Tahini United States, sesame tahini, along with other raw nut butters, was available by 1940 in health food stores. Tahini is made from sesame seeds that are soaked in water and then crushed to separate the bran from the kernels. The crushed seeds are soaked in salt water, causing the bran to sink. The floating kernels are skimmed off the surface, toasted, and ground to produce an oily paste. Because of tahini's high oil content, many manufacturers recommend refrigeration to prevent spoilage. This is particularly true among makers of raw, organic tahini, who will often prepare their tahini at low temperatures
Carbon paste electrode solid electrodes for which basic electrochemical characteristics are comparable for almost all products from each manufacturer, each carbon paste unit is an individual, where the physical, chemical and electrochemical properties may differ from one preparation to another. For this reason each probe must be calibrated individually. While this may not be an issue in a research environment, it would be a considerable burden in production service. Carbon paste electrode A carbon-paste electrode (CPE) is made from a mixture of conducting graphite powder and a pasting liquid. These electrodes are simple to make and offer an easily renewable surface for electron
