Abstract
The object of this research is the technological process of refrigerated storage of fruit products. In order to reduce the level of losses during normal refrigeration, a technological audit is carried out to solve this problem by applying antioxidant compositions for post-harvest treatment of fruits. The aim of research is development of a new antioxidant composition and optimization of its composition. The use of this composition for post-harvest treatment of fruits contributes to the extension of their shelf life and the reduction of the level of daily loss. The treatment with antioxidant compositions (AOC) was performed in storage facilities by immersing them in pre-prepared working solutions. Exposure – 10 seconds. The fruit was dried by ventilation. Options for treatment: K – control, option 1 – DL – a mixture of dimethyl sulfoxide, ionol and lecithin. The following concentrations of active substances were studied: distinol 0–0.048 %, lecithin 0–6 %. The effectiveness of exposure to various concentrations of active substances is determined by the average level of daily loss of fruit during storage, consisting of the sum of mass losses and losses caused by microbiological diseases and functional disorders, referred to the number of days of storage. The following concentrations of active substances in the developed antioxidant composition are established by optimization: apple and pear fruits storage – distinol concentration is 0.041...0.042 %, the lecithin concentration is 2.9 %. Plum fruits storage, respectively: distinol – 0.022 %, lecithin – 3.4 %.
Highlights
Fruit products due to their high biological value and functional properties should be an obligatory component of the human diet throughout the year
Among the main factors contributing to this situation in the field of fruit storage are the lack of modern production facilities for storing and use of too expensive, and sometimes very complex and unsustainable storage technologies [4,5,6]
To find ways to eliminate these problems, a technological audit is conducted, which aimed to investigate the possibility of using antioxidant compositions for fruit treatment before further storage
Summary
Fruit products due to their high biological value and functional properties should be an obligatory component of the human diet throughout the year. Among the main factors contributing to this situation in the field of fruit storage are the lack of modern production facilities for storing and use of too expensive, and sometimes very complex and unsustainable storage technologies [4,5,6]. In this regard, studies devoted to the search for ways to improve existing storage technologies, with the aim of providing the population with fresh and quality fruit products throughout the year, are relevant
