Does Carob Contain Caffeine?
Carob is often referred to with the question "Does it contain stimulants like cocoa?" due to its cocoa-like color and aroma. Scientific reviews and laboratory analyzes show that carob fruit flesh does not contain caffeine and theobromine, or that the measurement methods of these compounds are below the detection limit.
In this article, we discuss what caffeine and theobromine are, what levels of these substances are present in cocoa and chocolate products, what the analyzes on carob say, and how carob can be evaluated for those who want to avoid caffeine, along with their sources.
Short Answer: Does Carob Have Caffeine?
The fleshy part of the carob (Ceratonia siliqua L.) fruit, that is, the part that is the raw material of carob flour, powder and molasses, is defined as a caffeine and theobromine-free food. In a comprehensive review on carob fruit meat, it is emphasized that carob does not contain the sensory and chemical properties similar to cocoa, as well as its "lack of stimulant alkaloids theobromine and caffeine", making it a healthier potential substitute for cocoa (Rodríguez-Solana et al., 2021).
A more recent review examining carob-based beverages underscores the same point: the absence of caffeine and theobromine makes carob a viable alternative to cocoa for those looking to avoid alkaloid stimulants (Buzzanca et al., 2025). This information is based on a detailed review that addresses carob as a cocoa substitute (Loullis & Pinakoulaki, 2018).
There is a small but important detail here: In scientific language, the expression "does not contain" often means "not found to be measurable by the analysis method used". The review by Rodríguez-Solana et al. also states that carob "does not contain or contains trace amounts" of these substances. In practical terms, this means that carob is not a food known for its stimulating effect like cocoa or coffee.
What Are Caffeine and Theobromine?
Caffeine and theobromine are purine alkaloids found in some plants in nature and fall into the methylxanthine group. The two compounds are chemically very close to each other; the difference between theobromine (3,7-dimethylxanthine) and caffeine (1,3,7-trimethylxanthine) is only one methyl group. Caffeine; It is the main alkaloid of coffee beans, tea and mate leaves. Theobromine is known as the basic alkaloid of the cocoa bean (Rodríguez-Solana et al., 2021).
Both compounds may have a stimulating effect on the central nervous system. In the same review, it is stated that various negative effects such as behavioral changes and increased blood pressure are associated with the consumption of these substances, but the findings are not consistent. The review also points out that children may be more sensitive to caffeine and theobromine because the detoxification mechanisms in the body are not fully developed.
In a cocoa-specific evaluation, it is argued that theobromine is found in much higher amounts than caffeine in cocoa and that theobromine may play a role in some of the known effects of cocoa (Martínez-Pinilla et al., 2015). In short, when talking about cocoa, it is necessary to look not only at caffeine, but also at theobromine, which is much more abundant than it.
How Much Caffeine and Theobromine Are in Cocoa and Chocolate?
To understand what it means for carob to be "caffeine-free", it is useful to first look at the levels in cocoa. The US Department of Agriculture's (USDA) FoodData Central database reports approximately 2,057 mg of theobromine and 230 mg of caffeine per 100 grams for unsweetened cocoa powder. The carob flour record in the same database does not include caffeine and theobromine values (USDA FoodData Central, FDC 169593 and FDC 173755).
In a classic analysis of chocolate products, the average theobromine rate in commercial cocoa was found to be 1.89% and the caffeine rate was 0.21%. In the same study, the average theobromine in milk chocolates was 0.15% and caffeine was 0.02%; in a 5-ounce serving of hot cocoa of approximately 150 ml (5 ounces), an average of 65 mg of theobromine and 4 mg of caffeine were measured. The authors also noted that methylxanthine content varied widely in each product group (Zoumas et al., 1980).
| Product | Theobromine | Caffeine | Source |
|---|---|---|---|
| Unsweetened cocoa powder (100 g) | ~2,057 mg | ~230 mg | USDA FDC 169593 |
| Commercial cocoas (average) | %1,89 | %0,21 | Zoumas et al., 1980 |
| Milk chocolate (average) | %0,15 | %0,02 | Zoumas et al., 1980 |
| 50 g dark chocolate | ~250 mg | ~19 mg | Martínez-Pinilla et al., 2015 |
| Carob flour / powder | Not detected | Not detected | Papaefstathiou et al., 2018 |
The figures in the table should not be used interchangeably as they were obtained in different years, by different methods and on different products. Nevertheless, the general picture is clear: Cocoa and products with a high cocoa content contain a significant amount of theobromine and a smaller amount of caffeine, while carob does not contain these substances at a measurable level.
What Do the Analyzes Made on Carob Show?
