QUALITY OF GARDEN STRAWBERRY FRUIT GROWN UNDER CONDITIONS OF TECHNOGENIC POLLUTION
The quality of fruit of garden strawberries grown on technogenically contaminated soils has been assessed. The highest level of copper and zinc in the fruit was recorded after broadcasting the recommended quantity of the fertiliser N90P60K30. Introduction of the sorbent ameliorant GREENODIN GRAY red...

As a result, the Olviya berries had the longest shelf life – 7 days, when stored in cooling chambers at 0.5°С and relative air humidity 90%.

The resulting Olviya berries are resistant to diseases and phytopathogenic damage during storage, have high nutritional value, and are less likely to accumulate ecotoxicants.

The content of nitrates and heavy metals in the berries did not exceed the maximum permissible concentration.https://journals.onaft.edu.ua/index.php/foodtech/article/view/1905garden strawberrycultivarheavy metalsnutritional valueenvironmentally safe product |
