| Quality of cloudy organic apple juice processed by rack-and-frame press (RFP), water press (WP) or belt press (BP) was evaluated in terms of sensory properties and instrumentally measured colour, content of ascorbic acid (AsA), total soluble solids (TSS), titratable acidity (TA), polyphenols and total antioxidant capacity (TAC). ‘Cortland’, ‘Krista’, ‘Krameri tuvi~oun’ and ‘Talvenauding’ apples from Estonia were separately processed into juice by RFP, WP and BP. Juice was pasteurized at 85 �C. Pressing methods had a significant effect on juice quality. RFP-juices had the lowest TAC and content of health-beneficial polyphenols (chlorogenic acid, (�) epicatechin, (þ)catechin, procyanidin B2). BP-juices had the highest content of these polyphenols,... |

| The aim was to determine the differences in mineral composition and sensory properties of cloudy apple juice depending on apple cultivation system. Three indigenous Estonian cultivars were chosen on condition that the same cultivars would be grown in organic and conventional orchards at the same geographical location. ’Krameri tuviõun’ and ’Talvenauding’ apples were harvested from old (over 30 years) low maintenance orchard and ‘Krista’ apples from 10-years old experimental orchard. 100 kg of apples per cultivar and cultivation system were stored at +3±2°C for two months and then pressed into juice using Lancman waterpress. Total soluble solids (TSS), titratable acidity (TA) and content of P, K, Ca and Mg were determined from apples and from juice.... |
