However, due to their high content of unsaturated fatty acids (UFAs), the quality of walnuts tends to decline during storage, which adversely affects the development of the walnut industry. This study was aimed to investigate the impacts of temperature and packaging methods on the storage quality and oxidative stability of walnuts. The Wen 185 walnut variety was selected, and the physical-chemical and nutritional indexes of walnuts stored for 42 weeks under different temperatures (−18 ​°C, 4 ​°C, and room temperature) and packaging methods (vacuum light-exposed, vacuum light-proof, vacuum-radiation light-exposed, vacuum-radiation light-proof, nitrogen-filled light-exposed, nitrogen-filled light-proof) were measured. The results showed that low temperatures, especially −18 ​°C, in combination with vacuum lightproof packaging, could effectively suppress the increase in oxidative stability indicators such as acid value (AV) and peroxide value (PV), and maintain high retention rates of nutritional indicators like tocopherol and phytosterol. This study has elucidated that low temperatures and appropriate packaging methods play the crucial roles in maintaining the quality and oxidative stability of walnuts during storage. It has provided comprehensive and valuable data support and theoretical basis for the scientific storage of walnuts, contributing to the development of the walnut industry and the guarantee of product quality.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 3","pages":"Pages 212-222"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses these limitations by formulating a double nano-emulsion (W/O/W) system incorporating macadamia oil and tea tree oil, using homogenization and phase inversion temperature (PIT) techniques. Comprehensive physicochemical characterization, including droplet size, polydispersity index (PDI), zeta potential, turbidity, Fourier transform infrared spectroscopy (FTIR), and SEM, was conducted alongside stability assessments under varying pH, temperature, and storage conditions. The optimized nano-emulsions exhibited nanoscale droplet sizes (10–40 ​nm), low PDI values (indicating high uniformity), and robust stability. Interestingly, the formulation with 2% W/O loading, with a particle size of 11.57 ​nm and a PDI of 0.04, demonstrated an antioxidant capacity of 4622.62 ​μg ascorbic acid equivalents (AA)/g, which was significantly higher (p ​&lt; ​0.05) compared to both natural oils (macadamia oil: 20.91 ​μg AA/g, tea tree oil: 16.86 ​μg AA/g) and a 10% Vitamin C aqueous solution (592.94 ​μg AA/g). FTIR analysis confirmed the molecular integrity of Vitamin C and its successful encapsulation with macadamia and tea tree oils, while SEM images revealed uniformly spherical and well-dispersed droplets. Moreover, the formulation retained its structural integrity and antioxidant functionality under diverse pH and thermal conditions. These findings underscore the potential of double nano-emulsion systems to overcome the stability challenges of Vitamin C, offering a promising approach to enhance its bioavailability and therapeutic performance in pharmaceutical and cosmetic applications.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145098757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Findings show that high reciprocal tariffs caused a 75% drop in U.S. soybean exports to China. Palm oil, with high yield efficiency and cost-effectiveness, offers a viable supplement to fill supply chain gaps. Promoting oil palm cultivation through northward expansion and cooperation with Belt and Road countries is recommended.

However, the impact of ARC microbial inoculants on different resistant varieties of <em>A</em>. <em>flavus</em> remains unclear. In this study, we screened peanut varieties that were resistant and susceptible to <em>A. flavus</em> and evaluated their nodulation ability and growth performance after ARC microbial inoculants treatment in the field. The results demonstrated that the nodule number and nitrogenase activity of both varieties significantly increased after ARC microbial inoculants treatment, with the highly susceptible variety AH24 showing a greater increase. For photosynthetic parameters, both varieties also increased after ARC microbial inoculants treatment, but the increase was greater in the moderately resistant variety AH1 than in the highly susceptible variety AH24. Finally, we found that the yield and yield-related traits of the moderately resistant variety AH1 were better than those of the highly susceptible variety AH24. After ARC microbial inoculants treatment, the yield traits of both peanut varieties still increased significantly, but the degree of increase of the moderately resistant variety AH1 was smaller than that of the highly susceptible variety AH24. In addition, the abundance of <em>A. flavus</em> in the rhizosphere soil of the two varieties significantly decreased after ARC microbial inoculants treatment, with no significant difference between the varieties. These results indicated that ARC microbial inoculants exert differential effects on the nodulation and growth of different resistant peanut varieties and have a better effect on highly susceptible varieties.
