“…According to many cited articles [6,[22][23][24], Clove contains many phenolics, tannins, flavonoids, essential oils, .  Perforated tube may be used with less solvent quantity for better continuous extraction series however Soxhlet must be used with more than half flask volume to get fast and efficient extraction.…”

In this paper, a new efficient extraction tool of bioactives from plant parts was designed, applied, and compared with Soxhlet apparatus. This tool was a Quickfit®- Pyrex® glass tube perforated easily inserted in round flask containing solvent. Clove buds in both non-grinded and grinded form were analyzed by GC-Mass. Our observations were gotten from designing and using perforated tube compared to Soxhlet apparatus for Clove buds’ extraction. It is a simplest tool in designing and handling than Soxhlet apparatus that ensured more contact between Clove buds in their bag and used solvent than Soxhlet. Employing bag sewed from face mask is low cost than high quality Soxhlet - cellulose thimble. Furthermore, this sewed bag can be discharged from its content, cleaned, and reused but expensive cellulose thimble is made for one use. Perforated tube presents a good choice for efficient-short extraction time, minimum sample weight and solvent volume resulting higher quantity of Clove bioactives compared to Soxhlet. By analytical foundations, using grinded Clove gave different qualitative-quantitative analysis of the tested bioactives in the extracted solution compared to non- grinded buds. Eugenol was the major constituent in non- grinded buds while grinded powder gave 2-methoxy-3-(2-propenyl)-phenol as a maximal bioactive. This new tool may be used with less solvent quantity for better continuous extraction series however Soxhlet must be used with more than half flask volume to get fast-efficient extraction. Also, Soxhlet needs direct heating source however perforated tube may be applied in both direct heating and water bath. These notes are important in using low boiling solvent (volatile) for better extraction. Because extraction is not limited to plant parts, this new tool may be used as a general extraction tool. So to guarantee getting higher quantities of volatile constituents with easier steps, perforated tube is an excellent choice.

“…In other words, the supercritical state of a fluid is the state in which the properties of a liquid and a gas are the same. Additionally, SFs offer greater transportation qualities than liquids because their density, unlike that of liquid solvents, may be altered by adjusting the pressure and temperature ( 47 ).…”

Many studies have demonstrated the use of synthetic preservatives and chemical additives in food is causing poisoning, cancer, and other degenerative disorders. New solutions for food preservation with quality maintenance are currently emerging. As a result, public concern has grown, as they desire to eat healthier products that use natural preservatives and compounds rather than synthetic ones. Clove is a highly prized spice used as a food preservative and for a variety of therapeutic reasons. Clove essential oil and its principal active component, eugenol, indicate antibacterial and antifungal action, aromaticity, and safety as promising and valuable antiseptics in the food sector. Clove essential oil and eugenol are found to have strong inhibition effects on a variety of food-source bacteria, and the mechanisms are linked to lowering migration and adhesion, as well as blocking the creation of biofilm and various virulence factors. This review emphasizes the importance of CEO (clove essential oil) in the food industry and how it can be explored with edible coatings to deliver its functional properties in food preservation.
