Physico-chemical and technological studies on sugar beet roots.

The morphological and chemical characteristics of ten varieties of sugar beet roots were evaluated during the season of 1996-1997. The best morphological characteristics were found in Top, Ito and Pamela varieties. The highest expected technological yield of sugar was found in Pamela and Top. The chemical constituents of different varieties of sugar-beet roots showed significant differences. The suitability of sugar beet juice for preparing beet syrup as a new product was also evaluated and compared with sugar cane syrup. Purified beet-syrups concentrated under vacuum or under atmospheric pressure showed more stability during storage than sugar cane syrup. The effect of storage conditions (at cold storage and at room temperature) and packaging materials (glass and polyethylene high-density bottles) on properties of beet-syrup and sugar cane syrup were also studied.
