Influence of Utilization of Natural Waste Fibers Pyrolysis on Mechanical Properties and Microstructure of Concrete

ABSTRACT The main purpose of this paper is to investigate the impact of the thermal processing of natural fibers on the strength of what is considered fiber-reinforced concrete. Natural fibers extracted from palm trees and bamboo residues were collected and pyrolyzed. The investigation of the morphological alterations that occur during the pyrolysis of natural fibers at a temperature of 200°C showed the impact of the cementitious environment on this process. In addition, the mechanical characteristics of fiber-reinforced concrete were conducted on different dosages (1, 1.5, 2, and 5% wt.) of treated and untreated palm oil, date kernel, and bamboo fibers. The results demonstrated that the inclusion of fibers up to 1.5% wt. enhanced the concrete mixes mechanical properties, which included pyrolyzed fibers. Analyzes of the concrete microstructure revealed that the treated fibers were not damaged. The 1.5% wt. addition of fibers after pyrolysis process can effectively improve their adhesion to the matrix and reduce the width and number of cracks. The analysis of variance results for flexural strength indicated that all sources had no significant impact on the flexural strength of untreated or pyrolysis treated natural fiber reinforced concrete.

Natural variability in yield and properties of Balanites aegyptiaca (L.) Delile kernel oil from different locations in Nigeria

Balanites aegyptiaca known as the desert date is an underutilized and neglected wild fruit tree/shrub of the arid and semi-arid zones with high economic potential. This study, therefore, was conducted to investigate the yield, physico-chemical and phytochemical properties, proximate and mineral composition of desert date kernel oil from different locations. Oil was extracted using the soxhlet apparatus, while hexane served as solvent. Standard procedures were used to determine the yield and properties of desert date kernel oil. The data obtained were subjected to the analysis of variance (p< 0.05). Oil yield (%) was found to range from 21.09±1.04-43.95±1.85 and varied significantly among the locations. Acid and saponification values (mg KOH/g) increased significantly from 2.11±0.07 to 1.36±0.07 and 76.35±0.22 to 179.85±0.90, respectively. The refractive index ranged from 1.36±0.15 to 1.48±0.06, while the iodine value (mg KOH/g) varied significantly from 67.07±1.53 to 85.33±2.52. Saponins, tannins, and phenol were discovered to vary significantly among the locations, and range from 3.82±0.30 -5.83±0.45 (mg/100 g), 1.31±0.10 - 1.68±0.03 (mg/100 g) and 1.51±0.05 - 2.09±0.06 (mg/100 g), respectively. The broad variability observed in the properties of desert date kernel oil among locations indicates the feasibility of improving kernel oil yield and properties through selection

Date kernel biochar: A green approach to methylene blue removal from polluted water in Iraq

ABSTRACT This study investigated the potential use of biochar produced from Iraqi date kernels (Khestawi) as an adsorbent for methylene blue (MB) removal from polluted water. A full factorial design methodology was employed to examine the effects of heating rate, pyrolysis temperature and holding time on the performance of the produced biochar. The results showed that pyrolysis temperature and time had a strong effect on the biochar performance, while the heating rate had a weaker effect. The biochar produced at pyrolysis temperatures of 350°C and 550°C exhibited MB removal percentages (% R) of 48.9% and 30.9%, respectively. Similarly, biochar production through pyrolysis durations of 30 and 90 minutes resulted in MB removal rates of 47.5% and 30.3%, respectively. The adsorption experimental data was well-fitted by the Freundlich isotherm model, with a high value of the Freundlich constant (KF = 1.64), indicating a high adsorption capacity of the biochar. The activation of biochar using bio-oil (organic-1) led to a substantial enhancement in the adsorption capacity, with the activated biochar (ABC-1) exhibiting a higher adsorption capability and a higher value of the Freundlich constant (KF = 7.12). Overall, the results suggest that biochar produced from date kernels has the potential as an effective and sustainable adsorbent for MB removal from polluted water, with the potential for further enhancement through biochar activation.

