¿Qué es Citral (Geranial/Neral)? Aplicaciones, dosis, alternativas y especificaciones

Citral, English name is Citral, also known as 3,7-Dimethyl-2,6-octadienal, es una acyclic monoterpene aldehyde orgánico compound con una strong lemon aroma. It is one of the most widely used and applied natural terpene aldehydes in the global flavor and fragrance industry, occupying an irreplaceable core application value in the food flavor industry, daily chemical fragrance industry, and pharmaceutical chemical intermediate fields. Its molecular formula is C10H16O, molecular weight is 152.23, CAS number is 5392–40–5, EINECS number is 226–394–6, and FEMA number is 2303. In terms of chemical structure, citral belongs to the acyclic terpene aldehyde class. The natural product es un mixture of two geometric isomers: the trans isomer geranial (Citral a, also known as Geranial) and the cis isomer neral (Citral b). The ratio of these two isomers es unpproximately 80%—90% geranial and 10%—20% neral. Because the physical properties of the two isomers are similar, they are usually applied in the flavor industry as a mixture. Citral contiene a reactive aldehyde group and conjugated double bond structure in its molecule, which not only gives it a strong aroma itself but also permite it to derive a series of high-value-added flavor compounds through reactions como condensation, cyclization, oxidation, and reduction, incluyendo ionone, methyl ionone, damascone, geraniol, nerol, and citronitrile. Therefore, it is known as the pearl in the crown of fine chemicals. Citral naturally occurs in various plant essential aceites como litsea cubeba aceite (content approx. 70%), lemongrass aceite (content 70%—80%), lemon aceite, lime aceite, citrus leaf aceite, and verbena aceite. Citral appears as a colorless to amarillo claro transparent líquido con una strong, fresh, persistent lemon-like aroma and no optical activity. It is volatile, soluble en most orgánico solvents como ethanol, diethyl ether, propylene glycol, glycerol, mineral aceite, and vegetable aceites, but insoluble en agua. Citral is not only the most important main flavorant for lemon-type flavors but also a key intermediate for the synthesis of ionone, Vitamin A, Vitamin E, phytol, and various high-end flavors, holding extremely high economic value and estratégico position in both the flavor industry and pharmaceutical chemistry. Because its proceso de producción is complex and the product technology is difficult, it is recognized by the industry as the technological high ground in the field of fine chemicals. El producto se utiliza ampliamente in daily chemical flavors, food flavors, perfumes, wcenizasing products, cosmetics, pharmaceutical intermediates, and natural antibacterial agents.

Citral se reconoce como the soul of citrus aroma, holding an unshakable position in the global flavor and fragrance industry, industria alimentaria, pharmaceutical chemistry, and daily chemical industry. Its most outstanding advantages lie in its strong, persistent natural lemon aroma, irreplaceability as a key sintético intermediate, good bioactivity and nature-identical properties, and broad market application prospects. 1 Strong, Persistent Natural Lemon Aroma: Citral is the purest and strongest source of natural lemon aroma in nature. Its aroma is fresh, sweet, and persistent, more natural and mellow than sintético citrus flavors. Thes unroma characteristic makes it the core materia prima for blending lemon-type, citrus-type, and bergamot-type flavors, widely used for aromatizante in foods, beverages, cosmetics, and daily chemical products. Whether in high-end perfumes or mass-market cleaning products, citral brings a distinct sense of freshness and naturalness to products. 2 Irreplaceability as a Key Sintético Intermediate: The most important estratégico value of citral lies in its role as a universal intermediate for the synthesis of downstream high-value chemical products. Through a series of chemical reactions, citral can derive various compounds with extremely high economic value in the flavor and pharmaceutical fields, incluyendo ionone (used for synthesizing Vitamin A), damascone (a core component of rose-type flavors), methyl ionone, geraniol, nerol, and citronitrile. Citral is not only a key materia prima for the synthesis of Vitamin A but also a precursor for the synthesis of important nutritional chemicals como Vitamin E and phytol. Its production is difficult and has high technical barriers, earning it the reputation of being the pearl in the crown of fine chemicals, holding a very important estratégico position in the entire industry chain. 3 Bueno Bioactivity – Natural Antimicrobiano and Insect Repellent Properties: Scientific research has shown that citral has good antibacterial, antifungal, and insect repellent properties. As a component of natural cleaning products and insect repellents, it has inhibitory effects on various foodborne pathogens como Staphylococcus aureus, Escherichia coli, and Salmonella, and also has repellent effects against mosquitoes, ticks, and mites. This property gives it broad application prospects in natural conservantes, biopesticides, oral care, and personal care products. 4 Nature-identical and Clean Label Properties: Citral naturally occurs widely in various plant essential aceites como lemongrass aceite, litsea cubeba aceite, and lemon aceite. A large number of commercial products are nature-identical products separated and extractoed de origen natural essential aceites. Thes unligns well with current global consumer preferences for natural, etiqueta limpia, and plant-based products, giving it higher consumer acceptance and market competitivoness in food aromatizante and premium daily chemical products. 5 Compliant and Safe Usage History: Citral has been approved as a permitted food flavor by multiple international authorities incluyendo China GB 2760, US FDA 21 CFR 182.60, FEMA, and EU EC 1333/2008. It also holds international religious clean certifications como KOSHER and HALAL, con una long history of safe use. Its safety assessment is fully established, and it se utiliza ampliamente globally. 6 Estabilidad and Strategic Value of Global Supply: In the past, citral production was highly dependent on two companies, BASF and NHU, con alto supply concentration, making prices and cadena de suministros vulnerable to industry fluctuations. In recent years, con el successful commissioning of Wanhua Chemical‘s 48,000 tons/year citral unit, the global citral supply pattern has undergone significant changes, greatly enhancing supply stability and providing more fiable materia prima assurance for downstream users.
