The total numbers of bacterial populations at 0, 24, 48, 72 and 96 h of fermentation were checked for each sample during the fermentation period. L. Family - Arecaceae.. Common Names(s) - Date Palm. The life span of seeds which may vary from few weeks to many years depends upon (i) species and (ii) the environmental conditions pre­vailing during seeds storage. My advice for dactylifera germination is to keep them warm. It is often dried and eaten raw or used as food sweetener. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. The three samples, each was containing 30 ml distilled water, different date seeds substrate (DFC, FGDSP or AEDSP), at the same quantity was identified from the first fermentation assay. Mandalari, G., NuenoPalop, C., Tuohy, K., Gibson, G. R., Bennett, R. N., Waldron, K. W., Bisignano, G., Narbad, A., Faulds, C. B. Menne, E., Guggenbuhl, N. Fn-type chicory inulin hydrolysate has a prebiotic effect in humans. The highest rate of growth was observed in MRS-Oxoid, then in the MRS-C + 0.6g FGDSP with less growth being observed in MRS-C +0.15g, then FGDSP MRS-C + 0.06g FGDSP. Date seeds are also called kernels, pits, stones or pips. Seeds of Cassia bicapsularis and C. multijuga had been found to remain viable even after 100 years. 1. However, the oldest 14 C-dated seed that has grown into a viable plant was Judean date palm (a cultivar of Phoenix dactylifera) seed about 2000 years old, recovered from excavations at Herod the Great’s palace at Masada in Israel. Gum obtained from the tree is used to treat diarrhea. The seeds were dried at the room temperature. Our mission is to provide an online platform to help students to share notes in Biology. Due to functional properties, date seed can be used for different food and health applications. The medium was also prepared in the laboratory in its modified form which did not contain a carbon source so that it could be supplemented with the date seed products e.g. The second oldest viable 14C-dated recorded seed is now about 1300 years old sacred lotus (Nelumbo nucifera) seed, recovered from a dry lakebed in north eastern China in 1995 (Shen-Miller et al, 1995). The date is composed of a fleshy pericarp and a seed. Probiotics are defined as “live microorganisms which when administered in adequate amounts confer a health benefit on the host”(FAO/WHO 2002). Share Your PDF File The kernels were soaked in distilled water, washed to remove any adhering date flesh, and then dried at 50 °C for two days before being finely ground to1.0 mm in a heavy-duty grinder (Buhler-Miag laboratory disc mill; model DLFU). (2) and Wang, (3) the scientific criteria that must be met for functional food ingredients to be recognized and classified as prebiotics are that they (i) are able to escape digestion in the upper GIT and not absorbed (ii) are fermented by the intestinal microflora (iii) are a selective substrate that changes colonic bacteria composition by stimulating the growth of beneficial colon bacteria such as LactobacilliorBifidobacteriaspp, and inhibiting the growth of pathogenic bacteria like Enterobacteriaceaeand Clostridium spp. These colonies were representative of all the colonies and displayed the general features of LAB. Secondly, to provide some data in relation to their potential use in functional foods that may serve as basic preliminary data in further studies. Share Your Word File a Drinking yoghurt. Hence, in general, reducing the pH values in this study was evidence to indicate that DFC from date seeds may be used as prebiotic. Besbes, S., Blecker, C., Deroanne, C., Drira, N. E., Attia, H. Date seeds: chemical composition and characteristic profiles of the lipid fraction. The ability of R dactylifera to thrive in hot, dry conditions with little or no rain, as long as there is constant moisture about the roots for healthy growth and seed germination, have made it the classic symbol of the oasis. The longest-lived example of a viable seed of known age is the date palm, Phoenix dactylifera L., of which an estimated 2000-year-old seed was germinated in 2005. The date derivatives are rich in nutraceuticals and phytochemicals. What is a mushroom shaped gland? 1 ml was taken from that culture and used to inoculate 10 ml of fresh MRS- Oxoid medium. It was successfully sprouted in 2005 (Sallon et al, 2008). Pick out and discard any seeds that float to the surface because they are probably not viable. Introduction. The inoculum culture was prepared by inoculating MRS medium and incubating it overnight. The total viable count of the yoghurt was 1.21×107 CFU/ ml. The fruits are edible. Thus, as DFC was utilized by the probiotic cultures, it may act as a prebiotic.
