(-Hex) until ≤0.8% residual oil. Protein was extracted from defat ted press cake (PC) using the saline method (0.1 M NaCl, 1: 10 w/v, 50 °C, 2 h) for hexane-defatted wild-type pennycress (WTP) seed meal and PC. TT8 PC had 33%–67% more globulin and glutelin than WTP PC, but ethanol defatting reduced albumin + globu lin amounts by 14%–32%. TT8 PC protein recoveries (63% and 40%) were 2- to 3-fold greater than that of Y1126 PC-Eth and their extracts had greater purity (85%–91% vs. 70% protein). Y1126 PC-Eth protein showed a nearly constant 68%–70% solubility from pH 2 to 10, but TT8 PC-Eth protein was more soluble in acidic pH (87%–90% solubility). Y1126 PC-Eth protein showed greater foaming capacity (146–150 mL), while TT8 PC-Eth protein had superior emulsifying properties (EAI 141–236 m 2 /g protein and ESI 13–26 min). This work demonstrated the enhanced functional ity of TT8 and Y1126 proteins produced from an environmentally friendly and industrially relevant method. Novel palm shortening substitute using a combination of rapeseed oil, linseed meal and beta-glucan Sampaio, S.L., et al. , Food Chemistry , 457, 140134, 2024. https://doi.org/10.1016/j.foodchem.2024.140134 This study investigated the potential of a novel sustainable ingredient composed of rapeseed oil, linseed meal and beta-glu can (PALM-ALT) to mimic palm shortening functionality in

porated in food products. ALA bioaccessibility was lower than 34 % in raw oil, while increased when CO was incorporated in CKO (40.06 ± 0.83 %), thus indicating a protecting activity within the food matrix. These results confirmed that CKO could represent a suitable food to deliver camelina oil essential fatty acids, even if an additional optimization of the formulation is required to further improve ALA bioaccessibility. Cold-pressing, ethanol defatting, and saline extraction enhances properties of protein products from new pennycress varieties (covercress™) Hojilla-Evangelista, M.P., et al. , Sustainable Food Proteins , 1-16, 2024. https://doi.org/10.1002/sfp2.1029 Pennycress ( Thlaspi arvense L.), a winter oilseed and cover crop, is a source of novel proteins and oil for biofuel. New yellow seeded pennycress specialty varieties, named covercress™, were developed via conventional breeding and gene editing, but protein characteristics are still unknown. This work evaluated two cover cress lines, TT8 and Y1126, for protein extraction and functionality, and the combination of cold-pressing, alcohol-defatting, and saline extraction to produce a protein that could align better with clean labeling. Seeds were first cold-pressed in a tubular radial expel ler then defatted at 60 °C with anhydrous ethanol (-Eth) or hexane
