How Long Does Shortening Last?
Shelf Life and Storage Tips
Understanding the shelf life of shortening is essential for both food safety and culinary quality. Shortening, a solid fat often used for baking and frying, is prized for its ability to create tender pastries and its high smoke point when used in cooking. To maintain its optimal performance, knowing how long shortening lasts before it begins to deteriorate is crucial.
Unopened shortening can be stored at room temperature and tends to have a significant shelf life, lasting up to eight months according to the Food Marketing Institute's FoodKeeper. Once opened, shortening is best used within three months to ensure quality. Although shortening can last beyond these recommended periods, careful attention to storage conditions—keeping it away from heat and light—will help preserve its freshness.
Determining the longevity of shortening also hinges on the type of shortening and its exposure to environmental factors. Manufacturers often provide a "best by" date as a guideline for optimal use rather than a hard expiration date. As with many non-perishable goods, if stored correctly, shortening can remain useful for baking and cooking needs well beyond the printed dates, occasionally extending up to two years past the labeled expiration.
Understanding Shortening
Shortening is a staple in baking and cooking, known for its ability to create tender pastries and its shelf stability. This section will provide insights into what shortening is, how it compares to other fats, and its health implications.
Definition and Types of Shortening
Shortening typically refers to a fat that remains solid at room temperature. The most common type is vegetable shortening, which is made from hydrogenated vegetable oils such as soybean, cottonseed, or palm oil. Crisco, a popular brand, is a well-known example of hydrogenated shortening. Shortening can be hydrogenated or non-hydrogenated, with the former containing more saturated fat due to the hydrogenation process.
Hydrogenated: Adds hydrogen atoms to oil, increasing shelf-life and stability.
Non-hydrogenated: Lacks added hydrogen, often labeled as "trans fat-free."
Comparison to Other Fats
Compared to other fats like butter, margarine, and vegetable oil, shortening has a higher melting point which contributes to the texture of baked goods. For instance, cookies made with shortening are often softer and more stable. Margarine is similar but usually contains water and milk solids. In terms of liquid oils like vegetable oil or coconut oil, shortening is more solid, making it suitable for specific applications like pastry dough.
Comparison Table:
Fat Type Melting Point Usage in Baking Butter Low (32–35°C) Rich flavor Margarine Varied (30–40°C) Easily spreadable Shortening High (typically 46–48°C) Tender texture Vegetable Oil N/A (liquid at room temp.) Moist texture Coconut Oil Moderate (24–26°C) Flavorful
Health and Nutritional Aspects
Health and nutrition are important considerations when selecting a fat for cooking or baking. Shortening, particularly the hydrogenated kind, is high in saturated fat. Diets high in saturated fats can raise bad cholesterol levels, increasing the risk of heart disease. Non-hydrogenated shortenings, which contain less saturated fat, may be a healthier option for those concerned with dietary health impacts.
Nutritional comparison (per 100g):
Saturated fat content: Shortening (25-30g), Butter (51g), Margarine (approx. 18g)
Vegetable shortening is cholesterol-free, unlike butter or margarine which contain animal fats.
Nutritionists often recommend using fats in moderation, paying attention to types of fats consumed, and considering overall dietary balance.
Determining Shelf Life
The shelf life of shortening is influenced by various factors and can range significantly. It is paramount for consumers to differentiate between the expiration date and actual freshness and recognize the signs of spoilage.
Expiration Date Versus Freshness
Shortening comes with an expiration date which serves as a guideline for maximum freshness. An unopened container of shortening can remain fresh for up to two years past this date if stored in a cool, dark place. Once opened, it's typically best used within three to eight months for optimal quality. Freshness, on the other hand, pertains to the product's peak quality in terms of taste, texture, and performance in recipes.
Factors Affecting Shelf Life
Several elements contribute to the duration of shortening's freshness:
Storage conditions: Ideally, shortening should be kept at room temperature, away from any heat sources and sunlight.
Packaging: Properly sealed containers can extend shelf life by minimizing exposure to air and moisture.
Type of shortening: Different shortenings may have varying shelf lives; for instance, certain vegetable shortenings might last longer than others.
Signs of Spoilage
Shortening typically does not harbor mold or bacteria due to its fat content, but it can still go bad. Indicators include:
Color: Any discoloration might suggest spoilage.
Smell: A rancid odor is a clear sign that shortening should not be used.
Taste and texture: If the texture has changed or there is an off-flavor, the shortening is no longer fresh.
Consumers should trust these sensory cues above the printed expiration date to determine whether the shortening is still of good quality or if it has gone bad.
Proper Storage Techniques
Effective storage of shortening maximizes its shelf life and maintains its quality. Proper sealing, temperature control, and location are fundamental to prolonging the usability of both unopened and opened shortening.
Unopened Shortening
Unopened shortening should be kept in a cool and dry place, such as a pantry. Ideal storage ensures the shortening is away from any sources of heat and light, particularly direct sunlight which can accelerate spoilage. The original packaging, often designed to protect from air and moisture, typically suffices until the seal is broken.
Opened Shortening
Once opened, shortening's exposure to air and moisture can shorten its useful life. Transferring it to an airtight container with a secure lid is recommended. This prevents the introduction of contaminants and further protects the shortening from adverse storage conditions.
Storage Conditions and Locations
The optimal storage temperature for shortening is at room temperature or slightly cooler, but it should not be subjected to extreme temperature fluctuations. For longer-term storage, placing shortening in the refrigerator or freezer can extend its life; however, it must be sealed properly to prevent the absorption of odors and flavors. When storing in a refrigerator, ensuring that shortening is tightly wrapped or in a container is crucial to maintain its quality and consistency.

Crisco Shortening is a commonly used product, and it's crucial to remember that once opened, it has a reduced shelf life. Sealing the can tightly after each use is essential to minimize exposure to air and moisture.
Handling Post-Use:
If the shortening has been used for frying, one can reuse it several times as long as it is properly filtered and has no noticeable changes in taste or smell.
By meticulously adhering to these practices, consumers can maximize the usability of shortening, maintaining its quality for a period that can last up to a year after opening.
Health and Safety Considerations
When it comes to shortening, understanding the signs of spoilage and implementing safe handling and disposal methods are key to minimizing health risks.
Identifying Rancid Shortening
Shortening can become rancid due to oxidation over time. Indicators of rancidity include a distinct and unpleasant odor, changes in texture, and an altered appearance. If the shortening has a strong, off smell or if the color seems unusually dark, it should be considered spoiled and not fit for consumption.
Potential Health Risks
Consuming rancid shortening can pose health risks such as food poisoning. Oxidized fats may contain harmful compounds that can lead to illness. Additionally, cross-contamination can occur if the same utensils or containers are used for fresh and expired shortening, further elevating the risk of foodborne illness.
Safe Disposal Methods
To dispose of expired or rancid shortening, one should avoid pouring it down the drain as it can solidify and cause plumbing issues. Instead, it is best to place it in a sealed container and discard it with the regular trash. If there is a large amount, check with local waste management services for guidelines on proper disposal to prevent environmental harm.
