Abstract
The chemical composition of the seed shell of the apricot (Prunus armeniaca) were investigated. Acid and neutral detergent fibres (ADF and NDF) and their fractions—hemicellulose, cellulose and lignin—were determined. The NDF content was about 920 g kg−1 DM. The concentrations of oils, soluble sugars, pectins, polyphenolic compounds, proteins and mineral elements were also determined. None of these fractions was present at levels higher than 25 g kg−1 DM. Essential amino acids comprised 38‐41% of the total amino acids. Potassium (2.44 g kg−1) was the most abundant element, followed by calcium (1.15 g kg−1). Some possible applications for apricot seed shell are considered.
