Partial replacement of wheat flour by pecan nut expeller meal on bakery products. Effect on muffins quality
The objective of the present work was to evaluate the effect of replacing up to 40 g/100 g wheat flour by pecan nut expeller meal on baking quality of a typical muffin formulation. Baked samples were subjected to several assays: yield, height of the specimen, color, crumb moisture, texture (TPA), microstructure by image analysis. Replacement of 30 g/100 g of wheat flour by expeller significantly height of the product. Also hardness was greatly reduced (52.4%) when 30 g/100 g of PEM was included. The addition of PEM lead to a darker crumb, the browning index was 38% higher when 40 g/100 g of wheat flour was ...

Lignin and holocellulose from pecan nutshell as reinforcing fillers in poly (lactic acid) biocomposites.
Abstract
Lignocellulose from agro-food biowaste represents a valuable source of cost-effective structural fillers for wholly renewable polymer composites. In this work, pecan (Carya illinoinensis) nutshell (NS) fiber and its structural components, holocellulose (HC) and acid insoluble lignin (AIL), were isolated, characterized and used as reinforcing fillers to manufacture poly(lactic acid) (PLA) based biocomposites. Thermal, morphological and mechanical properties of the prepared materials were analyzed. NS and HC acted as heterogeneous nucleating agents, potentially able to control PLA physical aging. Mo...

Identification and hydrolysis kinetic of a novel antioxidant peptide from pecan meal using Alcalase
In this study, the hydrolysis of a pecan protein isolate (PPI) with Alcalase was carried out to generate antioxidant peptides. We proposed a kinetic model to illustrate the enzymolysis process of PPI, which was found suitable for depiction of the kinetic behavior for PPI hydrolysis by Alcalase. The PPI hydrolysis products were gradually fractionated by ultrafiltration through cut-off membranes with molecular weights of 10, 5 and 3 kDa and their antioxidant activities were evaluated in vitro. Further, the strongest antioxidant fraction (<3 kDa) and novel antioxidative peptide were successfully purified. The amino...

Molecules, Vol. 23, Pages 435: Dynamic Changes in Phenolics and Antioxidant Capacity during Pecan (Carya illinoinensis) Kernel Ripening and Its Phenolics Profiles
Liangju Wang
Pecan (Carya illinoinensis) kernels have a high phenolics content and a high antioxidant capacity compared to other nuts—traits that have attracted great interest of late. Changes in the total phenolic content (TPC), condensed tannins (CT), total flavonoid content (TFC), five individual phenolics, and antioxidant capacity of five pecan cultivars were investigated during the process of kernel ripening. Ultra-performance liquid chromatography coupled with quadruple time-of-flight mass (UPLC-Q/TOF-MS) was also used to analyze the phenolics profiles in mixed pecan kernels. TPC, CT, TFC, individual phenolics...

Genes, Vol. 9, Pages 71: Transcriptomic Analysis Provides Insights into Grafting Union Development in Pecan (Carya illinoinensis)
gren Peng
Pecan (Carya illinoinensis), as a popular nut tree, has been widely planted in China in recent years. Grafting is an important technique for its cultivation. For a successful grafting, graft union development generally involves the formation of callus and vascular bundles at the graft union. To explore the molecular mechanism of graft union development, we applied high throughput RNA sequencing to investigate the transcriptomic profiles of graft union at four timepoints (0 days, 8 days, 15 days, and 30 days) during the pecan grafting process. After de novo assembly, 83,693 unigenes were obtained, and 40,069 o...

Multimeric recombinant antibody (scFv) for ELISA detection of allergenic walnut. An alternative to animal antibodies
Publication date: April 2018 Source:Journal of Food Composition and Analysis, Volume 67 Author(s): Raquel Madrid, Silvia de la Cruz, Aina García-García, Marcos J.C. Alcocer, Isabel González, Teresa García, Rosario Martín Walnuts are classified as an important allergenic ingredient that can cause severe reactions in sensitized individuals. To prevent unintended exposure to products containing walnut, food manufacturers have the responsibility to declare its presence in packaged foods. Immunochemical methods are widely used to detect walnut proteins. However, available immunoassays rely on the use of antibodies...

Nut Oral Immunotherapy (NOIT) for Allergy to One Nut Desensitizes to the Cross Reactive Nut
Nut oral immunotherapy (NOIT) has gained increasing popularity over the past ten years but remains a burdensome therapy. There is significant cross-reactivity between cashew and pistachio nuts and between pecan and walnuts. Patients were treated with NOIT to one of the cross-reactive nut pairs and then challenged to the other member of the dyad. (Source: Journal of Allergy and Clinical Immunology)

Tree Nut Cross-Reactivity Based on Clinical Allergy Testing
Tree nuts(TNs) are common food allergens in children and adults. Sensitization to more than one TN is often observed. Cross-reactivity between cashew/pistachio and walnut/pecan has been reported based on similar epitopes and phylogenetic homology. However, clinical cross-reactivity data is lacking. We hypothesize that clinical testing will correlate with molecular data. (Source: Journal of Allergy and Clinical Immunology)

Pecan phenology in Southeastern China
Abstract
Pecan (Carya illinoensis) is heterodicogamous, which often leads to unstable yield of its nut crops. Relating pecan orchard management to the phenological stage of the trees is the key to increasing yields; however, describing morphology alone does not lead to an orchard management system that is simple and practical. In this work, we extend the BBCH (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie) coding method to describe the morphology of the protogynous Mahan pecan cultivar over two consecutive years in southern China. Eight main growth stages, from vegetative bud dormancy to fruit harvest,...

Use of superheated steam to inactivate Salmonella enterica serovars Typhimurium and Enteritidis contamination on black peppercorns, pecans, and almonds
This study investigated the inactivation efficacies and kinetics of superheated steam (SHS) treatment of black peppercorns, pecans, and almonds inoculated with a cocktail of Salmonella Typhimurium and Salmonella Enteritidis. According to D- and z-values determined from the Weibull model, Salmonella inactivation efficacy increased as the steam temperature increased, and the sensitivity to changes in the SHS temperature was the highest for black peppercorns, followed by pecans and almonds, which is attributable to the differences in the surface properties of the foods. Furthermore, Salmonella inoculated on black peppercorns,...
