How long will a fruit smoothie last if made?

Smoothies made from fresh fruits and vegetables are a delicious and nutritious snack or light meal. However, the shelf life of homemade fruit and vegetable smoothies is relatively short due to potential spoilage and food safety issues.

Factors affecting smoothie shelf life

Several factors impact how long a fruit or vegetable smoothie will last:

  • Ingredients used – Fresh fruits and vegetables have higher water content and spoil more quickly than frozen ingredients.
  • Storage temperature – Smoothies stored at room temperature spoil faster than those refrigerated.
  • Acidity level – High acid ingredients like citrus fruits help prevent bacterial growth.
  • Added ingredients – Smoothies with dairy products or protein powders spoil faster.
  • Blending technique – Smoothie separation can accelerate spoilage.
  • Handling and sanitation – Contamination introduces bacteria and speeds up spoilage.

Refrigerated shelf life

For best quality and safety, fruit and vegetable smoothies should be consumed shortly after preparation. General refrigerated shelf life guidelines are:

  • 1-2 days for smoothies made with dairy products like yogurt or milk.
  • 3-5 days for dairy-free smoothies made with mostly fruits.
  • 1-3 days for dairy-free smoothies made with vegetables or leafy greens.

These timeframes assume proper refrigeration at 40°F (4°C) or below and safe handling techniques to avoid contamination.

Room temperature shelf life

Leaving smoothies at room temperature significantly reduces how long they will last before spoiling:

  • 2-4 hours for dairy-based smoothies
  • 6-8 hours for fruit-based smoothies
  • 2-4 hours for vegetable/green smoothies

Drink smoothies immediately after preparing for best taste and nutritional value. Discard any smoothies left at room temperature for longer than recommended timeframes.

Freezer shelf life

For longer storage, prepared smoothies can be transferred to a freezer-safe container and frozen. Properly frozen smoothies can last:

  • 2-3 months for fruit and vegetable smoothies
  • 1-2 months for smoothies containing dairy, protein powder or other perishable add-ins

Frozen smoothies may be thawed in the refrigerator overnight before drinking. Give thawed smoothies a good stir or quick blend to recombine any separation.

How to maximize smoothie shelf life

Follow these tips to help homemade smoothies stay fresh and safe for consumption longer:

  • Start with quality ingredients – Use fresh, ripe fruits and vegetables. Wash produce thoroughly.
  • Refrigerate components – Keep fruits, veggies, juices, milks, yogurt, etc. chilled before blending.
  • Freeze overripe produce – Use frozen fruit instead of browning bananas or berries.
  • Blend well – Thoroughly puree chunks to prevent separation and spoilage.
  • Use acidic fruits – Citrus, pineapple, berries help control bacteria growth.
  • Limit dairy – Smaller amounts of yogurt or milk extend shelf life.
  • Sanitize equipment – Wash blender jar, utensils in hot, soapy water.
  • Transfer to clean container – Don’t store in blender jar long-term.
  • Refrigerate promptly – Chill for at least 2 hours before consuming.
  • Avoid contamination – Don’t double dip tasting spoons back into smoothie.

How to tell if a smoothie is bad

Watch for these signs that a refrigerated or thawed smoothie has spoiled and should be discarded:

  • Separation of ingredients – Layer of fruit pulp or juices at top or bottom
  • Change in texture – Becomes very thick, slimy, watery or chunky
  • Off odors – Smells sour, moldy, rotten or fermented
  • Change in color – Unnatural darkening or graying
  • Fizzing or bubbling – Due to fermentation
  • Mold – Hairy or fuzzy spots or specks

Taste testing spoiled smoothies should be avoided, as bacteria like salmonella, E. coli, and listeria can cause foodborne illness. When in doubt, throw it out.

Food safety tips

Follow proper food handling and hygiene practices when preparing, storing and drinking homemade smoothies:

  • Wash hands and produce thoroughly before blending.
  • Use clean, sanitized equipment and containers.
  • Keep ingredients chilled at safe temperatures until blending.
  • Blend and refrigerate smoothie quickly.
  • Store refrigerated at 40°F or below.
  • Only thaw frozen smoothies in the refrigerator.
  • Discard when signs of spoilage appear.
  • Do not leave smoothies at room temperature over 2 hours.

At-risk groups including very young children, elderly, pregnant women, and those with weakened immune systems should take extra care with homemade smoothie safety and storage times.

Storing smoothie ingredients

Proper storage of smoothie ingredients also helps extend the shelf life once blended:

Ingredient Refrigerator Freezer
Fresh fruits 5-7 days 6-12 months when frozen
Leafy greens 3-5 days 6-12 months when frozen
Vegetables 7-10 days 8-12 months when frozen
Berries 2-3 days 6-12 months when frozen
Yogurt 7-10 days past sell-by 1-2 months when frozen
Milk 5-7 days past sell-by 3 months when frozen
Juices 5-7 days 6-12 months when frozen

Wash, prep, cut and freeze overripe or extra fresh produce to have ingredients ready to create smoothies anytime.

Smoothie storage containers

Using the right storage containers helps maintain smoothie freshness and extend shelf life:

  • Blender jar – Only for short-term storage. Transfer smoothies to another container after blending.
  • Plastic bottles or jars – Affordable, disposable option for 1-2 day storage.
  • Glass jars or bottles – Reusable options that won’t hold stains or odors.
  • BPA-free plastic – Avoid plastic containers with BPAs that can leach into food.
  • Air-tight lids – Prevent air exposure that degrades smoothies faster.
  • Freezer-safe – For smoothies being frozen for longer shelf life.
  • Single serve size – Small portions stay fresher than batch sizes.

Always opt for clean, sealed containers kept at proper temperatures to store smoothies safely.

Preserving nutrients in stored smoothies

Over time, some vitamin and antioxidant loss will occur in stored smoothies. Follow these tips to help maximize nutrition:

  • Blend until smooth – Breaks down produce cell walls to release nutrients.
  • Refrigerate promptly – Slows vitamin degradation at cool temps.
  • Limit oxygen – Air causes nutrient oxidation, so minimize headspace.
  • Use frozen fruit – Locks in nutrients vs. fresh fruit.
  • Add lemon juice – The acidity helps stabilize vitamins.
  • Steer clear of light – UV rays speed up nutrient breakdown.
  • Drink ASAP – Freshest smoothies have the most vitamins.

While some nutritional value is lost over time, homemade smoothies stored properly still provide many healthy benefits.


Homemade fruit and vegetable smoothies have a relatively short shelf life. For best quality and safety, they should be consumed within 1-5 days when refrigerated, or within 2-3 months if frozen. Proper handling, sanitation, storage temperatures, and air-tight containers can help maximize how long a smoothie will last. Watch for signs of spoilage and discard smoothies promptly when they occur. Following food safety recommendations will allow you to enjoy fresh, nutritious smoothies without worrying about foodborne illness.
