- Sherbet can last 3-4 months in the freezer when unopened.
- Opened sherbet lasts 2-3 months in the freezer before expiring.
- Proper storage is key to maximizing sherbet’s shelf life.
- Sherbet should be consumed before its expiration date once opened.
- Sherbet and sorbet differ in ingredients and longevity when frozen.
What is Sherbet and How Does it Differ from Sorbet?
Sherbet is a frozen dessert made with milk or cream, sugar, fruit juice or fruit puree, and sometimes egg whites. It has a creamy, smooth texture from the dairy ingredients. Sherbet contains 1-2% milkfat and 2-5% milk solids.
Sorbet is different in that it does not contain dairy ingredients. Sorbet is fruit based, containing fruit juice, puree or pulp, water, sugar, and sometimes alcohol. It has a lighter, icier texture compared to sherbet.
This difference in ingredients impacts the shelf life of opened sherbet versus sorbet. Opened sorbet can last indefinitely in the freezer if stored constantly at 0°F. Sherbet has a shorter shelf life after opening due to the dairy content.
What Ingredients Cause Sherbet to Expire?
The main ingredients that lead to sherbet expiration are the dairy components – milk, cream, milk solids, and egg whites.
Dairy products contain proteins and natural sugars like lactose that can degrade over time. Bacteria growth is also a concern in dairy-based frozen desserts. Freezer burn can also cause sherbet to dry out and develop an unappealing texture.
Fruit ingredients in sherbet generally do not cause spoilage. Fruits naturally contain acids that inhibit bacterial growth even when frozen. The sugar content also helps prevent spoilage.
How Long Does Unopened Sherbet Last When Stored Properly?
When stored continuously at 0°F or below, unopened sherbet can last 3-4 months past the “best by” date printed on the package.
Keeping sherbet frozen is critical. The University of California San Diego Food and Nutrition Department found commercially packaged ice cream and sherbet lasted over 4 months when stored at -10°F. Thawing and refreezing should be avoided as this causes ice crystals and texture degradation.
Proper storage helps maximize shelf life. The freezer should maintain a constant temperature below 0°F. The sherbet container should be kept away from the refrigerator door to avoid temperature fluctuations.
What Is the Shelf Life of Opened Sherbet?
Once opened, sherbet will last 2-3 months in the freezer if stored properly. Always check for signs of spoilage before eating, as shelf life depends on storage conditions.
A study by the US Department of Agriculture found ice cream stored continuously at 0°F remained safe for up to 2 months after opening. The study also found egg-containing ice cream lasted about 1 month before quality degradation. Since sherbet contains egg whites, consume within 1-2 months for best quality.
Keeping sherbet cold, tightly covered, and away from freezer odors helps prolong freshness after opening. Don’t store it in the refrigerator freezer, which isn’t cold enough. Consume sherbet within 3 months and before the printed expiration date on the container.
How Can You Tell if Opened Sherbet Has Expired?
Watch for these signs that opened sherbet has gone bad:
- Change in texture – Sherbet develops a grainy or icy texture when ice crystals form. Freezer burn causes dry, spongy patches.
- Dull or faded color – Loss of vibrant color can indicate oxidization and separation of ingredients.
- Off odors – Rancid, sour or bitter odors signify spoilage bacteria growth.
- Mold growth – Check for fuzzy mold on the sherbet’s surface, which signals spoilage.
- Weeping liquid – Separation of water content creates a thin liquid layer.
- Expired date – The date printed on the container indicates when to discard.
If in doubt, apply the sniff test – rancid sherbet should be discarded. Tasting stale or bad sherbet poses a health risk.
Does Frozen Sherbet Go Bad if Kept at 0°F Continuously?
Sherbet stored constantly at 0°F or below does not technically go bad, thanks to the freezing temperatures inhibiting bacterial growth.
However, frozen storage for over 4 months can result in deterioration of quality and taste:
- Increased ice crystals lead to grainy texture.
- Drying causes a spongy consistency.
- Ingredient oxidation leads to off-flavors.
- Separation of components like milk and fruit puree.
While not a food safety issue if kept frozen, lower quality means the sherbet will not be palatable. For best flavor and texture, consume frozen sherbet within 4 months of manufacture.
Can You Refreeze Thawed Sherbet?
Once thawed, sherbet generally should not be refrozen. The USDA warns against refreezing thawed ice cream or sherbet. Thawing allows bacteria and mold to grow. Refreezing stops this growth but does not eliminate pathogens that have already multiplied.
Refreezing also degrades texture. Ice crystals enlarge, creating a gritty, coarse consistency. Ingredient separation can worsen too.
However, if thawed sherbet remains refrigerated (below 40°F) and has not been left at room temperature over 2 hours, it may be safely refrozen. Inspect carefully before re-freezing – discard at any signs of spoilage like off-smells, liquid, or mold. Eat refrozen sherbet soon for best quality.
