Valorization of non-edible fruit seeds into valuable products: A sustainable approach towards circular bioeconomy

Global imperatives have recently shown a paradigm shift in the prevailing resource utilization model from a linear approach to a circular bioeconomy. The primary goal of the circular bioeconomy model is to minimize waste by effective re-usage of organic waste and efficient nutrient recycling. In essence, circular bioeconomy integrates the fundamental concept of circular economy, which strives to offer sustainable goods and services by leveraging biological resources and processes. Notably, the circular bioeconomy differs from conventional waste recycling by prioritizing the safeguarding and restoration of production ecosystems, focusing on harnessing renewable biological resources and their associated waste streams to produce value-added products like food, animal feed, and bioenergy. Amidst these sustainability efforts, fruit seeds are getting considerable attention, which were previously overlooked and commonly discarded but were known to comprise diverse chemicals with significant industrial applications, not limited to cosmetics and pharmaceutical industries. While, polyphenols in these seeds offer extensive health benefits, the inadequate conversion of fruit waste into valuable products poses substantial environmental challenges and resource wastage. This review aims to comprehend the known information about the application of non-edible fruit seeds for synthesising metallic nanoparticles, carbon dots, biochar, biosorbent, and biodiesel. Further, this review sheds light on the potential use of these seeds as functional foods and feed ingredients; it also comprehends the safety aspects associated with their utilization. Overall, this review aims to provide a roadmap for harnessing the potential of non-edible fruit seeds by adhering to the principles of a sustainable circular bioeconomy.

Effect of extrusion processing on techno-functional, textural and bioactive properties of whole grain corn flour-based breakfast cereals sweetened with honey

The present study investigated the effect of honey and extrusion processing parameters on techno-functional and bioactive properties of wholegrain corn flour breakfast cereals. The central composite rotatable design (CCRD) was used to plan the experiments using feed moisture (FM), extrusion temperature (ET), and honey level as process variables and sectional expansion ratio (SER), bulk density (BD), water absorption index (WAI), water solubility index (WSI), and textural hardness as response variables. The feed containing honey and wholegrain corn flour was extruded through a twin-screw extruder according to CCRD. The data were fit in the appropriate regression models based on model significance and insignificant lack-of-fit. The selected experiments from CCRD were considered for studying the bioactive properties and the effect of ET and honey level on bioactive properties was determined. The results of the study indicated that FM and honey adversely affected the SER, BD, and textural hardness while ET augmented these properties of breakfast cereals. The WAI decreased with an increase in honey level and ET during extrusion. The incremental addition of honey in the mix as well extrusion at elevated temperature led to higher WSI. The whole grain corn flour added with 10.22% honey and extruded at 16.06% FM, and 138.07 ^o C ET produced optimum quality breakfast cereals with 0.70 desirability. The total phenolic content of breakfast cereals decreased and antioxidant activity, and hydroxymethylfurfural content increased upon extrusion at the higher temperatures. Honey addition lowers the loss of phenolic content during extrusion and improved the antioxidant activity of breakfast cereals. This article is protected by copyright. All rights reserved.
