Ground beef already formed into patties or separated into smaller quantities take less time and defrost quicker. For instance, 1/2-inch (1.25-cm) ground beef patties that were frozen separately usually take about 10 hours to defrost.
Gelatin is a protein substance used to thicken liquids. It does not have a color, smell, or taste. It comes from boiling animal tissues such as beef bones, cartilage, tendons, and pig skin. Gelatin is used in many kinds of food products and drug and supplement products.
It is made by boiling the bones, skin, tendons, and hooves of animals. (It can also be found in some organs.) There are vegetarian alternatives to gelatin (they come from seaweed), but unless the ingredients list specifically says that it is vegetarian or plant-derived gelatin, it's made from body parts.ollagen is found in multiple animal tissues, but is mostly extracted from cow or pig's skin and bones. another source of gelatin is fish bones, so depending on what type of vegetarian you/your friend are/is, it might be fine for you.
