dc.description.abstract | Es krim adalah makanan beku semi padat hasil olahan susu yang dibuat dengan melewati berbagai proses, yaitu pasteurisasi, homogenisasi, pematangan es krim, pengadukan untuk membentuk rongga udara pada adonan es krim, serta pembekuan dalam lemari es. Bunga rosella memiliki kandungan antioksidan yang tinggi. Kandungan antosianin pada bunga rosella mencapai 96 mg dan vitamin C mencapai 280 mg setiap 100 g. Antosianin pada bunga rosella mampu memberikan efek perlindungan terhadap penyakit kardiovaskuler, termasuk penyakit hipertensi. Penelitian ini bertujuan untuk menganalisis sifat fisikokimia, organoleptik dan aktivitas antioksidan es krim yang diberi penambahan bubuk bunga rosella. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan persentase penambahan bubuk bunga rosella berbeda beda yaitu 0%, 5%, 10% dan 15%. Hasil penelitian menunjukkan bahwa penambahan bubuk bunga rosella pada es krim berpengaruh nyata (P<0.05) terhadap nilai pH, kadar air, aktivitas antioksidan, kapasitas antioksidan, daya leleh dan karakteristik organoleptik. Penambahan bunga rosella tidak berpengaruh nyata (P>0.05) pada nilai aw dan overrun. Persentase terbaik ditemukan pada penambahan rosella perlakuan 5%. | id |
dc.description.abstract | Ice cream is a semi-solid frozen food processed by milk which is made by going through various processes, namely pasteurization, homogenization, ripening of ice cream, stirring to form air cavities in the ice cream dough, and freezing in the refrigerator. Rosella flowers have high nutritional content and antioxidant compounds. The anthocyanin content in rosella flowers reaches 96 mg and vitamin C reaches 280 mg for every 100 g. Anthocyanins in rosella flowers are able to provide a protective effect against cardiovascular disease, including hypertension. This study aims to analyze the physicochemical, organoleptic and antioxidant activity of ice cream which was added with rosella flower. This study used a completely randomized design (CRD) with different percentages, namely 0%, 5%, 10% and 15%. The results showed that the addition of rosella flowers to ice cream had a significant effect (P<0.05) on the pH value, water content, antioxidant activity, antioxidant capacity, melting power and organoleptic characteristics. The addition of rosella flowers had no significant effect (P>0.05) on the aw and overrun values. The best percentage was found in the addition of 5% rosella treatment. | id |
