Special Issue Information

Dear Colleagues,

The aroma composition of fruits, vegetables, and aromatic herbs has been the subject of considerable research in recent years. It is well known that the presence of volatile compounds and their composition determine the specific aroma of fruits, vegetables, and aromatic herbs. The main chemical families present in fruits, vegetables, and aromatic herbs are monoterpenes, monoterpenoids, and phenylpropanoids. In lower amounts, alcohols, sesquiterpenes, sesquiterpenoids, aldehydes, and esters are also found. The composition and concentrations of volatile compounds depend on many factors, including climatic and soil conditions, seasonal variation, agronomical practices, cultivars, varieties, etc. On the other hand, sensory analysis is used to quantitatively determine the intensities of the main sensory properties and attributes of fruits, vegetables, and aromatic herbs as well as determine the preference by consumers. Such analysis requires the use of a trained panel and regular consumers. As a result of this, the present Special Issue is aimed at gathering outstanding cross-disciplinary approaches (reviews and original research) applying the combination of instrumental analysis (volatile compounds extraction and analysis) and sensory analysis as a tool for quality control of fruits, vegetables, and aromatic herbs as affected by agronomical factors in order to provide extremely valuable information to farmers and growers or developers of new cultivars and varieties.

Kaffir lime has been widely researched for use as an essential oil, alongside its main function as an Asian spice, due to the needs of numerous industries. A meta-analysis was used to summarize the variation in yield and main components of kaffir lime essential oils in response to differences in plant origins, plant parts, and extraction methods during the last fifty years. A database was constructed from 85 data items from 36 single studies, prepared by following PRISMA-P. The result showed no significant effect of extraction method on variation in oil yield and main components. In contrast, after integrating numerous single studies under a statistical approach, some interesting facts emerged, such as (i) plant origin significantly affected the citronellol, i.e., subtropical conditions were more favorable than tropical ones; (ii) caryophyllene was found in all countries, from subtropical America and tropical Asia to tropical East Africa; (iii) the richest parts of citronellal, citronellol, citronellyl acetate, and sabinene were leaves, blossoms, twigs, and fruit peels, respectively; and (iv) due to significant interaction of plant origin and plant parts, a very challenging issue in boosting oil yield could be answered by formulating location-specific and organ-specific culture practices. This study had succeeded in providing further research directions. Full article

Thymus × citriodorus (Lamiaceae) is medicinal, essential oil-bearing hybrid, synthesizing significant amounts of geraniol. This hybrid is suitable for cultivation in an open ground in the Baltic region; therefore, increasing the yield and amounts of bioactive compounds by organic matter fertilization during organic farming is realized. The aim of the present study was to evaluate the effect of fertilization with liquid cattle dung and humus on the quantitative and qualitative composition of essential oils as well as on biomass for some morphometrical and anatomical parameters of Thymus × citriodorus that were grown in open ground for two years. Each fertilization treatment was carried out on four replications, and four separate experimental plots were used as control plots. For anatomical investigations, the impress method and light microscopy were used. The essential oils were isolated by hydrodistillation and analyzed by GC-FID and GC-MS. The results showed somewhat different effects of liquid cattle dung and humus on the investigated parameters of hybrid in the first (warmer and drier) and second (rainier and cooler) experimental years. Liquid cattle dung had positive effects on biomass, height and the area covered by plants and on the number and length of inflorescences as well as on the density of stomata in the lower epidermis in the first year, but in the second experimental year, effects were observed on the length of inflorescences only. The effect of humus on the density of glandular trichomes in the upper epidermis of leaves was positive in the first year, but negative in the second experimental year. Moreover, in the second experimental year, humus affected negatively the height of plants and the percentage of the essential oil. The conclusion was that although it is fertilized with the same organic fertilizers, different climatic conditions in different years can influence chemical, anatomical and morphometrical parameters of plants growing in an open ground.

Peach production in Georgia, USA, extends from mid-May to mid-August. Multiple cultivars are commercially grown in the U.S., and each cultivar has unique fruit quality characteristics, which could influence consumer perception and acceptability. Among those, peach flavor has been minimally characterized among cultivars. Headspace-solid phase microextraction (HS–SPME) combined with gas chromatography–mass spectrometry (GC–MS) was used to characterize the volatile profile of 42 peach cultivars commercially grown in 2016. The goal of this research was to understand the aroma composition and content of peach cultivars grown in Georgia, USA. Thirty-six volatile compounds were identified. Significant differences (p ≤ 0.0001) were observed for all the flavor volatiles across all cultivars being evaluated. Esters were the major compounds isolated from the 42 peach cultivars, followed by lactones, alcohols, aldehydes, and terpenoids, in that order. Lactones, benzaldehyde, and linalool, which are known to be peach aroma compounds, exhibited the highest mean concentrations among the cultivars with ɣ- and δ-decalactones having a concentration of approximately 180 ng·g−1 and 60 ng·g−1, respectively. Among the cultivars, “Majestic” had the highest mean concentration of ɣ-decalactone, followed by “Southern Pearl” with approximately 503 ng·g−1 and 443 ng·g−1, respectively. “Southern Pearl” and “Fairtime” also exhibited the highest average concentration of δ-decalactone. The results obtained will help provide an understanding of the distribution of the various volatile organic compounds found in Georgia-grown peach cultivars. Full article
