Quality Attributes of Chitosan-Coated Cornelian Cherry (Cornus mas L.) Fruits under Different Storage Temperatures

Temperature is the dominant environmental stimulus that influences the postharvest quality, visual appearance, and nutritional content of fruits. Temperature hastens fruit ripening and senescence by the impact on respiration rate and the acceleration of metabolic reactions. This study was conducted to select the optimized temperature for preserving the quality-related traits and antioxidant potential of cornelian cherry fruits after harvest. The fruits were treated with 1% chitosan and then kept under 0, 5, 10, and 21 °C for 21 days. The results revealed that fruits kept under lower than room temperature (21 °C) better retained antioxidant capacity and had higher levels of phenolics, flavonoids, and anthocyanins and even higher antioxidant enzyme activity, hence attaining prolonged postharvest life. Considering the quantity attributes and the shelf life, the temperature of choice was 0 °C. Zero temperature was also the best to keep the antioxidant capacity of cornelian cherry fruits. Overall, the results showed that low temperature and chitosan pretreatment provide an efficient method for maintaining the nutritional quality and antioxidant capacity of cornelian cherry fruits during storage time.

Abstract Cornelian cherry (Cornus mas L.) is a plant growing in Central and Eastern Europe. Its fruits are a rich source of anthocyanins, flavonoids and iridoids. Among the iridoids, loganic acid is the most prevalent. The study aimed to examine the relation between loganic acid content, antioxidant capacity and hypoglycaemic effect in vivo for three Polish cultivars of C. mas. All tested cultivars strongly inhibited α-glucosidase and had similar amounts of highly bioabsorbable loganic acid. The loganic acid content was similar for each cultivar tested, while the cultivars differed in content of flavonoids and anthocyanins. The highest antioxidant potential was observed in the fruits of cv. Szafer, and the highest α-glucosidase inhibitor was cv. P5. A statistical analysis has shown that hypoglycaemic properties are prevalently driven by anthocyanin content and the antioxidant capacity, especially ferric-reducing ability partially based on loganic acid.

A number of selected cornelian cherry wild genotypes were investigated regarding antioxidant capacity, total phenols, total flavonoids and colour component. The total phenolic, total flavonoids and antioxidant activity of methanol extract of cornelian cherry fruits were determined using Folin-Ciocalteu, colorimetric and DPPH methods, respectively. Total phenolic content ranged from 163.69 (S1) to 359.28 (H2) mg GAE 100 g-1 FW. Genotypes H2 and H3 had the highest total phenolic content (359.28 and 343.50 mg GAE 100 g-1 FW, respectively), total flavonoids (54.26 and 64.48 mg QE 100 g-1 FW, respectively) and antioxidant capacity (2.39 and 2.71 mmolTrolox100g-1 FW, respectively). Significant differences of yellow/blue color component (b*), red/ green (a*) color component, values of lightness (L*) and chroma (C) were obtained for extracts from fruits. The present study shows the potential of certain cornelian cherry genotypes as valuable source of natural antioxidants and gene stock for breeding programs.

The comparison of the antioxidant activity of the studied forest fruits emphasized a hierarchy of the antioxidant capacity in rosehip, blackthorn, lingonberry and cornelian cherry. The purpose of the study was to investigate the antioxidant capacity and nutritional value of rosehip, blackthorn, lingonberry and cornelian cherry. In the current study, the FT-IR spectroscopy technique was applied to detect molecular components in forest fruits samples. Antioxidant capacity was evaluated with photochemical assay as well as humidity, protein, fibre, lipid and carbohydrate content. The FT-IR results revealed the presence of different bio-active compounds in berries such as flavonoids, tannins, sugars, acids, proanthocyanidins, carotenoids, citric metabolites and others. The highest antioxidant capacity was observed in rosehip 105.67±1.38 and blackthorn 49.89±1.92 (μg/mg equivalent ascorbic acid). Regarding nutritional parameters, rosehip showed the most increased content of protein displaying average values of 1.60, carbohydrates 38.20 and fibre 24.10 (g/100 g/sample). These results can provide useful information providing a research interest for the identification of new molecular compounds from Romanian flora samples. ********* In press - Online First.

Tamarillo (Cyphomandra betacea L.) fruits, grown in the Venezuela Andes farms, were harvested at mature-green stage, graded, selected, washed, and transported to the posharvest lab. for analysis. Fruits were stored into plastic containers in storage rooms at (5, 10, and 15 °C for 3 weeks. The soluble solid concentration (SSC), pH, tritatable acidity (TA), ratio SSC/TA, color: L*, Hue, Chroma, color index (a+b)/L × 100, texture, and fresh fruit weight loss (FFWL) in pulp extract and in the whole fruit were determined on the first day of harvest and at the end of each storage week. These parameters ranged as follows: SSC: 7.92–8.84%, pH: 4.06–4.35, TA: 1.14%–1.21% (expressed as citric acid), SSC/TA: 1.58–1.75, Chroma 42.72—45.54, FFWL: 0.83% at the second storage day to 4.39% at the 3rd storage week. Also, FFWL was 1.03%–1.40% for 10 and 15 °C, respectively. Fruits stored at the highest temperature increased pH values, the TA decreased with stored time, the Chroma and FFWL values increased with the increasing temperature and storage time.

To investigate the variation in the phytonutrients of Cornelian cherry (Cornus mas L.), fruit was harvested at the blush (S1), red (S2), and ripe (S3) stages from five genotypes maintained at the Secrest Arboretum, Wooster, Ohio. The S1-S3 samples were characterized for color reflectance and then frozen at –28 °C. After storage, samples were analyzed for dry weight (DW), total soluble solids (TSS), sugars (FRU + GLU), organic acids (ORG), total phenols (PHE), total anthocyanins (ACY), individual anthocyanins (IA), hydroyzable tannins (HT), and antioxidant capacity (FRAP and ABTS). From S1 to S3, DW and TSS increased by 24% and 21%, respectively, and L, hue angle, and chroma values decreased. On a DW basis, all analytical parameters were significantly influenced by genotype and stage. The ACY levels rose 7-fold during ripening, but PHE contents declined by 10%. In ripe fruit, HT comprised the bulk of the PHE constituents, whereas ACY accounted for only 7.6% of PHE levels. Variability among genotypes was moderate for all ripe fruit parameters but ACY. Ripe fruit varied little in color parameters and ACY (fwb) and IA (fwb) were not significantly different among cultivars. The Cy 3-gal and pel 3-gal levels were negatively correlated. Antioxidant capacity declined 16% to 18% during ripening. Ripe fruit FRAP and ABTS values were higher than those reported for most fruits, averaging 596 ± 85 and 629 ± 85 μmol TE eq./gDW, respectively. ABTS and FRAP values were highly correlated with each other and with PHE and HT contents, but were loosely and negatively related to ACY levels. Considering our limited sample size, we concluded that the phytonutrient capacity of cornelian cherry is substantial, predominantly associated with tannins and moderately variable among genotypes.
