Nutritional Value of Carob Molasses
Carob molasses is a traditional product obtained by condensing the water-soluble components of the carob fruit, and most of its dry matter consists of sugars. It also contains minerals such as potassium, calcium and magnesium and phenolic compounds; however, these values vary widely from product to product.
In this article, we discuss the sugar, mineral and phenolic content of carob molasses, the quality criteria in the standard and the portion approach in daily consumption based on scientific sources, especially the analyzes made on samples collected from the market in Turkey.
What Components Does Carob Molasses Consist of?
Carob molasses is obtained by extracting ripe carob fruit with water, filtering and concentrating. Production Process What is Carob Molasses and How is it Made? We explained it in detail in our article. In this article, we focus on what the resulting product contains in terms of nutrition.
To understand the composition of molasses, it is necessary to first look at the raw material. Carob pulp is a fruit rich in sugar. According to one review, the total sugar in different varieties varies between approximately 40–55 g per 100 grams of dry matter, with sucrose accounting for the largest portion of these sugars (Goulas et al., 2016). In another review, the total sugar in the pulp was given in the range of 30–60 percent; it was stated that sucrose made up 65–75 percent of the total sugar, while fructose and glucose made up the remaining part (Dahmani et al., 2023).
During extraction, some of these sugars, water-soluble minerals and phenolic compounds pass into the liquid. Insoluble fiber, which makes up most of the pulp, remains largely in the pulp. By removing water during the condensation phase, sugars and other dissolved substances become concentrated. Therefore, from a nutritional point of view, carob molasses is primarily a dense source of carbohydrates (sugars); minerals and phenolic compounds are secondary components found in this dense sugar matrix.
Dry Matter and Sugar Content
One of the most basic indicators of quality and density in molasses is the water-soluble dry matter (SCKM) value; in everyday language, this value is often expressed as "Brix". In the study in which carob molasses samples collected from the market in Turkey were analyzed, water-soluble dry matter was found to be between 69.0-79.4 percent. In the same study, the sucrose content of molasses samples was measured in a very wide range of 4.31–37.15 g per 100 g (Yavuz Küçük & Duraklı Velioğlu, 2022).
This wide variability in sucrose is remarkable. Since heat treatment and acidic environment can lead to the breakdown of sucrose into glucose and fructose (formation of invert sugar), the sugar distribution may also differ in products with different production conditions. Therefore, the "sugar content" of a molasses depends not only on the total sugar, but also on which sugars it consists of.
In the introduction of a clinical study conducted with commercial carob syrups in Spain, it is stated that carob syrup contains approximately 63.88 percent sugar, 1.4 percent protein and 3.3 percent crude fiber and does not contain fat, citing a previous study. In the same study, it was stated that 15.7 g of syrup used for glycemic testing contained 10.4 g of carbohydrates (Planes-Muñoz et al., 2025). Syrup and traditional Turkish molasses may not be the same product; nevertheless, these values are insightful as they show that more than half of the concentrated products obtained from carob consist of sugar by weight.
Does Molasses Have Added Sugar?
Traditional carob molasses gets its sweetness from the fruit's own sugars. However, it is not correct to assume that this applies to every product unless the composition of the products on the market is controlled. The list of ingredients on the label is the first place to look in this respect. We also discuss the issue of reading the label in our article Guide to Reading Labels on Carob Products.
Mineral Content: Potassium, Calcium, Magnesium and Iron
Carob is a fruit that has also been examined in terms of minerals. Referring to a study conducted on Anatolian carob pods, it is reported that there are approximately 970 mg of potassium, 300 mg of calcium and 1.88 mg of iron in 100 g (Dahmani et al., 2023). These values do not belong to molasses, but to the fruit itself.
The mineral content in molasses depends on the amount transferred to the liquid by extraction and the degree of condensation. The mineral ranges measured in the analysis of commercial molasses in Turkey are summarized below (Yavuz Küçük and Duraklı Velioğlu, 2022). To facilitate comparison, we also converted the mg/kg values to approximate values corresponding to 100 g.
| Mineral | Measured range (mg/kg) | versus 100 g (approx., mg) |
|---|---|---|
| Potassium (K) | 4600,53–12357,24 | 460–1236 |
| Calcium (Ca) | 380,55–1093,46 | 38–109 |
| Magnesium (Mg) | 205,80–582,83 | 21–58 |
| Phosphorus (P) | 297,62–780,74 | 30–78 |
| Sodium (Na) | 180,20–2121,72 | 18–212 |
| Iron (Fe) | 2,20–78,54 | 0,2–7,9 |
In the study, zinc was measured in the range of 1990.65–4879.56 μg/kg, and copper was measured in the range of 334.69–734.44 μg/kg (Yavuz Küçük and Duraklı Velioğlu, 2022).
