“…However, previously reported estragole (33.0-37.4%) and fenchone (22.5-26.5%) as main compounds in fennel hydrolate [47]. Hop possesses very strong cheesy odour which originated from isovaleric acid, main compound from hydrolate, what is previously reported by Lazarević et al [41]. Lavender hydrolate is the most studied hydrolate, and all authors referred linalool and linalyl acetate as dominant compounds in hydrolate of lavender species [48, 49,50,51].…”

“…Moreover, thyme hydrolate has negative effect on the germination of soybean, sun ower, maize, clover and alfalfa, as well as weeds (Amaranthus retro exus, Chenopodium album, Portulaca oleracea, Echinochloa crus-galli, Sorghum halepense, and Solanum nigrum) [38]. In addition, hop and angelica hydrolates in lower concentrations (10 and 20%) stimulate germination of big seeds such as corn and in higher concentrations (50 and 100%) as suppressed germination especially in a small seeds such as A. retro exus [41].…”

“…The closeness of the vectors representing the observed compounds and the points representing the samples makes it clear which hydrolate is the richest in each compound. There are several studies that reported the antimicrobial activity of hydrolates, among them peppermint and oregano [53,54,55], while for hop hydrolate previously is reported no antimicrobial activity [41]. On the other side, there are a lack of information about the antimicrobial potential of other investigated hydrolates (fennel, lavender, and lemon catmint), but for their essential oil it is reported [56,57].…”

Sprouted seeds and microgreens are emerging as innovative specialty raw salad crops, valued for their health-promoting properties. However, the risk of foodborne illnesses associated with microbial contamination in microgreens underscores the need for effective sanitization in their production. This study explores using hydrolates, by-products of essential oil distillation from six plants, as natural sanitizers in alfalfa microgreen production. The research investigates their impact on seed germination, antimicrobial activity, and sensory attributes. Results revealed that oregano, fennel, lavender, and lemon catmint hydrolates decrease alfalfa seed germination, while peppermint and hop hydrolates have no signi cant impact. Peppermint and fennel hydrolates demonstrate notable e cacy in antimicrobial testing. Sensory analysis indicates differences in odour and avour, with peppermint, oregano, and lavender receiving high scores. According to the results, peppermint hydrolate can be considered a favourable option for alfalfa micro sprout production, contributing to sustainable and organic approaches in urban agriculture and underlining the importance of natural sanitizers for food safety. Statement of NoveltyEssential oils are widely used in the food and pharmaceutical industry, but hydrolates, their accompanying by-products, are usually discarded, or used in a small scale in the cosmetic industry. Research has con rmed that hydrolates possess a pleasant scent, mainly similar to the corresponding oils (rarely unpleasant scent, completely different from essential oil) and certain biological activities (antimicrobial, antioxidant, allelopathic, etc.). They have the potential to be used in organic agriculture, as well as in food processing. Bearing in mind the constant world trend of applying innovative classes of specialty raw salad crops, such as microsprouts and microgreens, the application of hydrolates can be of great importance in order to improve its taste and microbiological safety. HighlightsMicro sprouts are prevalentraw salad crops with functional properties Alfalfa sprouting was done in water or six selected hydrolates during 10 days Peppermint, oregano, fennel, hop, lavender and lemon catmint hydrolates were used All hydrolates except peppermint and fennel showed a dose-dependent sprouting inhibition Peppermint hydrolate showed the best antimicrobial and sensory potential across different microorganisms also highlight the importance of considering both the hydrolate source and microbial target in formulating effective growth suppressing strategies in micro sprouts and other food-related production [30]. ConclusionsIn light of the results from germination tests, evaluations of antimicrobial potential, and sensory analyses, peppermint hydrolate emerges as a promising option for cultivating alfalfa microgreens. The study underlines the considerable potential of peppermint hydrolate as a favourable choice for incorporation into the production of alfalfa microgreens, given its positive impact on germination, a...

Objectives The present study focused on exploring the chemical composition of essential oil and corresponding hydrolate obtained by steam distillation of industrial hemp ( Cannabis sativa L.) cultivar “Helena” (low THC content). Methods Chemical characterization of industrial hemp essential oil and hydrolate was performed by gas chromatographic and gas chromatographic-mass spectrometric analysis, while biological activities included antimicrobial and antioxidant tests. Antimicrobial activity was determined by measuring diameters of the inhibition zone by using a disc-diffusion method with nine microbial strains from ATCC culture. Moreover, minimal inhibitory concentration (MIC) as well as time-kill kinetic studies, antiadhesion, and antibiofilm formation potential were also evaluated. Antioxidant activity was evaluated through three different antioxidant assays: 2,2-diphenyl-1-picrylhydrazyl (DPPH●), 2,2′-azinobis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS●+), and reducing power (RP). Results The gas chromatography mass spectrometry analysis showed that the main compound in the essential oil was trans-caryophyllene (37.4%), followed by caryophyllene oxide (12.4%) and α-humulene (11.0%), while in the hydrolate it was 1,8-cineole (11.5%). Results showed that industrial hemp essential oil and hydrolate exhibited no antimicrobial activity against gram-negative bacteria, yeasts, and fungi, while gram-positive bacteria were sensitive. Therefore, in the following step, MIC was determined by microdilution method. The lowest MIC for essential oil (12.5%) was obtained for Enterococcus faecalis and Staphylococcus aureus, while this value doubled for Listeria monocytogenes. Conversely, the MIC for hydrolate was 100% for all gram-positive bacteria. Antioxidant activity showed that industrial hemp essential oil and hydrolate have potential as natural sources of antioxidants. Conclusion This research confirmed the previously proven antimicrobial and antioxidant activities of industrial hemp essential oil. The novelty lies in the antimicrobial and antioxidant activity of hydrolate, which is practically waste, but has great potential to be a useful by-product.
