Gandum kuda atau gandum hitam atau buckwheat (Fagopyrum esculentum) ialah tumbuhan yang ditanam untuk bijirinnya dan juga sebagai tanaman penutup bumi. Untuk membezakannya dari spesis berkaitan, Fagopyrum tataricum yang ditanam sebagai bijian di Pergunungan Himalaya, dan dari spesis yang kurang ditanam Fagopyrum acutatum, ia juga dikenali sebagai gandum kuda Jepun[2] atau gandum kuda silverhull.[2]

Ladang gandum kuda di Bumthang (Bhutan)

Walaupun namanya begitu, gandum kuda ini tiada kaitan dengan gandum kerana ia bukan spesis rumput. Malah, gandum kuda ini mempunyai kaitan dengan sorrel, knotweed, dan rubarb. Disebabkan benihnya dimakan, ia dirujuk sebagai bijirin pseudo.

Penanaman bijian gandum kuda menurun dengan mendadak pada abad ke-20 dengan penggunaan baja nitrogen yang meningkatkan produktiviti tanaman ruji lain.

Komposisi kimia

sunting
 
Gandum kuda masak
Kanji
  • 71–78% dalam bentuk bijirin nyahkulit
  • 70–91% dalam bentuk pelbagai jenis tepung[3][4][5]
  • Kanji sebanyak 25% amilosa dan 75% amilopektin.
  • Bergantung kepada tindak balas hidroterma, gandum kuda nyahbijirin mengandungi 7–37% kanji tahan.
Protein
  • Protein mentah sebanyak 18%, dengan nilai biologi melebihi 90%.[6] Ini boleh diterangkan dengan kepekatan tinggi semua asid amino penting,[7] terutamanya lisina, treonina, triptofan, dan asid amino yang mengandungi sulfur.[8]
Galian
Antioksida dalan bentuk fenolik
Sebatian beraroma

salisilaldehid (2-hidroksibenzaldehid) dikenalpasti sebagai komponen aroma gandum kuda.[13] 2,5-dimetil-4-hidroksi-3(2H)-furanon, (E,E)-2,4-dekadienal, fenilasetaldehid, 2-metoksi-4-vinilfenol, (E)-2-nonenal, dekanal dan heksanal juga menyumbang kepada aroma. Kesemuanya mempunyai nilai aktiviti bau melebihi 50, tetapi aroma bahan ini dalam keadaan terasing dan tidak menyerupai gandum kuda.[14]

Terbitan Inositol

Fagopiritol A1 dan fagopiritol B1 (isomer mono-galaktosil D-kiro-inositol), fagopyritol A2 dan fagopyritol B2 (isomer di-galaktosil D-kiro-inositol), dan fagopyritol B3 (tri-galaktosil D-kiro-inositol)[15]
