Fat replacement by pecan nut and oregano oil and their impact on the physicochemical properties and consumer acceptability of frankfurters.
Objective: A study was conducted to determine the physicochemical quality and consumer acceptability of beef frankfurter-type sausages formulated with pecan nut paste and Mexican oregano oil (MO) of two varieties, Poliomintha longiflora Gray or Lippia berlandieri. Methods: Frankfurters were processed under six treatment conditions: control (10.67% pork fat), MOP (control + 0.01% MOP), MOL (control + 0.01% […]
The Effects of Pecan Shell, Roselle Flower and Red Pepper on the Quality of Beef Patties during Chilled Storage.
The antioxidant and antimicrobial effects of pecan shell (PSW), combined with roselle flower (RS) and red pepper (CA) were analyzed in beef patties by several methods during chilled storage for 13 days. Additionally, the antioxidant and antimicrobial activities of PSW, RS and CA extracts were determined. The PSW extract exhibited a higher radical scavenging activity […]
Effects of Postharvest Handling and Storage on Pecan Quality.
The United States is the world’s leading producer, consumer and exporter of pecans and currently experiencing high demand for pecans from countries around the world. Environmental factors such as temperature, RH, light, etc., under pecan storage, transportation, and distribution can adversely affect its quality attributes such as color, texture, oil quality, and phytochemical content. The […]
A Prospective Validation of the NUT CRACKER Diagnostic Algorithm for Walnut and Pecan Allergy with Prediction of Severity.
Background: We previously devised an algorithm utilizing skin prick tests (SPT), basophil activation tests (BAT) and co-allergy status to reduce the need for oral food challenges (OFC) in 63 patients with suspected walnut/pecan allergies. Objective: To validate prospectively the NUT CRACKER diagnostic algorithm in a new cohort of patients (n=120) and to study the utility […]
Characterization of pecan shells and their effect on the physical properties and acceptability of smoked chicken breast.
Pecan shells were used as a source of smoke for cooked chicken breast and compared with samples smoked with hickory, mesquite, and apple tree wood. The wood moisture content ranged from 7.94% to 11.43%, whereas ash ranged from 0.97% to 3.11%. The particle size varied among the smoke sources, with chopped pecan shells having more […]
Chemical composition and oxidative stability of eleven pecan cultivars produced in Southern Brazil.
Nuts are considered highly nutritious foods and a source of health-promoting compounds. Therefore, the aim of this study was to evaluate the chemical composition (proximate composition, fatty acids, volatile compounds, total phenolics, squalene, and β-sitosterol) of eleven pecan cultivars harvested in Rio Grande do Sul State (Brazil) and investigate their oxidative stability by the Rancimat […]
A comparison of fatty acid and sensory profiles of raw and roasted pecan cultivars.
Five fatty acids comprise the bulk of the lipid content in pecans: palmitic acid, stearic acid, oleic acid, linoleic acid, and linolenic acid. Understanding the profiles of these fatty acids and how they relate to sensory characteristics may offer an explanation for flavor and flavor defects that may exist in certain cultivars of pecans. The […]
Edible Nuts for Memory.
Nuts hold prime significance throughout the world as they offer multiple health benefits owing to their highly nutritious profile. A number of scientific studies have demonstrated their actions against inflammation, oxidative damage, the aging process, as well as dementia or memory loss. However, only walnuts, followed by almonds, hazelnuts and pistachios, have shown promising results […]
Antioxidant Properties of Agri-food Byproducts| and Specific Boosting Effects of Hydrolytic Treatments.
Largely produced agri-food byproducts represent a sustainable and easily available source of phenolic compounds, such as lignins and tannins, endowed with potent antioxidant properties. We report herein the characterization of the antioxidant properties of nine plant-derived byproducts. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing/antioxidant power (FRAP) assays indicated the superior activity of pomegranate peels and seeds, grape […]
A comparison of ground-based air-blast sprayer and aircraft application of fungicides to manage scab in tall pecan trees.
Pecan scab (caused by Venturia effusa) is a destructive disease of pecan in the southeastern United States. Susceptible cultivars must be sprayed with fungicide every 10 to 21 days to ensure yield and kernel quality. Fungicide is most often applied using large orchard air-blast sprayers. Pecan trees grow tall, and air-blast sprays result in a gradient […]
