Fragrances　have　been　widely　used　in　many　customer　products　to　improve　the　sensory　quality　and　cover　flavor　defects.　The　key　to　the　successful　application　of　fragrance　is　to　realize　controlled　fragrance　release,　which　relies　on　the　use　of　an　appropriate　carrier　for　fragrance.　An　ideal　fragrance　carrier　helps　to　achieve　the　stable　storage　and　controlled　release　of　fragrance.　In　this　work,　a　novel　composite　fragrance　carrier　with　MIL-101　(Cr)　as　the　fragrance　host　and　cellulose　acetate　fiber　(CAF)　as　the　protective　shell　was　developed.　The　encapsulation　effect　of　MIL-101　(Cr)　and　the　protective　function　of　the　CAF　shell　significantly　improved　the　storage　stability　of　L-menthol　(LM).　Only　5　wt　%　of　LM　was　lost　after　40　days　of　storage　at　room　temperature.　Encapsulated　LM　could　also　be　effectively　released　upon　heating　due　to　the　thermal　responsiveness　of　CAF.　In　addition,　the　composite　carrier　was　highly　stable　with　neglectable　Cr　leaching　under　different　conditions.　The　results　of　this　work　showed　that　the　developed　composite　carrier　could　be　a　promising　carrier　for　the　thermally　triggered　release　of　fragrance.　©　2022　by　the　authors.
