The effect of hops (Humulus lupulus) on the quality of meat products was studied in connection with current demands for the wider usage of natural compounds in the food industry. Various additions of hop extracts were tested in heat-treated meat products under industrial conditions. The following technological properties were measured: colour (reflectance spectrophotometry), pH, water … [Read more…]
Sodium chloride is a traditional food additive that contributes to microbial stability, has a positive effect on the structure of meat products and is responsible for their salty taste. A number of negative effects on human health are, however, linked to excessive intake of sodium, for which reason various possibilities for reducing its intake are … [Read more…]
Excessive intake of sodium has been criticised due to its negative influence on human health, and for that reason ways are being sought to reduce its content or replace it in foods. The objective of this study was to investigate the partial replacement of sodium chloride in meat products with potassium chloride and potassium lactate. … [Read more…]
This paper investigates the use of the DART ionisation technique for meat freshness evaluation. Top round beef steak was cut into 50 g chunks and packed in a modified atmosphere. Five different extraction reagents were used for the extraction of low-molecule substances. The extracts were subsequently measured using the DART technique in combination with TOF-MS … [Read more…]
Ice crystals formed during the freezing process damage mitochondria in muscle tissues from which enzymes such as aconitase are released, and their activity may therefore serve as an indicator of previous meat freezing. Aconitase activity was investigated spectrophotometrically in the exudate released from meat samples during refrigerator and freezer storage. This method proved to be … [Read more…]
The quality of pork lard is closely related to several factors that affect the composition of fatty acids and therefore has a direct impact on the technological properties of the lard, especially the formation of soft lard, and causes problems during the production of dried sausages. A methodology of sampling lard from suppliers was developed, … [Read more…]
