High-sugar mango muchero une mukurumbira unotengeswa kunze kwechando wakaomeswa kubva kuSoutheast-Asia. Zvakadaro, mango pulp ine polyphenol-oxidase yakawanda uye inoderedza-shuga uye inotapukirwa zvakanyanya nekusviba panguva yekugadziriswa. Nzira mbiri huru dzekusviba dziripo: enzymatic browning inoitika kana pulp yakatyoka yasangana neokisijeni uye polyphenol-oxidase inokonzeresa kusviba nekukurumidza; Maillard non-enzymatic browning inoitika pasi pekudziya apo inoderedza-shuga inoita nemaamino-acids uye kusviba pulp. Mafekitari mazhinji anongogadzirisa maparameta ekuomesa chando asi anofuratira nhanho dzepamusoro-soro uye nhanho dzekugadzirira uye zvichiri kutambura nezvinhu zvakakura-kusviba-zvisina kunaka. Yakagadzika kubuda kwegoridhe inopenya-yakaomeswa mango inoda kurongeka izere-cheni yekudzora inovhara mbishi-material giredhi, preteatment color-dziviriro, kuomesa-kuomesa, kuburitsa-kurongedza uye kupedzwa-kuchengetedza zvinhu.
Chekutanga, iri kuuya raw-material grading. Kuibva kwemango kunokanganisa zvakanyanya kuita browning. Mango yakanyanyisa kuibva ine yakapfava pulp ine yakakwirira polyphenol-oxidase chiitiko uye inoenderera yemukati oxidation. Mango ine mavanga akavanzika uye kukuvara-kusvina inotaridzika kunze kunze uku masero emukati atotyoka uye ma enzymes anoburitswa. Kunyangwe iyo yakakwana yekudzika-maitiro haigone kudzivirira zvizere kusviba kune michero yakadaro. Michero mitsva iri kuuya inozoiswa giredhi. Mango yakanyanyoibva uye yakapwanyika inorongwa-kunze. Mango yakaibva zviri pakati nepakati ichakosheswa pakugadzirwa kwemichero yakaomeswa nechando.
Chechipiri, pretreatment color-protection, danho rakanyanya kukosha rekuvharisa enzymatic browning. Mushure mekupepeta nekuchekeresa, nzvimbo huru dzemapulp dzinoburitswa kumhepo uye polyphenol-oxidase inobva yatanga kuita. Usachengeta mango yakachekwa kwenguva yakareba; bvisa-ruvara-kudzivirira kurapwa nekukasira. blanching yenguva pfupi yakakodzera inomisa polyphenol-oxidase uye inodzvanya enzymatic browning. Blanching tembiricha uye nguva inoda kukwenenzverwa zvinoenderana nemhando yemango uye kukora kwechimedu. Kukurumidza kutonhora mushure me blanching kunopedza kupisa mhedzisiro. Nyatsobudisa mvura yepamusoro usati waisa tireyi. Kusakwana enzyme-inactivation inongodzvanyirira enzyme kwenguva pfupi pasi pechando-inoomesa yakaderera-tembiricha nharaunda. Ma Enzymes anowanazve kuita kana tembiricha yakwira muchikamu che sublimation uye browning ichiri kuitika.
Yetatu, kuomesa-kuomesa-chikamu chekudzora kurwisa Maillard browning. Maillard reaction inomhanyisa zvakanyanya nekukwira kwekushisa. Usaseta sherefu-tembiricha yakawandisa muchikamu chepasi kudzivirira kupisa zvakanyanya. Chengetedza vacuum yakagadzikana yekamuri uye kuderedza yemukati-oxygen level kuti inonoke oxidation kumhanya. Kuzadza pre-kuomesa chando kunodiwa kuti pulp yakazara kusimba. Kunyungudika kusati kwakwana kunounza kunyungudika kwenzvimbo. Mavara anonyunguduka anowedzera tembiricha uye nyore kukonzeresa Maillard-kuita uye kusviba kwe pulp. Kupisa amplitude kuchadzorwa zvakare muchikamu chekuomeswa-kuomeswa; tembiricha yakadzika-inokwira inorambidzwa.
Chechina, kuburitsa uye kurongedza. Deredza kuvhurika-wekishopu yekubuda kwemhepo mushure mekuomesa nechando. Mango yakaomeswa nechando ine porous hombe-yepamusoro-nzvimbo uye iri panjodzi yeoxidative discoloration kana ichibata oxygen. Pedzisa vacuum nitrogen-yakazadzwa yekuisa chisimbiso-kurongedza nekukurumidza sezvinobvira mushure mekuburitsa. Gamuchira mabhegi ekurongedza akakwirira-kuvharira kudzivirira kupinda kweokisijeni uye unyoro.
Chechishanu, kupedzwa kwekuchengetedza zvinhu uye zvekufambisa mugungwa. Chengetedza zvinhu zvakaputirwa munzvimbo inotonhorera uye ine rima. Dzivisa kupisa kwenguva refu mukati memidziyo panguva yekutumira kunze kwenyika mugungwa, nekuti kupisa kunowedzera kunonoka kusviba kunokonzerwa nekutsvaga kwasara-oxygen mukati memabhegi akavharwa.
Mukupedzisa: mango browning haigone kugadziriswa nekungoisa chando-dryer paramita. Raw-material grading, pretreatment enzyme-inactivation & color-protection, full-procession-drying tembiricha-control, kukurumidza kubudisa-kurongedza uye kutonhora-tembiricha warehousing akanyatsobatanidzwa anokosha links. Chete yakazara-cheni manejimendi inogonesa kugadzirwa kwakagadzikana kwekunze-giredhi yakaomeswa mango ine chitarisiko chegoridhe chinoyevedza.
