Kupu Whakataki
Ko te DL-Theanine he waikawa amino taiao i tangohia mai i nga rau tii. He mea whakaputa mai i te mahi catalytic o te waikawa, te enzyme polyphenols ranei, a, he inehanga whatu taiao (L- me D-isomers). Nga ahuatanga o DL-Theanine:
Inemate whatu: DL-Theanine kei roto L- me D-isomers he ranunga achiral.
Wairewa: Ka memeha pai te DL-Theanine ki te wai, ka memeha hoki ki te waiwaro, engari he iti te wairewa.
Pūmautanga: Ko te DL-Theanine he ahua pumau i raro i nga ahuatanga ngoikore, ngoikore ranei te waikawa, engari he ngawari te whakaheke i raro i nga tikanga kawakore.
Antioxidant: Ka taea e DL-Theanine te whakakore i nga rauropi kore utu, he kaha te mahi antioxidant, he pai te painga ki te whakaroa i te koroheketanga me te aukati i te ahotea oxidative.
Nutraceuticals: Ka taea te whakamahi i te DL-Theanine hei taapiri kai hei awhina i te whakapai ake i te mahi a te punaha mate me te whakatairanga i te hauora.
Ko nga tikanga whakarite o te DL-theanine ko te tikanga waikawa me te tikanga enzymatic. Ko te tikanga waikawa ko te whakapohehe i nga polyphenols tea ki te waikawa theotic me te waikawa amino ma te tauhohe i nga rau tii me nga waikawa, katahi ka whiwhi DL-theanine ma te tangohanga, te whakamaarama me etahi atu waahanga. Ko te tikanga enzymatic ko te whakamahi i nga whākōkī motuhake hei whakakorikori i te tauhohenga ki te whakapohehe i nga polyphenols tea ki roto i nga waikawa amino, katahi ka tango me te pure kia whiwhi DL-theanine.
Mo nga tangata whai mate mate mate, mate motuhake ranei, me whakamahi i raro i te tohutohu a te taote, tohunga ngaio ranei.
