Fortification of raw rice and rice flour using Cissus quadrangularis L. (veldt grape) stem powder to overcome osteoporosis and its associated skeletal complication through staple diet.

Abstract

This study aimed to prepare the fortified rice/flour with Cissus quadrangularis (CQ) stem powder to eliminate nutritional deficiency and improve bone health. Mineral analysis by atomic absorption spectroscopy revealed that the CQ stem has adequate quantities of calcium, magnesium, and a moderate amount of phosphorous to meet the Recommended Dietary Allowance (RDA). Thus, the rice and flour were fortified with freeze-dried CQ stem powder to improve its nutraceutical contents. The fortification was done using standard vacuum impregnation and blending process. Furthermore, the recuperative activity of prepared fortified rice (CQFR) and flour (CQFF) was tested in chemically induced osteoporosis and osteoarthritis animal models. The efficiency of CQ fortified diet against these complications was confirmed by hematology, radiology, and histopathological analysis. The rat groups fed with CQFF/CQFR diet showed significant improvement from calcium deficiency and its allied physiological damage. Thus, this study confirms that the CQ fortified rice would provide recovery from skeletal complications associated with calcium deficiency through fixing both homeostasis and bio-accessibility of the calcium. PRACTICAL APPLICATIONS: Micronutrient and mineral deficiency is relatively higher in the regions where rice/rice products are consumed as a staple diet. Dietary intake of calcium and some essential minerals have major influences on bone and joint health. Cissus quadrangularis (CQ) is a familiar herb, conventionally used in India to fix broken bones and strengthen the skeletal system. The Atomic absorption spectroscopy data from this study showed that the CQ stem holds a high amount of calcium and other essential minerals to promote skeletal health. Preparation of fortified rice and flour with CQ stem would be a beneficial source of the essential minerals/ bioactive principles to promote and sustain skeletal health in the underprivileged population. These study data substantiated the practical application of producing the CQ fortified nutraceutical staple diet, especially to the people who are afflicted with morbid skeletal complications.
