Sensory Metabolite Profiling in a Date Pit Based Coffee Substitute and in Response to Roasting as Analyzed via Mass Spectrometry Based Metabolomics

Interest in developing coffee substitutes is on the rise, to minimizing its health side effects. In the Middle East, date palm (Phoenix dactylifera L.) pits are often used as a coffee substitute post roasting. In this study, commercially-roasted date pit products, along with unroasted and home-prepared roasted date pits, were subjected to analyses for their metabolite composition, and neuropharmacological evaluation in mice. Headspace SPME-GCMS and GCMS post silylation were employed for characterizing its volatile and non-volatile metabolite profile. For comparison to roasted coffee, coffee product was also included. There is evidence that some commercial date pit products appear to contain undeclared additives. SPME headspace analysis revealed the abundance of furans, pyrans, terpenoids and sulfur compounds in roasted date pits, whereas pyrroles and caffeine were absent. GCMS-post silylation employed for primary metabolite profiling revealed fatty acids’ enrichment in roasted pits versus sugars’ abundance in coffee. Biological investigations affirmed that date pit showed safer margin than coffee from its LD50, albeit it exhibits no CNS stimulant properties. This study provides the first insight into the roasting impact on the date pit through its metabolome and its neuropharmacological aspects to rationalize its use as a coffee substitute.

Date Pits

In this study date pits of two types of date-palm trees (Phoenix Dactylifera L.), in Saudi Arabia were used as bio-sorbents for heavy metals (e.g. lead and copper) from aqueous solutions. Investigation of equilibrium time and the effect of different concentrations of metals were performed. Adsorption capacity of bio-sorbents increased when increasing concentration of metal ions. Maximum adsorption capacity at room temperature of Sukary date pits was 17.53 mg g-1 and 9.86 mg g-1 for lead and copper ions, respectively. Whereas, Khlass date pits showed maximum adsorption capacity at 14.1 mg g-1 and 7.91 mg g-1 for lead and copper ions, respectively at room temperature. Equilibrium isotherm models, (Langmuir and Freundlich models), were used for analysis of equilibrium experimental results. these models describe the experimental data well.

The biochemical composition, secondary metabolites (phenolic compounds, flavonoids) and antimicrobial potential of different varieties of Emirati date (Phoenix dactylifera L.) pits were investigated. Total phenolic acids (TPC) and total flavonoid contents (TFC) of the different date pits were measured using a Folin–Ciocalteau reagent. Different organic solvents [(n-hexane; H2O: EtOH (1:1); ethyl acetate; acetone: Water (1:1); and methanol: Chloroform (1:1)] were compared to evaluate the phytotoxicity of Ajwa, Fard, Khalas, Khodari, Abu Maan, Lulu, and Mabroom date pits. The antimicrobial activity of the date pit extracts were evaluated by means of agar-well diffusion assay on Staphylococcus aureus (ATCC 29123), Escherichia coli (ATCC 25922) and Candida albicans (ATCC 66027). Minimum inhibitory concentrations (MICs) were measured following clinical laboratory standardization institute (CLSI) protocol. The biochemical analyses of date pits indicate that TPC were ranged from 7.80 mg of equivalent gallic acid⁄100 g dry weight in Ajwa to 4.65 mg in Mabroom. The TFC were ranged between 1.6–4.54 mg of equivalent catechin⁄100 g dry weight. Ajwa pit extract showed good quality traits (higher protein, lower ash content, and intermediate dietary fiber). The results indicate that the ethyl acetate extract of Khalas and Khodari inhibited S. aureus with an inhibition zone diameter of 20 mm and MIC of 10 mg/mL. Abu Mann pit extract inhibited the S. aureus and also decreased the population of E. coli. The diameter of inhibition zone was 15, 16, and 18 mm after treatment with Ajwa extracts, while the MICs were 7.5 and 5 mg/mL. The MeOH: CFM extract of Abu Mann and Ajwa was more potent against E. coli bacteria than any other extract. This work demonstrates that the Emirati date pits extract has antimicrobial (antibacterial, antifungal) potential and can be used as phytotoxic natural compounds.

Date Pits

Background: Date palm (Phoenix dactylifera L.) is a dominant fruit crop in most of the Arabian countries. Date pits, as a major byproduct which remained after consumption of date flesh proved to be valuable source of energy. Methods: Solid State Degradation (SSD) system was used for the preparation of degraded date pits. Date pits degraded with Trichoderma reesei were evaluated for their proximate, chemical composition and antioxidant activity. Results: The crude fiber content of degraded date pits was found to be 20.8 %, ash (2.09%), crude fat (7.2%), protein (5.56%), and total carbohydrate (87.2%). Neutral detergent fiber (NDF) and acid detergent fiber (ADF) was found to be 74.6% and 45.7%, respectively. Monosaccharide composition of fiber showed that the degradation with T. reesei significantly (P<0.05) enhanced the glucose and mannose content of cellulose, hemicellulose and lignin. Pectin, total carbohydrate and mannan oligosaccharide content were also increased in degraded date pits in which galactose and mannose were the major neutral sugars. Among the studied minerals, potassium, calcium, magnesium, sulphur and phosphorus were predominant. The phenolic and flavonoid contents of degraded date pits significantly (P<0.05) increased to 14.230 g Gallic equivalent/100g DW and 11.68 g Rutin equivalent /100g DW. Degraded date pits also showed significant antioxidant activity as evidenced by the results of 2,2-diphenyl-1- picrylhydrazyl(DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline 6 sulphonicacid) (ABTS) and Ferric Reducing Antioxidant Power (FRAP) assays. Conclusion: Biological degradation with T. reesei significantly (P<0.05) improved the nutritional effect of date pits and thereby its potential usage in food industry was greatly improved.

Date Pits

A new ingredient from date palm coproducts (pits) was obtained and tested as a preservative in burgers. Different concentrations of date pit (0%, 1.5%, 3%, and 6%) were added to beef burgers, and its effect on the safety and quality was evaluated during 10 days of storage. The incorporation of date pit was able to improve the shelf life and the cooking properties of the burgers. The date pit stabilized the color, lipid oxidation, and microbial growth of the burgers during the storage time due to the antioxidant activity and the phytochemical content of the date pits. For the consumer panel, the color and the off-odors were improved, and the addition of 1.5% and 3% date pit in cooked burgers obtained similar scores. Based on the obtained results, the new ingredient from date pit may have potential preservative properties for enhancing stability during shelf life and could improve the composition of bioactive compounds (fiber and phenolic content) of beef burgers.

Nutritional Benefits

The use of coffee as a beverage is a widespread practice all over the world. However, the adverse effects of caffeine is a challenge for consumers, hence the need for development of coffee substitutes. This study explored the proximate, free-radical scavenging (DPPH) and sensory properties of coffee substitute developed from seeds of Adansonia digitata L. and Phoenix dactylifera L. Seeds were processed into coffee through drying, roasting and milling. Analytical procedures were carried out following standard procedures. Sensory properties of the two coffee substitutes were compared to that of a commercial coffee. Baobab coffee had significantly higher (p<0.05) ash, protein, fat, fiber and carbohydrate content than those from date palm seeds. While the normal coffee scored higher in aroma and flavor compared to the coffee substitutes, the overall acceptability of baobab coffee was comparable to that of normal coffee. In conclusion, these coffee substitute have nutritional benefits and are acceptable by consumers. However, further technological developments are required to improve the aroma and flavor to a level comparable to that true coffee.
