Optimization of formulation of Tortilla containing Whey Powder and Soy Flour using Mixture Design-Extreme vertices

Teh dan rempah memiliki kandungan antioksidan yang berguna untuk kesehatan. Tujuan dari pembelajaran ini adalah untuk mendapatkan formula minuman fungsional teh dan rempah terbaik. Penelitian ini menggunakan mixture design untuk menentukan formula optimum minuman fungsional terbaik yang terdiri dari gula merah, bubuk kayu manis dan bubuk kapulaga. Berdasarkan input batas atas dan batas bawah dari bahan baku sehingga didapatkan 16 formulasi yang akan diteliti. Untuk batas atas gula merah yaitu 40 dan batas bawah gula merah yaitu 35. Untuk batas atas bubuk kayu manis yaitu 15 dan batas bawah kayu manis yaitu 10. Untuk batas atas bubuk kapulaga yaitu 50 dan batas bawah bubuk kapulaga yaitu 45. Untuk menentukan kualitas minuman fungsional dilakukan uji kimia (uji karbohidrat, gula total dan nilai pH, uji fisik (Uji viskositas), uji organoleptik (uji hedonik untuk warna, aroma, rasa dan kekentalan) dan mutu hedonik yang ditentukan dari kesukaan panelis terhadap warna, aroma, rasa dan kekentalan) dan uji antioksidan. Penelitian ini untuk mendapatkan formula optimum yang terbaik dari hasil pengacakan oleh mixture design. Hasil dari pengolahan mixture design adalah anova, grafik dan duncan. Berdasarkan hasil penelitian formula minuman fungsional yang masih dapat diterima adalah formulasi 11 yang terdiri dari 40% gula merah, 12.67% bubuk kayu manis dan 47.32% bubuk kapulaga. Formula 11 mengandung 0.39% karbohidrat, 15.46% gula total, 5.38% pH 4.98% viskositas dan 255.41 mg antoksidanSpice tea have antioxidants compounds that are beneficial for health. The purpose of this study was to get the best spice tea formulation as a functional drink. This research used a mixture design to obtain the best optimum formula functional drink that composed by brown sugar, cinnamon powder and cardamom powder. Based on input the upper and lower limits of raw materials then get 16 formulations will be researched. The upper limit of brown sugar, cinnamon powder and cardamom powder is 40, 15 and 50. The lower limit of brown sugar, cinnamon powder and cardamom powder is 35, 10 and 45. The functional drink quality determined by chemical test (carbohydrate level, total sugar and pH value), physical test (viscosity level), organoleptic test and antioxidan level. Data was processed statistically using Design Expert application with one-way analysis (one way ANOVA) at 95% confidence level. Duncan`s follow-up was carried out to find out the differences between treatments if ANOVA had a significant effect. Based on the results of the research, formulation functional drink are still aceptable is formulation 11 of 40% brown sugar, 12.67% cinnamon powder and 47.32% cardamom powder. Formulation 11 contained carbohydrate level 0.39%, total sugar 15.46% and pH value 5.38%, viscosity level 4.98%, and antioxidan level 255.41 mg

Background: Mesalazine (5-aminosalicylic acid, 5-ASA) is a drug substance with an antiinflammatory activity, which is mainly used in the symptomatic treatment of diseases, such as Ulcerative Colitis, the Crohn's disease and the idiopathic inflammatory bowel disease. Mesalazine exerts its effect locally in the inflamed area of the intestine and not through systematic absorption, therefore the investigation of its release characteristics from solid pharmaceutical formulations is of great importance. Objective: The development of novel mesalazine modified release formulations with improved properties, regarding drug release in the gastrointestinal tract, by utilisation of the Design of Experiments (DoE) approach. Methods: D-optimal experimental design was applied. A Simplex Lattice mixture design was used for the development of suitable capsules containing 4 mini tablets and a D-optimal mixture design was used for compression-coated tablets, with the following characteristics: ≤10% release in 2 h, to minimize its degradation in the upper gastrointestinal tract, 20-40% release in 5 h for mesalazine administration in the small intestine, and quantitative release in 12 h for colonic delivery. The dissolution experiments were conducted in gastrointestinal-like fluids and pectinases to simulate the pectinolytic enzymes present in the colon. Results: The optimal compositions were reached via the desirability function, as a compromise to the different responses. The optimal solutions for both formulations led to colon-specific delivery of the active substance with minimal 5-ASA release in the upper gastrointestinal tract and appeared to conform with the pre-determined characteristics. Hard gelatin capsules, when filled with mini-tablets led to the aimed modified release profile, having sigmoidal characteristics and compression coated tablets led to colonic delivery. Conclusion: Two novel mesalazine formulations were developed with the desirable colonic release, by conducting a minimal number of experiments, as suggested by DoE experimental design.
