AI Article Synopsis
- Limonene is a common natural terpene found in citrus fruits and peppermint, with (R)-limonene being the most abundant form.
- It is a low-cost, biodegradable substance often sourced from agricultural waste like citrus peels, and can be converted into valuable products used in food, cosmetics, and pharmaceuticals.
- The review discusses recent research on using heterogeneous catalysts to improve the efficiency of converting limonene into these various products.
Article Abstract
The natural terpene limonene is widely found in nature. The (R)-limonene (the most abundant enantiomer) is present in the essential oils of lemon, orange, and other citrus fruits, while the (S)- limonene is found in peppermint and the racemate in turpentine oil. Limonene is a low-cost, low toxicity biodegradable terpene present in agricultural wastes derived from citrus peels. The products obtained from the conversion of limonene are valuable compounds widely used as additives for food, cosmetics, or pharmaceuticals. The conversion of limonene to produce different products has been the subject of intense research, mainly with the objective of improving catalytic systems. This review focused on the application of heterogeneous catalysts in the catalytic conversion of limonene.

Assessing the Role of Myxobacteria Isolates in the Biotransformation of Flavoring Substances.
Curr Microbiol
March 2025
Department of Chemistry, Universitas Tanjungpura, Pontianak, Indonesia.
Myxobacteria are well known for producing secondary metabolites with various potential applications, including volatile compounds that serve as flavors, although this capability is less documented. This study characterizes the morphology of six Myxococcus strains (InaCC B1497, B1482, B1498, B1483, B1484, and B1486) obtained from the Indonesian Culture Collection (InaCC) and evaluates their potential for flavor biotransformation. Morphological observations were conducted on fruiting bodies, vegetative cells, myxospores, and colony shapes using dissection and binocular microscopes.

Gels
December 2024
Department of Food Science and Technology, Ionian University, 28100 Argostoli, Greece.
Spent coffee grounds, the main by-product of the coffee-brewing process, were valorized as a renewable source of lipids for the synthesis of novel wax esters and as an alternative and sustainable oil-structuring agent for the production of oleogels. The lipase-catalyzed reactions were implemented using fatty alcohols both under solvent-free conditions and with limonene as an environmentally friendly solvent. Wax esters were evaluated for their ability to formulate olive oil oleogels through the determination of the physical properties of oleogels.

Article Synopsis
- The study explored the use of orange peels to create porous activated carbons through chemical activation, which were then tested as metal catalyst supports for limonene oxidation.
- Characterization of the materials included analytic techniques such as N2 sorption, XRD, FTIR, SEM, XPS, and XRF to evaluate their properties and elemental composition.
- Results indicated that modifying activated carbon with cobalt and molybdenum significantly enhanced catalytic activity, with the molybdenum-based catalyst achieving a selectivity of 37% for limonene oxide at a conversion rate of 58%.
Inhibition effect of non-contact biocontrol bacteria and plant essential oil mixture on the generation of -nitrosamines in deli meat during storage.

To reduce the risk of -nitrosamines in deli meat products, this study formulated a novel non-contact -nitrosamines inhibiting preservative IV (NIP-IV) consisting of biocontrol bacteria and plant essential oils (EOs) ( SR-1 + PP-2 + CF-3+ cinnamon EO + grapefruit EO). Luncheon pork, spiced beef, and red sausage were taken as representatives of typical deli meat products and used to validate the effectiveness of NIP-IV in inhibiting -nitroso dimethylamine (NDMA) production. The results showed that NIP-IV restrain protein degradation and lipid oxidation in deli meat products and effectively control microbial activity.
