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]

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

Biji

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

Kaya dalam zat besi (60–100 ppm), zink (20–30 ppm) dan selenium (20–50 ppb)^[9]^[10]

Antioksida dalan bentuk fenolik

10–200 ppm rutin, 0.1–2% tanin^[11] dan kehadiran katekin-7-O-glukosida dalan nyahbijirin.^[12]

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]

Herba

Antioksidan

1–10% rutin dan 1–10% tanin^[16]

Fagopirin

0.4 hingga 0.6 mg/g fagopirin (sekurang-kurangnya 2 bahan serupa)^[17]^[18]

Kegunaannya
