Kuwonjezeraphosphates kuzinthu za nyama zimatha kusintha kapangidwe kake, kuonjezera kusungidwa kwa madzi ndi zokolola za mankhwala, ndikuwongolera kapangidwe ka nyama, potero kuchepetsa mtengo wazinthu popanda kuchepetsa mtundu wa chinthucho. (1) Wonjezerani pH mtengo wa nyama; (2) Chelate zitsulo ayoni mu nyama; (3) Wonjezerani mphamvu ya ionic ya nyama; (4) Olekanitsa actomyosin.
Tripolyphosphate ndi pyrophosphate akhoza kuonjezera mphamvu ya ayoni ya dongosolo nyama ndi kusintha mphamvu ya magetsi a mlandu mapuloteni, ndi kupatuka pa mfundo isoelectric, kotero kuti milandu kuthamangitsana wina ndi mzake ndi kupanga danga lalikulu pakati pa mapuloteni, ndiko kuti, mapuloteni "Kutupa" kwa minofu ya nyama kumatha kukhala ndi madzi ochulukirapo kuti apititse patsogolo kusunga madzi; hexametaphosphate imatha chelate ayoni zitsulo, kuchepetsa kuphatikiza kwa ayoni zitsulo ndi madzi, ndikupanga mapuloteni kuti amange madzi ochulukirapo kuti madzi asungidwe bwino. Zochita zatsimikizira kuti kugwiritsa ntchito kosakanikirana kosiyanasiyanaphosphates Ndikwabwino kuposa kugwiritsa ntchito kamodzi, kosakanikiranaphosphates nthawi zambiri amagwiritsidwa ntchito kuonjezera zotsatira. Paguluphosphate ndi zamchere, zomwe zimatha kuonjezera pH mtengo wa nyama ndikulimbikitsa mphamvu ya calcium activating enzyme pa nyama. Pa nthawi yomweyo, kompositiphosphate ali ndi milandu yambiri yolakwika, komanso yotsika kwambiri ya kompositiphosphate imatha kuonjezera mphamvu ya ayoni ya yankho, kotero imatha chelate ayoni zitsulo, monga magnesium, zinki, ndi zina zambiri, ndikuwulula puloteni-COO-terminal Imathandizira kuthamangitsidwa kwa nyama, kumasula nyama, ndikuwonjezera kufatsa. wa nyama.
Popeza chifundo cha nyama chikugwirizana ndi zili connective minofu ndi myofibril kwambiri kolajeni mtanda maulalo mu connective minofu, kuipa kwambiri mwachifundo nyama. Pambuyo powonjezera phosphate zovuta, zimatha kuwonjezera kusungunuka kwa kolajeni, kuchepetsa kulumikizana kwa collagen mu minofu yolumikizana, ndikuwongolera kufatsa kwa nyama.
Kophatikiza phosphate imathanso kulekanitsa actomyosin, kuchepetsa kuuma kwa minofu, ndikusintha kukoma kwa nyama. Chiŵerengero cha pawiriphosphate ndi: tripolyphosphate: pyrophosphate: hexametaphosphate-2: 2: 1, ndipo pamene kuchuluka kwake ndi 0.5%, zotsatira za tenderization pa nyama ya ng'ombe ndi kalulu ndizo zabwino kwambiri. Ndikoyenera kugwiritsa ntchito jekeseni marinating kwa maola 16. Aphosphate enzyme yowola muzakudya za nyama imawolaphosphate ndi kuchipanga kukhala chosathandiza. Chifukwa chake, popanga zinthu za nyama, chidwi chapadera chiyenera kuperekedwa pakusankha zowonjezera njira zoyenera kupewa kuwononga zotsatira zaphosphate. Nthawi zambiri, popanga ndi kukonza nyama, nthawi zambiri zimakhala bwino kuzigwiritsira ntchito pogubuduza ndi kusakaniza pambuyo pa marinating; palinso njira yogwiritsira ntchito njira yothetsera marinating. Panthawi imodzimodziyo, zimaganiziridwa kuti kuwonjezereka kwa phosphate kumawononga kukoma ndi mtundu wa mankhwala, ndipo sikuli bwino kwa thanzi laumunthu.
Chitetezo chaphosphate:
Phosphate ndi gawo logwira mtima la minofu yaumunthu, monga mano, mafupa ndi michere, ndipo imagwira ntchito yofunika komanso yofunika kwambiri pa metabolism yazakudya zofunika monga shuga, mafuta, ndi mapuloteni. Chifukwa chake,phosphate nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera chopatsa thanzi. Koma pamene aphosphate Zomwe zili muzakudya ndizochuluka kwambiri, zidzachepetsa kuyamwa kwa calcium, zomwe zimapangitsa kuti calcium iwonongeke m'mafupa aumunthu. Ngati zimatenga nthawi yayitali, zimatha kuyambitsa kuchedwa kwachitukuko komanso kupunduka kwa mafupa. Chifukwa chake, ma phosphates ayenera kuwonjezeredwa ndikugwiritsidwa ntchito mosamalitsa mkati mwa momwe boma likugwiritsidwira ntchito.

"Kampani yathu inkachita msika wapakhomo kokha. Poyambitsa ndondomeko zabwino monga kugula msika ndi njira zamalonda, tsopano zinthu zomwe kampaniyo imagulitsa kunja zimakhala ndi 1/3 ya zonse zomwe zimachokera." Zhang Jie, manejala wamkulu wa Linyi Youyou Household Products Co., Ltd. adauza atolankhani, Linyi Mall Amalonda ambiri omwe amayang'ana kwambiri malonda apanyumba ayamba kuyesa molimba mtima kuti atsegule misika yakunja.
Zotsatira zabwino za "kutuluka" kwamabizinesi "zikuyenda bwino" m'dziko la Qilu. Pa November 12, SCO Demonstration Zone Certificate of Origin Examination and Signing Center inatsegulidwa mwalamulo ku Qingdao, Province la Shandong. Likululi limadziwika ndi mgwirizano wachuma ndi malonda wa mayiko omwe ali mamembala a SCO, kulola kuti katundu waku China asangalale ndi zomwe amakonda akamatumizidwa kunja.
"Kuphatikizana mwakhama pomanga 'Belt ndi Road' kwapereka malingaliro atsopano pa chitukuko cha malonda akunja a Shandong ndikutsegula misika yatsopano." adatero Zheng Shilin, wofufuza pa Institute of Quantitative and Technical Economics ya Chinese Academy of Social Sciences.
