The BBCH-scale for root and stem vegetables identifies the phenological development stages of the root and stem vegetables such as carrot, celeriac, kohlrabi, chicory, radish and swede, using the BBCH-scale.
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .
A microwave oven uses dielectric heating to cook food.. Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
A frozen meal (also called TV dinner in Canada and US), prepackaged meal, ready-made meal, [1] ready meal (UK), frozen dinner, and microwave meal portioned for an individual. A frozen meal in the United States and Canada usually consists of a type of meat, fish, or pasta for the main course, and sometimes vegetables, potatoes, and/or a dessert.
The maser led to the development of atomic clocks, which keep time using a precise microwave frequency emitted by atoms undergoing an electron transition between two energy levels. Negative resistance amplifier circuits required the invention of new nonreciprocal waveguide components, such as circulators , isolators , and directional couplers .
The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
The tables below include tabular lists for selected basic foods, compiled from United States Dept. of Agriculture sources.Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1]
