A possible way to valorize citrus peels, which are byproducts of the juice extraction industry, is to use them as natural biopreservatives. In this paper we present early results from a compared Solvent Free Microwave Extraction (SFME) with Hydro-Distillation (HD) and Cold Pressing (CP) of essential oils (EOs) using fresh orange peel (Citrus sinensis L. var. Valencia late), a by-product in the production of orange juice in Algeria. The EOs were analyzed by gas chromatography coupled to mass spectrometry (GC-MS). All extracted C. sinensis EOs were chemotype limonene (94.64 to 95.48%). SFME is performed without added any solvent or water. SFME increases EO yield and eliminate wastewater treatment, resulting in a great progress in terms of time and cost efficiency. In its second part, the present study was conducted to evaluate “in vitro”, the antioxidant activities of Solvent Free Microwave (SFM) extracted orange EO by using the DPPH• (2,2-di-phenyl-1-picrilhydrazyl) free radical scavenging assay. The ability of orange EO to scavenge the free radical DPPH• was high, exceeding 80%. The result of the DPPH assay gives an IC50 range value of 89.25 μg/mL (0.09 mg/mL) for the studied sample. Accordingly to the scientific literature, C. sinensis EO tested in the present study presented strong antioxidant activity, when looking to its values of AAI = 1.12 μg/mL. The feasibility of biopreservation used EOs as an alternative to synthetic techniques for liquid whole egg (LWE) stored under commercial retail conditions was investigated. The orange EO extracted by SFM was screened for its antibacterial and antioxidant activities in LWE at concentrations of 0.1, 0.3 and 0.5%. The TBA-RS results showed that the EO treatments significantly (p < 0.05) reduced the lipid oxidation in LWE. The long term oxidative, microbial and organoleptical stability of the LWE during display was positively influenced by orange EO treatments. Therefore, the results obtained here confirm that EO treatment as a promising technology to extend the commercial shelf-life of liquid egg products during retail/display.

Bedbugs are harmful human blood-sucking ectoparasites. The disadvantages of a bedbug bite cause itching, redness bumps, secondary infections, and anemia in children. Bedbugs controller so far uses harmful chemical pesticides, but reappearance of bedbugs indicates less effective chemical pesticides, and becomes a serious problem. So it needs safer controller for human health. This study aims to analyze the d-Limonene activity of orange peel (Citrus sinensis L.) in controlling the bedbug infestation (Cimex cimicidae). The study was conducted through 5 stages: d-Limonene isolation, GC-MS characterization, bioassay Y test d-Limonene nanoparticles, SEM characterization, and d-Limonene activity test on bedbug. The results showed that the essential oil of orange peel contained the main compounds as d-Limonene (90.018%), 1,6-Octadien-3-ol, 3,7-dimethyl- (3,017%), β-Myrcene (2.071%), Octanal (0.349%), 1-Octanol (0.589%), 1R-α-Pinene (0.688%), 6-Octen-1-ol, 3,7-dimethyl- (0.667%), 3-Cyclohexene-1- methanol, α, α, 4-trimethyl-, (S) - (1.453%), and Bicyclo [3.1.1] heptane, 6.6-dimethyl-2-methylene-, (1S) - (1.147%). The Bioassay Y test shows that d-Limonene was both repellent and fumigant, d-Limonene nanoparticles had uneven and irregular surface morphology, and in the flea activity test showed more than 50% bedbugs death. These research concluded that d-Limonene compounds from sweet orange peel had activity to control the bedbugs.

Date palm seed oil is among the precious vegetable oils with low yield, whose extraction is commonly done with organic solvents which cause serious problems. This study aims to assess the effectiveness of orange peel essential oil as biosolvent for date seed oil extraction. Green extraction was conducted by Soxhlet apparatus as well as by soaking and compared with the Soxhlet method using petroleum ether. The GC-MS analysis of orange peel essential oil confirmed its richness with limonene (94.31%), which justifies its usefulness as green solvent. The latter gave higher yields, the extracted bio-oil was light brown with pleasant odor, and the characteristics were consistent with international standards. Based on the GC profiles, obtained oils were similar using both solvents, and the major compounds were oleic and lauric acids. The bio-oil phenolic content and the antioxidant activity were high, and the major compounds were the protocatechuic, chlorogenic, and 4-O-caffeoylquinic acids. Gallic and p -coumaric acids were the major compounds for oil extracted by petroleum ether.

Supercritical Carbon

Limonene constitutes 98% of the essential oil obtained from orange peel. Besides being used as fragrances and flavours in the food, perfume and cosmetic industries, limonene is also a good degreasing agent. Supercritical carbon dioxide is an excellent solvent for non-polar compound like limonene but poor solvent for polar compound like α-terpineol. Common practice in supercritical fluid extraction is to change the polarity of supercritical carbon dioxide by employing polar modifiers to increase its solvating power towards polar analytes. Base on this, in the attempt to extract more limonene in orange essential oil, less polar modifiers were added instead. In this study, effects of adding modifiers with different polarity on extraction of aroma compounds (limonene, linalool and α-terpineol) from Citrus Sinensis L. Osbeck or sweet orange peel were investigated. Supercritical extraction was carried out at defined pressure and temperature for duration of 45 minutes. Concentration of aroma compounds extracted was analysed using GC-MS. The optimum conditions for extraction were observed at 318K and 12MPa. The concentrations of limonene increased significantly by the addition of methanol and slightly with n-heptane. It was also found that n-heptane is effective on supercritical CO2 extractions of linalool and α-terpineol.

Quality And Shelf Life

Pangasius fillet has high demand in the international market due to its tender flesh, delicate taste and as an affordable substitute for cod and other more expensive white fishes. The preliminary study, it was found that the optimized condition for soaking was NaCl 1.32%, STPP 1.88%, and sorbitol 4.68% for 30 mins which give a significant effect (p<0.05) to the yield, water activity, pH, and improvement in the sensory of the treated fillet. However, the soaking itself was not contributed to the extension of shelf life. This study aimed to examine the effects of Pangasius fillet soaked in essential oil on the quality and shelf life with simulated storage similar to retail conditions. Lemongrass essential oil was showing the best result in improving the quality and shelf life of Pangasius fillet stored in refrigerated storage (0-4˚C). The addition of 0.2% lemongrass showed 7 days extension of shelf-life or longer compared to fillet without soaking and fillet soaking without essential oil. In addition, it also reduces the Total Volatile BasedNitrogen (TVB-N) content, improves the sensory quality (raw and cooked) of Pangasius fillet. Mint essential oil was showing the shelf-life extension (7 days longer) and sensory improvement at 0.3% concentration. However, the mint essential oil was not showing better TVB-N reduction in treated fillet compared to fillet soaking without essential oil. Therefore, it is recommended to incorporate 0.2% lemongrass essential oil for the Pangasius industry to extend the shelf life of Pangasius fillet followed with quality improvement
