Niaj hnub no peb yuav tham txog yuav ua li cas raw cov ntaub ntawv cuam tshuam rau particle hardness ntawm particle tshuab. Thaum lub sij hawm sib tsoo, qhov crushing loj ntawm cov khoom siv raw yog qhov txiav txim siab hauv particle hardness. Feem ntau hais lus, qhov zoo dua qhov me me ntawm cov khoom siv raw, qhov yooj yim dua nws yog gelatinize, lub zog adhesion nyob rau hauv cov khoom granular, tsawg fragmentation, thiab ntau dua hardness. Qhov loj me me ntawm kev sib tsoo yog qhov zoo rau qhov loj me thiab qhov zoo li qhov zoo, thiab tuaj yeem ua kom qhov tsim nyog hardness thiab qis crushing tus nqi ntawm cov khoom.
Los ntawm kev kho ua ntej ntawm cov khoom siv raw, nws muaj peev xwm tua tau qee cov kab mob, tshem tawm cov teeb meem tshuaj, denature cov ntaub ntawv raw, thiab tag nrho gelatinize cov hmoov txhuv nplej siab. Gelatinized starch muaj qhov cuam tshuam loj rau particle hardness. Vim tias qib siab ntawm gelatinization thiab hardness ntawm cov ntaub ntawv granular, lwm txoj kev yuav tsum tau siv los txo cov particle hardness. Kev sib xyaw ntawm cov khoom siv raw tuaj yeem txhim kho qhov sib xws ntawm ntau yam khoom me me, pab tswj kev sib xws hauv particle loj hardness, thiab txhim kho cov khoom zoo.
