Special Issue Information

Dear Colleagues,

The global food industry is undergoing a critical transition as it responds to increasing demands for sustainability, efficient resource utilization, and environmental protection. Climate change, population growth, and food system inefficiencies necessitate the adoption of innovative technologies that enhance productivity while minimizing environmental impact. In this context, rapid advances in food science, processing technologies, and digitalization are creating new opportunities for more sustainable and resilient food production systems.

This Special Issue, “Advances in Sustainable Food Technology and Food Industry”, aims to showcase cutting-edge research, emerging technologies, and applied strategies that support circular economy principles and contribute to reducing the environmental footprint of food systems. Topics of interest include, but are not limited to, the valorization of agro-industrial by-products, the development of green and energy-efficient processing methods, the application of novel preservation and non-thermal technologies, and the integration of smart, data-driven solutions for sustainable production and supply chain management. By bringing together interdisciplinary academic research and industrial perspectives, this Special Issue seeks to promote innovation, enhance knowledge transfer, and support the transition toward a more sustainable, resilient, and resource-efficient food industry

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Craft breweries generate a complex set of byproducts that exceed 2 million tons annually. Their disposal possesses material handling, financial, and environmental challenges. A mixture of these, namely trub, hops, and yeast, designated THYM®, was evaluated biochemically and in a feeding trial to enhance its valuation. THYM contained approximately 3% α plus β hop acids, 0.2% xanthohumol (XN), and 35% crude protein. It exhibited antimicrobial activity, with a minimum inhibitory concentration of 137 ± 39 μg/mL for B. subtilis, and antioxidant activity, with 90 ± 13 μmol/g of Trolox equivalents. THYM presented positive results in bovine rumen microbial in vitro fermentations, decreasing methane production and the acetate:propionate ratio at 3 mg/mL. These results led to a nine-week feedlot trial with 45 Black Angus weanling steers on either a corn silage-based diet (CON), CON with monensin (MON) at 200 mg/animal, or CON with 1% THYM (THYM). Data were analyzed by SAS 9.4 with two orthogonal contrasts of CON vs. MON and THYM and MON vs. THYM. While average daily gain (ADG) and dry matter intake (DMI) did not differ among treatments, a tendency was observed for the THYM and MON groups to have a greater gain to feed ratio (ADG:DMI) when compared to CON (p = 0.07). The XN metabolite 8-prenylnarigenin, a potent phytoestrogen, was present in the serum of the THYM group at 4.0 ± 0.9 nM by mass spectrometry. These brewing byproducts, which can be drum-dried, were well tolerated and show potential value as a cattle growth promoter. Full article