The effect of date (Phoenix dactylifera L.) varieties on bioactive compounds, phenolic constituents, fatty acids and element contents of date seed and oils

AbstractIn this study, the oil amounts, bioactive components, fatty acid profiles and element quantities of the date kernels (Osailah, Rothanh Qassim, Rushudiah, Nabtat‐Ali, Sbakah) were determined. The oil quantities of the date seeds were altered to be between 3.50 (Osailah) and 5.55% (Nabtat‐Ali). The total phenolic quantities of the seeds were assigned to be between 330.83 (Rothanh Qassim) to 365.42 mg GAE/100 g (Osailah) while antioxidant activities of date seeds are assessed to be between 13.89 (Rothanh Qassim) and 38.74% (Nabtat‐Ali). The total flavonoid quantities of the date seeds were displayed to be between 4824.83 (Osailah) and 9133.17 mg/100 g (Sbakah). The (+)‐ Catechin and 1,2‐dihydroxy benzene quantities of the date seeds were established to be between 75.01 (Rothanh Qassim) and 186.02 mg/100 g (Sbakah) to 67.43 (Rothanh Qassim) and 199.89 mg/100 g (Sbakah), respectively. Oleic acid amounts of the seed oils were altered to be between 45.89 (Rothanh Qassim) and 52.55% (Nabtat‐Ali). K, P, S, Ca and Mg were the key minerals of the date seeds. Considering the bioactive components, polyphenol contents, fatty acid composition and mineral content of date kernels, it is thought that date kernel powders can be added to some foods as a food supplement.

Suitability of dyes from cinnamon bark on wool fibers using metal and bio-mordants.

Growing concern about the environmental effects of metal mordants and synthetic dyes is encouraging the use of bio-mordants and natural colorants. Cinnamon bark is a rich source of natural colorants such as cinnamaldehyde and tannins. The main purpose of this research was to study and compare the effect of bio-mordants versus metal mordants in terms of colorimetric parameters and color fastness properties of cinnamon bark on wool fibers. Accordingly, some bio-mordants, including date kernel, peppermint, banana peel, and artemisia, as well as some metal mordants like aluminum potassium sulphate and copper sulphate, were studied based on three conventional mordanting methods (pre-, meta-, and post-mordanting). The results indicated that the conjunction of metal mordants and polyphenolic bio-mordants with cinnamon colorants can create different hues and tones of brown. Also, the color produced by cinnamon in wool fibers has poor color fastness and low color strength. Overall, bio-mordants have presented good color properties, making the dyeing process eco-friendly and greener. Among the applied bio-mordants, peppermint has created the best color strength and color fastness.

The Impact Of Partial Substitution Of Date Palm Kernel Powder As An Alternative Energy Source For Grains In The Diet On The Productive Performance Of Broiler Chickens.

In this study, 160 unsexed day-old Cobb broiler chicks were utilized to investigate the impact of incorporating various levels of date palm kernel powder into broiler chicken diets on productive performance. The chicks were raised in a closed poultry barn in Ain Zara, Tripoli, Libya, from September 10, 2022, to October 23, 2022, using a floor-rearing system. The study comprised four different dietary treatments, in addition to a control treatment, with chicks randomly and replicatively distributed. Each treatment consisted of four replications, and each replication included ten chicks. Date palm kernel powder was added at levels of 0%, 3%, 5%, and 7% to the first (control), second, third, and fourth treatments, respectively, during the starter and grower phases. The experimental treatments were uniform in nitrogen (23%) and caloric content (3200 kcal/kg). A free-choice feeding system was implemented, providing feed and water to the chicks throughout the six-week study period, with temperature monitoring. The chicks were raised under consistent environmental conditions, including lighting, ventilation, bedding, labor, and a comprehensive therapeutic, preventive, and vaccination program throughout the experimental period. The study also encompassed evaluating average weight gain, feed consumption, feed conversion ratio, and mortality rate for 42-day-old birds. Results demonstrated a significant (P≤0.05) effect of adding date palm kernel powder to broiler chicken diets on weight gain and feed efficiency compared to the control treatment. Sequential addition of date palm kernel powder at levels of 3%, 5%, and 7% led to improvements in weight gain and feed efficiency. Additionally, higher levels of addition resulted in enhanced weight gain and feed efficiency, with the optimal weight gain observed at the 7% addition level, followed by the 5% addition level, and then the 3% addition level, in comparison to the control treatment (0%). Conversely, the best feed efficiency was recorded for the fourth (7%) and third (5%) treatments, respectively, compared to the control treatment (0%). No statistically significant differences were noted in feed consumption and mortality rate among all treatments, as mean values were similar. Based on the results, utilizing date palm kernel as an alternative energy source to grains could be significant, especially in regions where palm trees are cultivated, providing essential grains for human consumption. Keywords: Date kernel, productive performance, broiler, weight gain, feed efficiency.

