Introduction. The research aim is to determine effect of duration of dehulling, the barley size and moisture, the rotation speed of abrasive discs, the abrasive grit and the load factor of the dehuller on the dehulling index. Materials and methods. The dehulling was carried out in laboratory dehuller (model ULZ-1) at the rotation speed of abrasive discs of 29.6±0.015 s-1 (1775±0.9 rpm) and 42.3±0.013 s-1 (2540±0.8 rpm) and removing of barley husks and meal was conducted in the laboratory aspiration duct of 60 mm width. Results and discussion. The research has shown that the increase in the dehulling duration the weight of the barley loaded to the dehuller, the rotating rate of abrasive discs and the load coefficient of the dehuller working chamber leads to the dehulling index rise. There exists the non-linear dependence between the load coefficient of the dehuller working chamber with the minimum point of the dehulling index for the large fraction of barley 0.27–0.28 and for the small fraction of barley 0.24–0.25. The influence of the barley weight and the load coefficient of the working chamber of the dehuller on the dehulling index occurs according to the curvilinear dependence with the minimum point of the dehulling index for the large barley fraction of 0.27–0.28 and for the small barley fraction of 0.24–0.25. The increase in the processing duration and the load coefficient of the working chamber of the dehuller leads to the increase of the dehulling index, but at the same time the minimum point of the dehulling index decreases from 0.29 to 0.25. As the size of the barley grows, the dehulling index decreases. The gain in moisture of the barley leads to the decrease of the dehulling index according to the linear dependence for both large and small barley fractions. Moreover, the small fraction has the bigger values of the dehulling index than the large one. The moisture influence on the dehulling index has linear dependence for both large and small barley fractions. As moisture increases the dehulling index decreases linearly, but at the same time the large barley fraction had lower values of the dehulling index than the small one. The increase in abrasive discs grit leads to the dehulling index decrease according to the curvilinear dependence. At the grit of 80 the dehulling index gets the constant value and its change depends on the duration of processing. Conclusion. The influence of technological parameters of barley grain on the dehulling index has linear dependence, and machine parameters affect the dehulling index according to curvilinear dependency. These results must be considered when evaluating the effectiveness of dehulling and the development of the process model.
介绍。研究目的是确定脱壳时间、大麦粒度和水分、磨片转速、磨粒和脱壳机负荷系数对脱壳指标的影响。材料和方法。在实验室脱壳机(ULZ-1型)中,研磨盘转速分别为29.6±0.015 s-1(1775±0.9 rpm)和42.3±0.013 s-1(2540±0.8 rpm),在实验室60mm宽的抽吸管中进行大麦壳和粗粉的脱壳。结果和讨论。研究表明,随着脱壳时间的延长、载于脱壳机的大麦重量、磨粒盘转速和脱壳机工作腔负荷系数的增大,脱壳指数均有所上升。大粒大麦0.27 ~ 0.28,小粒大麦0.24 ~ 0.25时,脱壳机工作腔负荷系数与脱壳指数最小值存在非线性关系。大粒大麦0.27 ~ 0.28和小粒大麦0.24 ~ 0.25时,大麦重量和脱壳机工作室负荷系数对脱壳指数的影响与脱壳指数的最低点呈曲线关系。脱壳机加工时间和工作腔载荷系数的增加导致脱壳指数的增加,但同时脱壳指数的最低点从0.29下降到0.25。随着大麦尺寸的增大,脱壳指数降低。大麦含水率的增加导致脱壳指数的降低,且大、小粒大麦的脱壳指数均呈线性关系。小馏分的脱壳指数比大馏分的大。水分对大、小粒大麦脱壳指数的影响均呈线性相关关系。随着水分的增加,脱壳指数呈线性下降,但大粒大麦的脱壳指数低于小粒大麦。磨粒粒度的增加导致脱壳指数呈曲线关系降低。在粒度为80时,脱壳指数达到恒定值,其变化与处理时间有关。结论。大麦籽粒工艺参数对脱壳指数的影响呈线性相关关系,机械参数对脱壳指数的影响呈曲线相关关系。在评价脱壳效果和建立过程模型时,必须考虑这些结果。

