What is the nutritional value of rayeb?
Rayeb (laban rayeb) is a traditional Egyptian and Middle Eastern fermented milk, not a fermented barley and rice drink. In one laboratory study, cow-milk rayeb had about 14.6% total solids, 4.5% fat and 4.9% protein. Values differ by milk type and recipe, so there is no single official nutrition profile.

What is the nutritional value of rayeb?
We found no official nutrition database entry for rayeb, and values depend on the milk and recipe. The one source we could open is a 2023 laboratory study of rayeb made from cow’s milk. Its control sample, plain cow-milk rayeb, measured:
| Measure | Study value (cow-milk rayeb) |
|---|---|
| Total solids | about 14.6% |
| Fat | about 4.5% |
| Protein | about 4.9% at the start |
| pH | about 4.5, falling to about 4.25 after 14 days |
These are one study’s results for a product made in a lab, not label values. Commercial rayeb, and the traditional version, can differ. The study did not report buffalo-milk rayeb. For your own tub, read the Nutrition Facts on the pack.
What is rayeb?
Rayeb (laban rayeb) is a fermented dairy product common in Egypt and the Middle East. Traditionally it was a by-product of buffalo-milk butter making: raw milk stood at room temperature for about two days, the cream was skimmed for butter, and the acidic remaining milk coagulated when heated. Today dairies make it with a defined starter culture. The study used ABT-5, which contains Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium bifidum.
Is rayeb made from barley and rice?
No. It is a milk product. Some web posts describe it as a fermented barley and rice drink, but no source we opened supports that.
Does rayeb have health benefits?
The study measured antioxidants, amino acids and probiotic counts in the product, not effects in people. Counts of the three starter cultures dipped slightly over 14 days in the fridge. We found no official body that makes health claims for rayeb. The NIH says probiotic research is promising for some conditions but often unclear on strains and who benefits.
Cautions
It contains milk and lactose, so it is not suitable for milk allergy. Acidity rose during storage (pH fell from about 4.5 to 4.25 in 14 days), so eat it fresh. Pregnant people and people with weakened immune systems should ask a doctor about live-culture foods. This is general information.
