1.2. Production and use. Information available in 1995 indicated that d-limonene was produced in Australia, Brazil, Germany, Japan and the United States (Chemical Information Services, 1995).. d-Limonene has been used for many years as a flavour and fragrance additive in foods, beverages and consumer products.It is increasingly used as a solvent. …
Abstract. This mini review describes novel, biotechnology-based, ways of producing the monoterpene limonene. Limonene is applied in relatively highly priced products, such as fragrances, and also has applications with lower value but large production volume, such as biomaterials. Limonene is currently produced as a side …
Limonene is, with the possible exception of α-pinene, the most frequently occurring natural monoterpene. It is a major constituent of the oils of citrus fruit peel and is found at lower levels in many fruits and vegetables. It occurs naturally in the d (or R)- and l (or S) optically active forms and as dl mixtures including the optically inactive racemate (dipentene). For …

School of Land and Food Sciences, University of Queensland, Brisbane, Australia. The efficiency of sonication and microfluidization to produce nano-emulsions were evaluated in this study. The purpose was to produce an oil-in-water nano-emulsion of d-limonene to apply it in the next step for nano-particle encapsulation.
A novel microbial limonene production process at industrial plant scale is designed. • Limonene is recovered by a new combined gas-stripping/solvent-scrubbing …
Given the volatile nature of limonene (vapour pressure ~260 Pa @ 25 °C) as well as its insolubility in water (<10 mg/L water), both recovery techniques seem compatible with the fermentation process.
Abstract. Bergamot essential oil (BEO) possess antimicrobial, antiproliferative, anti-inflammatory, analgesic, neuroprotective, and cardiovascular effects. However, it is rich in volatile compounds, e.g., limonene, that are susceptible to conversion and degradation reactions. The aim of this communication was to prepare a conjugate …
D-limonene and geranial fractionation from lemon … Re-garding d-limonene, the highest temperature (30 ºC) used, led to higher yields of d-limonene. Lower feed flow rate (0.6 ml min -1) led to low concentrations of d-limonene (320 g kg -1) and ... اقرأ أكثر...
The effect of limonene on cell damage leading to death of E. coli was further authenticated using microscopy. On the basis of viability test, limonene treated E. coli cells appeared red in color ...
Download scientific diagram | Flow chart for limonene extraction from publication: Experimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling Mud |...
D-Limonene is found naturally in a variety of citrus plants, such as limes, oranges, lemons, and kaffir limes, and is commonly used as a flavoring agent in the food industry, as well as in cosmetic products like shampoos, lotions, and soaps. The limonene can be extracted from the fruit peel using steam or organic solvent.
Because the effective cross-sectional area available to vapor flow affects the capacity of a ... H., Pantea, D. M. & Roy, C. Production of dl-limonene by vacuum pyrolysis of used tires. J. Anal. ...

Limonene is a chemical found in the rind of citrus fruits, such as lemons, limes, and oranges.It is especially concentrated in orange peels, comprising around 97% of this rind's essential oils ...
Learn about the chemical properties, structure, and spectra of D-Limonene, a natural citrus flavor and fragrance, from NIST Chemistry WebBook.
Minimum limonene selling prices are estimated over a range of fermentation productivity based on the calculation of net present value using discounted cash flow method. Under 45% of the maximum theoretical yield, the selling price reaches $19.9/kg, which could be competitive with established production processes when fermentation productivity ...
Procedures The flow chart shows the procedures followed to produce a CICAD. ... 1991). The annual worldwide production of d-limonene and orange oil/essence oil (95% d-limonene) in 1991 was approximately 45 kt (Florida Chemical Co., 1991). Citrus plantings under way are expected to increase that figure to 73 kt annually within a decade (IARC ...
Orange peels (OPs) were valorized in a lab-scale biorefinery loop for the recovery of limonene and the subsequent production of volatile fatty acids (VFAs) and activated carbon (AC). Solid/liquid extraction of limonene was optimized using n-hexane at 85 °C with an OPs-to-solvent ratio of 2:1, allowing for a limonene recovery yield of …
