“…In a study by Wei et al (2012), cold pressed rapeseed oil samples were analyzed for volatile compounds to observe the effects of seed variety and different processing operations. It was found that thermal treatment and microwave radiation have significantly changed the aromatic profile of the samples.…”

SUMMARY:The sensory descriptions, aromatic profiles and consumer preferences of poppy seed oils produced from three poppy varieties (ofis3, ofis4, and ofis8) by cold pressing were studied. Roasting and enzyme treatments were applied to the seeds prior to cold pressing. In addition, 75 different volatiles were quantified by GC-MS analysis. A flavor profile analysis was made with 9 panelists and 12 terms were identified for the description of the oil. The results shown that, only earthy term scores were different among the seed varieties, while treatments have caused differences in roasted, hazelnut, hay and sweet aromatic terms. Roasting and enzyme treatments decreased hay and increased sweet aromatic values. The enzyme treatment of the poppy seeds enhanced fermented and waxy scores in the cold press oils. 1-hexanol, 2-heptanone, 2-pentanone, 2-pentyl furan, 3-ethyl-2-methyl 1,3-hexadiene, 2-(dimethylamino)-3-phenylbenzo[b]thiophene, 3-octen-2-one, 4-hydroxyphenylacetic acid, alpha-pinene, limonene, dimethyl sulfone, mercaptoacetic acid, hexanal and nonanal were quantified as the major volatiles in all treatment groups. Consumer test results indicated that roasted samples are more liked, and the yellow (ofis4) roasted sample was identified as the most preferred (53.55%) oil by consumers. This study provides the first sensory descriptive definitions and consumer preferences for poppy seed oils. KEYWORDS:Cold Press; Consumer Acceptance; Flavor Profile Analysis; Poppy seed Oil; Roasting; Volatiles RESUMEN: Aceites de semillas de amapola prensados en frio: Propiedades sensoriales, perfiles aromáticos y preferencias del consumidor. En este trabajo, se analizan las descripciones sensoriales, perfiles aromáticos y preferencias de los consumidores de aceites de semillas de amapola producidosmediante prensado en frío a partir de tres variedades (ofis3, ofis4, y ofis8).Previo al prensado en frío, a las semillas se aplicóuna fase de tostado y un tratamiento enzimático. Además del análisis GC-MS donde se cuantificaron 75 compuestos volátiles, el perfil del sabor,realizado con 9 panelistas,logra identificar 12 términos descriptores. Los resultados muestran que, solamente la puntuación del término "terroso" fue diferente entre las variedades de semillas, también los tratamientos provocan diferencias en los términos, tostado, avellana, heno y aromas dulces. El tostado y los tratamientos enzimáticos disminuyeron la puntuación de heno y aumentó los valores de aromático dulce. El tratamiento enzimático de las semillas de amapola mejora los valores de fermentado y cera en los aceites prensados en frío. Los principales compuestos volátiles cuantificados en todos los grupos y tratamientos fueron:1-hexanol, 2-heptanona , 2-pentanona, furano 2-pentilo, 3-etil-2-metil 1,3-hexadieno, 2-(dimetilamino)-3-fenilbenzo[b]-tiofeno, 3-octen-2-one, ácido 4-hidroxifenilacético, alfa-pineno, limoneno, dimetilsulfona, ácido mercaptoacé-tico, hexanal y nonanal. Los resultados de las pruebas de consumo indican que las muestras tostadas son las que más...

“…Solvent extraction is more efficient in terms of quantity of oil produced compared to mechanical pressing. However, negative drawbacks using solvent extraction consist of longer and more expensive processing, production of hazardous waste, and alteration of end quality output (Buenrostro & López-Munguia 1986;Wei et al 2012). Fatty acid composition impacts several characteristics of biodiesel quality such as: flashpoint, viscosity, cetane number, cloud point, pour point, calorific value, acid value, ash content, and cold flow properties.…”

This study explores canola production in the south eastern United States in order to successfully adapt to the market demand for high valued oilseeds. Two primary objectives were established, determining yield response, and oil quality of harvested seed. Two canola cultivars were evaluated for production in a Piedmont soil (Mecklenburg Sandy Clay Loam) at NC A&T State University research farm located in Greensboro, NC (Guilford County). The study was conducted using a split-plot design with the main plot factor cultivar (Virginia and DKW 46-15), and subplot factor fertilizer rate: (N-P2O5-K2O) in (kg/ha) 0-0-0 (T1), 70-28-84 + Soysoap (T2), 140-56-168 (T3) and 140-56-168+Soysoap (T4). Canola oil was extracted using a soxhlet apparatus. For both seed and oil yield response, the effects of fertilizer treatment and cultivar were significant influences. Seed and oil yield response was statistically higher for DKW 46-15 compared to the Virginia cultivar. Application of treatment T4 will maximize oil and seed yield compared to treatments T2 & T1 fertilizer treatments. Higher erucic fatty acid concentrations were found in oil originating from Virginia seeds compared to DKW 46-15. Based on yield response and fatty acid composition, DKW 46-15 might better serve the bio-material feedstock supply chain compared to the Virginia cultivar when produced in the piedmont region of North Carolina.
