    查看更多>>摘要:Flaxseed milk coproduct(FMC)is a by-product of flaxseed milk.Okara is a by-product of processed soybean products.In this study,we investigated the quality of dough and Chinese steamed bread(CSB)with the addition of FMC and okara.We also examined the in vitro starch digestibility,expected glycemic index(eGI),starch crystallinity,and short-range order structure of CSB.The results showed that FMC and okara decreased the dough fluidity,formed a dense structure,and enhanced the mechanical properties of the dough.FMC and okara increased the hardness,gumminess,and chewiness of the CSB,while decreasing its cohesion and elasticity.The addition of FMC and okara improved the nutrient content of CSB and reduced the eGI from 75.86 to 51.56.FMC and okara altered the multiscale structure of starch,effectively shielding the amylase site of action,and limited the interaction between amylase and starch.This study provides a reference for the high-value utilization of oilseed processing by-products.

    查看更多>>摘要:Structural variations(SVs),a newly discovered genetic variation,have gained increasing recognition for their importance,yet much about them remains unknown.With the completion of whole-genome sequencing projects in oil crops,more SVs have been identified,revealing their types,genomic distribution,and characteristics.These findings have demonstrated the crucial roles of SVs in regulating gene expression,driving trait innovation,facilitating domestication,making this an opportune time for a systematic review.We summarized the progress of SV-related studies in oil crops,focusing on the types of SVs and their mechanisms of occurrence,the strategies and methods for SV detection,and the SVs identified in oil crops such as rapeseed,soybean,peanut,and sesame.The various types of SVs,such as presence-absence variations(PAVs),copy number variations(CNVs),and homeol-ogous exchanges(Hes),have been shown.Along with their genomic characterization,their roles in crop domestication and breeding,and regulatory impact on gene expression and agronomic traits have also been demonstrated.This review will provide an overview of the SV research process in oil crops,enabling researchers to quickly understand key information and apply this knowledge in future studies and crop breeding.

    查看更多>>摘要:In order to select an appropriate deacidification process and improve the quality of walnut oil,low-temperature cold-pressed crude walnut oil was used as raw material.Deacidified walnut oil was prepared using three deacidification processes:chemical deacidification(CD),adsorption deacidification(AD),and molecular distil-lation deacidification(MDD).The physicochemical properties,nutritional components,and in vitro antioxidant activities of the resulting deacidified walnut oils were comparatively analyzed.The results indicate that the fatty acid content in walnut oil exhibits fluctuating changes during the three different deacidification processes.The MDD shows a higher deacidification rate,reaching 94.06%,which is superior to the other two methods.Addi-tionally,the AD retains more total phenols and tocopherols,with retention rates of 95.79%and 74.62%,respectively;whereas MDD is more effective at retaining phytosterols,achieving a retention rate of 98.09%.All these methods displayed positive impacts on the in vitro antioxidant capacity and oil stability of walnut oil,with ferric-reducing antioxidant power(FRAP)content and oxidative stability time were significantly reduced.-whencompared to the untreated crude oil Among them,AD had the greatest impact on oxidative stability index(OSI),with its decreasing from 2.06 h to 0.82 h.Overall,compared to CD or MDD,the AD has best application prospects in preserving nutritional components.

    查看更多>>摘要:The Tangier-Tetouan-Al Hoceima(TTA)region is one of the main olive oil producing regions in Morocco.Little is devoted to characterize olive oil physicochemical traits from TTA hence the originality of this study.It aimed at investigating variation in olive oil quality produced from three Moroccan cultivars'Moroccan Picholine','Menara',and'Haouzia'and their blends.Sampling was performed in five provinces fromTTA(Northern Morocco)during four consecutive crop-seasons(2018-2021)considering three extraction technologies(ET):traditional discontinuous press system(SP)and continuous extraction systems including decanter of three outlets(3O)and decanter of two outlets(2O).Physicochemical measurements consisted of routinely quality parameters namely free acidity(FA),peroxide value(PV),UV absorption parameters(K232,K270,and ΔK),chlorophylls(Chl)and carotenoids(Car)contents,total phenolic compounds(TPC)and oxidative stability(OS).Crop season showed its superiority impacts on K232,OS,TPC,Chl,and OS.While cultivar was the main variability source in both PV and K270,and FA was mainly determined by ET.Important variations(p<0.05)were reported among crop seasons and locations due to pedoclimatic differences.'Menara'and'Haouzia'had higher pigments content,TPC,and OS,and the blends displayed low pigments concentration,TPC,and OS.Expectedly,continuous ET(2O and 3O)had the greatest values of pigments content,TPC,and OS as revealed by principal component analysis.Strong correlations were highlighted among basic quality parameters,TPC,pigments,and OS.Simple linear regression was used to describe the relationships between OS and TPC(R2=0.856)and OS regressed against Chl(R2=0.690)and Car(R2=0.760),while TPC were regressed on Chl(R2=0.670)and Car(R2=0.680)and finally Chl against Car(R2=0.931).In conclusion,compared to technological,genotypic,and geographic effects,climatic conditions were the main factor driving olive oil stability and associated phenolics and pigments;oil cultivar blend seems to have negative effects on pigments concentration and total phenolic compounds as well as oxidative stability.

    查看更多>>摘要:Peanut(Arachis hypogaea L.)is an important oil crop.Oleic acid is a major factor that determines the quality of peanuts.Therefore,the high oleic and high oleic to linoleic acid ratio are the target traits in an advanced peanut breeding program.This study provided an extensive evaluation of the genetic and physical characteristics as well as disease resistance of 220 high oleic peanut varieties in China.Notably,these varieties clustered into five major categories based on their traits.A majority of these varieties have been bred using interspecific hybridization or selected from mutants of self-crossed parents,with the main parent varieties being Kaixuan 016 and CTWE.Analysis of disease resistance showed that most high oleic peanut varieties could resist two or three diseases.However,those varieties with resistance to multiple diseases were relatively scarce.Moreover,some high oleic peanut varieties showed no disease resistance or inadequate testing.The results further indicate that the genetic basis for high oleic peanut breeding is insufficient,highlighting the need for its further development.Importantly,our findings lay a critical foundation for future high oleic peanut breeding and promote better understanding of the genetic and trait diversity offered by these varieties.
