Low-field nuclear magnetic resonance (LF NMR) technology, HSI, and hyperspectral microscopic imaging (HMI) were employed to examine the relationships between moisture content in different states, relative spectral reflectance, and spectral absorbance of “Zespri” green kiwifruit at 0, 2, 4, 6, and 8 d post-damage. Additionally, the relationship between spectral absorbance and moisture content in four states was explored. The results indicated that bruising damage disrupted the microstructure of the kiwifruit, and exacerbated the migration of free water in the vacuoles, leading to an earlier peak in the proportion of free water compared to the control group. Significant moisture absorption bands were observed at the characteristic wavelengths corresponding to hyperspectral relative reflectance and hyperspectral microscopic absorbance of damaged kiwifruit. A high negative correlation was found between hyperspectral microscopic absorbance and free water content, with linear fitting results for the top five wavelengths showing R² values exceeding 0.8940. Using the hyperspectral reflectance at the 30 most relevant characteristic wavelengths related to free water content, early discrimination analysis of damaged kiwifruit was conducted, yielding an average accuracy of 96.56 % across four model validation sets. These findings indicate that the mechanism of hyperspectral imaging in detecting bruises in kiwifruit is potentially related to free water content.

While class III peroxidases (PRXs) are recognized as crucial enzymes for lignin monomer polymerization, their specific regulatory roles in citrus granulation remain unclear. In this study, we performed a comprehensive analysis of the PRX gene family in <em>Citrus grandis</em> (pomelo) to explore their role in lignification during postharvest granulation. A total of 88 PRX genes were identified, and phylogenetic and expression pattern analyses revealed that four PRX genes—<em>CgPRX24</em>, <em>CgPRX41</em>, <em>CgPRX64</em>, and <em>CgPRX65</em>—were upregulated during the granulation process across multiple growing seasons. Further functional studies through transient overexpression in citrus fruit pericarp demonstrated that <em>CgPRX24</em>, <em>CgPRX41</em>, and <em>CgPRX65</em> significantly promoted lignification, enhancing pericarp firmness and lignin content in both pomelo and sweet orange. In contrast, <em>CgPRX64</em> had no significant effect on lignification. Conserved upregulation patterns and high sequence similarity (more than 93 %) of homologs in <em>Citrus sinensis</em> suggest evolutionary conservation of these PRXs' lignification function across citrus species. Our findings establish <em>CgPRX24/41/65</em> as phylogenetically conserved central regulators of juice sac lignification during postharvest citrus senescence.

Results showed that 1-MCP treatment effectively reduced chilling injury (CI) symptoms and maintained better fruit texture during storage.

Transcriptomic analysis demonstrated that 1-MCP regulated fruit taste by modulating multiple metabolic pathways: suppressing sucrose degradation while promoting hexose phosphorylation in sugar metabolism, enhancing organic acid synthesis through upregulation of TCA cycle-related genes, and inhibiting phenylpropanoid metabolism pathway genes to reduce polyphenolic compound accumulation. Although 1-MCP effectively maintained fruit quality and reduced bitterness development during cold storage, the decreased sweetness might also affect consumer acceptance.

It affects the fruit quality, shelf-life, and consumer satisfaction. Traditional methods for estimating fruit ripeness rely on subjective human judgment and invasive sampling techniques, which are both infeasible and time-consuming. This paper presents a novel method for estimating firmness and ripeness of fruits using their palpation motion encoded within the visual tactile scans. Moreover, these tactile scans are passed to the proposed SwishFormer model coupled with Random Forest head to predict the fruits firmness, which is later used in classifying the fruits ripeness stage. SwishFormer, unlike the existing state-of-the-art models, encompasses hardswish activation as a token mixer which allows it to generate distinctive set of features from the candidate tactile scans. These rich feature representations are then fed to the Random Forest regressor to robustly estimate the fruit firmness values and the estimated firmness values are then used in accurately predicting the ripeness level of the fruits. Apart from this, SwishFormer is extensively evaluated on the proposed dataset, containing the palpation visual tactile scans, and it outperforms state-of-the-art works by achieving 4.77%, 4.09%, 13.69%, and 4.65% better performance in terms of MSE, RMSE, R<span><math><msup><mrow></mrow><mrow><mn>2</mn></mrow></msup></math></span>, and MAE scores, while possessing 2.02 times less parameters, and 2.09 times lesser GMACs.