How Should You Store Sherbet for Maximum Freshness?
Follow these tips to extend the shelf life of sherbet:
- Store at 0°F or colder – This inhibits bacterial growth and slows ingredient breakdown. Set the freezer as cold as possible.
- Avoid thawing – Fluctuating temperatures cause iciness and damage texture over time.
- Seal container tightly – Prevents freezer burn, dryness, and absorption of odors.
- Limit temperature fluctuations – Open the freezer door only when needed. Don’t leave sherbet on the counter to soften.
- Clean freezer regularly – Avoid transfer of odors to sherbet from other foods.
- Keep away from walls and coils – Colder spots exist away from heat sources.
- Do not stack – Stacking can crush containers and damage lids.
- Use oldest first – Rotate inventory and eat opened containers soonest.
Can You Freeze Homemade Sherbet? How Long Does it Last?
Yes, homemade sherbet keeps well in the freezer but lasts shorter than commercial versions. Home freezing methods and ingredients result in a shorter shelf life.
According to North Carolina State University guidelines, homemade sherbet will last 1-2 months in the freezer. Properly freeze in covered airtight containers, leaving headspace to allow expansion.
For best quality, consume homemade sherbet within 1 month. Discard if any mold develops or you notice separation, iciness, or off-odors. Label containers with the date prepared.
Does Sherbet Ever Need to be Refrigerated?
Sherbet is formulated to be stored frozen, not refrigerated. The dairy components mean it requires freezing temperatures to prevent bacterial growth. Refrigerating sherbet for thawing or storage can allow spoilage.
Only when eating should you transfer sherbet from the freezer to the refrigerator to thaw for the shortest time possible. Keep refrigerated sherbet covered and consume within 1-2 days. Do not return partially-eaten sherbet to the freezer – discard any leftovers.
Refrigeration can cause condensation leading to a wet, sticky texture. It also advances separation of ingredients. For food safety and quality, sherbet must remain frozen.
Is it Possible to Freeze Sherbet Too Long?
Beyond the recommended 3-4 month freezer storage timeframe, freezing sherbet too long can badly damage its taste and texture.
Research by the University of Guelph in Canada found ice cream stored at -4°F for over 4 months developed high concentrations of water molecules in larger ice crystals. This significantly degraded smoothness and creaminess.
Extremely lengthy freezing below 0°F makes sherbet rock solid and difficult to scoop. Thawing causes large ice crystals to form, creating a grainy, icy texture. Flavor dulls due to separation of ingredients.
While freezing for over 4 months won’t make sherbet unsafe if kept frozen, the quality eventually becomes unacceptable. For best flavor and texture, consume sherbet within 3-4 months of manufacture.
What are the Best Ways to Use Expired Sherbet?
If sherbet passes its prime, you don’t necessarily need to discard it. Use softened expired sherbet in these creative ways:
- Sherbet smoothie – Blend with milk and fruit for a frosty treat. The chilling masks any iciness.
- Frozen yogurt – Mix in fresh yogurt and freeze again. This incorporates new ingredients.
- Milkshake – Adding milk, ice cream, or juice masks unfavorable textures.
- Granita – Freeze sherbet with juice in an ice cube tray for a sweet frozen slush.
- Sherbet sauce – Heat expired sherbet into a sweet sauce for ice cream or fruit.
- Baking ingredient – Fold expired sherbet into cake, muffin, or cookie batter.
With some innovation, you can repurpose thawed sherbet rather than waste it. But if overly icy, grainy, or separates easily, discarded spoiled sherbet. Consuming bad sherbet risks foodborne illness.
Does Sorbet Also Expire if Frozen?
Unlike sherbet, sorbet containing no dairy has an indefinite shelf life when frozen at 0°F consistently. The high sugar content helps prevent spoilage and texture changes.
However, sorbet quality will decline if stored frozen longer than about 6 months. Separation of fruit and liquid can occur, causing icy spots and a coarser consistency. Oxidation also causes duller colors and flavors over time.
For best quality sorbet, consume within 6 months. But lasting over a year frozen is possible if stored at 0°F and the container remains well sealed. Monitor for any signs of spoilage like mold, off-odors, dryness, or separation – at that point, discard.
The Bottom Line
When stored properly frozen, sherbet lasts 3-4 months from the manufacture date before quality declines. Once opened, eat sherbet within 2-3 months and before any printed expiration date.
Check sherbet regularly for signs of thawing damage like large ice crystals, dry patches, and separation of ingredients. Discard if any mold, off-odors, weeping liquid, or dull colors develop.
Constant freezing at 0°F or below is critical to prevent bacterial growth and maintain texture. With proper freezer storage and by following expiration dates, you can maximize the shelf life of sherbet
