Extrusion cooking is a thermal process often practiced in food, chemical and feed industry. Due to extrusion, nutritive value, texture, sensor characteristics and hygiene are improved. The influence of extruded corn grain and bread improver quantity on rheological and sensory characteristics of bread was investigated in this paper. Experiment was planed according to factorial plan 32 with independent variables: Quantity of extruded corn (10-30 % based in wheat flour, variation interval 10) and improver (0-0.4 % based on flour, variation interval 0.2). The influence of extruded corn on Dough handling is illustrated by extensigraph data: In comparison to the dough without corn, area is decreasing 50 to 60 % and resistance to stretching 15 to 20 %. The addition of commercial bread improver, regardless the quantity of extruded corn is beneficial contributing to improved extensigraph data up to 30 %. By substituting wheat flour with 10 to 20 % of extruded corn along with proper quality of bread improver, bread quality is satisfying and stalling is significantly improved. In the production of so-called mixed corn bread (30 % of extruded corn) extrusion is contributing to retard stalling and prolonged shelf-life.

Selected indicators of the quality of processed milk are reviewed in three sections: indices of heat treatment, detection of adulterations and assessment of shelf life. The characterization of the thermal process to which milk was submitted can be achieved by measuring either the formation of new compounds (lactulose, furosine) or the degradation of thermolabile constituents (enzymes, whey proteins). The presence of certain compounds may indicate fraudulent additions committed for eco nomic reasons. Finally, residual or reactivated heat stable enzymes may cause serious storage defects in UHT milk and, therefore, the proteolytic and lipolytic activities and the degree of protein and lipid degradation are useful predictors of the shelf life. Different analytical methods for the determination of the selected quality indicators are also summarized.

The actual challenge for the food industry is the utilization of by-products of fruit and vegetable processing and their use in the production of enriched food products. It allows to use raw materials with a high content of biological active substances more efficiently and rationally. The possibility of using carrot bagasse as an ingredient in the preparation of extruded ready-to-eat product was studied. The wheat meal was used as core ingredient. The influence of the bagasse dosage on the extrusion conditions and the properties of the extrudates samples was studied. It was shown that an increase of the bagasse content more than 20% influenced the quality of the product negatively.The expansion index decreased more than 2 times and the bulk density increased by 40%. The method of additional steam venting from the middle part of the extruder chamber was investigated during the extrusion cooking of mixtures with the bagasse content more than 20% and moisture content 26.5, 28.9 and 34.5%.The indicator of the steam venting was the reduction of pressure in the degassing installation. As a result, the moisture content of the material in the die zone of the extruder chamber decreased. It was shown that additional steam venting during extrusion of high-moisture mixtures led to more severe extrusion conditions. The temperature, die pressure and torgue increased significantly. It imroved the quality of extrudates. Steam venting during extrusion of blends with 26.5 and 28.9% moisture increased expansion index more than 2 times and decreased the bulk density by 21-25%.Extrusion process of a mixture with a moisture content of 34.5% without and with steam venting was unstable and did not allowed to obtain samples of extrudates with acceptable quality. The proposed method for extrusion of high-moisture blend of wheat flour with carrot bagasse can be basis for developing technologies for the production of ready-to-eat extruded products using moist food by-products of fruits and vegetables processing.

Cookies are a popular confectionery product with a unique texture and taste, long shelf life and a relatively cheap price; therefore, it is a widespread snack among people of all generations. Nevertheless, cookies are usually made of wheat flour and most formulations are highly caloric and have a low fiber content. Soy flour is an excellent source of proteins, fibers, vitamins and minerals and it is being considered as a great supplement to wheat flour because it increases nutritive characteristics of the final product. By their digestibility and amino acid content, soy proteins are very similar to proteins derived from animals. They also contain many essential amino acids, which are deficient in most of the cereals. The purpose of this work was to determine the effect of soy flour on quality of cookies. Wheat flour was supplemented with 35% of soy flour (full-fat toasted, low-fat toasted, defatted lightly toasted, toasted and soy protein concentrate). The supplementation of wheat flour with soy flour had affected nutritive value and sensory characteristics of cookies.

Purpose Study on chia seeds is receiving increasing interest because of their nutritional and health-promoting properties that have been recognized by their high content of antioxidants, proteins, minerals and dietary fibers. Hence, the purpose of this study is to develop a value-added food product using chia seeds and to assess the nutritional properties, shelf life and consumer acceptability of the developed product. Design/methodology/approach Six different formulations of muffin mix were prepared by incorporating chia seeds with wheat flour in various ratios and evaluated for sensory characteristics. The nutritional components and shelf lives of the developed products were also evaluated. The developed product was stored for three months to assess the shelf life. Findings Results indicated that muffins made with chia seeds can be added up to 20% in wheat flour without affecting the sensory scores (p = 0.0014). Regarding nutritional evaluation, the results revealed that 20% incorporation of chia seeds significantly increased the total antioxidant activity (p = 0.001), increased the crude protein (p = 0.0001), fat (p = 0.0001) and crude fiber (p = 0.001) contents and lowered the carbohydrate (p = 0.0001) content when compared to the control sample. Muffin mix made with chia seeds had significantly higher mineral content (calcium, phosphorus, zinc and iron) than did the control. The developed product had a shelf-life stability of three months in terms of moisture content, peroxide value and total bacterial count and was well accepted by consumers. Originality/value Intrinsic characteristics of chia seeds can improve the quality of muffins and bring health benefits to the consumers.

The article focuses on the process of intensive mixing of liquid phase in the tin during high-temperature sterilization, i.e. sterilization when temperature of the heat carrier reaches 150-160°C. It has been stated that for intensification of the thermal process during sterilization of tinned fish with liquid filling it is preferable to turn a tin from bottom to top. This operation helps to increase the driving power of the process and to shorten warming time. Besides, high-temperature sterilization carried out according to experimental modes, where the number of tin turnovers is calculated, greatly shortens processing time and improves quality of the product. In this case there is no superheating, all tins are evenly heated. The study results will contribute to equipment modernization and to preserving valuable food qualities.
