Orange peel flavored unripe plantain noodles with low glycemic index improved antioxidant status and reduced blood glucose levels in diabetic rats

Low glycemic index noodle and pasta: Cereal type, ingredient, and processing

The consumption of noodles with a high glycemic index (GI) can affect health, prompting the need for dietary adjustments to manage abnormal blood glucose levels. This review delves into recent progress in low GI noodles and their potential effect for human well-being. Diverse approaches, encompassing the incorporation of soluble dietary fiber, modified starches, proteins, and plant polyphenols, have shown encouraging outcomes in diminishing the GI of noodles. Furthermore, variations in processing, storage, and cooking techniques can influence the GI of noodles, yielding both positive and negative impacts on their glycemic response. Soluble dietary fiber, protein cross-linkers, and plant polyphenols play a pivotal role in reducing the GI of noodles by hindering the interaction between digestive enzymes and starch, thereby curbing enzymatic activity. Future research spotlighting ingredients, processing methodologies, and the underlying mechanisms of low GI noodles will contribute substantively to the development of functional foods boosting enhanced nutritional profiles.

Functional cereals' anti-diabetic property, phenolic composition, and role on glycemic indices in-vitro

This study analyzed the effects of functional cereals processed and produced from yellow corn, soybean, acha, orange peels and moringa leaves' polyphenolic content, glycemic index, starch composition and their effects on α-amylase and α-glucosidase enzymes in vitro. Functional cereals were produced as ready-to-eat cereals at different proportion with variations in the amount of measured acha flour, soybean flour, and blends of orange peels and moringa leaves while maintaining a constant amount of yellow corn. The produced orange peels and moringa leaves blends inclusion to functional cereals had significantly increased phenolic constituents, showed inhibitory activity on α-amylase and α-glucosidase enzymes in-vitro and reduced glycemic index, starch content and starch to sugar ratios. Interestingly, amongst the produced functional cereals, the best two cereals were with their composition made up of corn, acha, soybean, orange peel, moringa leaves (30: 5:15: 0.5: 0.5) and corn, acha, soybean, moringa leaves (30: 5: 15: 1) which both had the high inhibitory effects on the activities of α-amylase and α-glucosidase while depleting starch content in-vitro when compared with commercially consumed cereals (golden morn). PRACTICAL APPLICATIONS: Ready-to-eat cereals are highly consumed by children and by adults inclusively. Commercial breakfast cereals are readily available and consumed irrespective of the fact it has high calorie constituent as more emphasis is placed on their nutrients value which includes vitamins A, vitamin C and calcium for boosting immune system and for proper body growth and functioning. However, these commercial breakfast cereals (golden morn) owing to the high maize and millet content present in them are unfavorable to certain consumers or individuals with health challenges such as diabetic patients. This study shows that functional cereals produced in-vitro extensively are not only nutritious but also medicinal in nature, offering benefits in the management of diabetes and related complications.
