The boiling temperature of nitrogen is â195.8 Â°C (â320.4 Â°F), about 13 Â°C (â23 Â°F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen.
Acidic foods like citrus fruits can stimulate acid production and increase heartburn. Avoid oranges, grapefruit, lemons and their juice. Like citrus fruits, tomatoes and products made from tomatoes (tomato sauce and paste, tomato juice) can stimulate the stomach to produce more acid.
While unopened tomato juice can last several weeks or months, once opened, contact with the air eventually leads to spoilage. Mold and other potentially harmful spoilage microorganisms can cause you to become very ill if you ingest them in spoiled juice; plus, the juice will taste awful. When making fresh tomato juice at home, only used freshly washed tomatoes that are free from any bruises or mold.
