Perogie Mixture Filling Consistency

Application

One sample of perogie (or pierogi) filling was sent for preliminary evaluation. This sample is representative of the whole line of products; therefore these methods can be applied to the full range of products produced.

 

 

 

 

 

Problem

The final texture of this product is basically controlled by adding water to the product. Due to changes in the incoming product and different workers subjectively controlling the amount of water, the final product is not as consistent as the processor would like.

A product with too much water, or “wet,” would not hold its shape through the remainder of the process. On the other end,product without enough water, or “dry,” crumbles and does not hold a consistent shape. A way to objectively measure the water content and therefore control the overall texture of the product is needed.

 

 

Solution

Before testing, sample was allowed to thaw and equilibrate to room temperature (about 72 F°). A given amount (100 grams) of product was weighed and placed in a sample cup for each test replication. Because only one sample was sent, the product was manipulated to produce 3 different sample sets. It was strained in a colander to produce a “dry” product and water was added to make a “wet” product. The samples were then back extruded using a piston / plunger smaller than the container holding the sample.

All testing was done using the TMS-Pro at a speed of 100 mm/min. As the plunger moved down, the filling flowed up and around the compression piston. The samples were compressed to a distance 10 mm from the bottom of the container. The force required to deform the product gives a good indication of the way a semi-solid food will move and behave under process conditions.

 

Benefit

  • By measuring and therefore controlling texture, a processor can produce a more consistent “on target” product.
  • Allows users to objectively “see” the difference between butter and margarine products and various formulations.
  • Test suitable for all filling mixtures - mushrooms, potato, cheese or meat.

I have been working with FTC for the past 3 years, we bought in that lapse of time 2 texture analyzers with different probes fixtures for all kind of applications at our Monterrey Plant. We have always been able to count on the technical support of FTC who kindly answers our requests in a prompt manner and with the best disposition.

As we continue developing our process to achieve better results at our company, we will for sure rely on FTC for technical support and equipment upgrades that will deliver us the best possible results.

Nestle purchased a texture system from Food Technology Corporation in 2006. Since then I have recommended the texture system to several vendors in North and Central America. Staff at FTC was able to develop a simple training manual and procedure for the texture system allowing easy training in short period of time.

From purchasing of equipment through to installation and start-up, the level of personal care and service was remarkable. Shirl Lakeway and his staff at Food Technology Corporation are patient and understanding, and are always at our disposal for any assistance. Since we bought the equipment we have had no problems and feel very secure knowing that we can count on FTC for their support and service.

My first contact with FTC was through buying texture analyzer equipment as my area of interest is Rheology. We faced a problem operating the appliance. The company tried hard to help us through the internet, but the University thought it was better to send me to the company branch located in England. I received a highly advanced training course for 10 days free of charge. They provided me with programs that operate the equipment along with the information needed.

It was a great effort and outstanding support. I would like to thank Shirl Lakeway and FTC for providing me with this opportunity and for his continuous help. Finally, I encourage researchers who are interested in the physical properties of foods and dairy to choose FTC as it is a respectable and dependable company and offers the best deals concerning prices and training with different languages, such as Arabic for the Middle East.
