“…Most animal-based processing by-products are resistant to degradation and require pretreatment with chemical reagents, such as sulfuric acid, hydrochloric acid, and sodium hydroxide [47]. This pretreatment method requires long reaction times and generates large amounts of waste liquid that pollute the environment.…”

Steam explosion technology is an emerging pretreatment method that has shown great promise for food processing due to its ability to efficiently destroy the natural barrier structure of materials. This narrative review summarizes the principle of steam explosion technology, its similarities and differences with traditional screw extrusion technology, and the factors that affect the technology. In addition, we reviewed the applications in food processing by-products in recent years. The results of the current study indicate that moderate steam explosion treatment can improve the quality and extraction rate of the target products. Finally, we provided an outlook on the development of steam explosion technology with a reference for a wider application of this technology in the food processing field.

“…The resulting nutrient‐rich digestate may be used in agriculture (Salminen and Rintala, 2002 ). Hooves can also be treated using urea (to break non‐covalent bonds), sodium dodecyl sulfate (for disruption of strong intermolecular interactions) and mercaptoethanol (to cleave the disulfide bonds in keratin), at 60°C, to get keratin in aqueous solution first and a lyophilised form afterwards (Shen et al., 2020 ).…”

The European Commission requested EFSA to assess if different thermal processes achieve a 5 log 10 reduction in Enterococcus faecalis or Salmonella Senftenberg (775W) and (if relevant) a 3 log 10 reduction in thermoresistant viruses (e.g. Parvovirus ) as well as if different chemical processes achieve a 3 log 10 reduction of eggs of Ascaris sp., in eight groups of Category 2 and 3 derived products and animal by‐products (ABP). These included (1) ash derived from incineration, co‐incineration and combustion; (2) glycerine derived from the production of biodiesel and renewable fuels; (3) other materials derived from the production of biodiesel and renewable fuels; (4) hides and skins; (5) wool and hair; (6) feathers and down; (7) pig bristles; and (8) horns, horn products, hooves and hoof products. Data on the presence of viral hazards and on thermal and chemical inactivation of the targeted indicator microorganisms and biological hazards under relevant processing conditions were extracted via extensive literature searches. The evidence was assessed via expert knowledge elicitation. The certainty that the required log 10 reductions in the most resistant indicator microorganisms or biological hazards will be achieved for each of the eight groups of materials mentioned above by the thermal and/or chemical processes was (1) 99–100% for the two processes assessed; (2) 98–100% in Category 2 ABP, at least 90–99% in Category 3 ABP; (3) 90–99% in Category 2 ABP; at least 66–90% in Category 3 ABP; (4) 10–66% and 33–66%; (5) 1–33% and 10–50%; (6) 66–90%; (7) 33–66% and 50–95%; (8) 66–95%, respectively. Data generation on the occurrence and reduction of biological hazards by thermal and/or chemical methods in these materials and on the characterisation of the usage pathways of ABP as organic fertilisers/soil improvers is recommended.
