Lub luag hauj lwm ntawm lub hnab ntim nqus
1. cov luag hauj lwm tseem ceeb yog raug tshem tawm ntawm cov pa
Qhov tseeb, qhovnqus tsev ntimtshuab preservation tso tsi nyuab, yog ib qhov tseem ceeb tshaj qhov tshem cov pa mus hauv lub ntim tshuaj no. Cov hnab thiab cov zaub mov hauv cov pa ua tawm, thiab mam li ntim ntim, kom tsis txhob huab cua rau cov oxidation, cov tshuaj tiv thaiv yuav tsis pom, sij cuag cov nyhuv ntawm preservation. Yog siv cov tshuab nqus ntim kom tsis txhob muaj khoom noj khoom haus deterioration conducive, yog vim muaj zaub mov pwm rot mas tshwm sim los ntawm kev ua microbial, cov ciaj sia taus cov kab mob uas feem ntau yog cov xav tau cov pa, nqus ntim yog siv no tso, twj tawm los ntawm qhov hnab thiab zaub mov, cov pa kom kab mob micro poob nyob ib puag ncig. Ntim nqus tau tsis inhibit lub proliferation co kab thiab enzyme tshua los yog khoom noj khoom haus deterioration heev, thiab vim li no yuav tsum kom tau tag nrho nrog rau lwm cov kev uas ntu, xws li nyob, quick-frozen, cev qhuav, High School-kub kom tsis muaj menyuam, tawg kom tsis muaj menyuam, microwave kom tsis muaj menyuam, salt ua luaj rau.
2. yuav tiv thaiv cov zaub mov oxidation
Roj thiab cov yam muaj coob leej unsaturated fatty acids, pa mus rau ntawm oxidation, khoom noj khoom haus saj hloov, deterioration. Ntxiv mus, tus oxidation ntawm vitamin A thiab vitamin C yuav zaub mov coloring tej yam hauv lub luag hauj lwm tsis ruaj tsis khov tej los ntawm cov pa, kom xim dimmed. Vim li no, tshem cov pa no kom zaub deterioration, mus kho nws cov xim, tsis hnov tsw, saj zoo.
3. cov tshuab txuas
Tshuab nqus ntim, tus loj luag hauj lwm rau kev nqus ntim uas muaj cov yam ntxwv deoxidation txee-lub neej, yog muaj compression, roj kuj, preservation thiab lwm yam teebmeem, yuav ntau zoo ua noj ua haus kom muaj tus thawj xim, tsis hnov tsw, saj, zoo lawm thiab zoo mus ntev. Ntxiv thiab, muaj ntau yam khoom noj txhob siv nyob rau hauv lub tshuab nqus tsev ntim, thiab yuav tsum siv tshuab inflatable packaging. Xws li crispy taus mov, yooj yim rau agglomerate zaub mov, yooj yim muaj tsis txhua muab roj zaub mov, ntse hau thiab fab los yog ntau dua hardness yuav hno cov hnab khoom noj khoom haus. Khoom noj khoom haus nqus plua plav packing tshuab nqus khoom ntim, lub hnab ntim tshuab packing hnab siab ib yam li cov atmospheric siab, zoo kom lub siab crushing deformation zaub mov, tsis muaj dabtsi yuav pom lub hnab thiab luam ntawv thiab decorating.
Lub tshuab nqus tsev packednyob rau hauv ib lub tshuab nqus tsev thiab ces kam nrog nitrogen, carbon dioxide, pa, ib zaug xwb roj los yog 2-3 yam sib tov sib xyaw roj. Thaum cov nitrogen uas yog ib inert gas, los ntawm tus sau nyhuv, kom lub hnab kom muaj kev zoo siab los tiv thaiv lub hnab nyob nraum zoov cua mus rau hauv lub hnab, cov khoom ua si ib tug tiv. Pa roj carbon dioxide tau neej hauv kheev muaj ntau hom roj los dej, tsis muaj zog acidity ntawm carbonic acid, qhov uas muaj inhibit pwm, txhob lwj kab thiab lwm yam kev ua microbial. Cov pa muaj inhibited txoj kev loj hlob thiab kev tu tub tu kiv co kab mob kom txhob muaj txiv hmab txiv ntoo thiab zaub tshiab thiab xim, END pa yuav ua rau cov nqaij kom muaj qhov liab ploog.
