Gịnị bụ mmetụta nke organic acids na acidified glycerides na "a machibidoro iwu na iguzogide ibelata"?
Ebe ọ bụ na mmachibido iwu ndị Europe na ndị na-akwalite uto ọgwụ nje (AGPs) na 2006, iji organic acids na-eri nri anụmanụ aghọwo ihe dị mkpa na ụlọ ọrụ nri. Mmetụta dị mma ha na-emetụta àgwà nri na arụmọrụ anụmanụ dị kemgbe ọtụtụ iri afọ, ebe ha na-adọtawanye mmasị nke ụlọ ọrụ nri.
Gịnị bụ organic acids?
Organic acids" na-ezo aka na acid niile a na-akpọ carboxylic acid wuru na skeleton carbon nke nwere ike ịgbanwe usoro ọdịdị ahụ nke nje bacteria, na-ebute mmebi nke metabolic na-egbochi mmụba na-eduga na ọnwụ.
Ihe fọrọ nke nta ka ọ bụrụ acid organic niile a na-eji na-eri nri anụmanụ (dị ka formic acid, propionic acid, lactic acid, acetic acid, sorbic acid ma ọ bụ citric acid) nwere usoro aliphatic ma bụrụ isi iyi ike maka mkpụrụ ndụ. Na ntule ndịiche,

Ịdị irè nke organic acid na igbochi uto microbial na-adabere na uru pKa ya, nke na-akọwa pH nke acid na 50% n'ụdị ya na-ekewaghị ekewa. Nke ikpeazụ bụ ụzọ nke organic acids nwere ihe antimicrobial. Ọ bụ naanị mgbe organic acids dị n'ụdị ha na-adịghị ekewa ka ha nwere ike ịgafe mgbidi nke nje bacteria na fungi ma gbanwee metabolism ha ka ha nwere ikike antimicrobial.

Acidified glyceride
N'afọ ndị 1980, ọkà mmụta sayensị America Agre chọpụtara protein akpụkpọ anụ nke a na-akpọ aquaporin. Nchọpụta nke ọwa mmiri na-emepe mpaghara ọhụrụ nke nyocha. Ka ọ dị ugbu a, ndị ọkà mmụta sayensị achọpụtala na aquaporins dị ebe niile na anụmanụ, osisi na microorganisms.
