Golab Raiha Laboratory
The quality control laboratory of Gulab Raiha company, with a laboratory equipped with microbiological devices, chemical methods and determining the amount of essential oil, and using expert and experienced forces in an effort to produce and supply healthy products in accordance with the national standards of Iran, in order to increase satisfaction It is customers.

Different departments of quality control laboratory of Golab Raiha company:

Public space, sample receiving and storage place, sample testing place (room for preparing and sterilizing culture media and equipment, culture room equipped with UV lamp and microbial hood and chemical hood, incubation room or greenhouse)

Microbial tests of rose water and herbal extracts:
Food microbiology is a branch of microbiology that deals with issues such as knowing the contamination and spoilage of food and the microbial agents that cause them, methods of identifying and counting microorganisms in food, and knowing diseases caused by microorganisms, etc. .. will pay.

Organisms that are studied more in microbiology mainly include bacteria, molds and yeasts, viruses and single cells and protozoa.

According to the national standards of Iran, the microbiology of rose water - features number 3270 and the microbiology of herbal extracts - features number 3545, the microbiology features of rose water are according to the following table:

 

 

And for herbal extracts, it should be according to the following table:

 

 

Chemical tests of rose water and herbal extracts:
Acid number: the amount of milligrams of neutralized acetic acid in 100 ml of sample, which is a measure to determine the freshness and age of rose water and spirits.

Oxidation number: the amount of 0.01 milliliter of potassium permanganate is normal, which is consumed by 100 milliliters of the sample in the test conditions in half an hour, the oxidation number is a measure of the quality of the essential oil.

Iodine number: the amount of 0.1 milliliter of iodine is normal, which is consumed by 100 ml of sample under test conditions. Iodine number, like the oxidation number, is a measure of the quality and quality of the essential oil of the sample.

Ester number: the amount of milliliters of sodium hydroxide solution is 0.01 normal, which is necessary to saponify the ester in 100 ml of the sample under the test conditions, the ester number is a measure of the quality of the essential oil of the sample.

The higher the number of esters, the better the quality of the sample, because it is a sign of better preservation of the essential oil in the plant after picking and its better extraction in the production process and good storage conditions, because esters are sensitive and are decomposed and destroyed in inappropriate conditions. Process.

Essential oil: is a volatile and aromatic substance of a plant that contains a complex mixture of organic chemicals such as terpenoids, aldehydes, alcohols, esters.
