The Rise of Canned Tomatoes

Canned tomatoes are a cornerstone of global cuisine, offering year-round access to summer-ripe flavors. First commercially canned in 1847 by Harrison Woodhull Crosby in New Jersey, they revolutionized food preservation. Today, over 40 million metric tons of tomatoes are processed annually worldwide, with Italy, the U.S., and China leading production

Concentration Processes: From Field to Can

Step 1: Thermal Vacuum Evaporation

Industrial evaporators remove 90% water at 70°C to preserve lycopene.

Energy Efficiency: Modern triple-effect evaporators use 35% less steam than single-stage systems.

Step 2: Aseptic Concentration

High-Temperature Short-Time (HTST) processing at 125°C for 30 seconds maintains:

Color (Hunter Lab value L* > 25)

Vitamin C retention (>80%)

Step 3: Rheology Control

Pectinase enzymes (0.01-0.05% w/w) adjust viscosity without additives.

Cardiovascular Protection

Lycopene: 75mg per 100g paste vs 3mg in fresh tomatoes

Study: Daily 2 tbsp reduces LDL oxidation by 13%

Cancer Prevention

Mechanism: Apoptosis induction in prostate cancer cells

Synergy: Combined with broccoli sprouts → 40% higher sulforaphane absorption

Skin Health

UV Protection: 16% reduction in erythema with 12-week supplementation
