Yeast powder is yeast that has not been decomposed, but the nutrients in yeast extract powder have been decomposed, and the microorganisms can absorb and utilize them more quickly and efficiently, leaving less fermentation residues; current biological fermentation research basically uses yeast extract Powder and yeast extract are mostly used. Yeast powder is mainly used in traditional antibiotics and other fermentation industries.

Baking soda powder generally refers to sodium bicarbonate

Sodium bicarbonate (NaHCO?) (Sodium Bicarbonate), commonly known as baking soda. White fine crystals, less soluble in water than sodium carbonate. It is an industrial chemical with low toxicity. The solid begins to gradually decompose above 50℃ to produce sodium carbonate, carbon dioxide and water, and completely decomposes at 440℃. Sodium bicarbonate is an acid salt formed after the neutralization of a strong base and a weak acid. It is weakly alkaline when dissolved in water. This property allows it to be used as a leavening agent in food preparation. After sodium bicarbonate is used, sodium carbonate will remain. If used too much, the finished product will have an alkaline smell.
