,例如(ru)糖(tang)果,乳(ru)制(zhi)(zhi)(zhi)品(pin),肉制(zhi)(zhi)(zhi)品(pin)和(he)凝膠(jiao)膠(jiao)囊。明(ming)(ming)膠(jiao)的(de)(de)來源對消費者和(he)制(zhi)(zhi)(zhi)造商(shang)來說很(hen)重要。使用TrustGel™方法(fa),明(ming)(ming)膠(jiao)的(de)(de)物(wu)(wu)種(zhong)(zhong)真實性(xing)(xing)(xing)(xing)可(ke)(ke)以明(ming)(ming)確地(di)(di)證(zheng)明(ming)(ming)0.05%的(de)(de)定(ding)量(liang)限。在(zai)過去幾(ji)年中(zhong),明(ming)(ming)膠(jiao)制(zhi)(zhi)(zhi)造商(shang)在(zai)原(yuan)(yuan)材(cai)料的(de)(de)可(ke)(ke)追溯性(xing)(xing)(xing)(xing)方面付出(chu)了(le)(le)很(hen)多(duo)努力。諸如(ru)PCR和(he)ELISA的(de)(de)技術通常用于(yu)追蹤這些(xie)原(yuan)(yuan)料。然而(er),關(guan)于(yu)這些(xie)方法(fa),已經(jing)觀(guan)察到市售試(shi)劑(ji)盒的(de)(de)假陽(yang)性(xing)(xing)(xing)(xing)和(he)陰性(xing)(xing)(xing)(xing)結果,不一致性(xing)(xing)(xing)(xing)和(he)低反(fan)應(ying)性(xing)(xing)(xing)(xing)。使用TrustGel™方法(fa),明(ming)(ming)膠(jiao)制(zhi)(zhi)(zhi)造商(shang)現在(zai)可(ke)(ke)以確定(ding)關(guan)于(yu)牛和(he)豬成分的(de)(de)明(ming)(ming)膠(jiao)批(pi)次的(de)(de)純(chun)度(du)。驗(yan)證(zheng)實驗(yan)裝(zhuang)置基于(yu)FDA和(he)EMA生物(wu)(wu)分析方法(fa)驗(yan)證(zheng)指南(nan),并根據良好實驗(yan)室(shi)規范(fan)進行,確保(bao)科學質量(liang),可(ke)(ke)追溯性(xing)(xing)(xing)(xing)和(he)數(shu)據完整(zheng)性(xing)(xing)(xing)(xing)。目前國際(ji)上(shang)(shang)(shang)有公司開(kai)(kai)始一起啟動了(le)(le)該項(xiang)目,并支(zhi)持(chi)該方法(fa)的(de)(de)開(kai)(kai)發。基于(yu)TrustGel TM方法(fa)的(de)(de)明(ming)(ming)膠(jiao)測試(shi)服務(wu)是商(shang)業上(shang)(shang)(shang)可(ke)(ke)獲得購買。
明膠的來源對消費者和制造商來說很重要
