Abstract For the large demand but low acquisition efficiency of the black olive kernel, the automatic assembly line instead of the traditional artificial olive kernel, automatically complete the shell breaking and kernel, kernel screening. Based on the design requirements of kernel extraction, we determine the overall structure of the olive kernel machine. Focus on analyzing material conveying device and cutting and shell breaking device, in the pipeline design, mainly use vibration disc, linear feeder, sprocket conveyor, pneumatic pressure device and linear screening machine and other institutions. Furthermore, three machining-sized molds were designed for the irregularities of the olive core. Finite element analysis showed that the design organization are reasonable.

LE002 and MT087 cultivar candidates had olive fruits their color is never turn black from green until they fall down. So that their olives described as evergreen fruit. In this study olives were harvested at of first day of November normally other olive cultivars have whole black olive but LE002 and MT087 have green olives. Oil and dry matter content of LE002 and MT087 fruits were determined after that oils were produced by cold press and free fatty acid content, peroxide value and absorbency in ultraviolet light of oils were detected. Dry matter and oil content of olives were 41,0% and 19,47% for MT087 and 45,96% and 23,42% for LE002. Oil content of green olives were lower than these detected values for Marmara region of Turkey. All the analyses result of oils was between the limits of olive oil standards and regulations. So that both these cultivar candidates should be more analyzed to be determine their oil characteristics for future cultivar registration and certification steps.

This study we have conducted an ethnobotanical survey and antimicrobial activity in Tetouan province to identify the use of the famous plant species in traditional medicine : fig tree and Olive and follow-up of antimicrobial activity during three stages for green, pink and black olives and mixing activity of olive and fig extracts. 80 questionnaire sheets were done during April-June 2019, and the method of diffusion was used for the antimicrobial activity.Bacteria and yeasts were used: Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae, E.coli and Candida albicans. The results revealed that 32% of farmers use olive oil for the initial treatment of respiratory diseases, and 22% use it for digestive system problems and 13% use it as a treatment of the nervous system.However, fig tree is used against insect bites, as an inhibitor of the growth of certain cancerous tumors, diabetes and certain viral infections. The ethanol extracts showed good inhibitory effects against most strains of bacteria and yeast. Also for the majority of strains tested, it was found that in December (black olive), activity is stronger, and that the mixture of ethanol extracts with ethanol extracts of fig tree it strengthened them.

Abstract In the current study, the mechanistic understanding of the adsorption isotherm and thermodynamic aspects of cationic methylene blue (MB) dye adsorption onto cellulosic olive stones biomass from wastewater were investigated. The batch adsorption of MB onto the olive stones (black and green olive stones) was tested at a variety of pH, dye concentrations, temperatures, and biomass particle sizes. The adsorption thermodynamics such as Gibbs free energy, enthalpy, and entropy changes were also calculated. Moreover, the desorption studies of MB from the spent olive stones were studied to explore the re-usability of the biomasses. The results revealed that under the optimum pH of 10, the maximum MB uptake was achieved i.e. 80.2% for the green olive stones and 70.9% for the black olive stones. The green olive stones were found to be more efficient in remediating higher MB concentrations from water than the black olive stones. The highest MB removal of the green olive stones was achieved at 600 ppm of MB, while the highest MB removal of the black olive stones was observed at 50 ppm of MB. Furthermore, for almost all the concentrations studied (50–1000 ppm), the MB adsorption was the highest at the temperature of 45 °C (P value < 0.05). It was shown by the Fourier transform infrared that the electrostatic interaction and hydrogen bonding were proposed as dominant adsorption mechanisms at basic and acidic pH, respectively. While the hydrophobic-hydrophobic interaction was a dominant mechanism at neutral pH. The thermodynamic studies revealed that the adsorption process was endothermic, spontaneous, and favorable. Moreover, the real wastewater experiment and the desorption studies showed that the green and black olive stones were a cost-effective and promising adsorbents for MB remediation from wastewater on account of their high adsorption and desorption removal capacities.

Background: Black olive contains considerable concentrations of phenolic compounds, which can result in a higher antioxidant component compared with green olives. Sometimes, as food fraud, the use of unwanted substances has been observed such as iron sulfate or iron particles for blackening olives, eventually causing adverse effects on the tissues of the digestive tract, brain, kidney, and liver in the consumer. The main purpose of this study was to determine flavonoids, iron content and ion sulfate in canned black olives. Methods: Canned black olive from inland/imported and traditional/industrial samples were collected. The amount of iron, sulfate ion, and flavonoids content were measured by ICP-OES and spectrophotometer, respectively. Results: Industrial black olives (brand N) from Turkey showed the highest iron content (110.17 mg/kg) and traditional black olives purchased from Rudbar, showed the lowest iron content (6.72 mg/kg). These values were lower than the iron limit in canned black olives (150 mg/kg). The highest and lowest levels of sulfate were also found in the traditional black olive of Rudbar and industrial black olives of Greece, respectively. Sulfate amount was determined between 23.225-82.102 mg/kg. Traditional black olives of Roudbar had the highest flavonoid, and the lowest flavonoid content was shown by the industrial black olive of Turkey. The pH was in the range of 4.4-4.8, indicating that the pH of any of the samples was not higher than the standard maximum level. Conclusion: According to the results of this study, iron sulfate has not been added intentionally to the collected samples.

The influence of adding Sodium Perborate Tetrahydrate (NaPB) and tetraacetylethylenediamine (TAED) on the efficiency of removing soils from cotton fabric was evaluated in the study. NaPB as inorganic peroxide and TAED as a bleach activator were added to a commercial washing powder agent. Four standard soils applied on cotton fabric (EMPA standard soiled fabrics) were used in the study, i.e. 101 – carbon black/olive oil, 114 – red wine, 116 – blood/ milk/ink and 160 – chocolate. The washing of fabrics was conducted in accordance with the SIST EN ISO 105-C06 standard at 40, 60 and 90 °C in Launder-Ometer apparatus. The washing efficiency was evaluated by determining the CIE L* colour coordinates of the unwashed and washed fabric samples, and the difference in ΔL* colour coordinates among them. The results showed that NaPB and TAED improve the efficiency of washing for two standard soils, have no effect on one, and deteriorate the washing results of one standard soil.
