| Abstract: | Vitamin C bermanfaat untuk meningkatkan imunitas tubuh, tetapi bersifat tidak stabil terhadap suhu. Oleh karena itu, diperlukan metode pengolahan yang mampu mempertahankan kandungan vitamin tersebut dalam produk. Penelitian ini bertujuan untuk mengetahui pengaruh jenis formulasi, metode pengeringan, dan penambahan maltodekstrin terhadap kandungan vitamin C serta kadar air pada sediaan serbuk instan vitamin C. Sampel penelitian terdiri atas jambu biji, pepaya, kiwi, brokoli, dan kembang kol. Analisis kandungan vitamin C dilakukan dengan spektrofotometer UV-Vis, sedangkan kadar air dianalisis menggunakan moisture analyzer. Data kandungan vitamin C dan kadar air diuji dengan ANOVA, DMRT, dan paired sample t-test. Hasil penelitian menunjukkan bahwa komposisi bahan dan perbedaan metode pengeringan berpengaruh terhadap kandungan vitamin C. Selain itu, perbedaan metode pengeringan dan penambahan maltodekstrin berpengaruh terhadap kadar air. Untuk memenuhi 25% Angka Kecukupan Gizi (AKG), diperlukan sediaan serbuk instan vitamin C sebanyak 1,8 g per takaran saji. Vitamin C is beneficial for improving immunity but is unstable at high temperatures. Therefore, a processing method is required to maintain its content in the product. This study aims to determine the effects of formulation type, drying method, and maltodextrin addition on the vitamin C and moisture content of instant vitamin C powder. The research samples consisted of guava, papaya, kiwi, broccoli, and cauliflower. Vitamin C was analyzed using a UV-Vis spectrophotometer, while moisture content was analyzed using a moisture analyzer. Data on vitamin C and moisture content were tested using ANOVA, DMRT, and paired sample t-test. The results showed that ingredient composition and drying method significantly affected vitamin C content. In addition, drying method and maltodextrin addition significantly affected moisture content. To meet 25% of the Recommended Dietary Allowance (RDA), 1,8 g of instant vitamin C powder is required per serving. |
