What is the difference between a floral concrete and a floral absolute extract?

Concrete is the initial hydrocarbon solvent extract of fresh flowers — a waxy, semi-solid material containing waxes, pigments, chlorophylls, and aromatic compounds. Absolute is produced by washing the concrete with ethanol, which dissolves the aromatic compounds but not the waxes, yielding a highly concentrated, wax-free aromatic liquid preferred by perfumers for its true-to-flower scent profile.

Which flowers can be processed in Mechotech's concrete and absolute extraction plant?

Our plants are engineered for rose (Rosa centifolia and damascena), jasmine (J. grandiflorum and sambac), tuberose, marigold, gardenia, and ylang-ylang. Each botanical requires specific solvent ratios, extraction temperatures, and contact times that Mechotech configures per specification based on the flower's aromatic compound profile.

Why is solvent extraction preferred over steam distillation for rose and jasmine absolutes?

Rose and jasmine contain proportionally large amounts of heat-sensitive aromatic molecules — notably indole in jasmine and rose oxide, geraniol, and citronellol in rose — that are partially hydrolysed or volatilised by the heat of steam distillation. Solvent extraction at near-ambient temperature (15–25°C) preserves the complete aromatic bouquet, which is why fine perfumery exclusively uses rose and jasmine absolutes rather than steam-distilled essential oils.

What solvents are used in Mechotech's floral concrete extraction plant?

Traditional plants use food-grade hexane for concrete extraction, which is then removed by vacuum evaporation. Mechotech also supplies plants configured for food-grade ethanol extraction (for food and beverage applications requiring no hydrocarbon solvent residues) and supercritical CO₂ extraction for premium cosmetic and pharmaceutical-grade absolutes with zero solvent residue.

Rose Concrete & Absolute Extraction Plant

Mechotech designs and manufactures industrial rose concrete and absolute extraction plants for Rosa damascena and Rosa centifolia, using food-grade hexane maceration followed by ethanol washing to yield highly concentrated floral absolutes. Our GMP-compliant systems are engineered to preserve the delicate aromatic compounds — citronellol (25–40%), geraniol (10–22%), and nerol — that define premium rose absolute. Plants are available in batch capacities from 100 kg to 5,000 kg fresh petal charge per cycle.

Jasmine Concrete & Absolute Extraction Plant

Mechotech manufactures industrial jasmine concrete and absolute extraction plants for Jasminum grandiflorum (Spanish jasmine) and Jasminum sambac (Arabian jasmine), using cold food-grade hexane maceration followed by ethanol washing. The process preserves the heat-sensitive aromatic signature — benzyl acetate (15–28%), linalool, benzyl benzoate, and phytol — that makes jasmine absolute one of the most commercially valuable floral extracts in perfumery. Systems are available from 50 kg to 3,000 kg fresh flower charge per batch.

Tuberose Concrete & Absolute Extraction Plant

Mechotech designs and builds industrial tuberose (Polianthes tuberosa / rajnigandha) concrete and absolute extraction plants using cold food-grade hexane maceration followed by ethanol washing. Tuberose absolute — containing benzyl alcohol, benzyl benzoate, methyl benzoate, and farnesol — commands among the highest prices in the global floral absolute market, making efficient and low-loss extraction critical to commercial viability. Our plants are sized from 50 kg to 2,000 kg fresh flower charge per batch and manufactured to GMP and IFRA compliance standards.
