The interaction of temperature and relative humidity affects the main aromatic components in postharvest Torreya grandis nuts
Abstract
The postharvest ripening stage is necessary for Torreya grandis (T. grandis) nuts to complete aromatic synthesis, which requires appropriate temperature and relative humidity (RH). Currently, scarce information is available regarding the changes in aroma profiles in T. grandis nuts and the relationship with their response to different environmental conditions. Therefore, the interaction of temperature (20 °C or 30 °C) and relative humidity (70% RH or 90% RH) was investigated on aromatic substances after harvest. The results showed that 56 aromatic components were detected by a gas chromatography-mass spectrometer (GC-MS) and mainly divided into five categories, among which terpenes were the most abundant (56.2-86.7%). Principal component analysis (PCA) showed that both temperature and humidity can affect the aroma composition, and terpenes were mainly influenced by humidity. Specifically, d-limonene occupied the largest proportion of terpenes (63.0-90.8%) and was significantly upregulated by high humidity.

The composition and extracted yield of essential oils depend on species, soil composition, plant organ, age, cycle stage, selected extraction method, and conditions of extraction.
“Various authors have reported that the composition and extracted yield of EOs depends on the species, soil composition, plant organ (aerial parts, inflorescence, or roots), age, cycle stage, selected extraction method, and conditions of extraction [2,5,6,7,8,9,10,11,12,13,14,15,16,17].”

Storage conditions impact the composition of essential oil, mainly due to duration, temperature, and relative humidity of storage, causing generation or degradation of certain components.
“Research by Hu et al. [6] notes that the storage conditions also impact the composition of EO, mainly due to the duration, temperature, and relative humidity of the storage, causing the generation or degradation of certain components [6,18].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
