Isi mmalite, njirimara na mmebi nke molasses mmanya na-abaghị uru
Mmiri na-ekpofu mmanya Molasses bụ nnukwu uche na mmiri mkpofu ahịhịa dị elu nke a na-ewepụta na ụlọ ọrụ mmanya nke ụlọ ọrụ shuga iji mepụta mmanya na-aba n'anya mgbe agbachara mmiri nke molasses. Ọ bara ụba na protein na ihe ndị ọzọ na-edozi ahụ, ma nweekwa salts inorganic dị ka Ca na Mg na mkpokọta dị elu. SO2 na ndị ọzọ. Dị ka ọ na-adịkarị, pH nke mmiri mkpofu mmanya bụ 4.0-4.8, COD bụ 100,000-130,000 mg/1, BOD bụ 57-67,000 mgSs, 10.8-82.4 mg/1. Na mgbakwunye, ọtụtụ n'ime ụdị mmiri mkpofu a bụ acidic, na agba dị oke elu, agba aja aja-oji, ọkachasị gụnyere agba caramel, agba phenolic, agba Maillard na ihe ndị ọzọ. Ebe ọ bụ na mmiri mmiri na-ekpofu ihe nwere ihe dị ka 10% siri ike, ntinye uche dị ala na enweghị ike iji ya. Ọ bụrụ na a na-agbanye ya ozugbo n'ime osimiri na ala ubi na-enweghị ọgwụgwọ, ọ ga-emerụ àgwà mmiri na gburugburu ebe obibi nke ọma, ma ọ bụ mee ka ala na-eme ka acid na-agbakọta, na-eto eto nke ọrịa ihe ọkụkụ. Otu esi eme ihe na iji mmiri mkpofu mmanya molasses bụ nnukwu nsogbu gburugburu ebe obibi chere ụlọ ọrụ shuga ihu.
