FT-IR spectrum of Locust migratoria protein concentrates considering the extraction methods

The document presents FT-IR spectra of insect protein concentrates from Locusta migratoria, Acheta domesticus, and Tenebrio molitor obtained using different extraction methods. The four methods analyzed include: Method I (control, alkali extraction-acid precipitation, AE-AP), Method II (salting-in-AE-AP), Method III (AE-AP-salting-out), and Method IV (salting-in-AE-AP-salting-out). These spectra help assess structural changes in proteins due to different isolation techniques, providing insights into their functional properties and potential applications.
