Seaweed has been reported to have a high content of fiber. Seaweed can be processed into many types of more durable products, such as seaweed powder. Seaweed powder could be used as a raw material for making cakes. Mille crepes cake is a classic French cake that consists of several thin layers made from wheat flour. This study developed mille crepes cake from Eucheuma cottonii seaweed powder. This study was a research and development model, focused on the 4D model (Define, Design, Develop, and Disseminate). Wheat flour was substituted with Eucheuma cottonii seaweed powder as much as 2.5%, 5%, and 7%. Based on the five trained panelists’ sensory evaluation, the 5% substitution of seaweed powder resulted in mille crepes cake products with the most acceptable sensory characteristics. Thirty untrained panelists tested the wheat flour control and the 5% seaweed powder product by the hedonic test. The data obtained were analyzed quantitatively. The differences between both samples were measured using paired t-tests. Control products and 5% seaweed powder products did not display any significant difference (p≤0.05) in color, flavor, taste, texture, and overall.
Temperature sangat mempengaruhi kosentrasi molases dalam menghidrolisis tepung jagung. Kenaikan temperature menyebabkan energy kinetic molekul meningkat. Peningkatan energi yang cukup bagi molekul reaktan akan meningkatkan laju reaksi sehingga semakin tinggi temperature konversi yang diperoleh akan semakin tinggipada temperature yang yang tidak melebihi temperature optimum enzim bekerja. Dalam menghidrolisis tepung jagung ke molases dilakukan tiga tahap yakni, gelatinase, likuifikasi, dan sakarifikasi. Metode penelitian yang digunakan yaitu metode eksperimen yang dilakukan di laboratorium. Hasil penelitian ini diperoleh nilai kadar molases, massa molases, dan nilai efisiensi. Pada temperatur (40-45) oC kadar molases yang dihasilkan yakni 8,8 %, massa molases 19,33 gr, efisiensi 64%. Pada temperatur (45-50) oC kadar molases yang dihasilkan yakni 11,6 %, massa molases 25,69 gr, dan efisiensi 86%. Pada temperatur (50-55) oC kadar molases yang dihasilkan meningkat menjadi 13 %, massa molases 26,27 gr, dan efisiensi 88%. Pada temperatur (55-60) oC kadar molases lebih meningkat menjadi 14,6 %, massa molases 28,86 gr dan efisiensi 90%.. Ini artinya semakin tinggi temperatur maka kadar molases juga akan semakin bertambah. Pada temperatur rentang (40-45) oC hanya sebagian kecil molekul yang memiliki energi aktivasi yang cukup untuk bertumbukan menghasilkan reaksi, sehingga tepung jagung yang berhasil terhidrolisis lebih sedikit, sebaliknya pada temperatur (55-60) oC energi kinetik molekul naik sehingga menyebabkan peningkatan laju reaksi. Pada temperatur tersebut adalah temperatur optimum enzim gluko amilase bekerja. Hal ini bersesuaian dengan distribusi Maxwell-Boltzmann yang menyatakan bahwa reaksi akan semakin cepat dengan adanya pertambahan temperatur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
