Colorkem ya ƙaddamar da sabon Ƙarin Abinci: Glucono-delta-lactone a ranar 20th. Yuli, 2022. Glucono-delta-lactone an rage shi azaman lactone ko GDL, kuma tsarin kwayoyinsa shine C6Hl0O6. Gwaje-gwajen toxicological sun tabbatar da cewa abu ne mai guba mara guba. Farin lu'ulu'u ko farin lu'u-lu'u, kusan mara wari, mai daɗi na farko sannan kuma mai ɗanɗano. mai narkewa cikin ruwa. Ana amfani da Glucono-delta-lactone a matsayin mai coagulant, galibi don samar da tofu, da kuma a matsayin furotin coagulant na kayan kiwo.
Ka'ida
Ka'idar glucoronolide coagulation na tofu ita ce lokacin da lactone ya narke a cikin ruwa zuwa gluconic acid, acid yana da tasirin coagulation na acid akan furotin a cikin madarar soya. Saboda bazuwar lactone yana da ɗan jinkirin, halayen coagulation ɗin daidai ne kuma ingancin yana da girma, don haka tofu da aka yi fari ne kuma mai laushi, mai kyau a cikin rabuwar ruwa, jure dafa abinci da soya, mai daɗi da na musamman. Haɗa sauran abubuwan da ake amfani da su kamar: gypsum, brine, calcium chloride, kayan yaji na umami, da sauransu, na iya yin tofu iri-iri.
Amfani
1. Tofu coagulant
Yin amfani da glucono-delta-lactone a matsayin furotin coagulant don samar da tofu, rubutun yana da fari da taushi, ba tare da haushi da astringency na brine na gargajiya ko gypsum ba, babu asarar furotin, yawan amfanin tofu mai girma, da sauƙin amfani.
Ganin cewa idan aka yi amfani da GDL kadai, tofu yana da ɗanɗano mai ɗanɗano kaɗan, kuma ɗanɗanon ɗanɗano bai dace da tofu ba, don haka ana amfani da GDL da CaSO4 ko wasu coagulant a hade wajen samar da tofu. A cewar rahotanni, lokacin samar da tofu mai tsabta (watau tofu mai laushi), rabon GDL / CaSO4 ya kamata ya zama 1 / 3-2 / 3, adadin adadin ya kamata ya zama 2.5% na nauyin busassun wake, zafin jiki ya kamata a sarrafa shi a 4 ° C, kuma yawan amfanin tofu ya kamata ya bushe. Sau 5 na nauyin wake, kuma ingancin yana da kyau. Koyaya, akwai wasu matsalolin da yakamata a lura dasu yayin amfani da GDL don yin tofu. Misali, taurin tofu da aka yi daga GDL bai kai na tofu na gargajiya ba. Bugu da ƙari, adadin ruwan wanka ya ragu, kuma furotin da ke cikin ɗigon wake ya ɓace fiye da haka.
2. Madara gelling wakili
GDL ba wai kawai ana amfani dashi azaman furotin coagulant don samar da tofu ba, har ma azaman furotin coagulant don samar da furotin madara na yogurt da cuku. Nazarin ya nuna cewa ƙarfin gel ɗin madarar saniya da aka samar ta hanyar acidification tare da GDL shine sau 2 na nau'in fermentation, yayin da ƙarfin gel ɗin yogurt akuya wanda acidification tare da GDL ya ninka sau 8-10 na nau'in fermentation. Sun yi imani da cewa dalilin rashin ƙarfi gel ƙarfi na fermented yogurt na iya zama tsoma baki na Starter abubuwa (biomass da salon salula polysaccharides) a kan gel hulda tsakanin sunadarai a lokacin fermentation. Wasu nazarin sun kuma nuna cewa gel ɗin madara da aka samar ta hanyar acidification na ƙari 3% GDL a 30 ° C yana da irin wannan tsari ga gel ɗin da kwayoyin lactic acid ke samarwa. An kuma bayar da rahoton cewa ƙara 0.025% -1.5% GDL zuwa madarar buffalo zai iya cimma daidaitattun pH da ake bukata, kuma takamaiman ƙari ya bambanta da kitsen madarar buffalo da zafin jiki na kauri.
