Special Issue Information

Dear Colleagues,

The disposal of waste and the underutilisation of by-products in the food industry represent major global challenges. Transforming these materials into safe and valuable food ingredients can enhance resource efficiency, reduce environmental impact, and promote circular economy practices. Upcycled ingredients produced in this way offer unique opportunities to create value-added animal-origin foods.

This Special Issue seeks innovative research on strategies for developing upcycled ingredients and reformulating animal-origin food. Manuscripts may focus on, but are not limited to, the following topics:

  • Development of upcycled ingredients from food by-products and waste;
  • Functional, nutritional, and technological properties of upcycled ingredients;
  • Reformulation of animal-origin foods using upcycled ingredients;
  • Safety assessment of both upcycled ingredients and reformulated products;
  • Shelf-life evaluation of both upcycled ingredients and reformulated products;
  • Health-promoting potential of upcycled ingredients;
  • Consumer perception and acceptance of foods containing upcycled ingredients.

Full-length original research and review articles are welcome.

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. Foods 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 2900 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.

The valorization of agro-industrial byproducts has emerged as an important strategy to improve resource efficiency and promote circular food systems. This study evaluated avocado (Persea americana Mill.) seed as a functional ingredient for frankfurter-type sausages using extrusion followed by enzyme-assisted wet milling. Extrusion modified the techno-functional properties of avocado seed flour, increasing the water absorption index from 2.87 to 3.91 g/g while reducing the oil absorption index from 2.12 to 1.84 g/g. In addition, extrusion reduced the total acetogenin content by approximately 82.8% (11.99 to 2.07 mg/g), indicating a substantial reduction of these endogenous compounds. When incorporated at a concentration of 1% (w/w) to replace commercial soy fiber, avocado seed ingredients produced frankfurter-type sausages with low cooking losses (1.67–3.77%), stable water activity (0.979–0.990), and an acceptable instrumental hardness (1.01–1.41 N) over 35 days of refrigerated storage. Consumer sensory evaluation (n = 106) showed comparable or higher flavor and overall acceptability scores for sausages containing avocado seed flour relative to the control formulation. These findings demonstrate that extruded avocado seed flour can function as a viable upcycled ingredient for emulsified meat products, supporting circular bioeconomy approaches for the development of value-added foods of animal origin.
