Chemical Composition of Garden Cress (Lepidium sativum) Seeds and Its Fractions and use of Bran as a Functional Ingredient

“…Andersson et al [18] reported 19% protein, 20% crude fat and 40% dietary fibre in L. campestre. Like in L. sativum in the present study, insoluble dietary fibre dominated in L. campestre and rapeseed and consisted mainly of Klason lignin, a phenolic constitutent mostly found in the husk of seeds [9,19]. When seeds of L. sativum were soaked in water a large transparent gel was formed surrounding the whole seed.…”

“…Three fractions namely the whole meal, bran and endosperm were analysed for chemical composition using standard AOAC procedures [9]. Minerals were determined using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICPAES, Leeman Labs Plasma Spec Z.5, Lowel, MA) [10] in ash solution of the samples prepared as per AOAC procedure [9].…”

“…The extract is saponified with ethanolic potassium hydroxide and fatty acid methyl esters (FAMEs) were formed by reaction with boron trifluoride/methanol [9]. The FAMEs were quantitatively measured using the gas chromatograph (Hewlett Packard 6890 GC with FID detector) fitted with Supelco 2560 column (100 M × 0.25 mm id, 0.2 µm film thickness) operated in constant pressure mode at 75 PSI helium.…”

“…sativum seeds possessing number of pharmacological properties [6], can be a functional food ingredient about which there are no studies even though there are few studies on its phytochemistry [7,8]. Also there are no studies on the composition of its different fractions-bran and endosperm, the study on which may help to identify the fraction for a particular use depending on its composition even though there are few studies on composition of the seed as a whole [3] and on Lepidium campestre, a member of the same family of Lepidium sativum [9]. So the present study was conducted to analyse the bran and endosperm fractions of garden cress seeds for their chemical composition, mineral contents, protein, amino acid and fatty acid profiles as a preliminary work to explore the possibility of using this as a functional ingredient in product formulations.…”
