“…preventing microbial access and development[53]. The content of polyphenolic compounds in apples also depends on the agricultural and climatic conditions during growth as well as on storage conditions[54].The TPC obtained in this work is comparable to the data provided by previous studies: 221-476 mg/100g d.m. in 'Jonagold'[23], 564-748 mg/100 g d.m.…”

The study assessed the changes in the quality and physical and chemical parameters of apples of four cultivars (‘Gala’, ‘Idared’, ‘Topaz’, ‘Red Prince’) subjected to mechanical vibrations during transport under model conditions and after storage (shelf-life). Quality changes in apples were evaluated based on skin and flesh colour, total soluble solids, dry matter, firmness, titratable acidity, pH value, total polyphenol content and antioxidant capacity. The applied vibrations at a frequency of 28 Hz caused changes in the above parameters, which were visible also after storage and depended on cultivar, but did not show any clear trend or direction. Skin colour varied whereas flesh colour remained stable. Vibrations resulted in a decrease in firmness. The greatest stability of quality parameters, the highest content of bioactive compounds and the highest antioxidant capacity were observed for ‘Red Prince’ and ‘Topaz’ apples – this refers to the control and treated samples before and after storage. However, total polyphenol content and antioxidant capacity increased in all studied cultivars as a result of vibrations and storage, which suggests that 28 Hz mechanical vibrations and short-term cold storage did not reduce the health promoting potential of the apples.

“…The literature reports both increase and decrease in TPC in fruit after harvest. Polyphenol content was observed to have increased in 'Auksis' apples cold-stored in normal and controlled atmosphere (ultra-low oxygen), including after applying 1-MCP[54]. The same was noted during the storage of e.g.…”

“…According Sethi et al, antioxidant activity strongly correlated with the amount of phenolic compounds [ 33 ]. The content of phenolics, and therefore antioxidant activity, can be influenced by various factors such as pre-harvest meteorological conditions, cultural practices, maturity, and harvesting methods [ 34 , 35 ]. DPPH scavenging activity decreased from 44–20 mM Trolox (equivalent) g −1 (depending on variety) to 11.7–3.6 mM Trolox g −1 (depending on variety) during fruit ripening, while ABTS scavenging activity from 4.5–2.6 mM Trolox g −1 to 1.4–0.9 mM Trolox g −1 [ 35 ].…”

Global demand for food is increasing each year, but the area of land suitable for farming is limited. Thus, there is a need to grow not only larger quantities of food but also higher quality food products in the same area. This study aimed to evaluate the influence of rootstock and high-density orchards on cv. Auksis fruit quality. Two rootstocks were selected for this experiment, P 22 super dwarfing and P 60 dwarfing. Apple trees cv. Auksis were planted in the year 2001 in single rows spaced 1.00 m, 0.75 m, and 0.50 m, apart with 3 m between rows. High-density planting and rootstock combination was found to have no significant effect on sugar accumulation and most of the elements in apple fruits. However, super dwarfing P 22 rootstock accumulated significantly higher (up to 45%) content of organic acids and up to 33%–44% lower DPPH free radical scavering activity compared to P 60 dwarfing rootstock. After summarizing the obtained results, apples which accumulated the most antioxidants (according to the activity of phenolic compounds, DPPH• and ABTS•), magnesium, and potassium were collected from cv. Auksis apple trees which was grafted on super dwarfing P 22 rootstock and planted at 3 × 0.75 m distances.

A technology has been developed for the production of edible packaging based on applesauce with the addition of dried fruit and vegetable raw materials. As a result of research, a technology was developed for the production of edible glasses based on applesauce with the addition of dried apples, apricots, cranberries, bell peppers, tomatoes, carrots, and beets. A comparative assessment of the organoleptic and physico-chemical parameters of edible glasses based on applesauce with the addition of dried fruit and vegetable raw materials. Organoleptic indicators, humidity, water absorption, resistance to model liquids (distilled water with a temperature of 20–25 °C; distilled water with an initial temperature of 90–95 °C; 5 % aqueous solution of sodium chloride with a temperature of 20–25 °C; 5 % aqueous citric acid solution with a temperature of 20–25 °C), microscopic examination of the surface. Thus, as a result of a study of the organoleptic and physico-chemical parameters of edible packaging based on apple raw materials with the addition of dried fruit and vegetable raw materials, it was found that the most optimal physico-chemical indicators and mechanical properties of the glass are observed at the highest degree of grinding of dried fruit / vegetable additives and increase the degree of coverage of the surface area of the edible glass with the additive.
