Industrial characteristics and consumer properties of Chaenomeles Lindl. fruits

Abstract

The comparative analysis of the fruit and seed capacity of Chaenomeles Lindl., grew in the botanical garden of the Oles Honchar Dnipro National University, was carried out. It is shown that all studied taxa undergo a complete vegetation cycle. According to our observations, the duration of the growing season is as follows: the smallest in Chaenomeles japonica, the longest in C. × superba and C. maulei, the longest in C. speciosa, C. cathayensis and C. californica. Seed length in Chaenomeles plants ranged from 4.2 ± 0.10 mm (C. japonica var. maulei) to 8.5 ± 0.25 mm (C. сathayensis). Seed widths varied from 4.1 ± 0.32 mm (C. cathayensis) to 11.1 ± 0.10 mm (C. japonica var. maulei). According to the results obtained, the average number of seeds in one fruit of different Chaenomeles species differed, decreasing in the following order: C. cathayensis, C. speciosa > C. × californica > C. × superba > C. japonica > C. japonica var. maulei. Most of the Chaenomeles genus representatives were found to be in a good condition: C. japonica var. maulei vitality was estimated at 7 balls, C. japonica and C. × superba – 6 balls. This index is slightly lower for C. speciosa, C. × californica and C. cathayensis as 5 and 4 balls, respectively. It should be noted that the highest vitality was shown by C. japonica var. maulei, which was introduced in the Botanical Garden of DNU in 1955. In research, considerable attention has been paid to the antioxidant system, which is a powerful mechanism preventing the development of avalanche-free and radical peroxide reactions in living organisms. The antioxidant capacity of Chaenomeles fruits, determined in the range from 565.8 ± 15.7 (C. speciosa) to 1121.7 ± 27.5 (C. cathayensis) mg UAE / 100 g DW, can be considered quite high. The overall antioxidant capacity was highest for C. cathayensis fruits (1121.7 ± 27.5 mg AE / 100 g DW), which exceeded the indexes of other species by 1.2–2.0 times. The presence of antioxidants in raw materials and finished products provides for the prevention of their deterioration, reduction of losses, increase the shelf life and release of high quality products, retaining for a long time the characteristic features inherent in fresh, complete products. High taste qualities are characteristic of C. speciosa and C. × californica. Considering the large assortment of Chaenomeles, representatives differing in their biological, physiological and nutritional properties, we consider it promising to introduce their use in the food industry to obtain functional products with high consumer properties, namely, high content of antioxidants, catering for a variety of dishes or for exotic flavors, as well for direct consumption by the population of useful fruits with different flavors.

“…In the recent decades, the remarkable properties of Chaenomeles plants have gained wide popularity, and some species were successfully introduced to a number of European countries (Rumpunen, 2002), and to Ukraine as well (Khromykh et al, 2018;Lykholat et al, 2019). However, the ability of introduced plants to accumulate bioactive compounds and retain beneficial properties in a new environment is not fully clear.…”

STRUCTURE AND DIVERSITY OF URBAN PARK STANDS AT KRYVYI RIH ORE-MINING & METALLURGICAL DISTRICT, CENTRAL UKRAINE

“…It is widely accepted that understanding conservation targets and sustainable development of the urban forest park stands, including a full description of woody species floristic composition, dendrometric parameters and diversity and evenness indexes (Martins and Pereira, 2018). Furthermore, description and analysis of urban forest park stands through floristic and dendrometric, diversity and evenness characterization provide means to analyse the relation between woody vegetation and edaphic, topographic and human factors (Dan et al, 2016;Lykholat et al 2019a;Lykholat et al 2019b).…”
