Yes, it has been approved as a safe ingredient by the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

FDA
Glyceryl monostearate is a generally recognized as safe (GRAS) ingredient when used in food with no limitation other than current good manufacturing practice (5). And also, it is GRAS when used in feed. (6)

EFSA

Glyceryl monostearate (E471) belongs to Mono- and Diglycerides of fatty acids and listed in Commission Regulation (EU) No 231/2012 as an authorised food additive and categorized in “Additives other than colours and sweeteners” (7).

Tetra Sodium Pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer.

Uses: Decreasing blood phosphate levels can help keep your bones strong, prevent unsafe buildup of minerals in your body, and possibly decrease the risk of heart disease and strokes that can result from high phosphate levels. Calcium acetate is a natural mineral that works by holding onto phosphate from the diet so that it can pass out of your body.
PhosLo (Calcium Acetate) is used for reducing phosphate levels in late-stage kidney failure. One of the dangers associated with kidney disease is the development of an overabundance of phosphate in the body. Too much phosphate in the blood stream can result in weak bones, an increased risk for heart attack or stroke, or a build-up of minerals in the body to levels that are unsafe. PhosLo (Calcium Acetate) works by preventing ingested phosphate from being absorbed into the blood stream.

Yes, when used as a food additive, it is safe and almost has no side effects. The U.S. Food and Drug Administration (FDA) claimed calcium acetate is GRAS, and European Food Safety Authority (EFSA) pointed out acetates are normal components of the diet of humans and are fully metabolized (2), the Joint FAO/WHO Expert Committee on Food Additives (JECFA) also approved its safety earlier.

FDA
Calcium acetate is generally recognized as safe (GRAS) that can be used as a firming agent, pH control agent, sequestrant, stabilizer, thickener, and texturizer in food. The following food list may contain it and with the maximum usage (3):

Baked goods 0.2%
Cheese 0.02%
Gelatins, puddings, and fillings 0.2%
Sweet sauces, toppings, and syrups 0.15%
Other food categories 0.0001%
EFSA

Canned or bottled fruit and vegetables
Bread
Prepacked meat
Processed cereal-based foods and baby foods, only for pH adjustment
JECFA
