Characterization of the seed oil and meal from apricot, cherry, nectarine, peach and plum

Abstract

The oil and meal from apricot, cherry, nectarine, peach and plum seeds were characterized for their physico-chemical properties. The wt% seed/fruit ranged from 2.8-7.6% and the wt% kernel/seed ranged from 6.8-31.6%. Kernel moisture ranged from 38.8-72.4%. The proximate composition of whole seeds on a dry weight basis ranged from 1.3-6.9% protein, 0.6-14.5% fat, 51.0-72.3% fiber, 0.4-1.2% ash, and 18.1-27.9% carbohydrate (by difference). The kernels contained 41.9-49.3% fat, and the resulting meals contained 31.7-38.7% protein. The major fatty acids were oleic (52.9-66.3%) and iinoleic (26.8%-35.0%). The major essential amino acids were arginine (21.7-30.5 mmoles/100 g meal) and leucine (16.2-21.6), and the predominant nonessential amino acid was glutamic acid (49.9-68.0). The iodine values ranged from 105 to 113, hydroxyl value from 5.5 to 7.0 and the unsaponifiables from 0.56-0.80%. The mineral composition (Cu, Fe, Ca, Mg, Zn, P) was also determined on the meals.

Properties of Apricot Kernel and Oils as Fruit Juice Processing Waste

“…These properties are effected mainly by variety [16]. However, higher protein contents (37-45 g/100g) have been reported by several authors [6,16]. The results in this work are in general agreement with these results.…”

“…This not only wastes a potentially valuable resource but also aggravates an already serious disposal problem. To be economically viable, however, both oil and meal from these fruits seeds must be utilized [6].…”

Chemical characterization and thermal properties of kernel oils from Tunisian peach and nectarine varieties of <em>Prunus persica</em>

“…In both locations, the peach kernels exhibited the highest levels of oil content. As shown in Table 1, these results are within the values previously reported in the literature for the oil content of peach and nectarine dried kernels, ranging from 42.2% in Canadian fruits (Kamel and Kakuda, 1992) to 54.5% in Egyptian fruits (Rahma and Abd El-Aal, 1988). Furthermore, the oil contents were comparable with those of other oil crops of commercial interest, such as sunflower and rapeseed.…”

Cryopreservation of dormant orthodox seeds of forest trees: mazzard cherry (Prunus avium L.)

“…A large proportion of storage materials accumulated in mazzard cherry seeds (45%) are lipids (Kamel and Kakuda, 1992) in the form of triglycerides (Bernardo-Gil et al, 2001). Seeds of Cuphea carthagenesis [a mazzard herb found in Mexico and Central and South America (Graham, 1988)], classified as suborthodox (intermediate), contain large amounts of storage lipids, very much like mazzard cherry seeds, and they lose the ability to germinate during storage at 5 • C at high w.c. levels (< 5%) (Crane et al, 2006).…”
