Lenga sawit minangka lenga sayur sing dijupuk saka mesocarp wit sawit, umume saka spesies Elaeis guineensis,[1] lan sithik saka spesies Elaeis oleifera lan Attalea maripa . Minyak sawit alamiah amarga kandungan alpha lan karoten sing dhuwur. Minyak sawit beda karo lenga inti klapa kernel (palm kernel oil) sing digawé saka inti buah sing padha. Lenga sawit uga beda karo klapa klapa sing diasilaké saka inti buah klapa ( Cocos nucifera ). Bentenané ana warna (lenga kernel sawit ora duwé karotenoid dadi ora abang), lan isi lemak jenuh. Minyak sawit ngemot 41% lemak jenuh, 81% lenga kernel sawit, lan lenga klapa 86%.[2]

Lenga sawit, kalebu lenga sing nduwéni lemak jenuh dhuwur. Minyak sawit semi-padhet ing suhu kamar lan duwé sawétara jinis lemak jenuh , asam lauric (0.1%), asam myristic (1%), asam stearic (5%), lan asam palmitic (44%). Minyak sawit uga duwé lemak tak jenuh ing bentuk asam oleic (39%), asam linoleat (10%), lan asam alpha linoleat (0.3%).[3] Kaya kabèh lenga sayur, lenga sawit ora ngemot kolesterol [4] sanajan konsumsi lemak jenuh dikenal dadi paningkatan kolesterol lipoprotein kapadhetan lan lipoprotein kapadhetan dhuwur amarga metabolisme asam lemak ing awak.[5] Minyak sawit uga GMO gratis, amarga ora ana lenga sawit sing diowahi genetik (GMO) sing dikembangaké kanggo ngasilaké lenga sawit.

Lenga sawit minangka bahan masak sing asring dipigunakaké ing negara-negara tropis ing Afrika, Asia Tenggara lan bagean Brasil . Panganggoné ing industri panganan komersial ing wilayah liya didorong biaya produksi sing kurang [6] lan stabilitas oksidatif nalika digunakaké kanggo digoreng.[7][8]

Tanduran sawérnané sawit ngajak para aktivis lingkungan supaya kuwatir amarga karusakan alas sing akéh banget kanggo nindakaké pertanian monokultur sawit. Tanduran palem sawit iki nyebabaké kelangan habitat orangutan ing Indonesia, sing kalebu spesies kaancam.[9] Ing taun 2004, Meja Bunder babagan Kelapa Sawit Sustainable (RSPO) dibentuk kanggo ngatasi masalah kasebut.[10] Malaysia wiwit 1992 wis mbatesi ekspansi ladang sawit ing wilayah kasebut kanthi nindakaké peraturan ing wates tanah minimal negara dadi alas.[11][12]
