- Pecan nut expeller cake (PNEC), a by-product of pecan oil extraction, was characterized and the effect of packaging and storage conditions was investigated. Samples were packaged under vacuum or in normal atmosphere and stored (10 or 20 ºC) for 12 months. Its composition, water and oil absorption, fatty acids profile, lipid oxidation (thiobarbituric acid reactive substances, TBARS), antioxidant activity [Diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl] radical, DPPH• and [(2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)] radical cation, ABTS•+), and microbiological quality were analyzed. PNEC showed high lipid and fiber contents (51.4 and 21.6 g/100g, respectively) with good water and oil absorption capacity. Vacuum storage at 10 ºC preserved antioxidant capacity (TBARS: malondialdehyde= 0.23 mg/kg, IC50 DPPH = 9.0 mg/mL, and IC50 ABTS = 21 mg/mL after one year storage). Extremely low mold and yeast levels were found in PNEC in low permeability vacuum packages, regardless of the storage temperature. Thus, PNEC could retain suitable quality attributes for up to 12 months using the right combination of packaging and temperature.
La torta de prensada de nuez de pecan (PNEC), un sub-producto dela extracción de aceite de pecan, fue caracterizado y se investigó el efecto del embalaje y condiciones de almacenamiento. Las muestras fueron envasadas con y sin vacío y almacenadas (10 o 20ºC) durante 12 meses. Se analizó la composición, absorción de agua y aceite, perfiles de ácidos grasos, oxidación lipídica (sustancias reactivas al ácido tiobarbitúrico, TBARS), actividad antioxidante [radical (difenil-1-(2,4,6-trinitrofenil) hidracilo] DPPH• y catión radical [ácido (2,2′-azinobis-(3-etilbenzotiazolin-6-sulfónico)], ABTS•+) y calidad microbiológica. El PNEC mostró altos contenidos de lípidos y fibra (51.4 y 21.6 g/100g, respectivamente) con buenas capacidades de absorción de agua y aceite. El almacenamiento bajo vacío a 10ºC preservó la capacidad antioxidante (TBARS: malondialdehído, MDA = 0.23 mg/kg, IC50 DPPH = 9.0 mg/mL, y IC50 ABTS = 21 mg/mL luego de un año de almacenamiento). Los recuentos de hongos y levaduras fueron extremadamente bajos en los tratamientos con vacío y envases de baja permeabilidad, para ambas temperaturas. Por lo tanto, el PNE pudo retener adecuados atributos de calidad hasta 12 meses empleando la adecuada combinación de envase y temperatura.
