Abstract


Abstract

Jerusalem artichoke (Helianthus tuberosus L.) known in USA also as sunchoke, is a perennial plant, well-adapted to humid and cold climats, nonpretencious to soil and with good yield increase. The bulbs are the eatable part that grows in the ground that have certain similitudes with the potato.

The value of Jerusalem artichoke as a technical and medical vegetable is based on the chemical composition of the plant.

The bulbs of the Jerusalem artichoke harvested in autumn have been sensorially and chemically analyzed along the deposition during the cold season.

Measurements were made on the light brown variety with a slightly elongated shape. The low mass loss during depostion, the high content of reducing sugar (4.7- 6.12%) and total carbohydrates (94.27-96.18%) enable their successful use in the functional food and for the production of alcohol.