As can be seen from the table, potassium is the mineral found in the highest amount in carob molasses. However, in some minerals, especially iron and sodium, the difference between the examples is very large. The wide range in iron may be related not only to the raw material, but also to the production equipment and process conditions; therefore, generalizations such as molasses "is a source of iron" should not be made without verification for a single product. Common beliefs about carob and iron are a topic that deserves to be evaluated under a separate heading.
What Do Minerals Mean Per Serving?
A tablespoon of molasses is about 15–20 g (varies depending on the fullness of the spoon and the density of the product). Considering the above ranges, 20 g of molasses can provide approximately 90–250 mg of potassium and 8–22 mg of calcium, depending on the product. This calculation shows that the mineral contribution of molasses remains at a "complementary" level in the daily diet and should not be considered the main source of minerals.
Phenolic Compounds and Antioxidant Capacity
Carob molasses also carries phenolic compounds that pass through the fruit. The total phenolic content in commercial molasses in Turkey was found to be in the range of 5.80–18.00 mg gallic acid equivalent/g (Yavuz Küçük & Duraklı Velioğlu, 2022). Another study examining carob syrups identified 75 phenolic compounds, with gallic acid being the most abundant compound in all samples. The same study demonstrated that after simulated digestion, gallic acid was largely degraded, retaining a significant portion of the antioxidant capacity (Zannini et al., 2024).
Phenolic content is also affected by production conditions. Heat treatments above 40 °C have been reported to reduce the amount of phenolic substances in syrups (Ioannou et al., 2023). We discussed the types of carob polyphenols and how research should be interpreted in our article Carob Polyphenols and Scientific Studies.
Quality Criteria: Dry Matter, HMF and Acidity
Correctly interpreting the nutritional value of a molasses is not independent of the quality characteristics of the product. Yavuz Küçük and Duraklı Velioğlu (2022) convey some of the criteria in the TS 13717 Carob Molasses Standard in their study as follows:
- Brix (water-soluble dry matter): at least 70%
- pH: 4.5–6
- Sucrose: 20–40 percent
- Total ash: no more than 3.5 percent
- HMF (hydroxymethylfurfural): not more than 30 mg/kg
- Titration acidity (in citric acid): 0.12–0.9%
In the same study, the pH was found in the range of 4.90–5.28, acidity 0.39–0.90 percent and HMF 0.79–50.25 mg/kg in molasses samples; it was stated that some samples did not meet the criteria for sugar, HMF and Brix. HMF is a compound that can be formed by heating and storing sugary products for a long time and is used as an indicator of heat treatment intensity. High HMF values may indicate that the product has been overly heat treated or kept in unsuitable conditions.
Portion and Balanced Consumption
There is no officially determined daily consumption amount for carob molasses. However, considering that more than half of the product by weight consists of sugar, it is a logical approach to consume molasses in moderate amounts as a sweetener or breakfast.
To give you an idea, in a 6-week study with commercial carob syrups, participants were asked to consume 10 g of syrup daily, six days a week (Planes-Muñoz et al., 2025). This amount is roughly one to two teaspoons, depending on the fullness of the spoon. In the same study, the glycemic index of the syrups was measured as approximately 56 and 60, and it was reported that the blood sugar response was lower than glucose; the authors emphasized that the findings should be considered as preliminary evidence.
In practical terms, the following points can be kept in mind:
- It creates a more balanced meal when consumed with foods containing protein, fat or fiber such as molasses, tahini, yogurt or whole grain bread.
- Added sugar can be reduced in recipes that use molasses.
- People with diabetes or monitoring blood sugar should consult their physician or dietitian before adding molasses to their nutrition plan.
- The energy and sugar values per 100 g should be checked by looking at the nutritional statement on the label of the product.
Is There a Nutritional Difference Between Carob Molasses and Carob Extract?
In recent years, there have been products on the market called "carob extract", which are stated to be produced by cold extraction and low-temperature condensation. Yavuz Küçük and Duraklı Velioğlu (2022) compared these products with carob molasses and found no statistically significant difference between the two groups in terms of the chemical properties examined. The authors also stated that there is no separate standard or communiqué in the legislation for "carob extract". Therefore, the name "extract" alone does not mean higher nutritional value; it would be more accurate to look at the label and analysis information when evaluating the product.
Frequently Asked Questions
