Study of the effect of extracts and oils of the local medicinal plant (thyme) in preserving some fish

Abstract

There is a growing interest in natural ingredients that can be used as preservatives in the food
industry and preservation. Among the natural materials that can be used for preservation are plant
extracts that are extracted from some natural plants, such as thyme (Thymus vulgaris ), The current
work aimed to study the efficiency of extracts and oils of local medicinal plant (thyme) in preserving
fish. Two species of fresh, economical fish writhe(sparus aurata) sardines,( sardine pilchardus )
that are widely consumed were collected during May, 2023, each species divided into two group
type, one of the two were treated with the extracts of these plants and the other group were treated
with the oils of studied plants demonstrated the effectiveness of these herbs in preserving these
fish. A comparison was made between the effectiveness of extracts and oils from these plants in
preserving the fish studied. The results showed that there were differences between the samples
before and after treatment. The results showed that there were differences between the types of
solutions, indicating that the alcoholic extract is better than the aqueous and oil extracts in the
process of preserving genetic fish and sardines. There are no differences between the types of plant
used in the experiment, which are (thyme,) Whereas a concentration of 20% is better in the
preservation process than a concentration of 10%.
