Long-term storage of fruits can be achieved by means
of their special preparation by pre-treatment before
storage by electromagnetic fields of extremely low
frequency (ELF EMF). In the current study patterns of
influence of ELF EMF pre-treatment of fruits on the
effectiveness of reducing microbial contamination
during storage for the development of effective
technological modes of preparation of fruits before
storage are revealed. Qualitative and quantitative
characteristics of microbial contamination of the fruits’
surface were studied. Effective modes of fruits (apples
and pears) treatment by ELF EMF were established -
for apples: frequency - 22 Hz, current - 10 A for 40
minutes, and for pears: frequency - 26 Hz, current - 5 A
for 50 minutes, allowing to reduce to the maximum
extent the microbial contamination of their surface, and
also to reduce the loss of their weight from microbial
spoilage during storage. The terms of storage of
processed by ELF EMF fruits under refrigeration were
established - for apple varieties Idared and Golden
Delicious - within 8 months, for pear variety
Conference - for 7 months
The article analyzes the ways of ensuring a stable quality and use of biopreparations patented in Russia and abroad. The most famous biopreparations developed by Russian scientists. The analysis of literature sources and patent information has show that the development of methods for storing plant raw materials with using biological protection means is actual. Research in the field of the use of biopreparations for the processing of agricultural products is of high practical importance, since they allow a significant reduction in losses during storage. The application of biological protection treatment technologies is the most effective, environmentally safe and economical way of preparing for storage of plant raw materials
The article presents the results of studying the influence of some types of packaging materials used in conjunction with Inter Fresh’s ethylene absorber (sachets) on commercial quality and losses of Alexandria zucchini, Lyubov sweet pepper and tomatoes cv. Inkas during storage. The study was carried out using StePac Xtend bags, creating a modified atmosphere. The objects of research were stored for 14 days at a temperature of 8 – 10 °С and air relative humidity of 90±3 %. One sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions, the total weight loss is: for tomatoes – 0.3% when using Xtend bags and Inter Fresh ethylene absorbers, 1.8% when using traditional packaging materials; for zucchini – 0.4% when using Xtend bags and Inter Fresh ethylene absorbers, 1.6% when using traditional packaging materials. Losses associated with microbiological damage during storage of zucchini and tomatoes were not observed. During storage of sweet pepper microbiological spoilage took place, which, apparently, was the result of increased contamination with pathogenic microorganisms
