Baidu said: Honey is a natural sweet substance that bees collect nectar, secretions or honeydew from plants, combine it with their own secretions, and fully brew it. In terms of its main components, honey is actually a supersaturated sugar solution. What we call honey concentration or the often mentioned "degree" in daily life actually refers to the Baume degree of honey. Baume is another unit of honey specific gravity, while the exact meaning of honey concentration refers to the percentage of soluble solids in honey. Since the higher the concentration of honey, the greater the specific gravity, and the concentration is directly proportional to the Baume degree. Therefore, in practical work, people refer to the Baume degree of honey as the concentration of honey, which has become a habitual term. In fact, there is a difference between the two and they are not the same concept. The Baume meter is measured with a Baume meter, which is a type of hydrometer and a glass float meter. It was founded by the Frenchman Baumè, so the Baume meter can be recorded as "°Bè". The Baume degree of honey is most affected by temperature and changes with temperature. When the temperature rises, the Baume degree of honey becomes smaller; when the temperature drops, the Baume degree of honey becomes larger. In order to unify the comparison standard, the international standard stipulates that 20°C is used as the standard temperature. Any Baume degree measured not at this temperature must be converted to the Baume degree of 20°C. Therefore, what we call honey Baume degree in daily life refers to the honey Baume degree measured at 20℃. Most beekeepers have Baume meters (commonly known as "honey meters"), which are sold in glassware stores and are not expensive, costing only a few yuan each. However, due to the influence of the temperature of the honey, the foam in the honey, the surface tension of the honey, the buoyancy of the air, the reading of values, etc., the values ??measured by beekeepers using Baume meters in wild apiaries are very inaccurate. For reference only. What is commonly used now is a handheld refractometer, also called a handheld sugar meter, which can measure three commonly used indicators of honey: baume, water content and sugar content. The handheld sugar meter is a precision optical instrument. It is more expensive, costing several hundred yuan per unit, but the measured results are relatively accurate. It is a must-have for large bee farms and honey processing companies. If there is a dispute over the inconsistent measurement results of the Baume degree of honey, the value measured by the Abbe refractometer in the laboratory shall prevail. This is the national standard for honey.
