Jackfruit (Artocarpus Heterophyllus Lam.) is an underexploited seasonal fruit that is rich in vitamins, minerals, proteins, and carbohydrates. Its commercialization and storage are limited due to its highly perishable nature. At the same time, operations such as peeling, cutting, and coring operations are difficult to perform manually. This review sums up the recent development in the area of novel thermal and nonthermal processing techniques such as retort pouch processing, microwave processing, irradiation, high‐pressure processing (HPP), pulsed electric field technology, ultrasound, supercritical fluid extraction, cold freezing, hurdle technology, and minimal processing were discussed to preserve and processed jackfruit. The impact of different processing techniques on jackfruit's quality, sensory characteristics, and storage period was also demonstrated. Industrial challenges and their prospects are also explicated for entrepreneur beneficiaries. Thermal methods resulted in a more significant loss of nutrients than nonthermal methods. For better results, pooled heat treatment with nonthermal methods is effective. Ultrasonication significantly improved the quality of thermal techniques, micro‐wave treatment, and nonthermal methods. Novelty impact statement Use of novel thermal and nonthermal methods for jackfruit processing is suggested. Combination of mild heat with nonthermal methods was more effective for jackfruit preservation. Microwave and ultrasonication are most effectively analyzed for jackfruit processing. Industrial challenges and their prospects are also explicated for entrepreneur beneficiaries.
India is the largest producer of jackfruit (Artocarpus Heterophyllus Lam.) all over the world. It is an underutilized seasonal fruit rich in vitamins, minerals, proteins, and carbohydrates. A significant chunk of the jackfruit production is wasted due to a lack of postharvest technological interventions. Due to its bulky nature, thickness, and spiky skin, operations like peeling, cutting, and coring are difficult to perform manually.Recently, there is a considerable improvement in the mechanization of jackfruit post-
Plastics are ubiquitous in many sectors including, but not limited to, construction, textiles, electronics and transportation. The immoderate use of single-use plastics has wreaked havoc on society. The intensifying environmental pollution and waste accumulation have driven the scientific communities and industries to shift their focus on biodegradable materials. An ecofriendly and sustainable economic system demands proper usage of raw materials and substitution of fossil fuel-based resources with renewable materials. Of late, bio-based constituents have attracted considerable attention from the public in view of ecological safety and economic interests. Bio-based sources are cost-effective, reusable, sustainable, clean and reduce the ecological footprint. Biopolymers can be derived from biomass (polysaccharides, proteins, lipids), bio-derived substances (polylactate) or from microorganisms (PHB, PHA, Xanthum gum). The commonly used polysaccharides include starch, cellulose, gums and chitosan. However, the hydrophilic nature of most of the polysaccharides affects the physical and mechanical properties and is not on par with the synthetic plastics that are generally used. In order to expand the applications of biodegradable polymers in various sectors, it is imperative to address the challenges associated with gas permeability, processing method, thermal stability etc. Various physical and chemical modification methods are employed to overcome these limitations. Creating awareness among the public and encouraging them to use renewable sources is important. There is a strong need to develop innovative biodegradable products and promote them by fostering collaboration among entrepreneurs, researchers and the government. This paper provides an overview of the biodegradable materials that can be produced from different sources such as vegetable and fruit waste, cereals and pulses waste, seaweeds, animal waste, wood waste, traditional sources and aims to address the current limitations and indicate the future directions.
