Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods.
Caster sugar (also referred to as superfine, bar, or baker's sugar) has a larger particle size than powdered sugar, approximately half that of granulated sugar, [5] and has no added starch. It is commonly used in baking and cold mixed drinks because it dissolves faster than granulated white sugar.
Food powder (also called powdery food) is the most common format of dried solid food material that meets specific quality standards, such as moisture content, particle size, and particular morphology. [1] Common powdery food products include milk powder, tea powder, cocoa powder, coffee powder, soybean flour, wheat flour, and chili powder. [1]
Agglomerated food powder is a unit operation during which native particles are assembled to form bigger agglomerates, in which the original particle can still be distinguished. [1] Agglomeration can be achieved through processes that use liquid as a binder (wet methods) or methods that do not involve any binder (dry methods).
A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials , although the terms powder and granular are sometimes used to distinguish separate classes of material.
The formation of interactive mixtures cannot automatically be assumed, especially if smaller carrier particles [8] or a greater proportion of fine particles [9] [10] are used. If an interactive mixture is to be formed, it is necessary that enough force is exerted by the carrier particles during dry mixing to break up the aggregates formed by ...
The most widely used alum is potassium alum. It has been used since antiquity as a flocculant to clarify turbid liquids, as a mordant in dyeing, and in tanning. It is still widely used in water treatment, for medicine, for cosmetics (in deodorant), for food preparation (in baking powder and pickling), and to fire-proof paper and cloth.
A mortar and pestle is a set of two simple tools used to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The mortar (/ ˈ m ɔːr t ər /) is characteristically a bowl, typically made of hardwood, metal, ceramic, or hard stone such as granite.
