Abstract

Roti mocaf merupakan  produk roti yang menggunakan  mocaf (modified cassava flour) sebagai substitusi  tepung terigu. Penggunaan mocaf  dimaksudkan sebagai salah satu diversifikasi pangan. Salah satu tahapan penting pada pembuatan roti ini adalah proofing. Proofing merupakan waktu istirahat yang diperlukan adonan untuk mengembang, yang dapat dilakukan dengan cara menutup dengan plastik atau dengan memberikan uap air dalam alat rak pengistirahatan. Penelitian pendahuluan telah dilakukan terhadap lama waktu proofing (10, 15  dan 20 menit) yang diperlukan hingga roti dapat mengembang sempurna. Dari penelitian pendahuluan didapatkan bahwa  proofing optimum dilakukan  selama 20 menit. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktorial, Faktor pertama penggunaan tepung mocaf sebesar 10 ; 20  dan 30 % , faktor  kedua adalah perlakuan  proofing, yaitu  menggunakan uap air  dan  menggunakan plastik.  Roti mocaf yang dihasilkan dilakukan pengujian terhadap warna, rasa,tektur dan kesukaan secara keseluruhan roti  baik menggunakan panelis maupun menggunakan alat. Data yang didapat dianalisis menggunakan Anova dengan taraf perbedaan 5%. Apabila di antara perlakuan berbeda nyata maka pengujian dilanjutkan dengan menggunakan Duncan Multiple Range Test  (DMRT).Hasil penelitian menunjukkan bahwa   perlakuan proofing dengan cara uap air  dan cara ditutup plastik  pada pembuatan roti mocaf tidak berbeda nyata pada rasa, tekstur, warna dan kesukaan secara keseluruhan baik secara uji inderawi maupun dengan menggunakan alat.Kata Kunci :  Roti mocaf ; proofing ;  cara uap air ABSTRACT Mocaf bread is a bread product that uses mocaf as a substitute for wheat flour. The use of mocaf is intended as one of food diversification. One of the important steps in making bread is proofing. Proofing is the time needed for the mixture to expand, which can be done by covering with plastic or by providing water vapor in the resting shelves.Preliminary research has been carried out on the length of proofing time (10, 15 and 20 minute), which was needed until the bread can expand perfectly. From preliminary research it was found that the optimum proofing was carried out for 20 minutes. This research was conducted using a randomized complete design with 2 factors,  first factor was  the  use of  mocaf flour with ratio of 10: 20 and 30 precent, second factor was proofing treatment, that was using water vapor method and using covering plastic method.Mocaf bread produced  was tested for color, taste, texture and overall preference for bread both using panelists and using equipment. Data obtained was analyzed using analysis of variances with significance of 5%. If there is a significance difference then it was analyzed using Duncan Multiple Range Test (DMRT).Results of research showed that proofing treatment by water vapor method and plastic cover did not significantly affect on taste, texture, color and overall preference of mocaf bread, as evaluated by sensory and physical test.   Keywords : Mocaf bread ; proofing ;  steam methode

Abstract

The objective of the present study was to determine the optimum condition of decaffeination process with chitosan in a model system using Response Surface Methodology. A 1000ppm caffeine solution was mixed with chitosan in varried concentrations, temperatures and process times.  After filtration, caffeine in the filtrate was determined. The lower caffeine in the filtrate the more effective the decaffeination process. Result of  the experiment showed that among  chitosan concentrations of  50, 60, 70, 80, 90, and 100 mg per 100 ml caffeine solution, the concentration of 70mg was the most effective. Among temperatures applied of 28, 40, 60, 80, 90, and 100oC, the most effective was of 90oC. And among the process times of 15, 30, 60, and 90 minutes, 15 minutes was the most effective. Result of optimatization using RSM showed that  the optimum condition of decaffeination process were concentration of chitosan of 69,52mg, temperature of 89,71oC, and process time of 14,88 minutes. Under this condition the process diminished 79,56% of caffeine from the model system.

Abstract

Wet cassava starch noodles have been developed in Srihardono Village, Pundong-Bantul District. The disadvantage of this noodle is the short shelf life. The objective of this study was to determine the optimum drying conditions to obtain the best quality of dried cassava noodles. The factors, such as temperature and drying time, and noodle layer were evaluated. Dried cassava noodles contain a combination of traditionally processed cassava starch and manufactured cassava starch. The ratio of traditional starch to manufactured starch was 3:2 (w/w). Drying was conducted using a cabinet drier at various temperatures (70, 80 and 90 °C) for 2 h, 2.5 h, 3 h, 3.5 h and 4 h. Noodle layers were 1, 2, 3 and 4. The observed quality parameters were elongation, water content, cooking loss and water absorption. The obtained data were analyzed using a Response Surface Methodology. The range of optimum drying condition was between 76 and 84 °C and drying time between 3.2 and 3.5 h. Noodles were arranged in 2 layers. Dried cassava noodles had an elongation value of 60 to 70%, water content of 8 to 9%, cooking loss of 10 to 12% and water absorption of 140 to 150%.