The knowledge that carob is caffeine-free is not only based on a traditional assumption. In a nutritional characterization study of carob and traditional carob products in Cyprus, caffeine and theobromine were analyzed by high-performance liquid chromatography (HPLC) and both compounds were found to be below the detection limit of the method (Papaefstathiou et al., 2018; cited in Rodríguez-Solana et al., 2021).
Reviews evaluating carob as a cocoa substitute point to the same conclusion. Loullis and Pinakoulaki's (2018) review, which delves into composition, health effects, and food applications, explains one of the reasons why carob stands out as an alternative to cocoa is the absence of stimulant alkaloids. Buzzanca et al. (2025), on the other hand, state that carob drinks are free from caffeine and theobromine, making them interesting for different consumer groups, such as the elderly, children, and people with food intolerances.
Since carob flour, powder and crumb are obtained from the fleshy part of the fruit, this information also applies to the products in question. Carob molasses is also not a source of caffeine because it is produced from the water-soluble part of the same raw material. However, it should be noted that other ingredients may be present in ready-made products; we will talk about this separately below.
Other Differences Between Carob and Cocoa
Caffeine and theobromine are not the only properties that distinguish carob from cocoa. Although comparing cocoa and carob in detail is the subject of a separate article, it is useful to know a few key differences associated with the caffeine question.
| Oil | According to USDA data, 100 grams of unsweetened cocoa powder contains about 13.7 g of fat, while carob flour has about 0.65 g. |
| Sugar | Carob is naturally sweet; About 49 g of sugar is reported per 100 grams of carob flour. In unsweetened cocoa powder, this value is below 2 g. |
| Fiber | Both products are rich in fiber; USDA records include about 39.8 g of dietary fiber for carob flour and about 37 g for cocoa powder. |
| Taste | When roasted, carob acquires an aroma reminiscent of cocoa; this increases consumer acceptance (Buzzanca et al., 2025). |
These differences mean that when carob is used as a substitute for cocoa in a recipe, the balance of sweetness and fat needs to be readjusted. For example, it has been reported that muffins made with carob powder instead of cocoa produce a sweeter result than cocoa samples, which may offer the opportunity to reduce added sugar (Pawłowska et al., 2018; cited in Buzzanca et al., 2025).
Carob for Those Who Avoid Caffeine
Carob can be an alternative to cocoa products for people who know that they are sensitive to caffeine, do not want to consume stimulant drinks in the evening, or need to limit caffeine with the recommendation of their physician. Although it does not give the unique taste of cocoa in exactly the same way, it provides a similar color and pleasant aroma in recipes such as hot milk, herbal drinks, smoothies, puddings or homemade cakes.
This feature is also important for children. There are evaluations that caffeine and theobromine should be handled more carefully in children (Rodríguez-Solana et al., 2021). A study conducted in Turkey on the development of a nutritious spreadable cream for children based on carob flour also shows that carob is considered as an alternative to cocoa in children's snacks (Aydın & Özdemir, 2017). Similarly, carob powder is also being investigated in milk-based dessert formulations (Şanlı, 2023).
However, being "caffeine-free" does not mean "unlimited consumption". Carob is a food rich in natural sugar, and condensed products such as carob molasses are even higher in sugar. Therefore, while avoiding caffeine, it is necessary not to overlook sugar intake and keep portions balanced.
Reading the Label on Carob Products
Pure carob flour, powder, cracks, or molasses do not contain caffeine. However, some mixed products on the market may use caffeine sources such as cocoa, coffee, tea extract, or guarana along with carob. The phrase "carob" does not indicate that the product consists entirely of carob.
- Look for cocoa, cocoa butter, cocoa mass, or chocolate in the ingredient list.
- Pay attention to ingredients such as coffee, tea, green tea extract, guarana.
- In products such as "carob chocolate", check if carob is the only source of flavor.
- If you are buying as raw material, make sure that the product is one-component, pure carob.
This control is especially important for people who need to avoid caffeine altogether and for manufacturers who prepare products for children.
Frequently Asked Questions
Does carob powder make you sleepy like cocoa?
Since caffeine and theobromine are not measurable in carob powder, the stimulating effect of cocoa due to these substances is not expected. However, sleep quality depends on many factors.
Does carob molasses have caffeine?
Pure carob molasses is not a source of caffeine as it is produced from carob fruit, which does not contain caffeine. It is necessary to check the label for mixed products.
Does roasted carob gain caffeine?
The roasting process has an effect on aroma and color; however, it does not create caffeine, which is not found in the fruit. The similarity due to the aroma of roasted carob, reminiscent of cocoa, is only sensory.
Is carob an exact substitute for cocoa?
It is a good alternative in terms of color and aroma, but the sweetness, fat and flavor profile are different. Sugar and fat ratios may need to be readjusted in recipes.
