2015 ayaa lagu calaamadeeyay Kanada. Si aad ah ayaa loo filayaa waddan soo saaray 2014 litir oo sharoobada maple ah 38 oo keliya. Sida wax soo saarka ugu weyn adduunka, Kanada dhab ahaantii ma siin dareenka ku filan cilmi-baarista sayniska ee caanka ah ee macaan ee ku salaysan dhirta.
Isku daygii ugu dambeeyay ee cilmi-baarista ayaa ka yimid Jasiiradda Rhode, oo ah gobol aad uga fog soo saarista sharoobada maple. 2013-2014, cilmi-baarayaal ka tirsan Jaamacadda Rhode Island waxay ogaadeen in xeryahooda phenolic ee ku jira maple ay si guul leh u yareeyeen korriinka unugyada kansarka ee koray. Intaa waxaa dheer, soosaarka kakan ee xeryahooda phenolic ee sharoobada maple ayaa saameyn anti-bararka ku leh unugyada.
Sharoobada Maple waxay qani ku tahay xeryahooda falceliska ah oo ay cilmi-baarayaashu sheegeen inay hayaan ballanqaad macquul ah oo ku saabsan guryaha dawooyinka.
Daraasad lagu sameeyay jaamacadda Toronto ayaa lagu ogaaday in . Saynisyahanada jaamacadda McGill waxay ogaadeen in laga soosaaray sharoobada maple ay ka dhigayso bakteeriyada cudur-sidaha inay u nuglaato antibiyootiga, taas oo yaraynaysa awooda ay u leeyihiin inay sameeyaan "bulsho" deggan.
Waxaa jiray dhowr daraasadood oo dheeraad ah oo ku saabsan sifooyinka anti-bararka ee xeryahooda phenolic iyo sida casiirka maple uu dib ugu soo celiyay microflora mindhicirka ee jiirarka heerarka caadiga ah ka dib markii la isticmaalo antibiyootiga.
Dr. Natalie Tufenkji oo ka socota Jaamacadda McGill ayaa la wadaagaysa sheekadeeda ku saabsan sida ay ku bilowday cilmi baarista sharoobada maple. Sida laga soo xigtay iyada, waxay ku dhacday "waqtiga saxda ah, meesha saxda ah: Dr. Tufenkzhi ayaa wax ka qabatay sifooyinka bakteeriyada ee soosaarida karamberriga. Mid ka mid ah shirarka mawduuca ku saabsan, qof ayaa sheegay faa'iidooyinka caafimaad ee suurtogalka ah ee sharoobada maple. Waxay lahayd hab lagu soo saaro waxyaabaha laga soosaaray oo lagu tijaabiyo saamaynta bakteeriyada cudur-sidaha. Dukaan weyn oo xaafadda ah, dhakhtarku wuxuu soo iibiyay sharoobada wuxuuna go'aansaday inuu tijaabiyo.
Aaggan cilmi-baarista sayniska ayaa ah mid cusub oo Kanada ah, oo ka duwan Japan, taas oo muujinaysa natiijooyin aad u wanaagsan aaggan. Dhacdo ahaan, Japan weli waa hogaamiyaha adduunka ee cilmi-baarista shaaha cagaaran.
