Once the tomatoes have reached mature size, you can bring them inside to finish ripening. As a result, the fruit can stay in a mature green phase for quite some time. At these temperatures, lycopene and carotene, pigments responsible for giving the fruit their typical orange to red appearance cannot be produced. When temperatures exceed 85 degrees to 90 degrees F, the ripening process slows significantly or even stops. The optimum temperature for ripening tomatoes is 70 to 75☏. Cornell University Cooperative Extension notes: While tomatoes are generally heat loving plants, roasting heat is a problem. This year (2015), many area of the country are running into the opposite temperature extreme – it's too hot for the tomatoes to ripen.

Lycopene is a powerful antioxidant that may help protect cells from damage. Some people also use lycopene for cataracts and asthma. ![]() Lycopene is also used for treating human papilloma virus (HPV) infection, which is a major cause of uterine cancer. People take lycopene for preventing heart disease, “hardening of the arteries” (atherosclerosis) and cancer of the prostate, breast, lung, bladder, ovaries, colon, and pancreas. The lycopene in supplements is about as easy for the body to use as lycopene found in food. Processing raw tomatoes using heat (in the making of tomato juice, tomato paste or ketchup, for example) actually changes the lycopene in the raw product into a form that is easier for the body to use. One cup (240 mL) of tomato juice provides about 23 mg of lycopene. In North America, 85% of dietary lycopene comes from tomato products such as tomato juice or paste. It is found in particularly high amounts in tomatoes and tomato products. Lycopene is found in watermelons, pink grapefruits, apricots, and pink guavas. It is one of a number of pigments called carotenoids. ![]() Lycopene is a naturally occurring chemical that gives fruits and vegetables a red color. What is lycopene?