Introduction. The by-products from the processing of apples and grapes can be excellent materials for the production of functional foods. In this case, the environment is preserved, and food products are enriched with important nutrients. Materials and methods. A systematization of the latest scientific research in terms of management of the waste from the production of apple juice and grape wine. Results and discussion. By-products of apple and grape processing contain important nutrients such as fibers, minerals, vitamins, polyphenols, and possess high antioxidant activity. In recent years, a lot of research has been conducted to study the application of this type of waste in preparation of different food products (biscuits, cookies, cakes, bread, pasta, noodles, yogurt, cheese, kefir, salami, sausages, patties, and burgers). Regarding the percentages of substitution of conventional flours with by-products of apple and grape processing, variations are observed. For cereal products, the minimum percentage of substitution was 1% and the maximum was 100%. For meat products, the percentages of added by-products of apple and grape processing varied from 1 to 20%, while for dairy products, these contents were between the values of 0.2 and 10%. An improvement in nutrient quality with the addition of by-products of apple and grape processing was observed, such as increase of fiber, total polyphenol, flavonoids, anthocyanins and mineral contents and antioxidant activity. Incorporation of apple and grape processing by-products leads to changes of the volume or height of the products (biscuits, cookies, cakes, and bread), and changes in texture (hardness, crunchiness), appearance (surface properties, color, density), and intensity of smell and taste. It was found that the optimum cooking time of pasta/noodles/spaghetti decreased and cooking loss increased with the increasing amount of incorporated apple and grape processing waste. Addition of these by-products reduced fermentation time and syneresis during yogurt storage. It was found that the addition of by-products of apple and grape processing in the meat products increased cooking yield, emulsion stability, radical scavenging activity, and decreased pH. Conclusions. Use of waste from the processing of apples and grapes in the food industry is an opportunity to reduce environmental pollution, to create new functional and innovative food products, which will be enriched with important nutrients and biologically active substances.
介绍。苹果和葡萄加工的副产品是生产功能性食品的优良原料。在这种情况下,环境得到了保护,食品中也富含了重要的营养物质。材料和方法。对苹果汁和葡萄酒生产过程中产生的废弃物进行了系统化的最新科学研究。结果和讨论。苹果和葡萄加工的副产品含有重要的营养物质,如纤维、矿物质、维生素、多酚,并具有很高的抗氧化活性。近年来,人们进行了大量的研究,研究这类废物在制备不同食品(饼干、饼干、蛋糕、面包、面食、面条、酸奶、奶酪、开菲尔、腊肠、香肠、肉饼和汉堡)中的应用。关于用苹果和葡萄加工的副产品替代传统面粉的百分比,观察到变化。谷类产品的替代率最低为1%,最高为100%。对于肉制品,苹果和葡萄加工的副产品添加百分比在1%至20%之间,而对于乳制品,这些含量在0.2至10%之间。添加苹果和葡萄加工副产物后,纤维、总多酚、黄酮类化合物、花青素、矿物质含量和抗氧化活性均有所提高。苹果和葡萄加工副产品的掺入导致产品(饼干、饼干、蛋糕和面包)的体积或高度发生变化,质地(硬度、松脆度)、外观(表面特性、颜色、密度)以及气味和味道的强度发生变化。结果表明,随着苹果和葡萄加工废弃物掺入量的增加,面食/面条/意面的最佳蒸煮时间缩短,蒸煮损失增大。添加这些副产物减少了发酵时间和酸奶储存期间的协同作用。结果表明,在肉制品中加入苹果和葡萄加工副产物可提高蒸煮率、乳液稳定性、自由基清除能力和降低ph值。在食品工业中利用苹果和葡萄加工产生的废物是减少环境污染,创造新的功能和创新食品的机会,这些食品将富含重要的营养物质和生物活性物质。

Introduction. The aim of the present study was to investigate the effect of rosehip flour on some properties of wheat dough and bread. Materials and methods. Bread was prepared from wheat flour with the addition of rosehip flour in the amount of 5, 10 and 15% to replace the equal amount of the wheat flour. The used methods are standardized and generally accepted for evaluation of bread. Results and discussion. It was found that the addition of different amounts of rosehip flour to wheat flour affected the intensity of gas formation, as the percentage of rosehip flour added had increased, the intensity of gas formation decreased. When adding 5% rosehip flour, there was no significant deterioration of gas formation. Incorporation of rosehip flour into wheat dough resulted in a decrease in water absorption and degree of softening and the lowest results were found in the sample with 15% rosehip flour added. In terms of dough development time and consistency, there were no significant differences between the samples. Dough stability was found to be higher in the samples containing rosehip flour, with the highest value reported for the sample with 5% rosehip flour. Dough and bread color characteristics decreased with increasing the rosehip flour quantity. Darker colour of rosehip flour enriched samples could be due to the original colour of rosehip fibre, which is rather brown and slightly reddish. The substitution of wheat flour with rosehip flour resulted in a decrease in volume, specific volume, height/diameter ratio and baking loss of the wheat bread. Some of the sensory parameters of bread (crust color, aroma and taste) in the rosehip flour supplemented samples were rated higher by the panelists compared to the control sample, regardless of the amount of rosehip flour added. Conclusions. The rosehip flour could be successfully used as an additive in wheat bread formulation. In the sensory assessment bread samples with rosehip flour in terms of some properties such as crust color, aroma and taste had higher scores than the control sample.
介绍。本研究的目的是研究玫瑰果粉对小麦面团和面包某些特性的影响。材料和方法。以小麦粉为原料,分别添加5%、10%和15%的玫瑰果粉代替等量的小麦粉制成面包。所使用的方法是标准化的,并被普遍接受用于面包的评价。结果和讨论。结果表明,在小麦粉中添加不同量的玫瑰果粉对发酵成气强度有影响,随着玫瑰果粉添加量的增加,发酵成气强度减小。当添加5%玫瑰果粉时,气体形成无明显恶化。在小麦面团中加入玫瑰果粉会降低面团的吸水率和软化度,其中添加15%玫瑰果粉的面团吸水率最低。在面团发育时间和稠度方面,不同样品间差异不显著。在含有玫瑰果粉的样品中,发现面团稳定性更高,其中含有5%玫瑰果粉的样品报告了最高的值。随着玫瑰果粉用量的增加,面团和面包的颜色特性降低。富含玫瑰果粉的样品颜色较深可能是由于玫瑰果纤维的原始颜色,偏棕色和微红色。用玫瑰果粉替代小麦粉后,小麦面包的体积、比容、高径比和烘烤损失均有所降低。与添加玫瑰果粉的量无关,小组成员对添加玫瑰果粉的样品中面包的一些感官参数(面包皮的颜色、香气和味道)的评价高于对照样品。结论。玫瑰果粉可成功地作为小麦面包配方的添加剂。在感官评价中,添加玫瑰果粉的面包样品在皮色、香气和口感等方面的得分均高于对照样品。

