Abstract
The potato processing industry establishes strict processing requirements to obtain the highest quality products at reasonable prices.
A cultivar with a starch content between 17 and 19% is preferred for chips because a lower starch content in the tubers leads to a high oil uptake during frying and reduced shelf life.
The following cultivars were processed into chips in the laboratory: ‘Opal’, ‘Hermes’, ‘Milenium’, ‘Pirol’ and ‘Verdi’, cultivars harvested from the experimental field in four fertilization variants.
The best chip yield was obtained from ‘Pirol’ with 29.41% followed by ‘Verdi’ with 29.27%. The best results for all the parameters analyzed were recorded in the N:P:K treatment applied as 211:120:249 kg ha‑1 active substance where the chip yield was 30.98%, roasting time 6’28” and starch content 19.64% in tubers.
To ensure higher processing yields in chips the cultivar used and fertilization ratio are the determining factors.
