Purple sweet potato (Ipomoea batatas L.) was selected as a raw material for analog rice due to its carbohydrate, dietary fiber, and anthocyanin contents, which had the potential to improve the product’s functional properties. The addition of Glycerol Monostearate (GMS) in the production of analog rice served as an emulsifier to improve the product’s texture and characteristics. This study aimed to determine the effect of GMS concentration on the physical, chemical, and sensory characteristics of analog rice and to identify the optimal GMS concentration that yields the best product quality. The study was designed using a Randomized Completely Block Design (RCBD) with a single factor and 8 levels of GMS concentration treatment, namely 0%; 0.5%; 1%; 1.5%; 2%; 2.5%; 3%; 3.5%; with 3 replicates. The data were analyzed using ANOVA and further tested using the Honest Significant Difference (HSD) test at the 5% significance level. The results showed that the addition of GMS had a significant effect on yield, density, water absorption, rehydration time, moisture content, texture, and overall acceptance of the analog rice. The addition of 2.5% GMS was selected as the best treatment, yielding a yield of 47.98%, density of 1.07 g/mL, water absorption of 84.13%, rehydration time of 6.21 minutes, expansion capacity of 11.92%, moisture content of 8.80%, and ash content of 2.32%. This treatment also yielded good panelist acceptability scores for texture, color, aroma, taste, and overall acceptability. Based on the research results, purple sweet potato-based analog rice with optimal GMS addition has the potential to be developed as an alternative food product with favorable characteristics. Key words: Analog rice, glycerol monostearate, purple sweet potato Ubi jalar ungu (Ipomoea batatas L.) dipilih sebagai bahan baku beras analog karena mengandung karbohidrat, serat pangan, dan antosianin yang berpotensi meningkatkan nilai fungsional produk. Penambahan Gliserol Monostearat (GMS) pada pembuatan beras analog berfungsi sebagai emulsifier untuk memperbaiki tekstur dan karakteristik produk. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi GMS terhadap karakteristik fisik, kimia, dan sensori beras analog serta menentukan konsentrasi GMS terbaik yang menghasilkan mutu produk optimal. Penelitian disusun menggunakan Rancangan Acak Kelompok Lengkap (RAKL) faktor tunggal dengan 8 taraf perlakuan konsentrasi GMS, yaitu 0%; 0,5%; 1%; 1,5%; 2%; 2,5%; 3%; 3,5%; dengan 3 kali ulangan. Data dianalisis menggunakan ANOVA dan uji lanjut BNJ taraf 5%. Hasil penelitian menunjukkan bahwa penambahan GMS berpengaruh nyata terhadap rendemen, densitas, daya serap air, waktu rehidrasi, kadar air, tekstur, dan penerimaan keseluruhan beras analog. Penambahan GMS 2,5% dipilih sebagai perlakuan terbaik dengan rendemen 47,98%, densitas 1,07 g/mL, daya serap air 84,13%, waktu rehidrasi 6,21 menit, daya mengembang 11,92%, kadar air 8,80%, dan kadar abu 2,32%. Perlakuan tersebut juga menghasilkan tingkat kesukaan panelis yang baik pada parameter tekstur, warna, aroma, rasa, dan penerimaan keseluruhan. Berdasarkan hasil penelitian, beras analog berbasis ubi jalar ungu dengan penambahan GMS optimal berpotensi dikembangkan sebagai produk pangan alternatif dengan karakteristik yang baik. Kata kunci: beras analog, gliserol monostearat, ubi jalar ungu
