Pine nut oil (PNO) is highly valued by consumers for its rich content of unsaturated fatty acids, which confer unique nutritional benefits. However, PNO is highly susceptible to lipid oxidation during storage and extraction. This chemical degradation compromises product quality and poses potential risks to food safety. To address this challenge, the food industry is developing antioxidant strategies, including optimizing pretreatment conditions to improve flavor and storage stability. Green extraction technologies such as microwave-assisted extraction (MAE) and ultrasonic-assisted extraction (UAE) have been introduced to enhance extraction efficiency and promote environmental sustainability. Light-proof packaging, reduced oxygen environments, and temperature control have also been employed to significantly extend the shelf life of PNO. Furthermore, to maintain the nutritional integrity and safety of PNO while expanding its functional applications in the food industry, several innovative approaches have been employed. These include the incorporation of natural antioxidants, the development of Pickering emulsions, the use of microencapsulation, and the formulation of oleogels.

Accurate identification of -18:3 fatty acid isomers remain challenging due to the co-elution of structurally diverse isomers, particularly non-methylene-interrupted fatty acids (NMIFAs). GC-FID analysis of pine nut using an SP™-2560 column revealed unusually high peak areas (> 13%) in the 18:3t region. However, a peak reduction in the 18:3t region after nitric acid-induced isomerization reaction, suggested the presence of isomers in native pine nut.

D ifferent samples may cause various types of matrix interference in lateral flow immunoassay (LFA), while deep eutectic solvents (DESs) as emerging green solvents can be synthesized to adapt to different extraction processes by adjusting the composition of hydrogen bond donors (HBDs) and hydrogen bond acceptors (HBAs). Initially, 30 types of food samples were selected to explore the total dilution factors (tDFs) and limit of detection (LODs) on AFB detection by acetonitrile/water extraction. The matrix effect may be induced by some food matrices with high-fat content, including pumpkin seed kernel, almond, pecan, black sesame seed, walnut, and pine nut (tDFs exceeding 70-fold).

Background: The European Regulation list on mandatory labelling of foods includes 14 allergenic foods; however, other foods are also frequently implicated in food-induced anaphylaxis (FIA).
Methods: We analysed FIA cases reported to the Allergy Vigilance Network from 2002 to 2023. Allergenic foods involved in ≥ 1% of cases and not included in the list were assessed as emerging food allergens (EFA).

A high intake of saturated fats and cholesterol from processed meats is associated with increased cardiovascular disease risk. This study aimed to develop a nutritionally enhanced Bologna-type sausage by partially replacing the beef content with a structured emulsion gel (EG) formulated from pine nut oil, inulin, carrageenan, and whey protein concentrate. The objective was to improve its lipid quality and functional performance while maintaining product integrity and consumer acceptability.

This study investigated the effects of natural seed coats on quality formation of roasted pine nuts and underlying mechanisms. The intact seed coat imparted ideal crispness to the roasted pine nuts, improved paste properties (including cohesion, consistency index, viscoelastic modulus, and thixotropic recovery properties), and increased active compounds/antioxidant activity, reducing total lipid oxidation value by 45.03 %.
