Ibicuruzwa bishya Glucono-delta-lactone
Colorkem yatangije ibiryo bishya byongera ibiryo: Glucono-delta-lactone ku ya 20. Nyakanga, 2022. Glucono-delta-lactone mu magambo ahinnye yitwa lactone cyangwa GDL, naho formulaire ya molekile ni C6Hl0O6. Ibizamini byuburozi byerekanye ko ari ibintu bidafite uburozi biribwa. Ifu yera ya kirisiti cyangwa ifu yera ya kirisiti, hafi idafite impumuro nziza, ubanza kuryoshya hanyuma ikarishye muburyohe. gushonga mu mazi. Glucono-delta-lactone ikoreshwa nka coagulant, cyane cyane mu gukora tofu, ndetse no nka protein coagulant ku bicuruzwa by’amata.
Ihame
Ihame rya glucoronolide coagulation ya tofu ni uko iyo lactone yashongeshejwe mumazi mo aside ya gluconique, aside igira ingaruka kuri acide kuri proteyine mumata ya soya. Kuberako kubora kwa lactone bitinda cyane, reaction ya coagulation irasa kandi nubushobozi buri hejuru, tofu yakozwe rero yera kandi yoroshye, nziza mugutandukanya amazi, irwanya guteka no gukaranga, biryoshye kandi byihariye. Ongeramo izindi coagulants nka: gypsum, brine, calcium chloride, ibirungo bya umami, nibindi, birashobora kandi gukora tofu zitandukanye.
Koresha
1. Tofu coagulant
Gukoresha glucono-delta-lactone nka protein coagulant kugirango itange tofu, imiterere yera kandi yuzuye ubwuzu, nta gusharira no gukomera kwa brine gakondo cyangwa gypsumu, nta gutakaza poroteyine, umusaruro mwinshi wa tofu, kandi byoroshye gukoresha.
Urebye ko iyo GDL ikoreshejwe wenyine, tofu iba ifite uburyohe buke, kandi uburyohe busharira ntibukwiriye tofu, bityo GDL na CaSO4 cyangwa izindi coagulants zikoreshwa kenshi muguhuza umusaruro wa tofu. Nk’uko raporo zibitangaza, iyo zitanga tofu nziza (ni ukuvuga tofu yoroshye), igipimo cya GDL / CaSO4 kigomba kuba 1 / 3-2 / 3, amafaranga yiyongereye agomba kuba 2,5% yuburemere bwibishyimbo byumye, ubushyuhe bugomba kugenzurwa kuri 4 ° C, kandi umusaruro wa tofu ugomba kuba wumye. Inshuro 5 uburemere bwibishyimbo, kandi ubwiza nabwo ni bwiza. Ariko, hariho ibibazo bimwe na bimwe bikwiye kwitonderwa mugihe ukoresheje GDL gukora tofu. Kurugero, gukomera no guhekenya tofu bikozwe muri GDL ntabwo ari byiza nkibya tofu gakondo. Byongeye kandi, ubwinshi bwamazi yo gukaraba ni make, kandi proteyine ziri mu bishyimbo byibishyimbo zabuze byinshi.
2. Umukozi wo gutanga amata
GDL ntabwo ikoreshwa gusa nka protein coagulant yo gukora tofu, ahubwo ikoreshwa nka protein coagulant yo gukora proteine y’amata yogurt na foromaje. Ubushakashatsi bwerekanye ko imbaraga za gel zamata yinka zatewe na acide hamwe na GDL zikubye inshuro 2 ubwoko bwa fermentation, mugihe imbaraga za yogurt yogurt yakozwe na acide hamwe na GDL yikubye inshuro 8-10 zubwoko bwa fermentation. Bizera ko impamvu itera imbaraga nke za gel yogurt yogurt ishobora kuba kwivanga mubintu bitangira (biomass na selile polysaccharide) kumikoranire ya gel hagati ya proteyine mugihe cya fermentation. Ubushakashatsi bumwe na bumwe bwerekanye kandi ko amata y’amata akorwa na aside yongeramo 3% GDL kuri 30 ° C afite imiterere isa na gel ikorwa na fermentation ya bacteri acide lactique. Biravugwa kandi ko kongeramo 0,025% -1.5% GDL ku mata y’inyamanswa bishobora kugera ku mbuto zisabwa pH, kandi iyongeweho ryihariye riratandukanye n’ibinure birimo amata y’inyana n'ubushyuhe bwo kubyimba.
