“…Grosso and Guzmán, (1995) studied local peanut cultivars in Peru and reported an oleic/linoleic ratio of 1.2. The oleic/linoleic ratio in oil depends on several factors: type of soil; high precipitation and sandy soils promote a high ratio (Grosso et al, 1994;Holaday and Pearson, 1974), soil and air temperature; the higher, the better (Golombek et al, 1995;Casini et al, 2003). precipitation and high temperatures) described as favorable factors to increase the oleic/linoleic ratio are typical conditions in Veracruz, Mexico, where the present study was carried out.…”

“…Peanuts (Arachis hypogaea L.) contain various oleic/linoleic ratios (Venkatachalam and Sathe, 2006;Isleib et al, 2006). This quality is affected by cultivar location (Grosso et al, 1994), soil temperature (Golombek et al, 1995), atmospheric temperature, and amount of rain (Casini et al, 2003). Recently, several attempts have been made to produce new cultivars with improved nutritional qualities such as chemical composition, phytochemicals and high oleic/linoleic ratios (Jonnala et al, 2005a).…”

RESUMEN Composición nutricional de nuevas variedades de cacahuate (Arachis Hypogaea L.)Se estudio el rendimiento agrícola y composición quími-ca (proteína, grasa, carbohidratos, fibra y cenizas), perfil de amino ácidos, digestibilidad, perfil de ácidos grasos, contenido de tocoferol y de esteroles de seis variedades de cacahuate (Arachis hypogaea L.) Col-24-Gro, Col-61-Gto, VA-81-B, Ranferi Díaz, NC-2 y Florunner. Los resultados mostraron que el mayor rendimiento se logró en las variedades Ranferi Díaz y Col-61-Gto (6.3 Ton/ha). El contenido de proteína fue de 23.5 a 26.6% y el contenido de grasa en un intervalo de 49.8 a 53.4%. La digestibilidad promedio de las seis variedades fue de 86%. El contenido de lisina y treonina en la proteína de todas las variedades fue suficiente para satisfacer los requerimientos del humano. La composición del aceite de las diferentes variedades de cacahuate se caracterizó por contener de 15-18% de ácidos grasos saturados. La relación oleico/linoleico fue de 1.3-1.4. El contenido de tocoferoles totales fue entre 390 a 706 ppm. El mayor contenido de tocoferol correspondió a las variedades con los rendimientos más bajos. Con respecto al contenido de alfa tocoferol se encontró entre 90-150 ppm y el gamma tocoferol fue entre 270-570 ppm. El contenido de β-sitosterol fue similar en las seis variedades (aprox. 65%). La variedad Ranferi Diaz presentó el más alto rendimiento agronómico y el más alto contenido de proteína. Sin embargo, esta variedad presento el más bajo contenido de ácido oleico, bajo contenido de esteroles y bajo contenido de tocoferoles totales. Estas diferencias entre las variedades de cacahuate sugieren que cada una de ellas deberá tener diferente uso como alimento.

SUMMARY Nutritional composition of new Peanut (Arachis hypogaea L.) cultivarsSix peanut (Arachis hypogaea L.) cultivars (Col-24-Gro, Col-61-Gto, VA-81-B, Ranferi Díaz, NC-2 and Florunner) were studied for agricultural yield, chemical composition (protein, fat, carbohydrates, fiber and ash), amino acid profile, digestibility, fatty acid profile, tocopherol and sterol contents. Results indicated that Ranferi Díaz and Col-61-Gto presented the highest yield (6.3 Ton/ha). Protein content was from 23.5 to 26.6% and fat content ranged from 49.8-53.4%. Mean digestibility was 86%. Lysine and threonine levels in all cultivars were sufficient to meet human requirements. Total saturated fatty acids ranged from 15-18%. The oleic/linoleic ratio was estimated 1.3-1.4. Tocopherol levels varied from 390 to 706 ppm. The highest tocopherol levels corresponded to the cultivars with the lowest yield. The alpha tocopherol content was estimated at 90-150 ppm, while gamma tocopherol was 270-570 ppm. The main sterol present was β-sitosterol (approx. 65%). Ranferi Diaz variety presented the highest agronomic yield and the highest protein content but low oleic acid, low sterols and low total tocopherols. The differences among c...

Effect of separate pod and root zone temperatures on yield and seed composition of three Spanish cultivars of groundnut (Arachis hypogaea L)

The effect of separate pod and root temperature regimes (all four combinations of 28/22 and 40/34°C day/night temperature), imposed from the time of peg penetration until harvest, on yield and seed composition of three Spanish genotypes of groundnut (Arachis hypogaea L) was investigated. A decrease in pod temperature from 40/34 to 28/22°C increased yield and oil, starch and protein mass per plant irrespective of root temperature. Additionally, a reduction in pod temperature decreased protein concentration and increased the sum of oil and starch concentration at a root temperature of 28/22°C, whereas at a root temperature of 40/34°C a decrease in pod temperature increased protein concentration. Root temperature reduction diminished oil concentration of genotypes AH 6179 and TMV 2 at a pod temperature of 40/34°C. A decline in pod temperature affected fatty acid composition through a decrease in palmitic acid irrespective of root temperature and an increase in linoleic acid at a root temperature of 28/22°C. A root temperature effect on fatty acid composition was not detected. It is concluded that ®eld management practices and choice of genotype can in¯uence groundnut yield and seed composition through effects on pod and root temperature.

Cactus pear fruit seeds contain oil that can be utilized for human consumption. Forty‐two South African cultivars are evaluated over two seasons for seed oil content and fatty acid composition in an attempt to ascertain the best oil yielding cultivar. Seed oil content varied among cultivars and seasons and the yield ranged between 4.09 and 8.76% of seed mass. The unsaturated fatty acids are the most prominent and were dominated by linoleic acid, which varied between 56.86 and 65.21%, followed by oleic acid (16.44 and 22.51%), while the saturated fatty acids palmitic and stearic acid content ranged from 12.72 to 16.05% and from 2.21 to 3.39%, respectively. Cultivar and variation in rainfall have a statistically significant effect on cactus pear seed oil content and fatty acid composition. Principal Component Analysis show that certain cultivars are exclusively associated with specific characteristics. This is the most comprehensive study of the seed oil characteristics of the available cultivars in South Africa ever to be performed. The American Giant cultivar have the highest seed oil yield. Practical Applications: In a semi‐arid country such as South Africa, the value of by‐products and waste products from a drought resistant plant such as cactus pear should be emphasized. Cactus pear seed oil is a novel and expensive essential oil. The emergence of many small‐holding farms and small‐scale processing facilities necessitated a comprehensive investigation into the oil composition of all the available cactus pear cultivars. Essential knowledge regarding cultivar choice in terms of oil‐production and specific fatty acid composition, as well as seasonal effects thereon, is generated with this research. This research indicats that the American Giant (Opuntia ficus‐indica) cultivar have the highest oil yield wheras the Roly Poly cultivar have the highest linoleic acid content. This data will enable processors to make recommendations to producers to use cultivars with optimum yield and oil quality as production target. Cactus pear fruit seeds contain oil that can be utilized for human consumption. Forty‐two South African cultivars are evaluated over two seasons for seed oil content and fatty acid composition in an attempt to ascertain the best oil yielding cultivar.