Introduction. The research is devoted to the determination of effective display frequency of advertised communication messages to consumers in representative samples of the brewing industry to optimize the media budget. Materials and methods. The study is based on the scientific research of scientists on the development of beer market and digital economy, theories of advertisement message frequency, marketing research of brewing enterprises and their brands to determine the minimum range of effectiveness of advertised messages to beer consumers. Results and discussions. The frequency of displaying the communication message determines not only the effectiveness of appeals to the consumer, but also spending on media budget, however, currently there is no single point of view to this problem in scientific research. Both an insufficient amount of appeals and an excessive frequency lead to insufficient budget using. Effective frequency of the message influences not only on consumer’s purchasing behaviour and indicators of brand’s health but also allows to optimize media budget. Certainly, most media planners use the effective frequency strategy «three plus». In order to determine the frequency of communication with consumers for instruments of online-advancement of beer the modified Matrix of Ostrow is given. The blocks of factors of influence on beer promotion on the consumer market are improved, they are «Market factors», «Factors of quality of advertisement message», «General media factors». «Online media factors» block is added, where such indexes as description of placement the resources, use of social media, use of video formats, use of non-standard displays and formats, coverage of media channel, type of placement, accordance to general content of campaign are considered.

介绍。本研究以酿酒行业的代表性样本为研究对象,确定广告传播信息对消费者的有效展示频率,以优化媒体预算。材料和方法。本研究基于科学家对啤酒市场和数字经济发展的科学研究、广告信息频次理论、酿酒企业及其品牌的市场调研,确定广告信息对啤酒消费者的最小有效范围。结果和讨论。传播信息的显示频率不仅决定了对消费者的诉求效果,也决定了媒体预算的支出,但目前在科学研究中对这一问题还没有单一的观点。申诉数量不足和次数过多都会导致预算使用不足。信息的有效频率不仅影响消费者的购买行为和品牌健康指标,还可以优化媒体预算。当然,大多数媒体策划者使用有效的频率策略“三加”。为了确定啤酒在线销售工具与消费者的沟通频率,给出了修正的奥斯特罗矩阵。完善了啤酒在消费市场推广的影响因素板块,分别是“市场因素”、“广告信息质量因素”、“一般媒体因素”。添加了“在线媒体因素”块,其中考虑了诸如资源放置描述,社交媒体的使用,视频格式的使用,非标准显示和格式的使用,媒体渠道的覆盖范围,放置类型,根据活动的一般内容。以市场上大多数啤酒品牌为例,对改进后的矩阵进行了适应,因此对传播信息的有效重复频率进行了比较,从而可以将品牌从进一步收费的策略位置到广告信息在互联网上的放置位置分为4组。结论。在规划传播信息的频率时,建议使用自适应矩阵确定啤酒品牌与消费者的有效传播频率,以优化媒体市场。

The research is devoted to the determination of effective display frequency of advertised communication messages to consumers in representative samples of the brewing industry to optimize the media budget. Materials and methods. The study is based on the scientific research of scientists on the development of beer market and digital economy, theories of advertisement message frequency, marketing research of brewing enterprises and their brands to determine the minimum range of effectiveness of advertised messages to beer consumers. Results and discussions. The frequency of displaying the communication message determines not only the effectiveness of appeals to the consumer, but also spending on media budget, however, currently there is no single point of view to this problem in scientific research. Both an insufficient amount of appeals and an excessive frequency lead to insufficient budget using. Effective frequency of the message influences not only on consumer’s purchasing behaviour and indicators of brand’s health but also allows to optimize media budget. Certainly, most media planners use the effective frequency strategy «three plus». In order to determine the frequency of communication with consumers for instruments of online-advancement of beer the modified Matrix of Ostrow is given. The blocks of factors of influence on beer promotion on the consumer market are improved, they are «Market factors», «Factors of quality of advertisement message», «General media factors». «Online media factors» block is added, where such indexes as description of placement the resources, use of social media, use of video formats, use of non-standard displays and formats, coverage of media channel, type of placement, accordance to general content of campaign are considered.
