Blue Honeysuckle

In this study, we aimed to investigate the effect of processing methods and storage time on selected parameters of quality in the purees of blue honeysuckle berries. We investigated the content of bioactive compounds such as anthocyanins, L-ascorbic acid, and total polyphenols (TPs). We tested four processing methods and two varieties of blue honeysuckle berry (Lonicera caerulea L.var. Sineglaska and Volshebnica). The purees were analyzed immediately after production, and after two and four months of storage at 20 °C without exposure to light. According to our results, thermal treatment of the fruits for 5 min resulted in obtaining purees with a higher content of anthocyanins and TPs, but lower content of L-ascorbic acid. However, sieving fruits that were not thermally treated resulted in a higher content of L-ascorbic acid. Furthermore, purees prepared from the fruits of the Volshebnica cultivar were richer in bioactive compounds than that of purees prepared from the Sineglaska cultivar. In addition, the content of anthocyanins, L-ascorbic acid, and TPs decreased with storage time.

The aim of the study was to determine the influence of selected methods of preservation and storage time on the content of antioxidants in blackthorn fruit (Prunus spinosa L.). Preserved fruits were stored for 13 and 26 weeks without light at room temperature (freeze-dried and convection dried) and at –20°C (frozen samples). It was shown that both the method of preservation and the storage time had significant influence on the content of polyphenols (anthocyanins, flavonoids, total polyphenols) and antioxidant properties (Fe3+ reduction strength) of blackthorn fruit. As the storage time progressed, the anthocyanins content decreased in all preservation variants. In the case of frozen fruit after 26 weeks of storage, the content of flavonoids (by 12.5%), total polyphenols (by 48%) and the ability to reduce the iron ions were increased (by 55%). In turn, in the dried fruits after this period, the anthocyanins content, the polyphenol content and reduction strength were reduced. The highest values of the parameters evaluated after the assumed storage time has been demonstrated in lyophilizates.

Red and white wines [Grüner Veltliner white wine and Blue Limberger (Blaufränkisch) red wine (vintage 2013)] were enriched with lignan hydroxymatairesinol originated from spruce knots. These spruce knots with removed resin were extracted with ethyl alcohol of agricultural origin. Ethanol extracts of lignans were then used to enrich wine sorts. Enriched wines were stored for 13 months. At 2, 6, and 13 months, samples were taken and subjected to a variety of analyses and sensory evaluations. Analyses included 7-hydroxymatairesinol and alpha-conidendrin lignan content, antioxidant activity (as determined by FRAP), total polyphenols, and sensory evaluation. The obtained data were evaluated using the analysis of variance to determine which factors e.g. wine type, quantity of added lignan extracts, additional sugar, method of preservation, and storage time had the most significant influence on lignan content, antioxidant activity and polyphenol content. In all cases the lignan content in the wines was significantly influenced by the addition of lignan extracts. After one year of storage, lignan contents changed only moderately and added lignans were stable in stored wines. Total polyphenol content in wines and the antioxidant activity of wines were significantly influenced by the type of wine (i.e., red or white). The presented method of wine enrichment with lignans opens the door for the production of extra quality wines.

Blue Honeysuckle

The aim of study was to compare yield, fruit quality, chemical composition and fruits colour of berries of two blue honeysuckle(Lonicera caerulea L.) cultivars of Polish bred ‘Wojtek’ and ‘Brązowa’ collected at the beginning and at the end of harvest season,respectively. On average, ‘Wojtek’ yielded 1565 g per bush, whereas ‘Brązowa’ 1941 g. During the fruit ripening process, considerablechanges were found in the fruit colour. Fruits of both cultivars became darker and their colour changed from green and yellow to redand blue. With the changes in fruit colour, considerable changes in firmness also occurred. Fruit ripening reduced fruit firmness andpuncture resistance. For both genotypes, the berries of late harvest were bigger and richer in soluble solids and total polyphenol, however,they showed decreased firmness, lower acidity, and L-ascorbic acid content. Nevertheless the time of harvest, ‘Wojtek’ berries surpassed‘Brązowa’ fruit regarding soluble solids, titratable acidity and L-ascorbic acid content (for late-crop berries of both cultivars 14.1>12.6%,3.4>2.7 g citric acid 100 g1, and 76>56 mg 100 mL-1. Further, ‘Wojtek’ berries showed higher total polyphenol content (149.30 and183.66 mg∙100 g-1, for early and late ripening fruit, respectively) compared to that of ‘Brązowa’ (125.51 and 175.67 mg 100 g-1). Amongphenolics, anthocyanins made the substantial group ranging from 94.47 mg 100 g-1 (‘Brązowa’ berries of early harvest) to 141.96 mg 100g-1 (late ‘Wojtek’ fruit).

<p>The research was conducted to investigate the effect of soaking meat of Peranakan Ongole cattle with ascorbic acid and storage duration at 50C on physical quality of meat. The experiment was done in Complete Randomised Design by factorial 3 x 3. First factor was ascorbic acid with 3 levels (0%, 5%, 1%), and second factor is storage duration with 3 levels (0, 5, and 6 days). Variables that were measured: tenderness, cooking loss, water holding capacity and pH. Data were analyzed by variance analysis and the significant result were tested by Duncan’s test. Tenderness average for ascorbic acid ranging between 1,60 – 1,62 kg/cm2, and for storage duration was increased from 1,83 to 1,38 kg/cm2. Cooking loss average for ascorbat acid ranged from 43,33 to 44,89%, and for storage duration increased from 40,00 to 47,00%. Water holding capacity average for ascorbic acid ranging between 32,88 – 33,65%, but for storage duration decreased from 34,61 to 32,32%. The pH average for ascorbic acid ranging from 5,99 to 6,16, and increased for storage duration from 6,43 to 5,84. It can be concluded that physical quality of beef cattle was not affected<br />bay ascorbic acid up to 1%, but was significantly decreased by storage duration (p&lt;0,05).</p><p>Key words: Pernakan Ongole meat, ascorbat acid, storage time</p>
