      Abstract
      Wedang tahu merupakan pangan tradisional berbahan baku tahu sutra dan kuah jahe. Penelitian ini bertujuan untuk menentukan konsentrasi kasium sulfat (CaSO4) sebagai koagulan dalam pembuatan serbuk wedang tahu menyusun Informasi Nilai Gizi (ING) serbuk wedang tahu, dan menentukan umur simpan serbuk wedang tahu dengan metode kadar air kritis. Penentuan konsentrasi CaSO4 terpilih dilakukan dengan uji beda dari kontrol. Hasilnya menunjukkan bahwa serbuk wedang tahu berbeda signifikan terhadap wedang tahu tradisional. Dari tiga konsentrasi CaSO4 yang diujikan (3%, 5%, 7%), maka dipilih CaSO4 3% sebagai koagulan serbuk wedang tahu yang memiliki skor beda dari kontrol (wedang tahu tradisional) paling kecil dibandingkan yang lainnya. Satu sajian serbuk wedang tahu mengandung energi total (125 kkal), protein (12% AKG), lemak total (3% AKG), dan karbohidrat (6% AKG). Umur simpan serbuk wedang tahu adalah 1 tahun 6 bulan bila disimpan pada kondisi kelembaban relatif (RH) 78% dan suhu 30 o C dalam kemasan aluminium foil.
       
      Silk tofu dessert, a traditional delicacy made from silk tofu and ginger syrup. This study aimed to determine the concentration of calcium sulfate (CaSO4) as a coagulant in the production of powdered silk tofu dessert, develop the nutrition fact of the product, and determine its shelf life using the critical moisture method. The concentration of CaSO4 was determined through a test different from the control. The results revealed significant differences between the powdered silk tofu dessert and the traditional version. Among the three CaSO4 concentrations examined (3%, 5%, 7%), 3% CaSO4 was selected as the coagulant for the powdered silk tofu dessert, as it received the smallest different from control (traditional silk tofu dessert) score compared to the others. A single serving of the powdered silk tofu dessert provided 125 kcal, 15% of the recommended daily allowance (RDA) of protein, 3% of the RDA for total fat, and 5% of the RDA for carbohydrates. When stored in aluminum foil packaging at 78% relative humidity and 30o C, the shelf life of the powdered silk tofu dessert is determined to be one year and six months.
