Pengaruh pemberian pati tapioka termodifikasi polifenol teh hijau dan daun jambu biji merah pada tikus normal dan diabetes

Abstract

The aim of this research was to develop low digestibility starch made from tapioca (Manihot utilisima) modified with polyphenol extracts of green tea and guava leaves which are useful for reducing the risk of diabetes mellitus. Ration containing of tapioca starch modified with 4% green tea and 4% guava leaf extracts were fed to streptozotocin induced diabetic Sprague dawley rats. After 35 days of experiment, the blood glucose level, blood lipid profile, liver antioxidant activity and pancreatic Langerhans islets were assayed. The result showed that the tapioca starch modified with 4% green tea and 4% guava leaf extract diets could lower blood sugar levels in diabetic rats and increase the population of beta cells of pancreatic islets. The rations did not influence the serum lipid profile and liver antioxidant activity of the rats.
