The long-term effects of organic farming include higher organic matter levels, increased soil biodiversity, and above-ground pest elimination.
The conservation factors were evaluated via temperature (ambient or refrigeration) and storage time (zero, seven, and 14 days). The properties that were studied belonged to three categories: physical properties (color and texture); chemical properties (moisture content, acidity, and sugars); and phenolic and antioxidant properties (anthocyanins, tannins, ABTS antioxidant activity, DPPH antioxidant activity, and total phenols).
During storage, a significant number of physical and chemical changes happened in agricultural products in general and blueberries in particular. These changes affected the quality of the berries, leading to senescence or deterioration and death.
Storage times were limited because of the tendency of blueberries to dehydrate. Oftentimes, blueberries were stored in freezers between two and four degrees Celsius and 85 to 95 percent relative humidity, for a period of up to 10 days, depending on the cultivar. It was found out that organic berries had higher acidity and lower sugar contents. (Related: Blueberries Lower High Cholesterol and Boost Cardiovascular Health.)
The study found that the antioxidant activity was not very different among cultivars, production methods, or conservation conditions. As for the phenolic compounds, tannins were higher in blueberries that were cultivated in organically. However, the most intensely blue blueberries were garnered from cultivar duke, produced in organic farming and stored under refrigeration.
Textural attributes, such as firmness, were affected by all factors at study: cultivar, production mode, and conservation. The berries from cultivar duke that were stored under refrigeration showed the highest firmness.
Berries are extremely good for your health. Here is a list of the berries, aside from blueberries, that you need to consume every day for a whole slew of health benefits.
