Abstract

Caulerpa racemosa seaweed is a type of seaweed that can be used as an antidiabetic. Previous studies have shown that Caulerpa. sp. was able to reduce blood glucose levels and showed the regeneration of pancreatic ? cells in diabetic rats. The purpose of this study was to determine the effect of C. racemosa seaweed diet on liver and kidney malondialdehyde levels in diabetic rats. The research stages began with chemical analysis of C. rasemosa seaweed flour and continued with bioassay testing. The analysis included proximate analysis, fiber, total phenol and antioxidant activity of C. rasemosa seaweed, analysis of blood sugar in serum and malondialdehyde (MDA) in the liver and kidneys. Results showed that C. rasemosa seaweed flour contained 11.37% water, 23.24% of ash content, 12.84% of protein, 2.02% of fat, 50.45% of carbohydrate by different, 6.35% of crude fiber, total phenol 2785 mg GAE / g, and 15.68% of antioxidant activity. Diet of C. rasemosa seaweed flour for 30 days was able to reduce blood glucose levels by 53.12% in the diabetic rat group. Liver MDA levels in the group of diabetic rats fed a diet C. rasemosa decreased 17.79% compared to the control group. Renal MDA levels in the diabetic rat group fed a diet of C. rasemosa seaweed were still higher than the control group but 15.53% lower than the diabetic group fed standard diet.

Abstract

Kemajuan industri pangan dipengaruhi oleh banyak faktor salah satu contohnya yaitu nanoteknologi. Penerapan nanoteknologi pada pengolahan pangan memungkinkan untuk menggunakan zat-zat yang memiliki manfaat tambahan yang berguna bagi tubuh manusia. Namun, ada beberapa zat yang kurang efektif jika diaplikasikan secara langsung pada makanan karena berbagai faktor seperti dapat menghasilkan rasa yang tidak dikehendaki dan bioavailabilitas yang rendah. Salah satu zat gizi mikro penting untuk tubuh adalah kalsium, kalsium berperan penting pada kekokohan tulang, pembentuk struktur tulang, transmisi antar sel, pembekuan darah, penyembuhan luka dan masih banyak lagi. Produksi kalsium dengan ukuran nano dapat dilakukan dengan berbagai metode dan sumber kalsium yang beragam. nanokalsium dapat menjadi fortifikan dan dicampurkan langsung ke dalam makanan contohnya seperti susu skim bubuk, cracker, dan bakso. Pemberian nanokalsium meningkatkan densitas mineral pada tulang dan juga dapat meningkatkan volume tulang pada tikus uji. Penambahan nanokalsium pada pangan olahan juga masih bisa diterima oleh konsumen.