Investigating the possibility of using date kernel ash as supplementary cementitious material in sustainable concrete

The cultivation of dates from palm trees is an important economic activity in Iraq. Date production forms a significant part of the country's agricultural sector, contributing to both local consumption and export markets. The date industry supports many livelihoods and businesses in Iraq. The total number of fertile palm trees in Iraq is over 22 million. In the production of pitted dates, date molasses, date paste and date confectionery, a significant amount of date pits are usually discarded as waste. This study reports chemical analysis investigations conducted to evaluate the potential use of waste date kernel ash (DKA) compared with other pozzolanic material which is fly ash (FA) from bricks factory, tow samples obtained as a partial cement replacement in concrete, the first sample by the calcination of date pits at 500 °C for 4 hours then cooling and continue calcination at 600 °C for 2 hours, and the second sample by calcination at 500 °C for 4 hours. The results of (XRF) tests showed that DKA has low silica oxide and does not qualify as a pozzolanic material compared with a high silica oxide of FA.

Physicochemical characterization and antioxidant capacity of the extracted oil from date pits and its effect on storage stability of margarine

Background and aims: The present work deals with the valorization of the date kernel oil of Mech-Degla variety by assessment of its physicochemical and antioxidant properties as well as its use in the formulation of margarine. Methods: Kernels’ oil was extracted using Soxhlet method and its total phenolic (TP), flavonoid and carotenoid contents and DPPH• scavenging activity were estimated using colorimetric assays. After that, this oil was incorporated into margarine. The determined physicochemical parameters were the pH, the salt content, the solid content, the melting point, and the peroxide index. Finally, the elaborated margarine's oxidative stability was evaluated by the Rancimat test. Results: The yield of fat in the extracted oil was 9.84 ± 1.45% and the amount of TP, flavonoids and carotenoids were 112.92 ± 26.57 mg gallic acid equivalent /kg of oil, 15.7 ± 0.7 mg quercetin equivalent/kg of oil and 125.534 ± 0.109 mg β-carotene equivalent/kg of oil, respectively. As regards the anti-DPPH effect, the cold and hot date kernel oil extracts exhibited a moderate capacity by reducing 55.91% and 30%of the free radicals, respectively. After that, table enriched margarine has been industrially elaborated at the Cevital agri-food complex by adding 50 and 100 ppm of date kernel oil. Texture of this margarine was plastic and easy to spread, with an acceptable color and a brilliant and homogeneous appearance. At 37 °C, the solid fat content (SFC) index is lower than 6%, which attested that this margarine melts easily in the mouth. The physicochemical characteristics of the formulated product were also assessed and demonstrated that its pH value was 4.2, its peroxide value was 0.32 meq of O2/Kg of margarine and its melting point was 36.0°C. It was also revealed using the rancimat test that the margarine enriched in date kernel oil proved to be more resistant to oxidation, than the control one. Conclusions: Date kernel oil can be used as a natural additive to enrich table margarine without affecting its properties while improving its oxidation stability. Keywords: Date kernels oil, antioxidant activity, margarine formulation, physicochemical characteristics, oxidative stability.

The results indicated a significant improvement when diluting the feed with date kernel powder compared to the control treatment in all the studied productive traits; the dilution of feed with cultivar date kernel powder gave the best results in a significant way compared to the other treatments. Keywords: feeding dilution, date kernels, productive traits, broilers.

Reducing the Salinity of the Produced Water from Oil Field Using Activated Carbon Extracted from Waste Date Kernel

Oil production operations are commonly divided into three periods: "Primary, Secondary and Enhanced Oil Recovery EOR”. Primary recovery is considered as the initial production stage, resulting from the displacement of natural derive mechanisms that exist in a reservoir. Secondly, the secondary recovery period which is the water flooding, or gas injection. The final stage period is EOR period, which involves the injection of external material into a reservoir. Where the injected slug interacts with the reservoir rock or oil system to create favorable conditions in order to enhance the oil recovery.
 The produced water can be used as the water flooding during the secondary recovery, but the high salinity of the formations yields a low recovery factor. Thus, some materials have been used to reduce the water salinity during the production in order to reinject it into the reservoir and cause a high recovery factor. The challenge to obtain an economic material which is able to reduce the salinity in the oil fields is still at stake. Thus, many materials need to be applied in order to test its ability to reduce the water salinity. The activated carbon extracted from waste date kernel have not used yet in this area. In the present paper, the activated carbon was prepared at lab by following specific procedures. Where, a different size of activated carbon extracted from date kernel used to treat the saline water, which later will be used for a spontaneous imbibition test for sandstone core samples after saturated with crude oil. A spontaneous imbibition test consisting of three scenarios of activated carbon at various temperatures and later compared with untreated reservoir water. In this study, the spontaneous imbibition test was performed at room temperature and oven temperature including (45, 55, and 70 ℃). The results showed that activated carbon is a useful material to reduce the water salinity. Where, the best oil recovery was at a treated water with activated carbon volume (0.125), which was (70.41%), that was at the maximum used temperature.

