Production Mechanisms

Lactic acid bacteria (LAB) have an essential role in the production of fermented products. With their metabolic activity, they influence the ripening processes - leading to desired sensory qualities while at the same time inhibiting the growth of undesired microorganisms. Because of their dominant role during fermentation and because of a long tradition of utilization, Lhave been designated as ?safe microbiota?. Biological protection of LAB, as a naturally present and/or selected and intentionally added microflora, is realized through the production of non-specific (lactic acid, acetic acid and other volatile organic acids, hydrogen peroxide, diacetyl, etc) and specific metabolites, bacteriocins. Bacteriocins are extracellularly released proteins or peptides which possess certain antibacterial activity towards certain types of microorganisms, usually related to the producing bacteria. Today, bacteriocins represent a very interesting potential for their application in the food industry. Their application can reduce the use of synthetic preservatives and/or the intensity of thermal treatment during food production consumer?s need for safe, fresh and minimally-processed food. With the intention of realizing this potential to the fullest, it is necessary to understand the nature of bacteriocins, their production mechanisms, regulations and actions, as well as the influence of external factors on the their antimicrobial activity. The composition of food, i.e. its characteristics (pH, temperature, ingredients and additives, types and quantities of epiphytic microbiota) and the actual technological process used in production, can all influence the stability and activity of the added bacteriocins. The future research in this field should also aim to clarify this unknown aspect of the application of bacteriocins, to provide the necessary knowledge about the optimization of the external conditions and open up the possibility of discovering their new producers.

Sensory Qualities

The aim of the work was determined of microbial and sensory quality of selected white yoghurts in the course of their shelf-life. The samples of yoghurts were produced in dairy Olma, joint-stock company Olomouc. The selected white yoghurts Revital Active (in addition of probiotic culture composed of Bifidobacterium sp., Lactobacillus acidophilus and Lactobacillus rhamnosus), Klasik, Bio yoghurt Via Natur, Silueta light (0.1% fat, sugarless) and Florian were assessed in fresh condition and after an expiration date. Total counts of microorganisms, lactic acid bacteria, yeasts, moulds and coliform bacteria have been checked in the samples of yoghurt. Texture, aroma, taste, acidity and total sensation were assessed by sensory analyse. Titrating acidity was carried out in accordance with CSN ISO 57 0530. The counts of lactic acid bacteria ranged from 105 CFU/g to 107 CFU/g and total counts microorganisms ranged from 108 CFU/g to 109 CFU/g at the beginning of best before date. The lowest counts of lactic acid bacteria were detected in Bio yoghurt (4.62 × 105 CFU/g). The counts of microorganisms in the samples of yoghurt were similar or with certain difference all the time of best before date. The counts of undesirable microorganisms (i.e. coliform bacteria, yeasts and moulds) weren‘t detected. Sensory assessment confirmed that white yoghurts are satisfactory and fulfil qualitative expectation also over all negative changes along storage.

The research was carried out within the framework of the theme of state assignment № 0593–2019–0008 «To develop theoretical foundations for creating composite mixtures for bakery products using physical methods of exposure that ensure homogeneity, stability of mixtures and bioavailability of nutrients, to optimize diets population of Russia». The data on the species belonging of new strains of lactic acid bacteria and yeast isolated from samples of good quality gluten-free starter cultures are presented. A comparative assessment of the antagonistic and acid-forming activity of strains of lactic acid bacteria and the fermentative activity of yeast was carried out. The composition of microbial compositions from selected strains of LAB and yeast was developed. The influence of the starter culture on the new microbial composition on the physicochemical, organoleptic indicators of the bread quality and resistance to mold and ropy-disease was investigated.
