Functionalized pineapple aerogels for ethylene gas adsorption and nickel (II) ion removal applications. Solid-state fermentation for single-cell protein enrichment of guava and cashew by-products and inclusion on cereal bars. There's nothing quite like a fresh, juicy pineapple. But a new process promises to convert the waste into high value aerogels, cheaply and cleanly. Use the link below to share a full-text version of this article with your friends and colleagues. They are effective as oil absorbents and for heat and sound insulation. With these properties, the pot degraded in more than 45 days, N and P release rates … His process uses pineapple leaf fibers to create ultra-light, biodegradable aerogels. The study – published in the journal Food and Bioproducts Processing – reports that waste products from pineapple processing, including the peel and stem of plants, could provide a valuable source of expensive bromelain extract.. Bromelain is an enzyme that is usually extracted from the stems or juice of pineapples. Does white vinegar really neutralize airborne odors and not just mask them? Integral Valorization of Pineapple (Ananas comosus L.) By-Products through a Green Chemistry Approach towards Added Value Ingredients. Current Opinion in Green and Sustainable Chemistry. "Although a complete procedure of waste recycling has not been developed thoroughly, this is an important step towards sustainable development to build creative and innovative thinking of our young generation about helping the environment and preserving nature," he adds.

Though, obtaining these by‐products from such a variable substrate requires an understanding of the composition of the polysaccharides and their associations within the overall substrate. Pineapple waste showed higher concentration of crude fibre, non-reducing sugar, protein, ascorbic acid and moisture content. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Aerogels are among the lightest solid materials known and are created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air. Single cell protein (SCP) is used as a protein supplement in animal feed and protein rich foods for humans. Revalorization of bioactive compounds from tropical fruit by-products and industrial applications by means of sustainable approaches. Their utilisation has become one of the main important and challengeable aspects due to the generation of large quantities of by‐products including peels, seeds, leaves and unused flesh in different steps of processing chain. Apart from any fair dealing for the purpose of private study or research, no through different methods of extractions, purifications and fermentations. Pineapple wastes are normally used as animal feed or disposed in landfills, where the wastes might undergo anaerobic digestion, resulting in methane leakage . By using our site, you acknowledge that you have read and understand our Privacy Policy General uses Few well-controlled clinical trials have been published to support the wide range of therapeutic claims for bromelain, a crude, aqueous extract of pineapple. He has previously developed and patented techniques for creating aerogels from old rubber tires, coffee grounds and plastic bottles. The NUS team is working with partners to pilot the large-scale production of these eco-aerogels for high-value applications such as food preservation, heat insulation, noise reduction, oil-spill cleaning and reusable masks for filtering toxic gases, dust particles and bacteria. part may be reproduced without the written permission.