Active and smart antimicrobial food packaging film composed of date palm kernels extract loaded carboxymethyl chitosan and carboxymethyl starch composite for prohibiting foodborne pathogens during fruits preservation

The presented work aims to maximize the benefits of plant waste that does not degrade or decompose quickly and consumes an enormous financial burden for disposal or causes environmental pollution. Therefore, polymeric films of carboxymethyl chitosan (CMCs) and carboxymethyl starch (CMS) containing date kernel (DK) extract were prepared, intending to apply it as a material that can kill microbes that lead to spoilage of preserved fruits. It was noted from the results that DK extract did not affect the morphological structure of the formed films, and there is good compatibility with film polymers. The findings also illustrated that, DK extract aimed to form bonds with both polymers in the presence of the crosslinking agent, which eventually works to create insoluble films in water to a large extent. Results revealed that the CMCs/CMS/DK-3 had superior antimicrobial possibilities against all selected microbes without any hazardous effect while applied to the microbially contaminated solution. The current study recommended such promising edible film as a potential prototype for developing antimicrobial food packaging materials that promote the safety and freshness of fruits and vegetables.

The effect of date seed powder supplementation on glycaemic markers and lipid profile in women with overweight and obesity: a randomised controlled trial

SummaryThis randomised controlled trial aimed to investigate the effect of date kernel on glycaemic control, lipid profile, and weight in women with overweight and obesity. A total of 124 women with overweight or obesity were randomly assigned to receive the date kernel supplement or placebo for 12 weeks. Haemoglobin A1c (HbA1c) was measured by high‐performance liquid chromatography and fasting plasma glucose and lipid profiles by enzyme‐linked immunosorbent assay kits. In all, 98 subjects aged 40.7 years completed the trial (48 in the date kernel group and 50 in the placebo group). After 12 weeks, date kernel supplementation resulted in a significant decrease in HbA1c [mean (SD): −0.45 (0.36)] and fasting plasma glucose compared to the placebo [−0.16 (0.27)]. No significant change was observed in the lipid profiles of the total participants. However, date kernel decreased cholesterol and triglyceride (TG) in hypercholesterolaemic and hypertriglyceridaemic participants compared to the placebo. Date kernel improved glycaemic markers in overweight or obese women compared with the placebo. Furthermore, a significant reduction in total cholesterol and TG was observed only in hyperlipidaemic subjects. Date seed is a source of valuable components, including dietary fibre and bioactive compounds, that could provide economic, nutritional, and health benefits to the nutraceutical and food industries.

Recycling of date kernel powder (DKP) in mass concrete for mitigating heat generation and risk of cracking at an early age

Mass concrete in many structural and non-structural applications is prone to early age cracking and chemo-damage from the exothermic hydration reactions of the cement binder. Date kernels are a waste product generated in large quantities in the date processing industry in the Middle East, North Africa and other countries worldwide. The use of calcined date kernel powder (DKP) as a mineral admixture in concrete to reduce the heat of hydration and temperature rise in mass concrete is a novel idea for which no prior research has been condcuted. A combined experimental and numerical investigation was conducted to assess the performance of DKP as a heat-reducing material in mass concrete. Concrete mixes with 10%, 20% and 30% DKP replacing cement and similar mixes with fly ash (FA) were investigated for evolution of mechanical and thermal properties and the adiabatic heat of hydration. 3D finite element models of mass concrete blocks 2mx2mx2m in size were validated using the data obtained from similar blocks in field instrumented with thermocouples. The 3D FE model was subsequently used to predict the heat of hydration, temperature rise and cracking index of a mass concrete block with 30% DKP powder. Experimental results showed a significant reduction in the heat of hydration in DKP concrete, with levels comparable to the FA concrete without a significant impact of strength properties. The DKP waste material has a strong potential for reducing heat of hydration in mass concrete structures, thereby promoting waste utilization, recycling and sustainability.

Improving the Functional Performance of Date Seed Protein Concentrate by High-Intensity Ultrasonic Treatment.

