Usoro mmep?ta omenala nke inositol b? nr?gide hydrolysis. N'ihi af? nke ah?mah? mmep?ta mmep?ta ihe, usoro hydrolysis nr?gide b? isi usoro nkà na ?z? nke nd? na-emep?ta ?l? nakweere ma n?gide na-emewanyewanye na mmep?ta. Usoro n'ozuzu nke nr?gide hydrolysis usoro b? d? ka nd? a: phytin (hydrolysis) → hydrolysis ngw?ta (neutralization, filtration) → inositol ngw?ta (mwep? ad?gh? ?cha na itinye uche, crystallization centrifugation) → crude inositol (mkp?sa na ad?gh? ?cha mwep?, crystallization centrifugation) → ezi ngwaah?a. N'ime ha, hydrolysis na refining b? isi nz??kw? ab??.
Sodium phytate hydrolysis
N'iji mmiri am?k?r? ?ka d? ka ak?r?ngwa, sodium phytate na-emep?ta site na ion mgbanwe resin adsorption usoro, wee tinye nr?gide hydrolysis mmeghachi omume iji mep?ta inositol. N'otu oge ah? na-emep?ta inositol, co mmep?ta nke disodium hydrogen phosphate (mmep?ta nke disodium hydrogen phosphate b? ihe d? ka ugboro 12 nke inositol) n'?z? d? irè na-agbake organic phosphorus si ?ka, na-emeghe ?z? ?h?r? maka mgbake nke organic phosphorus na-ar? ?r? ugbo na sideline ngwaah?a.

Usoro catalytic nr?gide ikuku
Usoro catalytic nr?gide ikuku b? usoro ?h?r? maka imep?ta inositol nke emep?tara ?h?r? ma tinye ya na mmep?ta mmep?ta ihe na China n'af? nd? na-ad?begh? anya. Hydrolysis na nn?cha ya nwere njirimara p?r? iche. Njirimara nd? d? mkpa:
