“…The results for the evaluation of antibacterial activity of pecan nutshell aqueous extract are shown in (Prado et al, 2014). In the present work, aqueous extract was effective to inhibit Gram-negative bacteria such as S. Enteritidis, A. hydrophila and P. aeruginosa, although no inhibition was observed against E. coli.…”

“…Plant extracts possess higher antimicrobial activity compared to pure polyphenols (Puupponen-Pimiä et al, 2001;Prado et al, 2014), suggesting that extracts may exert their action on bacteria due to a combination of different mechanisms. It has been reported that pure polyphenols present antimicrobial activity against Gram-positive and Gram-negative bacteria (Puupponen-Pimiä et al, 2001;Serrano et al, 2009;Prado et al, 2014).…”

“…Pecan nutshell is a phenolic rich agro-industrial byproduct, which polyphenolic profile includes high concentration of gallic acid, chlorogenic acid, p-hydroxybenzoic acid, epigallocatechin and epicatechin gallate (Prado et al, 2014). Due to the elevated concentration of polyphenols, the consumption of its infusion is associated with antioxidant activity, decreasing liver damage, reduction of total cholesterol and action as natural anxiolytic (Malik et al, 2009;Prado et al, 2014;Reckziegel et al, 2011, Müller et al, 2013. Additionally to the benefits to human health, Prado et al (2014) found that pecan nutshell infusion presents antibacterial activity against Gram-positive bacteria such as Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus, Vibrio parahaemolyticus.…”

Evaluation of the antimicrobial activity of pecan nut [Carya illinoinensis (Wangenh) C. Koch] shell aqueous extract on minimally processed lettuce leaves

Pecan nutshell is a residue from food industry that has potential to be used as biopreservative in foods. The objective of this study was to evaluate the antimicrobial activity of pecan nutshell aqueous extract in vitro and its effectiveness to inhibit spoilage microorganisms on lettuce leaves. The results indicate that the aqueous extract presents inhibitory activity against important foodborne pathogenic bacteria such as Listeria monocytogenes, Salmonella Enteritidis, Staphylococcus aureus, Bacillus cereus, Aeromonas hydrophila and Pseudomonas aeruginosa. Antimicrobial activity was not observed against Corynebacterium fimi, Clostridium perfringens, Escherichia coli, and the phytopathogenic fungi tested. When applied onto lettuce leaves, pecan nutshell extract reduced the counts of mesophilic and psychrotrophic bacteria in 2 and 4 log CFU/g, respectively, during storage of leafy for 5 days at refrigeration temperature (5 °C). The extract was not effective to inhibit yeast on lettuce leaves. Thus, the aqueous extract of pecan shell showed great potential to be used as a natural preservative in foods, acting mainly in the inhibition of spoilage and pathogenic bacteria.

Phenolic compounds present in plants have demonstrated several biological properties such as antioxidant, antitumor, cardioprotective, and antiproliferative. On the other hand, doxorubicin, a chemotherapeutic widely used to treat breast cancer, usually exhibits chronic cardiotoxicity associated with oxidative stress. Therefore, we aimed to study the effects of phenolic compound‐enriched extract (PCEE) with doxorubicin in breast cancer. To achieve this, after an SPE‐C18‐column purification process of crude extracts obtained from pecan nutshells (Carya illinoinensis), the resulting PCEE was used to evaluate the cytotoxicity and antioxidant properties against the human breast cancer cell line MDA‐MB‐231 and the normal‐hamster ovary cell line CHO‐K1. PCEE was selectively cytotoxic against both cell lines, with an IC50 value (≈26.34 mg/L) for MDA‐MB‐231 lower than that obtained for CHO‐K1 (≈55.63 mg/L). As a cytotoxic mechanism, PCEE inhibited cell growth by G2/M cell cycle arrest in MDA‐MB‐231 cells. Simultaneously, the study of the antioxidant activity showed that PCEE had a cytoprotective effect, evidenced by reduced ROS production in cells with oxidative stress caused by doxorubicin. The results highlight PCEE as a potential antitumor agent, thus revaluing it as an agro‐industrial residue.

Targeted and Non-Targeted Analyses of Secondary Metabolites in Nut and Seed Processing

Tree nuts and related seeds such as peanuts and oilseeds contain large numbers of secondary metabolites. These compounds have beneficial qualities for human health and wellness, but the reports on them are scattered. The growing field of metabolomics aims to characterize these compounds in a systematic way so that the mechanism of their formation can be better understood. This review gathers current studies using both targeted and non‐targeted approaches to the analysis of secondary metabolites from tree nuts and related oilseeds. Almonds, Brazil nuts, hazelnuts, macadamia nuts, pecan, pine nuts, pistachios, walnuts, peanuts, rapeseeds, and sesame seeds are included along with some lesser known products. The changes with roasting are also discussed. Phenotypic data of this type is useful for identifying specific genetic markers that could be used for crop improvement. High value crops such as tree nuts, peanuts, and oilseeds would benefit from these advances in the understanding of the development of secondary metabolites as they are crucial to seed development, growth, and characteristic flavors. Practical Applications: Tree nuts and seeds are sources of high quality protein and oils worldwide. This review gathers information about more recent studies of the secondary metabolites that are present in these products. The identification and understanding of the mechanism of their formation is needed for expanding the role of tree nuts and related seeds in nutrition and health. A critical review allows for the collection of research on this topic to increase access of the results to those in the field who continue to advance these studies. Nuts and seeds undergo a series of processing steps to produce consumer products. Nuts are harvested from trees, or in the case of peanuts, from plants, either mechanically or by hand. Shelling and cleaning to remove protective outer shells is usually done and then most nuts or seeds are roasted to form desired flavors. Some nuts such as almonds, walnuts, and pecan are often consumed raw. Roasting operations can be either continuous or batch operations. After cooling, nuts are inspected to remove unwanted material and then packaged for retail sale.
