APPLICATION ya WATER RETAINING AGENT mu MEAT PRODUCTS

Wothandizira kusunga chinyezi amatanthauza gulu la zinthu zomwe zingapangitse kukhazikika kwa chinthucho, kusunga mphamvu yamkati ya madzi a chakudya, ndikuwongolera mawonekedwe, kukoma, mtundu, ndi zina za chakudya panthawi yokonza chakudya. kuthandizira kusunga chinyezi m'zakudya makamaka kumatanthauza ma phosphates omwe amagwiritsidwa ntchito pokonza nyama ndi zam'madzi kuti apititse patsogolo chinyontho chawo komanso kukhala ndi madzi okwanira.

Phosphate ndiye nyama yokhayo ya humectant yomwe imatha kuyambitsa mapuloteni a nyama popanga nyama.Kupanga ndi kukonza nyama sikusiyanitsidwa ndi phosphate.Phosphate imagawidwa m'magulu awiri, mankhwala a monomer ndi mankhwala apawiri.

Zogulitsa za monomer: zimatanthawuza ma phosphates otchulidwa mu GB2760 Food Additive Use Standards monga sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, ndi trisodium phosphate.

Zogulitsa za monomer: zimatanthawuza ma phosphates otchulidwa mu GB2760 Food Additive Use Standards monga sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, ndi trisodium phosphate.

1. Njira ya Phosphate Yothandizira Kusunga Madzi a Nyama:

1.1 Sinthani pH ya nyama kuti ikhale yokwera kuposa isoelectric point (pH5.5) ya mapuloteni a nyama, kuti nyamayo isasungidwe bwino ndikuonetsetsa kuti nyamayo yakhala yatsopano;

1.2 Kuonjezera mphamvu ya ionic, yomwe imakhala yopindulitsa pakutha kwa mapuloteni a myofibrillar, ndipo imapanga dongosolo la intaneti ndi mapuloteni a sarcoplasmic mogwirizana ndi mchere, kuti madzi asonkhanitsidwe mumtundu wa maukonde;

1.3 Ikhoza chelate ayoni zitsulo monga Ca2+, Mg2+, Fe2+, kusintha madzi posungira ntchito, ndipo nthawi yomweyo kusintha antioxidant zotsatira, chifukwa ayoni zitsulo ndi activators wa makutidwe ndi okosijeni mafuta ndi rancidity.Chelation ya mchere, magulu a carboxyl mu mapuloteni a minofu amamasulidwa, chifukwa cha kutengeka kwa electrostatic pakati pa magulu a carboxyl, mapangidwe a mapuloteni amakhala omasuka, ndipo madzi ambiri amatha kuyamwa, potero kumapangitsa kuti madzi asasungidwe;

Pali mitundu yambiri ya phosphates, ndipo zotsatira za chinthu chimodzi nthawi zonse zimakhala zochepa.N'zosatheka kugwiritsa ntchito phosphate imodzi pogwiritsira ntchito nyama.Nthawi zonse padzakhala zinthu ziwiri kapena zingapo za phosphate zosakanikirana ndi zinthu zambiri.

2. Momwe mungasankhire wothandizira kusunga chinyezi:

2.1 Zogulitsa zomwe zili ndi nyama zambiri (zoposa 50%): Nthawi zambiri, zinthu zopangidwa ndi phosphate yoyera zimagwiritsidwa ntchito, ndipo kuchuluka kwake ndi 0.3% -0.5%;

2.2 Zogulitsa zokhala ndi nyama yotsika pang'ono: Nthawi zambiri, kuchuluka kwake ndi 0.5% -1%.Zogulitsa zoterezi nthawi zambiri zimaphatikizidwa ndi ntchito zapadera monga ma colloids kuti awonjezere kukhuthala ndi kugwirizanitsa kwa kudzazidwa;

3. Mfundo zingapo posankha zinthu za humectant:

3.1 Kusungunuka kwa mankhwala, wothandizira kusungirako angagwiritsidwe ntchito pokhapokha atasungunuka, ndipo mankhwala omwe ali ndi vuto losasunthika sangathe 100% kutenga nawo mbali;

3.2 Kuthekera kwa kudzaza nyama yamchere kuti isunge madzi ndikukulitsa mtundu: Pambuyo podzaza nyama ndi marinated, idzakhala ndi elasticity, ndipo kudzazidwa kwa nyama kudzakhala ndi kuwala;

3.3 Kukoma kwazinthu: ma phosphates okhala ndi chiyero chosakwanira komanso osakhala bwino amakhala ndi astringency akapangidwa kukhala nyama ndikulawa.Chiwonetsero chodziwikiratu chili kumbali zonse ziwiri za muzu wa lilime, ndikutsatiridwa ndi tsatanetsatane monga kutsekemera kwa kukoma kwa mankhwala;

3.4 Kutsimikiza kwa mtengo wa PH, PH8.0-9.0, alkalinity yamphamvu kwambiri, kutenthetsa kwambiri kwa nyama, zomwe zimapangitsa kuti thupi likhale lotayirira, osati magawo okhwima, kusakhazikika bwino;

3.5 Chowonjezera chophatikizika chimakhala ndi kukoma kwabwino komanso kogwirizana bwino, kupeŵa kuipa kwa chinthu chimodzi monga kukoma kwa astringent, kusungunuka bwino, mpweya wamchere, ndi zotsatira zosafunikira;
