Current Trends

Wheat pasta is one of the most important cereal products and is becoming increasingly popular worldwide because of its convenience, simple formulation, long shelf life, and high energetic value. Wheat pasta is usually obtained from refined flour rich in carbohydrates but with low content of phytochemicals, micronutrients, and fibre. The increased demand of consumers for healthy foods has generated interest among both researchers and food producers in developing functional food products. This review showcases the current trends in pasta fortification. Changes in the nutritional value, cooking quality, sensory attributes, and antioxidant properties of durum and common wheat pasta enriched with both plant and animal raw materials are discussed.

Crude Enzyme Preparation

The enzymic degradation of wheat bran using cellulolytic and proteolytic enzymes from a number of sources was investigated. Two enzyme combinations were found to be effective for the chemical alteration of wheat bran. Crude enzyme preparation from the fungus T. viride in combination with a commercial proteinase brought about a 32% reducing sugar accumulation, a 36% loss of holocellulose, a 40% loss of α-cellulose and a, 54% solubilization of protein. Crude enzyme preparation from the fungus M. verrucaria in combination with a commercial proteinase gave rise to a 27% reducing sugar accumulation, a 39% loss of holocellulose, a 22% loss of α-cellulose and 50% solubilization of protein. The nutritional value for the rat of wheat bran modified by either enzyme combination was significantly improved. Apparent protein digestibility was improved significantly. Preliminary experiments indicate that the modification of wheat bran increases the metabolizable energy.

The influence of edible coatings based on cocoa leaf extracts on the ripening of ''Belle-Dame'' mangoes has been evaluated, to contribute to the improvement of the shelf life of these fruits after harvest. There were overall treatment-independent decreases in the firmness and chlorophylls levels, and increases in total soluble solids content, water content, physiological weight loss and β-carotene concentration during the ripening of mango fruits. These variations were very rapid in control fruits, reflecting an accelerated ripening process that led to the senescence of these fruits from day 9 after harvest onwards. In treated fruits, variations of different parameters were slow with significant differences between the treated fruits and controls. These inhibitory effects of coatings resulted in a delay of the ripening process and consequently to a shift of the onset of senescence to 12 days after harvest. In addition to the extension of shelf life by three days, treatments of mango fruits by dipping them in solutions containing cocoa leaf extracts induced a higher accumulation of β-carotene in coated fruits as compared to controls, thereby enhancing the nutritional value of the former.

The Impact

The baking of sourdough breads represents one of the oldest biotechnological processes. Despite traditionality, sourdough bread has great potential because of its benefits. Sourdough is a mixture of flour and water that is dominated by a complex microflora composed of yeasts and lactic acid bacteria that are crucial in the preparation of bread dough. Lactic acid bacteria cause acidification by producing lactic acid that increases the shelf life of bread by preventing the growth of undesirable microorganisms and affects the nutritional value of bread by increasing the availability of minerals. In addition to these advantages, the use of sourdough fermentation also improves dough machinability, breadcrumb structure and the characteristic flavour of bread. Lactic acid bacteria in sourdough fermentation are well known representing both homofermentative and heterofermentative bacteria. They may originate from selected natural contaminants in the flour or from a starter culture containing one or more known species of lactic acid bacteria. Sourdough can be cultivated in bakeries or obtained from commercial suppliers. However, many bakeries in Europe still use spontaneously fermented sourdoughs, which have been kept metabolically active for decades by the addition of flour and water at regular intervals. The impact of lactic acid bacteria on sourdough fermentation and their influence on dough and bread quality was discussed on the basis of research and literature data.

Wheat bran incorporation into biscuits may increase their nutritional value, however, it may affect dough rheology and baking performance, due to the effect of bran particles on dough structure and an increase in water absorption. This study analyzed the enrichment effect of wheat bran and arabinoxylans, the most important non-starch polysaccharides found in whole wheat flour, on dough rheology and thermal behaviour during processing of rotary-moulded biscuits. The objective was to understand the contribution of arabinoxylans during biscuit-making and their impact when incorporated as wheat bran. Refined flour was replaced at 25, 50, 75, or 100% by whole flour with different bran particle sizes (fine: 4% > 500 μm; coarse: 72% > 500 μm). The isolated effect of arabinoxylans was examined by preparing model flours, where refined flour was enriched with water-extractable and water-unextractable arabinoxylans. Wheat bran had the greatest impact on dough firmness and arabinoxylans had the greatest impact on the elastic response. The degree of starch gelatinization increased from 24 to 36% in biscuits enriched with arabinoxylans or whole flour and coarse bran. The microstructural analysis (SEM, micro-CT) suggested that fibre micropores may retain water inside their capillaries which can be released in a controlled manner during baking.

Current issue of today is the process of increasing the range of sausages and extending their storage time, especially for a boiled group of sausages. Therefore, the subject of research is pasteurized sausage, with an increased content of heme iron. The aim of the work was to create a complete product with high organoleptic characteristics, balanced according to biological and nutritional value and to select optimal thermal regimes to increase the shelf life of the product and to preserve the nutritional properties of the product, since cooked sausages have a limited shelf life, and due to properly selected heat regimes, we reach our goals. The receipts of sausages, based on meat of chicken-broiler using dry milk serum, collagen-containing preparation Scan-Pro, based on skin of pigs and micronized food cellulose with a definite level of hydration, a fat-based emulsion on the basis of chicken skins and a collagen-containing preparation Scan Pro and food blood. To increase the content of heme iron towards boiled sausages, food blood of pigs was added, in addition to increasing the nutritional and biological value of blood has a colorforming effect, with its introduction in an optimal amount, to achieve a characteristic color of sausage products. Sauce with the use of jelly-forming thickeners based on food hydrocolloids was added as a sauce. The value of the buffer capacity of the jelly after pasteurization was investigated. The basis for the production of pasteurized sausages was the technology of boiled sausages followed by heat treatment by pasteurization in order to provide an extended shelf life. Sausages were pasteurized at different temperature regimes. To determine the biological value of developed sausages, it was used the application program BIO1.bas. The chemical composition of sausages was modeled based on their functional and technological parameters. Physico-chemical, microbiological, organoleptic research of the product was carried out. The amino acid composition of the product was simulated, which allowed to mention upon the biological and nutritional value of the studied formulations.

Psychrotrophic microorganisms, especially Pseudomonas spp., are present in the microbiota of refrigerated milk as they can grow at refrigeration temperatures irrespective of their optimal growth temperature. Psychrotrophic counts ranging from 105 to 108 CFU/mL in refrigerated raw milk effect cheese quality, since the synthesized thermoresistant enzymes affect the nutritional value, sensory properties, and texture. Cheese is the dairy product with the highest growth rate in the food industry in Brazil in recent years and meets the current consumption trends of nutritious and practical foods. The objective of this review was to address the importance and influence of the psychrotrophic raw milk microbiota on the quality and sensory properties of cheese. The enzymes produced by psychrotrophic microorganisms lead to taste changes, undesirable clotting times, increased concentrations of free fatty acids and free amino acids, and a reduced shelf-life, in addition to negatively affecting cheese yields. Proteases from psychrotrophs are also associated with slicing problems and progressive loss of the elasticity of cheese, a bitter taste, and increased clotting times of cheese produced with pasteurized milk. On the other hand, their lipases increase the clotting time and have a negative effect on the sensory properties by providing a rancid, soap, metallic, or oxidized smell and taste. The control of the psychrotrophic population found in refrigerated raw milk contributes to better cheese production yields and desirable texture and sensory properties, which extends the shelf-life of cheese and improves consumer acceptance.