3. Ingantaccen inganci
Yin amfani da GDL a cikin naman abincin rana da naman alade na gwangwani na iya kara yawan tasirin mai canza launi, ta haka ne rage yawan nitrite, wanda ya fi guba. Don ingancin abincin gwangwani, matsakaicin adadin ƙari a wannan lokacin shine 0.3%. An ba da rahoton cewa ƙara GDL a 4 ° C zai iya inganta elasticity na fibrillin, da kuma ƙara GDL zai iya ƙara yawan elasticity na gel, ko a gaban myosin da myosin ko a gaban myosin kadai. ƙarfi. Bugu da kari, hada GDL (0.01% -0.3%), ascorbic acid (15-70ppm) da sucrose fatty acid ester (0.1% -1.0%) a cikin kullu na iya inganta ingancin burodi. Ƙara GDL zuwa soyayyen abinci na iya ajiye mai.
4. Abubuwan kariya
Binciken Saniea, Marie-Helence et al. ya nuna cewa GDL na iya shakkar jinkirtawa da hana phage samar da kwayoyin lactic acid, don haka tabbatar da ci gaba na al'ada da haifuwa na kwayoyin lactic acid. Ƙara adadin da ya dace na GDL zuwa madara yana hana rashin kwanciyar hankali da ke haifar da phage a ingancin samfurin cuku. Qvist, Sven et al. yayi nazarin abubuwan adanawa na GDL a cikin babban tsiran alade ja, kuma ya gano cewa ƙara 2% lactic acid da 0.25% GDL zuwa samfurin na iya hana haɓakar Listeria yadda ya kamata. An adana manyan samfuran tsiran alade ja da aka yi wa Listeria a zazzabi na 10 ° C na kwanaki 35 ba tare da haɓakar ƙwayoyin cuta ba. Samfurori ba tare da masu kiyayewa ba ko kawai sodium lactate an adana su a 10 ° C kuma kwayoyin za su yi girma da sauri. Koyaya, yana da kyau a lura cewa lokacin da adadin GDL ya yi yawa, mutane na iya gano warin da ke haifar da shi. An kuma bayar da rahoton cewa yin amfani da GDL da sodium acetate a cikin wani rabo na 0.7-1.5: 1 na iya tsawanta rayuwar shiryayye da sabo na burodi.
5. Acidifiers
A matsayin acidulant, GDL za a iya ƙara zuwa zaki sherbet da jelly kamar vanilla tsantsa da cakulan ayaba. Shi ne babban abu na acidic a cikin fili yisti wakili, wanda zai iya sannu a hankali samar da carbon dioxide gas, kumfa ne uniform da m, kuma zai iya samar da wainar da musamman dandano.
6. Masu zamba
Ana amfani da GDL azaman wakili na chelating a cikin masana'antar kiwo da masana'antar giya don hana samuwar lactite da tartar.
7. Protein flocculants
A cikin ruwan sharar masana'antu mai gina jiki, ƙari na flocculant wanda ya ƙunshi gishiri na calcium, gishiri na magnesium da GDL na iya sa sunadaran agglutinate da hazo, wanda za'a iya cire su ta hanyoyin jiki.
Matakan kariya
Glucuronolactone wani farin lu'ulu'u ne na foda, wanda za'a iya adana shi na dogon lokaci a ƙarƙashin yanayin bushewa, amma yana sauƙi bazuwa zuwa acid a cikin yanayi mai laushi, musamman a cikin maganin ruwa. A cikin zafin jiki, lactone a cikin maganin yana ɓarna a cikin wani ɓangare na acid a cikin minti 30, kuma zafin jiki yana sama da digiri 65. Ana haɓaka saurin hydrolysis, kuma za a canza shi gaba ɗaya zuwa gluconic acid lokacin da zafin jiki ya wuce digiri 95. Don haka, idan ana amfani da lactone a matsayin coagulant, ya kamata a narkar da shi a cikin ruwan sanyi kuma a yi amfani da shi a cikin rabin sa'a. Kada a adana maganin sa na ruwa na dogon lokaci.
