RAYA-PEREZ, J.C. et al. Storage proteins characterization and mineral composition of black cherry seed (Prunus serotina). Polibotánica [online]. 2012, n.34, pp.223-235. ISSN 1405-2768.

Black cherry kernels is greatly appreciated and consumed in central Mexico. This seed represents a valuable resource from the economic point of view and nutrition as it has a good content of protein and oil. Despite being known for the amygdalin production of these seeds, people of the region consume it without any problems of intoxication. Storage proteins characterization indicates that it has a high content of albumin. Protein solubility is better shown at pH values 6, 7 and 12. The elemental composition presents levels similar to other seed components such as sulfur (0.11%), phosphorus (0.17%), calcium (0.07%), magnesium (0.13%), potassium (0.68%) and sodium (0.10%); the almond shown a high lipid content (almonds from Mexico city 38%, from Uruapan 45%, from Tarascan Plateau 41.5%) and also shows 28% in protein content. Preliminary studies show differences between the seeds are consumed (central Mexico) and where they are not exploited (Uruapan, Tarascan upland). A further characterization could enable wider use and use in regions where there is now wasted.
