Understanding Cream Cheese: A Brief Introduction

The History of Cream Cheese

The genesis of cream cheese can be traced back to the 18th century in Europe, most specifically in England and France. Cream cheese, as we know it today, was, however, invented in the United States in 1872. A New York dairyman, William Lawrence, accidentally developed cream cheese while trying to replicate Neufchâtel, a French cheese type. Whether spread on a bagel or used as a baking ingredient, cream cheese has won over palates across the globe.

What Makes Up Cream Cheese?

Cream cheese is a fresh cheese made from milk and cream. In production, stabilizers, like guar gum, carob bean gum, and xanthan gum, are included for longer shelf life and a steadier consistency, especially under varying temperatures. Understanding cream cheese composition helps infer and appreciate the need for ideal storage and highlights the potential risks associated with improper handling.

Cream Cheese Variations

Over the years, cream cheese has evolved into several types each possessing unique taste, texture, and creaminess. The most common variations are whipped cream cheese, low-fat cream cheese, flavored cream cheese, and Neufchâtel – the French counterpart which is slightly lower in fat. This rich variety not only intensifies the culinary experience but also expands the discussion on storage and handling requirements for each.

Cream Cheese Safety Guidelines: How Long Can It Stay Out?

The Two-Hour Rule

Per the US Food and Drug Administration (FDA), perishable foods that have been left out of the fridge for more than two hours should be discarded. Cream cheese falls under this category due to its dairy-based nature. This guideline is based on the understanding that within the period of 40°F and 140°F (called the 'danger zone'), bacteria can double in number every 20 minutes, thereby increasing the risk of foodborne illnesses.

Factors Influencing Cream Cheese Shelf Life Out of Refrigeration

The duration that cream cheese can stay out largely depends on some factors including the room's temperature, cream cheese type, and original storage. For instance, whipped cream cheese may spoil faster due to increased surface area exposed to the environment. On the other hand, a block of cream cheese in a colder room might extend past the two-hour mark, but it's not encouraged to take the risk.

Cream Cheese Storage Traditions: The Bagel Shops' Perspective

Many bagel shops keep tubs of cream cheese at room temperature throughout the day for easier spreadability. While it's generally safe for some hours giving its thick composition that prevents rapid bacterial growth, consuming such cream cheese later in the day might be pushing the limits of the FDA’s two-hour rule.

Preserving Cream Cheese: Best Practices

Proper Refrigeration Vs Extended Shelf Life

Refrigerating cream cheese at 40°F or below can significantly extend its quality and safety. Properly stored, an opened package of cream cheese can last up to two weeks in the refrigerator. Unopened cream cheese can last up to a month. Freezing is a possible but not recommended storage method given the potential texture changes.

Tip: Key Signs to Detect Spoiled Cream Cheese

It's essential to know when your cream cheese has turned bad. Telltale signs of spoiled cream cheese include a sour smell, moldy spots, and a change in color or texture. For safety purposes, any cream cheese showing these negative indicators should be discarded immediately.

Decoding Expiry Dates: Can You Eat Cream Cheese After The Expiry Date?

Expiry dates on cream cheese, as on many food products, can sometimes create confusion. An unopened cream cheese can usually be consumed up to about one month after the expiration date printed on the package. However, once opened, it should be used within 10 days. It's essential to rely on both the expiry date and the aforementioned spoilage signs to make an informed decision.
