LITERATURE REVIEW
Noble laurel from Latin -Laurus nobilis is a subtropical
tree or shrub, a species of the genus Laurel -Laurus of
the Laurel family -Lauraceae.
Its leaves are used as a spice (bay leaf). From the name
of this plant came the names Laurel, Laurentius, Laura,
Lorenz, the word "laureate", the expressions "laurel
wreath (crown)", "rest on laurels", "reap laurels".
Laurel was considered a sacred tree, its wreaths were
decorated with the heads of winners in ancient Greece.
Transcaucasia and Asia Minor are considered to be the
birthplace of the noble laurel
The noble laurel is an evergreen tree or a tall shrub
reaching 10-15 m in height, with brown smooth bark
and bare shoots. The crown is leafy, mainly pyramidal
in shape. Its life span is from 100 to 400 years.
The leaves are alternate, short-stemmed, whole-
edged, glabrous, simple, 6-20 cm long and 2-4 cm wide,
with a peculiar spicy smell; the leaf blade is oblong,
lanceolate or elliptical, narrowed to the base, dark
green above, lighter on the underside. The
inflorescences are umbellate, numerous, collected
mainly at the ends of branches 1-3 in the leaf axils.
RESEARCH METHODOLOGY
The bay leaf of which we use as a spice is obtained not
from one but from several plants, such as: Bay laurel-
Laurus nobilis, Lauraceae. Fresh or dried bay leaves are
used in cooking because of their distinctive taste and
aroma. The leaves should be removed from cooked
food before eating. The leaves are often used to flavor
soups, stews, stews and pates in many countries. Fresh
leaves are very soft and do not develop their full flavor
until several weeks after picking and drying; California
Bay leaf. The leaf of the California bay tree -
Umbellularia californica, Lauraceae, also known as
California laurel, Oregon myrtle and pepper tree, is
similar to the Mediterranean bay leaf, but has a
stronger taste; Indian bay leaf or malabatrum -
Cinnamomum tamala, Lauraceae differs from bay
leaves in that they are shorter and light or medium
green in color, with one large vein along the entire
length of the leaf. The Indian bay leaf is about twice as
long and wider, usually olive green in color and has
three veins along the entire length of the leaf. In
cooking, the Indian bay leaf is completely different,
having an aroma and taste similar to cinnamon bark
(cassia), but milder; Indonesian bay leaf or Indonesian
laurel -salam leaf, Syzygium polyanthum, Myrtaceae is
not usually found outside Indonesia; this herb is
applied to meat and, less often, to vegetables; West
Indian bay leaf, West Indian bay leaf bay tree -Pimenta
racemosa, Myrtaceae is used in cooking (especially in
Caribbean cuisine) and for the production of cologne
called bay rum; Mexican bay leaf (Litsea glaucescens,
Lauraceae).
ANALYSIS AND RESULTS
Bay leaf has a sharp, bitter taste. As with many spices
and flavorings, the aroma of bay leaf is more noticeable
than its taste. When the leaf is dried, the aroma is
herbal, slightly floral and somewhat similar to oregano
and thyme. Myrcene, a component of many essential
oils used in perfumery, can be extracted from bay leaf.
Laurel has a lot of advantages. It improves appetite,
normalizes digestion. Its leaves secrete phytoncides, it
is believed that these substances are harmful to
tuberculosis bacillus. With the help of leaves, you can
treat severe inflammation of the oral cavity, cure colds,
sore throats. The unique essential oil, which is easily
obtained from laurel, has many useful properties. It is
an effective antiviral, antibacterial and anti-
inflammatory agent. This makes the oil a universal
preparation used for medical purposes. The laurel also