Date kernel is a plant-derived byproduct that has the potential to be converted into a high-value-added food ingredient, such as protein concentrate, in the food industry. Ultrasound, which is an alternative method for improving the functional properties of food proteins, is an effective physical treatment for modifying protein functionality. Solubility is the main criterion that primarily affects other functional properties of protein concentrates, such as emulsification, foaming, and water and oil binding. The aim of this study is to enhance the techno-functional performance of date seed protein concentrate (DSPC) by maximizing the solubility via a high-intensity ultrasound (HIUS) treatment at a fixed frequency of 20 kHz. The effect of ultrasonic homogenization under varying amplitudes and times (amplitude of 40, 60, and 80% for 5, 10, and 15 min, respectively) on the functional properties of the DSPC was investigated by using the response surface methodology (RSM). A face-centered central composite design (FC-CCD) revealed that the optimal process conditions of HIUS were at an amplitude of 80% for 15 min. The physicochemical and functional properties of the ultrasound-applied concentrate (DSPC-US) were determined under the optimum HIUS conditions, and then these properties of DSPC-US were compared to the native DSPC. The results showed that the solubility of all DSPC samples treated by HIUS was significantly (p < 0.05) higher than that of the native DSPC. In addition, emulsion activity/stability, foaming activity/stability, and oil-binding capacity increased after HIUS homogenization treatments, whereas the water-binding capacity decreased. These changes in the techno-functional properties of the DSPC-US were explained by the modification to the physicochemical structure of the DSPC (particle size, zeta potential, SDS-PAGE, SEM, FTIR, DSC, free SH content, surface hydrophobicity, and intrinsic emission). This work revealed that HIUS could be an effective treatment for enhancing the functional properties of date seed protein concentrate.

Stimulation of ACE inhibitory and improving α-amylase and α-glucosidase and antioxidant activities of semi-prepared and dry soup by incorporating with date kernel powder.

Date kernel as a functional food component has a special importance due to its rich nutritional profile, low price, and ease of access. For this, in this research, the sub-product was used for formulation of semi-prepared dry soup (SPDS); the effect of adding 0 (S1=control), 2 (S2), and 4 (S3) %w/w date kernel powder (DKP) on physicochemical, nutritional, and organoleptic properties and beneficial effects of SPDS samples were evaluated. The results revealed that S2 and S3 samples were different from the control sample in some physicochemical properties so that viscosity increased 1.27 and 1.52 times and a* raised 5.6 and 8.5 times, respectively, while L* decreased 0.94 and 0.88 times and b* reduced 0.92 and 0.8 times, respectively. The nutritional properties of S2 and S3 samples compared with the control sample improved. Also, differences were observed in the beneficial effects of S2 and S3 compared with the control sample as total polyphenol content (TPC) increased 1.06 and 1.11 times, respectively (p < .05); antioxidant activities (AA) of S2 and S3 samples were 8.04 and 6.01 mg/ml and angiotensin-converting enzyme (ACE) inhibitory activities were measured to be 8.2 and 7.86 mg/ml, respectively; also, α-amylase and α-glucosidase inhibitory activities of S2 and S3 samples were observed 4.48% and 5.70%, and 4.59% and 6.36%, respectively. From the organoleptic aspect, S3 had the highest acceptability. Generally, it is concluded that with the addition of DKP (maximally 4%w/w) to SPDS formulation, a functional soup could be produced considering the rich nutritional profile of DKP.

Investigating the Potential Use of Date Kernel Ash (DKA) as a Partial Cement Replacement in Concrete.

The palm and date sector is one of the most important sectors in Saudi Arabia. The total number of fertile palm trees in Saudi Arabia is about 31 million. In the production of pitted dates, date molasses, date paste, and date confectionery, a considerable number of date kernels are usually discarded as waste. This study reports experimental investigations conducted to evaluate the potential of waste date kernel ash (DKA), obtained by the calcination of date pits at 800 °C, as a partial cement replacement in concrete. DKA has low silica oxide and does not qualify as a pozzolanic material. The effect of DKA partially replacing the cement and acting as a filler material in concrete was investigated, and its properties were compared with two pozzolanic materials, fly ash (FA) and natural pozzolan (NP). Twelve concrete mixes in which cement was replaced with different proportions of calcined DKA (5%, 10%, 15%, 20%, and 30%), NP (10%, 20%, and 30%), and FA (10%, 20%, and 30%) were investigated in the experimental program. The properties of DKA, FA, and NP concrete mixes were evaluated in fresh and hardened states, including the heat of hydration, mechanical characteristics, and thermal properties. The results show that replacing cement with 5% date kernel ash increases the compressive strength by 0.42%, 3.2%, and 2.5% at 3, 7, and 28 days, respectively, while the 28-day compressive strength decreases by 2.4%, 5.4%, 16.3%, and 26.69% when the cement is replaced with 10%, 15%, 20%, and 30% DKA, respectively. Date kernel ash concrete mixes with 10%, 20%, and 30% replacement levels demonstrated higher compressive and tensile strengths and lower thermal conductivity, density, and workability when compared to natural pozzolan and fly ash. DKA is a promising partial cement replacement material; nevertheless, additional research is required to assess the durability of DKA in concrete.
