"What is the sweetest strawberry?"

Since March 2019 strawberry on iFarm vertical farms were cultivated using 4 ways: aeroponics (1), low-volume hydroponics with drip irrigation on coconut substrate (2) and on coconut mats (3) and low-volume hydroponics with watering using the method of periodic flooding (4). For the research we used several berries from each bushes and purchased Turkish berries in a store.

Strawberry contains 9 major types of sugar. Among them are sucrose, glucose, fructose, sorbitol, xylose, maltose, galactose, raffinose and lactose. These sugars are simple carbohydrates, which mean they are the main suppliers of energy to the human body. Although the energy coefficient of sugars is lower than that of fats, a man daily eat large amount of carbohydrates and gets 50-60% of the required calories with them.

"We did a research of three main sugars (sucrose, fructose and glucose), as their degree of sweetness is higher than that of all the others. The research was made using the method of high performance liquid chromatography, which separates complex mixtures of substances and is used in analytical chemistry to determine the concentration of organic substances in various objects", the company says.
