100% SAFER FOOD SYSTEMS WITH THE USE OF BUFFERLIQUID EXTRACT®

 

Application of Bufferliquid Extract® for safer and longer preservation of fresh vacuum-packed and treated meat products (beef, mutton, veal, chicken fillets, fresh minced meat and frying sausages).

Materials and methods
Explanation for safer and longer preservation of fresh meat products such as beef, mutton, veal, chicken fillets, fresh minced meat and frying sausages).

Application of Bufferliquid Extract® and finishing with vacuum system (tumbling)





 

A. 25 kg of each of the above meat products was completely sprayed with 250g of Bufferliquid Extract® during 2 minutes under vacuum and subsequently vacuum-packed.   B. The test meat without Bufferliquid Extract® is vacuum-packed according to the old system without adding any natural preservatives.

Discussion :
Tests A and B were stored vacuum-packed in the refrigerator at a temperature of minimum 2 degrees Celsius and maximum 5 degrees Celsius for 20 days. The following analyses were subsequently performed on all products and are summarised as follows :

Conclusion :

microbiological and technological improvement
Because of the application of adjusted buffer values and Aw value on all product preparations the following advantages are obtained:

  • a shelf life twice as long for heated and fresh products
  • improved taste and colour
  • natural colour of the cutting surface maintained for a longer period of time
  • stable pH value adapted to each individual meat preparation
  • drop of the total number of bacteria by +/- 1 logarithm
  • based on the analysed parameters the conclusion can be reached that the microbiological quality of beef, mutton, veal, chicken fillets, frying sausages and fresh minced meat is significantly better. A stable pH value was obtained as a result of the application of Bufferliquid Extract®

sensory improvement of heated and unheated meat products

  • improved sliceability and spreadability depending on the product
  • a more solid structure of every line product
  • no discoloration of the cutting surface
  • longer product storage in ordinary refrigerator thanks to stable pH buffer value

economic improvement

  • Application of Bufferliquid Extract® doubles shelf life and increases the final profits by 1% thanks to improved moisture binding

Bufferliquid Extract® is a patented product of and produced by PH Liquid Belgium Nv.
