Abstract:
Council Directive 2001/110 / EC (1) defines honey as the sweet natural substance produced by Apis
mellifera bees. Honey contains especially different types of sugars, especially fructose and glucose, as well as
other substances, such as organic acids, enzymes and solid particles resulting from honey collection. (1). It is
an aqueous solution rich in sugary substances up to 80% represented mainly by glucose and fructose that come
from the floral nectar, extrafloral, manna and other sources, collected by bees and stored in honeycombs. The
enzymes, which the bees introduce into the nectar, have the ability to split sucrose, maltose, melioidoses, raffinose,
melibioses', this process lasting for many years. The transformation of the nectar by the bees into honey
is then accompanied by the exchange and replacement of the content of useless acids, with the release of the
surplus water. The pH value of the matured shoulder varies from 3,5-5.5, depending on its floristic origin. The
bees depend exclusively on the plant world for their nutrition and, therefore, throughout the active season,
they make sustained efforts to provide food, both for immediate needs and for reserves (2). Typically, the bees
feed on nectar, honey, pollen, water and for the use of larvae and quail feeds, in addition, milkweed is used.
Except for the water, the honey and pollen are stored as reserves. Artificially, a wide range of food can be used
in bee feed: the sugar syrup and sherbet, the cough sugar, the powdered sugar mixed with yeast, the powdered
milk, delipidated soybean meal, corn pollen, various cereal flours, medicines as well as herbal supplements.
From nectar, manna or sweet juices, which are found in the different parts of plants and trees, in combination
with some substances that are born in the salivary glands of bees, honey is obtained, which the bees deposit in
the honeycomb cells. Subsequently, the honey is stored in the honeycomb cells and left in the air for a while,
through evaporated water. Finally, these cells are tightly sealed with some wax caps (3). In this research we
performed experiments on medium samples of acacia, linden, coriander, sage, manna, polyflower honey (average
tests of honey from Nord East Region of Romania) and we detected minor inaccuracies related to the
level of dextrin in sage honey, as well as a low level of sucrose in sage honey and acacia honey.
