Can butter go bad in the fridge and freezer

Butter is a tasty, high-calorie and in moderation extremely useful product. It is prepared from heavily whipped cream. Does this mean that the oil can no longer deteriorate? No - the product must be kept in the refrigerator. How much butter is stored? Depending on the composition and temperature in the chamber, from 5 to 120 days.

Standard Dates

If you look at GOSTs, there are average shelf life of butter. They depend on the following factors:

  • product composition
  • its fat content
  • air temperature
  • packing material.

So, simple parchment protects the product worse than in foil - the bar loses moisture more, picks up odors more actively, it processes oxidation and polymerization faster, and when stored in the cold, and not in the freezer, the development of bacteria accelerates. As a result, the staff appears - a dark and tasteless coating on the bracket.

The figures given in the table are for packaging in foil on a paper substrate. In parchment oil in the refrigerator can be kept no longer than 20 days, in the freezer - up to 25-30 days.

Tip
In plastic airtight containers, artificial paper and other packages that do not allow air to pass through, mold is threatened with oil (unless it lies in the freezer). Pry the edge so that the oil is not clogged tightly, but also does not ventilate.

The smaller the piece of oil, the faster it will deteriorate. Therefore, having opened the pack, it is better to eat it quickly and spend on cooking.

Butter

Why is there an overestimated figure on the pack?

Today, shelf life on packs often exceeds standard. This is due either to the dishonesty of the manufacturer (the expiration date is indicated for oil packaged in barrels or boxes, for example), or the specifics of production.

What extends the shelf life:

  1. Pasteurization. Raw cream will easily bring bacteria into the oil, so the home product is worse. After pasteurization, the oil can lie for 45 days in the refrigerator (unopened).
  2. Leaven. In addition to the traditional, sour cream butter is also produced - sour cream. It is stored longer than traditional, but its taste is somewhat different.
  3. Vacuum. The oil is fed into the dispensing tap by a screw, like meat in a meat grinder. Because of this, moisture is squeezed out of the product, the finished bracket is overdried inside and moist outside - this reduces the shelf life. But if the oil is packaged in a vacuum, moisture remains in the product.
  4. Homogenization - if the equipment does not allow creating a vacuum, the oil is finely chopped before being sent to the filling machine. So moisture is squeezed out noticeably less, the product is more uniform and lasts longer.
  5. Preservation. Various special additives can extend the shelf life, but the final product is not the most useful and safe.

Food fridge

On the contrary, sweeteners, salt, and other flavoring agents shorten the shelf life of the oil.

Tip
When buying a pack, evaluate the composition. Restored or normalized cream is a sign of poor quality. But pasteurized speak in favor of the product. There should be no additional inclusions (except salt, sugar, cocoa, etc. - for taste).

How to store

Best of all, the oil is stored in a lined (paper-based) foil, tightly packed. But for sandwiches it’s inconvenient to keep the oil like that - purityis.decorexpro.com/en/ magazine recommends buying a glass, earthenware or food plastic oiler with a lid.

The cutlery will protect the product from excess air, but it will not let it shut up. However, as soon as the oil is over, the oiler must be thoroughly washed and dried in order to get rid of the products of oxidation and reproduction of bacteria. Otherwise, the new bracket will begin to deteriorate faster.

If you plan to use oil rarely, it is best to load it in the freezer. From the fact that the oil freezes, the taste is not deteriorated. The main thing is to defrost it gradually, in the refrigerator (if you plan to make sandwiches or pastries), but you can throw it immediately into porridge - it will disperse a little slower than soft.

The oil is rich in fats, which provide energy for the whole day, vitamins A, B and other valuable elements. Store it correctly, and the product will not go rancid for a long time and will delight households with taste and good.
