This article delves into the most asked question: How long does tahini last in the fridge after opening?

Exploring its shelf life in the fridge and offering practical insights, this guide aims to assist tahini enthusiasts in maximizing its longevity while ensuring a delightful culinary experience.

What is tahini?

Tahini is a lusciously smooth paste crafted from toasted, ground sesame seeds. This versatile ingredient boasts a creamy texture and a rich, nutty flavor profile, making it a staple in various cuisines particularly Middle Eastern and Mediterranean. 

Its preparation involves meticulously grinding sesame seeds to create a thick, spreadable consistency that can range from light beige to a deep, dark hue depending on the sesame seeds’ roasting intensity. 

Tahini serves as a foundation for many dishes. It adds depth and complexity to recipes, whether it is used as a standalone condiment, a key component in dressings, or as an essential element in dishes like hummus or halwa. 

Beyond its culinary allure, tahini also presents a nutritional treasure trove. It is packed with essential vitamins, minerals, and healthy fats that make it a sought-after ingredient for both its taste and its numerous health benefits.

Do tahini need to be refrigerated? 

Tahini can generally be stored at room temperature before opening but refrigeration is recommended after the jar or container has been opened. 

The primary reason to refrigerate tahini after opening is to preserve its freshness and prevent it from going rancid. 

Sesame seeds contain natural oils that can turn quickly when exposed to air and light, leading to a decline in quality and taste. Refrigeration also helps slow down the oxidation process, ultimately extending the shelf life of tahini significantly. 

Moreover, cooler temperatures maintain the consistency of tahini, prevent the separation of ingredients and ensure a creamy texture, making it more enjoyable to use in various culinary creations. 

Additionally, refrigerating opened tahini also reduces the risk of bacterial growth, enhancing its safety for consumption over an extended period.

How long does tahini last in the fridge after opening?

Unlike other packaged goods, tahini can last longer in the fridge. It is mainly because tahini contain natural oils which act as preservative and increase the shelf life of this delicious treat. 

Once opened and properly refrigerated, tahini can typically last for around 6 to 12 months without a prominent change in its quality and flavor. However, this timeframe can vary based on several factors. 

Therefore, it is essential to tightly seal the container or transfer the tahini into an airtight container before refrigeration. It will prevent exposure to air (oxidation) and bacterial growth due to moisture content which can lead to quicker spoilage.

How long does unopened tahini last in the fridge?

Unopened tahini tends to have a longer lifespan than an opened jar of tahini in the cold temperatures. When stored properly in the refrigerator, an unopened tahini jar can maintain its quality typically from one to two years. 

The lower temperatures of the fridge help to maintain the freshness by preserving the natural oils present in sesame seeds which are the basic component of tahini, effectively extending its shelf life.

However, it is crucial to keep the jar tightly sealed and away from moisture or direct light to prevent any potential degradation in flavor or texture and bacterial proliferation. 

How long does homemade tahini last?

Homemade tahini has limited shelf life as compared to the commercially prepared tahini. It can last anywhere from 2 to 4 months without any drastic change in quality or taste. 

The reason is the absence of preservatives commonly found in commercially produced tahini which help to extend its shelf life. 

Also, the natural oils in sesame seeds used for making homemade tahini can turn rancid relatively faster without the additives or stabilizers, further limiting its shelf life. So, it is better not to keep homemade tahini beyond its recommended timeframe. 

Best way to store tahini

The best way to store tahini and preserve its quality for extended periods involves a few key practices.

Pantry 

  • Store the unopened container or jar of tahini in a cool, dry, and dark place like a pantry or cupboard away from direct sunlight and heat sources. It will last for more than a year in its best possible quality. 

In the refrigerator 

  • Once opened, transfer the remaining tahini into an airtight container to minimize its exposure to air which can lead to quicker spoilage. 
  • Ensure the lid of the container is tightly sealed after each use to prevent bacterial growth.
  • Make sure you label the jar with date to keep track of freshness.

Can you freeze tahini successfully?

Yes, of course. Tahini can be successfully frozen to extend its lifespan. Freezing tahini is a viable method to preserve it for a longer duration, especially if you’ve bought it in bulk or made a large batch at home. Frozen tahini can last for years in the freezer. 

Before freezing, make sure the tahini is stored in an airtight container or freezer-safe resealable bag, leaving some space at the top for expansion. 

However, freezing might cause some separation or changes in texture, so it is recommended to stir the tahini thoroughly before freezing and again after thawing to restore its consistency. 

When ready to use, allow the frozen tahini to thaw in the refrigerator overnight. But avoid frequent thawing and refreezing as this can impact its taste and texture.

Is tahini healthy?

Tahini offers numerous health benefits due to its nutrient-rich composition. Here are some key health benefits of tahini:

  • Nutrient Dense: Tahini is a powerhouse of essential vitamins and minerals including calcium, iron, magnesium, phosphorus, and potassium which all promote overall well-being and support various bodily functions.
  • Rich in Healthy Fats: It contains predominantly healthy fats, primarily unsaturated fats like omega-3 and omega-6 fatty acids, which are highly beneficial for heart health and reduces the risk of cardiovascular diseases.
  • Good Protein Source: Tahini provides a moderate amount of protein that makes it a great addition for individuals following vegetarian or plant-based diets, aiding in muscle repair and growth.
  • Antioxidant Properties: It contains antioxidants like sesamin and sesamol which help neutralize harmful free radicals, potentially lowering the risk of chronic diseases and supporting overall health.
  • Bone Health: Tahini is an excellent source of calcium. It is vital for maintaining strong bones and teeth, making it particularly beneficial for individuals at risk of osteoporosis or those needing to boost their calcium intake.

How to tell tahini has gone bad?

Detecting spoilage in tahini involves observing changes in its appearance, smell, and texture. Here are some common indicators that tahini might have gone bad:

  • Off Odor: Give tahini a good sniff. Fresh tahini has a nutty, slightly sweet aroma. If it emits a rancid, sour, or off-putting smell, it is a clear indication of spoilage.
  • Unusual Appearance: Inspect the tahini for any mold growth, unusual discoloration, or dark spots on the surface. Mold growth is a clear sign that the tahini has spoiled and should be discarded immediately.
  • Texture Changes: Tahini should have a smooth and creamy consistency. If you notice a grainy or gritty texture, or if it separates into layers and doesn’t blend back together after stirring, it might have deteriorated.
  • Bad taste: While visual and olfactory cues are primary indicators, if the tahini looks fine but smells slightly off, tasting a small amount can help confirm its quality. A sour or bitter taste is a strong indication of spoilage and consuming it is not advisable at all.

FAQs

Why does my tahini taste bitter?

Tahini can taste bitter due to the sesame seeds’ natural bitterness or if the seeds are over-roasted before processing, it can contribute to bitter tahini.

Do you stir tahini before using?

Yes, it is recommended to stir tahini nicely before using. Tahini tends to separate with its oil rising to the top and solids settling at the bottom. Stirring blends these components back together and ensures a consistent texture and flavor.

Does lemon thicken tahini?

Yes, adding lemon juice to tahini can potentially thicken its consistency. It is because the acidity in lemon juice can cause tahini to slightly firm up or thicken due to a reaction that occurs between the acid and the proteins in the tahini.
