Quality determination of vegetable oils used as an addition to fermented meat products with different starter cultures

Original language description

There were developed samples of fermented meat products of &quot;Mettwurst&quot; with an addition of a starter culture pentosacceus AS-3/100 or probiotic culture Lactobacillus casei Lc-01 and its combinations for this thesis. A part of animal fat was replaced with vegetable oils - sunflower oil and rapeseed oil. For comparison, there was also used a sample without an addition of vegetable oil. There were determined the characteristics of fats in samples: saponification value, acidity value, esteric, iodine and peroxide value. The samples were determined on the day of production and always once a week in a period of three following weeks. Every single sample was hereby determined 3 times. According to the results, it is more advantageous to use the samples with sunflower oil with an addition of specific cultures Lactobacillus casei Lc-01 and Pediococcus pentosaceus AS-3/100. The saponification value when adding sunflower oil detects that the quality of fat remains stable till the 14th day of storage (p &lt;0.05). The comparison of acid value detects that a sample with sunflower oil and culture Pediococcus pentosaceus AS-3/100 is more advantageous due to fast acidification in the first half of storage period. Good results of iodine and peroxide value had the variation of a sample with sunflower oil and a combination of both cultures. The variation of peroxide value maintained the lowest values. By using the samples with sunflower oil and unispecific cultures L. casei Lc-01 and P. pentosaceus AS-3/100, the culture P. pentosaceus AS-3/100, which remained stable till the 14th day of production, reached the best values of peroxide value. The sunflower oil is in spite of high content of PUFA more stable to which also contributes the increased content of vitamin E that works as an antioxidant here. The disadvantage of rapeseed oil is its higher susceptibility to oxidation. For reasons of faster decomposition of vegetable oils would be essential to cut down on the minimum durability. From the 14th day of storage, the content of free FA increases and the fat is still considerably quickly oxidized. The content of unsaturated FA, of which the vegetable fat is a source, quickly decreases. The sensory quality simultaneously decreases, too.
