In the present study, in the first step, the effect of Aloe vera gel (75% v/v) coating containing different concentrations of hemp seed oil (1-5% v/v) on some physicochemical properties of cherry tomatoes during storage at room temperature was investigated. The results revealed the ability of hemp seed oil to improve the physicochemical properties of cherry tomatoes during storage, although no significant difference was observed between 3 and 5% levels of hemp seed oil (p> 0.05). Slope change in the ripening index trend occurred for A. vera gel (75% v/v) coated sample on day 12 and for A. vera gel containing 3% hemp seed oil coated sample on day 16. Using an image processing system, the changes of the coated samples were evaluated based on the color statistical and color texture features extracted from the images and were graded through different procedures. The results showed that the principal component analysis (PCA) and artificial neural network (ANN) methods were able to divide the cherry tomatoes into intact and blemished grades which the ANN method was graded samples using color texture features with higher accuracy (97.41%). The adaptive neuro-fuzzy inference system (ANFIS) method had higher diagnostic power than the other two methods and was able to grade the samples into three grades including intact, grade 2 and unusable with accuracy of 98.96%.

Appearance, taste, and bioactive compounds of `Lane Late´ orange fruits on three sub-standard or semi-dwarfing rootstocks [Forner-Alcaide no. 5, Forner-Alcaide no. 13 and Forner-Alcaide no. 41] were evaluated in Spain against three more traditional rootstocks [Carrizo citrange, Citrus macrophylla and `Cleopatra´ mandarin]. Different harvesting times were identified per rootstock. The most suitable harvesting time for `Lane Late´ orange fruits on `Cleopatra´ mandarin, Forner-Alcaide no. 13 or Forner-Alcaide no. 5 was March, between one and two months later than Citrus macrophylla, Carrizo citrange or Forner-Alcaide no. 41, more relevant date for this late-season navel orange. Despite harvesting `Lane Late´ orange fruits on the most suitable date for each rootstock, significant differences in overall fruit quality were observed among them. Thus, Citrus macrophylla induced the largest size but also the lowest organoleptic quality, Carrizo citrange induced the lowest bioactive compounds content, while Forner-Alcaide no. 5, Forner-Alcaide no. 13 and `Cleopatra´ mandarin induced the highest internal quality. Lane Late orange fruits on Forner-Alcaide no. 41 showed an intermediate behavior.

This study aimed to evaluate the impact of dipping solutions [Moringa Leaf Extract 5% (MLE), Olive Leaf Extract 5% (OLE) and Calcium Chloride 5% (CaCl₂)] on fruit quality of two peach (Prunus persica L. Batsch) cultivars (Blanvio 10 and Plagold 15). The treatments consisted of dipping fruits for 5 min in the corresponding solution followed by 30 minutes drying at room temperature. Then, fruits were stored at 5°C and 95% relative humidity for 2 and 4 weeks of cold storage followed by 2 days at room temperature. Physicochemical traits, antioxidant compounds, sugar content and chilling injury symptoms were analyzed. There were significant improvements in fruits storability resulting from the CaCl₂, MLE (5%) and OLE (5%) dipping solutions. These treatments improved firmness, maintained the Soluble Solids Content, and increased the ripening index (SSC/TA). The lowest fruit weight loss was observed in the OLE treatment, whereas the untreated fruits showed the highest loss. The flavonoids, total phenolics, vitamin C and antioxidant capacity showed a gradual decrease during the storage periods. Mealiness and internal browning were the major chilling injury symptoms observed in the two peach cultivars after 4 weeks of cold storage. The applied treatments were efficient and delayed the presence of chilling injury symptoms and fruit decay during the two cold storage periods.
