The purpose of this study was to assess long chain polyunsaturated fatty acid (LCPUFA) status in relation to socio-behavioral outcomes in children with Attention Deficit/Hyperactivity Disorder (AD/HD). In a case-control design, plasma phospholipid fatty acid content was assessed in children aged 5–12 years with AD/HD and in typically functioning children. Dietary intakes of LCPUFAs arachidonic acid (AA; 20:4n6) and docosahexaenoic acid (DHA; 22:6n3) were quantified using a four-day food record, polymorphisms were determined in FADS1 and FADS2, and socio-behavioral outcomes were assessed using the Conners 3 Parent Rating Scales in a cross section of children with AD/HD. Compared to …


Weakly-Supervised Learning Method For The Recognition Of Potato Leaf Diseases, Junde Chen, Xiaofang Deng, Yuxin Wen, Weirong Chen, Adnan Zeb, Defu Zhang Dec 2022

Weakly-Supervised Learning Method For The Recognition Of Potato Leaf Diseases, Junde Chen, Xiaofang Deng, Yuxin Wen, Weirong Chen, Adnan Zeb, Defu Zhang

As a crucial food crop, potatoes are highly consumed worldwide, while they are also susceptible to being infected by diverse diseases. Early detection and diagnosis can prevent the epidemic of plant diseases and raise crop yields. To this end, this study proposed a weakly-supervised learning approach for the identification of potato plant diseases. The foundation network was applied with the lightweight MobileNet V2, and to enhance the learning ability for minute lesion features, we modified the existing MobileNet-V2 architecture using the fine-tuning approach conducted by transfer learning. Then, the atrous convolution along with the SPP module was embedded into the …


Species Substitution And Mislabeling Of Ceviche, Poke, And Sushi Dishes Sold In Orange County, California, Courtney J. Kitch, Amanda M. Tabb, Grace E. Marquis, Rosalee S. Hellberg Nov 2022

Species Substitution And Mislabeling Of Ceviche, Poke, And Sushi Dishes Sold In Orange County, California, Courtney J. Kitch, Amanda M. Tabb, Grace E. Marquis, Rosalee S. Hellberg

Raw, ready-to-eat (RTE) seafood products have become increasingly popular globally, but they are vulnerable to species substitution and mislabeling. DNA barcoding allows for fish species identification by extracting, amplifying, and sequencing a standardized gene target. A wide variety of fish products have been studied with DNA barcoding, but little investigation of ceviche and poke has occurred in the United States. Sushi is known to be a target of mislabeling but has not been extensively studied in Orange County, CA. The objective of this study was to investigate species substitution and mislabeling of sushi, poke, and ceviche dishes sold at restaurants …


Application Of The Weibull Model To Describe The Kinetic Behaviors Of Thiol Decolorizers In Chlorogenic Acid-Lysine Solutions, Charles Taylor Drucker, Lilian Were Senger, Criselda Toto Pacioles Sep 2022

Application Of The Weibull Model To Describe The Kinetic Behaviors Of Thiol Decolorizers In Chlorogenic Acid-Lysine Solutions, Charles Taylor Drucker, Lilian Were Senger, Criselda Toto Pacioles

Food Science Faculty Articles and Research

Thiols (cysteine and glutathione) were explored as potential decolorization agents to mitigate green pigment formation in chlorogenic acid quinone-lysine solutions. Reparameterizations of the Weibull cumulative distribution function were applied to describe the time-dependence of greening under varying pH conditions. Repeated fitting of 3-parameter models (RMSE = 0.0111, CVRMSE = 1.55%) indicated the linear dependence of model parameters on thiol concentration. A 6-parameter Weibull model incorporating time and initial thiol concentration (RMSE = 0.0255, CVRMSE = 3.56%) accurately predicted green color development. Calculated model parameters descriptive of greening rate, terminal greening magnitude, and lag time before greening onset facilitated comparison of …


Effectiveness Of Selected Pre-Enrichment Broths For The Detection Of Salmonella Spp. In Meat Analogs, Georgia L. Sampson, Shannon B. Ruelle, Lieuchi Phan, Donna Williams-Hill, Rosalee S. Hellberg Aug 2022

Effectiveness Of Selected Pre-Enrichment Broths For The Detection Of Salmonella Spp. In Meat Analogs, Georgia L. Sampson, Shannon B. Ruelle, Lieuchi Phan, Donna Williams-Hill, Rosalee S. Hellberg

Food Science Faculty Articles and Research

With the increasing variety of meat analog products, it is important to verify that the methods used for Salmonella detection are effective. The objective of this study was to compare the efficacy of three pre-enrichment broths for the detection of Salmonella in meat analog burgers: the currently used Bacteriological Analytical Manual (BAM) broth (lactose broth with Triton X-100, LB-T), universal pre-enrichment (UP) broth, and buffered peptone water (BPW). Five different meat analog products (coded A-E) were inoculated with Salmonella serotypes (S. Enteritidis or S. Agona) following the Food and Drug Administration Method Modification and Method Extension Criteria for Existing …


Characterization Of Gangliosides And Fatty Acids In Extracellular Vesicles From Human Milk, Aliya Amin May 2022

Characterization Of Gangliosides And Fatty Acids In Extracellular Vesicles From Human Milk, Aliya Amin

Food Science (MS) Theses

Extracellular vesicles (EVs) are bioactive components of human milk that may impact functionality to regulate growth, cognitive development, metabolism, and immunity in newborns. The biogenesis of EVs and the mechanism by which EVs elicit biologic effects in vivo have not been characterized entirely. Gangliosides and fatty acids are integral in the formation, release, stability, and functionalities of EVs. Presumably, EV function is related to EV composition and lipids in EVs influence the bioavailability of EV cargo and downstream functions of EVs. The objective of this research was to characterize the fatty acid and ganglioside composition of EVs in human milk. …

Some new cassava accessions have been developed and released because of their high yield, resistance to disease, adaptability to wider ecological environment, and less cost of production. However, their flour and starch properties have not been characterized for potential food applications. In the present study, starch and flour were produced from two new cassava accessions (Sika Bankye and Bankye Hemaa) and evaluated for their physicochemical and pasting properties. The flour samples recorded higher values for the various functional parameters compared to their starch counterparts. Both flour samples had a similar water absorption capacity (WAC) of ~263% but the associated …

Purpose: A systematic review was conducted to assess how the involvement of a registered dietitian nutritionist (RDN) in healthy behavior interventions (HBIs) potentially affects outcomes in older adults with type 2 diabetes (T2D).

Methods: Literature was searched for primary research published between 2016 and 2020 on HBI involving a RDN affecting outcomes in older adults with T2D. Evaluations of hemoglobin A1c (HbA1c), blood glucose, blood pressure, cholesterol, anthropometry, body composition, medication usage, healthcare cost, and self-efficacy and/or adherence to healthy behaviors outcomes were selected for inclusion. All the literature included were summarized, evaluated for certainty of evidence criteria, and assessed …
