“…In addition, it seems that the interaction factor (plant In general, solid wastes obtained from the distillation of MAPs of the Lamiaceae family are reported to have high TPC, TFC, and antioxidant activity [11], with lemon balm exhibiting similar values to that of spearmint but higher than oregano, sage, rosemary, and satureja. In their study, Alice et al [39] reported that by-products from the hydro-distillation of Origanum vulgare along with Melissa officinalis showed the highest TPC compared to the other plants of the Lamiaceae family (Salvia officinalis L., Mentha piperita L., Thymus vulgaris L., and Hyssopus officinalis L.). Similarly, Ulewicz-Magulska and Wesolowski [40] have reported that oregano and thyme showed the highest contents of phenolics followed by melissa and rosemary.…”

The influence of incorporation of post-distillation solid wastes of the aromatic plants (SWAP), oregano, rosemary, lemon balm, and spearmint into wheat breads at 1% and 2% levels on their physicochemical and sensorial properties, and antioxidant and volatile profiles were investigated. SWAP breads had darker crumbs and crust and greener crumbs compared to the control, but rather similar loaf specific volume and textural attributes (crust puncture test and crumb Texture Profile Analysis). Although the mold growth on bread crumb surface was not inhibited by SWAP presence, LC-DAD-MS revealed a large increase in terpenoids, like carnosic acid (all SWAP), carnosol (rosemary) and carvacrol (oregano), phenolic (rosmarinic and salvianolic) acids and flavonoids in bread with SWAP inclusion, leading to enhanced antioxidant capacity (ABST, DPPH and FRAP assays). The distinct aromatic plant flavors were detected in the fortified breads by trained assessors and confirmed by SPME-GC/MS volatile analysis, showing high levels of terpenoids in SWAP breads, like carvacrol (oregano), caryophyllene (rosemary and lemon balm), and carvone (spearmint), and rendering the 2% fortification unacceptable by consumers. Nevertheless, breads with 1% oregano or rosemary waste had similar control overall acceptability scores, indicating that SWAP can be a promising ingredient for developing antioxidant-enriched wheat breads.

“…Wollinger et al [38] reported that an increase in hydrodistillation time up to 2.5 h had a positive effect in continuously enriching the wastewaters of R. officinalis with antioxidants. Alice et al [39] studied different Lamiaceae species and similarly reported a phenolics reduction in the main solid waste and an increase in wastewaters due to solubilization and degradation. Wastewaters in the current study amounted up to more than half (61 ± 3%) of the phenolics present in the raw material, which implies their affinity to water being enhanced by the distillation heating.…”

Lavender distillation produces huge quantities of solid waste yearly. This waste is usually discarded, resulting in serious environmental issues. However, it still contains residual essential oil and other bioactive compounds. This research reports on the development and comparison of optimized solid–liquid separation methods, i.e., microwave- (MAE) and ultrasound-assisted extraction (UAE) of phenolic compounds from lavender distillation waste. The optimal pretreatment conditions, such as waste moisture content and particle size, were also determined. The extracts were spray- or freeze-dried and the resulting powders were characterized for their physicochemical properties. The majority of the original phenolic compounds in lavender were found in the leachate fraction after distillation (61%), whereas 43% was found in the solid waste. Drying of the solid waste before extraction affected the process efficiency. UAE led to a higher phenolic content and greater antioxidant properties compared to MAE. Drying (spray or freeze) the extracts did not significantly affect their phenolic content, whereas the use of maltodextrin as a drying agent improved the drying process yield, especially when using the freeze-drying method. It is concluded that valorization of lavender distillation wastes can be achieved via an integrated process consisting of a green extraction method and a consequent drying process that results in a stable bioactive powder.
