because the FDA considers any product that has less than 5 calories per serving to be calorie free.
因?yàn)镕DA認(rèn)定，任何含有5卡路里以下的產(chǎn)品都是不含卡路里的產(chǎn)品，
Aspartame is generally shelf stable
阿斯巴甜一般能夠貯存很長(zhǎng)時(shí)間，

This product is shelf stable but also having limited degregation when applied to heat.
這種產(chǎn)品可以儲(chǔ)存很長(zhǎng)時(shí)間，但是遇熱也會(huì)變質(zhì)，
Saccharin is very inexpensive which has caused increase in its use.

盡管蔗糖素是一種雙糖
it is poorly absorbed so its considered non nutritive.

Succralose has a good shelf life and is heat stable in cooking and baking.
蔗糖素可以長(zhǎng)期儲(chǔ)存，在烹飪過程中的耐熱性也極好
In 1998 the FDA approved it for use as a tabletop sweetener,
