Protein extraction yield, lipid composition, and emulsifying properties of aqueous extracts of Rhynchophorus phoenicis larvae extracted at pH 3.0 to 10.0.

•Proteins were extracted from Rhynchophorus phoenicis (Rp) larvae by buffers (pH 3–10).•The Rp protein extraction yield and lipids were the highest at alkaline pHs (9–10).•The co-extracted lipids contained at alkaline pHs high levels of free fatty acids;.•The pHs 9.0 and 10.0 aqueous extracts of Rp larvae stabilize oil-in-water emulsions.•Alkaline pHs are suitable to extract and prepared protein concentrate/isolate of Rp.
