Daging buah nipah mengandung banyak nutrisi dan memiliki peran penting dalam kesehatan tubuh. Penelitian ini bertujuan untuk mengetahui komposisi karbohidrat pada daging buah nipah. Kadar gula pereduksi, pati, amilosa dan amilopektin dianalisis dengan metode spektrofotometri, kadar serat dianalisis dengan metode gravimetri, sedangkan komposisi gula (glukosa, fruktosa, sukrosa, dan maltosa) dianalisis dengan High Performance Liquid Chromatography (HPLC). Hasil penelitian menunjukkan proksimat buah nipah basis kering meliputi kadar abu, protein, lipid dan karbohidrat berturut-turut 4,79%, 6,13%, 1,19% dan 87,87%. Komposisi karbohidrat pada daging buah nipah terdiri atas gula pereduksi, pati, amilosa, amilopektin dan serat dengan kadar berturut-turut 5,42%; 52,35%; 3,45%; 48,89%; dan 12,61%. Komposisi gula buah nipah meliputi glukosa, fruktosa, sukrosa dan maltosa berturut-turut 0,48%; 0,38%; 1,27%; dan < 0,85%. Komposisi karbohidrat pada daging buah nipah berkontribusi terhadap kandungan nutrisinya.

Kata kunci : Daging buah nipah, Nypa fruticans, komposisi karbohidrat, gula pereduksi, pati, serat.

Nypa palm fruit flesh contains numerous nutrients and plays a significant role in supporting human health. This study aims to determine the carbohydrate composition of nypa fruit flesh. The levels of reducing sugars, starch, amylose, and amylopectin were analyzed using spectrophotometric methods, while dietary fiber content was measured using gravimetric methods. Sugar composition (glucose, fructose, sucrose, and maltose) was analyzed using High Performance Liquid Chromatography (HPLC). The results showed that the proximate composition of dried nypa fruit flesh consisted of ash 4.79%, protein 6.13%, lipid 1.19%, and carbohydrates 87.87%. The carbohydrate composition of the fruit pulp included reducing sugars 5.42%, starch 52.35%, amylose 3.45%, amylopectin 48.89%, and fiber 12.61%. The sugar composition included glucose 0.48%, fructose 0.38%, sucrose 1.27%, and maltose
