PROSPECTS OF USING NEW VARIETIES OF APPLE TREES AS A RAW MATERIAL FOR JUICE PRODUCTION

Abstract

Fruit suitability of apple cultivars of new generation of VNIISPK breeding, which have immunity to scab (Vf, Vm), triploidy (3x), and columnarity (Co) as well as combine scab immunity and columnarity (Vf + Co), scab immunity and triploidy (Vf + 3x) in one genome, was studied for the purpose of juice production. The technological estimation was done according to the following indicators: juice output, contents of soluble dry substances, sugars, organic acids, P-active compounds in juice and organoleptic qualities of juice. The new cultivars showed a high level of the technological indicators important for juice production. This makes them promising in the production of natural juice directly pressed for consumption and for further concentration. Apple cultivars, such as Bolotovskoye, Osipovskoye, Spasskoye, Priokskoye and Bezhin Lug, are suitable for the production of baby food since the juice of these cultivars meet the requirements TR № 178-FZ in the contents of soluble dry substances and titrate acids for baby food. The technology development of innovational cultivars cultivation in raw orchards could significantly allow solving the problem of the shortage of raw materials in the national juice industry.