3. Iterambere ryiza
Gukoresha GDL mu nyama za sasita hamwe ningurube zafunzwe birashobora kongera ingaruka zumukozi wamabara, bityo bikagabanya urugero rwa nitrite, ifite uburozi bwinshi. Kubwiza bwibiryo byafunzwe, umubare ntarengwa wongeyeho muri iki gihe ni 0.3%. Byavuzwe ko kwiyongera kwa GDL kuri 4 ° C bishobora kuzamura ubukana bwa fibrilline, kandi kwiyongera kwa GDL bishobora kongera ubukana bwa gel, haba imbere ya myosine na myosine cyangwa imbere ya myosine yonyine. imbaraga. Byongeye kandi, kuvanga GDL (0.01% -0.3%), aside aside (15-70ppm) hamwe na estride ya acide acide (0.1% -1.0%) mumigati irashobora kuzamura ubwiza bwumugati. Kongera GDL mubiryo bikaranze birashobora kubika amavuta.
4. Kurinda ibintu
Ubushakashatsi bwa Saniea, marie-Helence n'abandi. yerekanye ko GDL ishobora gutinda no guhagarika umusaruro wa bagiteri ya acide lactique, bityo bigatuma imikurire isanzwe niyororoka rya bagiteri ya acide lactique. Ongeramo urugero rukwiye rwa GDL kumata birinda ihungabana riterwa na fage mubicuruzwa bya foromaje. Qvist, Sven n'abandi. yize ku miterere yo kubungabunga GDL muri sosiso nini itukura, asanga kongeramo 2% acide lactique na 0,25% GDL ku bicuruzwa bishobora kubuza neza gukura kwa Listeria. Ingero nini zitukura za sausage zatewe na Listeria zabitswe kuri 10 ° C muminsi 35 nta mikorobe ikuze. Ingero zidafite imiti igabanya ubukana cyangwa lacate ya sodium gusa zabitswe kuri 10 ° C kandi bagiteri yakura vuba. Ariko, birakwiye ko tumenya ko mugihe ingano ya GDL ari myinshi, abantu barashobora kumenya umunuko uterwa nayo. Biravugwa kandi ko gukoresha GDL na sodium acetate ku kigereranyo cya 0.7-1.5: 1 bishobora kongera igihe cyo kuramba no gushya kwumugati.
5. Acide
Nka acide, GDL irashobora kongerwamo sherbet nziza na jelly nkibikomoka kuri vanilla hamwe nigitoki cya shokora. Nibintu nyamukuru bya acide mubintu bivangavanga, bishobora kubyara gazi gaze karuboni gahoro gahoro, ibibyimba ni bimwe kandi byoroshye, kandi bishobora kubyara udutsima dufite uburyohe budasanzwe.
6. Ibikoresho bya chelating
GDL ikoreshwa nka chelating agent munganda zamata ninganda zinzoga kugirango birinde lactite na tartar.
7. Intungamubiri za poroteyine
Mu mazi arimo poroteyine irimo amazi mabi y’inganda, hiyongereyeho flocculant igizwe n umunyu wa calcium, umunyu wa magnesium na GDL birashobora gutuma poroteyine agglutinate ikagwa, ishobora gukurwaho nuburyo bwumubiri.
Kwirinda
Glucuronolactone ni ifu yera ya kirisiti, ishobora kubikwa igihe kirekire mugihe cyumye, ariko ikabora byoroshye muri acide ahantu h’ubushuhe, cyane cyane mubisubizo byamazi. Ku bushyuhe bwicyumba, lactone mumuti ibora mo acide muminota 30, kandi ubushyuhe buri hejuru ya dogere 65. Umuvuduko wa hydrolysis wihuta, kandi uzahindurwa rwose acide gluconic mugihe ubushyuhe buri hejuru ya dogere 95. Kubwibyo, iyo lactone ikoreshwa nka coagulant, igomba gushonga mumazi akonje hanyuma igakoreshwa mugihe cyisaha. Ntukabike igisubizo cyamazi igihe kinini.
