1.2 Kev siv hauv cov khoom hauv dej
Cov ntses tsis hnov tsw yog feem ntau trimethylamine. Hauv kev sim deodorization, trimethylamine thiab kua polyphenols tau sib xyaw, thiab cov nqi ntawm trimethylamine tsis hloov pauv tau ntsuas siv cov roj chromatograph. Nws tau pom tias raws li qhov concentration ntawm cov kua txiv hmab txiv ntoo polyphenols nce, tus nqi ntawm cov volatile trimethylamine nce. Tus nqi ntawm amines tseem txo qis. Thaum cov ntsiab lus ntawm cov kua polyphenols yog 200 ug / mL, tus nqi ntawm cov tshuaj trimethylamine tuaj yeem txo los ntawm 50%. Hauv kev ua cov khoom lag luam hauv dej, tom qab herring thiab cov nqaij ntses liab kho nrog kua polyphenols tau khaws cia ntawm 4 degree rau 2 hnub, nws pom tias cov xim ntawm cov nqaij ntses hauv pawg tswj hwm tau hloov pauv ntau thiab cov nqaij tig daj, thaum cov ntses. ntxiv nrog kua polyphenols tseem khaws cov xim tom qab 10 hnub. Zoo dua tshiab.
1.3 Daim ntawv thov hauv cov pos hniav
Ua tsis taus pa yog tshwm sim los ntawm ntau yam. Lub ntsiab tseem ceeb ntawm kev ua pa phem yog methylmercaptan uas ua los ntawm sulfur-muaj amino acids. Hauv kev sim deodorization, sulfur-muaj methionine tau siv los ua cov matrix, tib neeg cov qaub ncaug uas muaj cov kab mob hauv qhov ncauj tau ntxiv, thiab methylmercaptan tau tsim ntawm 37 degree. Thaum 300 ug/mL ntawm cov kua polyphenols tau ntxiv rau hauv matrix, kev tsim cov methyl mercaptan raug txo los ntawm ntau dua 50%. Thaum cov nyiaj ntxiv tau nce mus txog 1200 ug / mL, kev tsim cov methyl mercaptan tau inhibited kiag li. Hauv kev sim tib neeg, nws tau ua nyob rau hauv daim ntawv ntawm cov pos hniav. Thaum zom cov pos hniav uas tsis muaj cov kua polyphenols, cov ntsiab lus methyl mercaptan hauv lub qhov ncauj pib nce tam sim ntawd tom qab zom; zom cov pos hniav uas muaj 0.25% ntawm cov kua polyphenols, 30 feeb tom qab Methyl mercaptan pib nce; Cov ntsiab lus ntawm cov kua polyphenols nce mus txog 0.5%, thiab methyl mercaptan pib nce 60 feeb tom qab zom. Yog li, cov kua txiv polyphenols muaj cov txiaj ntsig zoo hauv inhibiting ua pa tsis zoo thiab tuaj yeem siv rau hauv kev zom cov pos hniav. Nyiv muaj cov khoom lag luam sau npe.
1.4 Kev siv hauv cov khoom noj tsiaj txhu
Sib tov cov nqaij npuas hauv mincer, faib ua 3 qhov qauv, ntxiv 10% dej-soluble polyphenols, 0.4% roj-soluble polyphenols, thiab 0.1% hluavtaws tocopherol, 70% loj, hauv ua ntu zus ntawm 70 degree. Tom qab cua sov kom tsis muaj menyuam rau 40 feeb, khaws cia ntawm 1 degree, thiab thaum kawg ntsuas nws cov tsos thiab tus nqi peroxide. Cov txiaj ntsig tau pom tias cov txiaj ntsig ntawm kev siv polyphenols zoo dua li cov tocopherols, thiab cov roj-soluble polyphenols muaj kev sib raug zoo rau cov nqaij zoo dua li hydrophilic polyphenols. Kua polyphenols kuj tseem siv tau los khaws cov nqaij braised. Los ntawm kev sib xyaw nrog lwm cov tshuaj antioxidants los tsim ib hom tshiab ntawm braised nqaij preservative, cov nqaij braised tuaj yeem coated los khaws nws cov freshness, uas txhim kho cov antioxidant zog ntawm braised nqaij thiab txuas lub neej txee.
1.5 Kev siv dej cawv thiab dej haus
Kua polyphenols tuaj yeem siv los ua tus neeg sawv cev qhia meej rau cawv thiab dej haus. Lawv tsuas yog siv phenolic hydroxyl pawg los txuas rau cov pab pawg amide hauv cov proteins los ntawm hydrogen bonds, uas tuaj yeem ua rau cov gelatin thiab tannins tsim cov complexes rau aggregate thiab precipitate, thiab tib lub sij hawm ntes thiab tshem tawm lwm yam tshuaj raug tshem tawm. khov kho. Ntxiv 0.05% txiv apple polyphenols rau vitamin C tov nrog ib tug loj feem ntawm 1 × 10E-3 tuaj yeem inhibit qhov degradation ntawm vitamin C, thiab nws muaj zog inhibitory nyhuv ntawm pigment fading, tshwj xeeb tshaj yog ntawm carotene pigments. Cov kws tshawb fawb ntxiv 1% kua polyphenols rau cov dej qab zib uas muaj -carotene thiab capsanthin los tswj lawv cov xim ci thaum lub sijhawm txee lub neej.
2. Daim ntawv thov hauv tshuaj pleev ib ce
Kua polyphenols yog ib yam khoom ntuj tsim nrog tshwj xeeb physiological thiab tshuaj ua si. Nws muaj zoo astringency thiab adhesion. Nws muaj peev xwm tswj tau cov synthesis ntawm collagen, inhibit elastase, pab lub cev tiv thaiv collagen thiab txhim kho daim tawv nqaij elasticity, yog li zam los yog txo qhov tshwm sim ntawm wrinkles thiab tuav lub ilv tsos ntawm daim tawv nqaij.

Tsis tas li ntawd, vim tias cov tshuaj phenolic tuaj yeem cuam tshuam cov haujlwm ntawm tyrosinase thiab catalase thiab tshem tawm cov pa oxygen reactive, lawv tuaj yeem siv los npaj cov vitamin C lossis vitamin E polyphenol complex whitening agents. Cov kws tshawb fawb los ntawm University of Finland tau ua nyob rau hauv vitro thwmsim rau ntawm daim tawv nqaij uas raug ultraviolet lub teeb los ntawm ib tug cytological foundations thiab pom tias thaum tib neeg daim tawv nqaij raug rau ultraviolet zog rau 30 feeb xwb, tshav ntuj tua txog 50% ntawm lub hlwb. Nrog rau qhov sib ntxiv ntawm oligomeric proanthocyanidins, kwv yees li 80% ntawm cov hlwb raug tua. Cov tawv nqaij tawv raug tiv thaiv los ntawm kev puas tsuaj thiab muaj UV nqus tau zoo dua piv rau vitamin C.
Apple polyphenol prospects
