Effect of Dehydrating Process of Tomato in Lycopene Stability

Level of Isomerization

Dehydrating Process Total Lycopene (%)

None (fresh tomato) 75.5 0

Osmotic treatment (25°C in 65° Brix sucrose solution for 4 h) 75.5 0

Osmotic-vacuum drieda 73.7 6.5

a Processing is sequential: first, osmosis is carried out up to 50 to 55% of moisture, followed by vacuum drying up to 3 to 4%.
