Abstract

Diabetic neuropathy is a severe complication of diabetes mellitus, and conventional synthetic drugs used for its management are often associated with undesirable side effects. This study evaluated the potential of Mentawai taro (Colocasia esculenta var. Mentawai) corm as a functional food for the management of diabetic neuropathy. Adult male mice were divided into five groups: a control group (healthy mice fed a standard diet), a diabetic group (alloxan-induced diabetic mice fed a standard diet), and three diabetic groups fed diets supplemented with 15% Mentawai taro corm whole flour, fiber, or starch. After 28 days of dietary intervention, blood glucose levels, sensory and motor functions, malondialdehyde (MDA) levels, and cerebellar histopathology were evaluated. The results showed that Mentawai taro corm fiber significantly reduced blood glucose levels (59.5% reduction), accompanied by a positive trend toward improved sensory responses (25% increase) and a marked enhancement of motor function (41.6% increase) in diabetic mice. Additionally, fiber supplementation reduced MDA levels in brain tissue (19.3% reduction) and attenuated Purkinje cell degeneration in the cerebellum (27.3% reduction). In contrast, Mentawai taro corm whole flour and starch exerted minimal protective effects, with starch supplementation improving motor function only. Overall, among the various Mentawai taro corm preparations tested, the fiber extract was the most effective in ameliorating symptoms of diabetic neuropathy.

Abstract

Organic waste comprises a considerable portion of global waste, requiring effective management. The ability of the black soldier fly (Hermetia illucens, BSF) to convert organic waste into biomass has been well reported. However, bioconversion can be hindered by fiber-rich substrates, a challenge that can be addressed through substrate pretreatment. This study examined the oviposition preferences and larval performance of BSFs in several fruit wastes fermented by effective microorganisms (EMs), which were compared to non-fermented substrates. The oviposition attractants utilized pineapple peel and overripe soursop, with larval performance evaluated among different treatments, i.e., non-fermented pineapple peel (NFP), fermented pineapple peel (FP), non-fermented pineapple peel plus coconut endosperm waste (NFPC), and fermented pineapple peel plus coconut endosperm waste (FPC). Measured parameters included larval biomass, substrate consumption, the waste reduction index (WRI), and adult emergence. The result indicated that fermented pineapple peel produced the highest number of eggs among the oviposition attractant treatments. Larval biomass was highest in FP, while substrate consumption, WRI, and adult emergence rates were comparable between FP and FPC. Overall, the fermented substrates outperformed the non-fermented substrates across all parameters. These findings confirmed that fermentation with EMs enhances the utilization of fruit waste as an oviposition attractant and improves the performance of BSF bioconversion.
