Topicality.The popularity of coffee industry is high. This business is actively developing in Ukraine. A coffee shop is an establishment where the high quality of the product, as well as the development of coffee consumption culture are always in the first place. An important component is the commercial activity on which the coffee industry is built. This is an indicator of the right culture: more often Ukrainians prefer coffee in some cafe or restaurant, or even takeaway, instead of home or office coffee. However, COVID 19 pandemic affected the decrease in visits by Ukrainians to coffee shops, cafes, restaurants and other catering establishments. The main share of coffee consumption is an imported product. Ukrainian production is formed by manufacturers who import coffee beans as a raw material, and in Ukraine they roast, receive, package, produce an article without caffeine, and sell it under their own brand. The fiercest competition is typical in low segments of coffee drinks and grains. The aim of the study and its methods. The purpose of this article is to analyse the current state of Ukrainian coffee industry. When conducting the research, general scientific methods have been applied: scientific and theoretical elaborations of blighty and foreign scientists, informational materials of statistical and reference publications, analysis, synthesis, generalisation, comparison. Results. The article analyses the current state of coffee industry in Ukraine. The greatest producers of coffee and the most popular brands of grain and ground coffee in Ukraine have been characterised. The structure of coffee consumption in Ukraine by types and in quantitative indicators has been analysed. It has been noted that Ukrainian coffee industry is represented by a large number of small operators who open their mobile coffee shops in places with high traffic. This is due to small initial investments, a short payback period, and the possibility to change the location. Since the tendencies of the world coffee market have a significant impact on coffee industry in Ukraine, the demand is also growing steadily. The amount of coffee import in Ukraine exceeded the volume of exports. In 2020, the scope of export reached 15,0 million dollars, USA, while in 2021 it increased to 15,9 million dollars, USA. The amount of import increased from 251,3 million dollars, USA in 2020 to 266,7 million dollars, USA in 2021. The import of coffee beans is aimed at meeting domestic consumers’ needs. Ukraine is completely dependent on import, due to the non-compliance with natural and climatic conditions, because growing coffee on the territory of Ukraine is impossible. Conclusions and discussion. So, in the course of this study, it has been established that coffee industry in Ukraine is developing more actively and even creating competition. A significant place in the restaurant industry is occupied by coffee shops, which increase competition and increase the quality of provided servi
主题性。咖啡行业的知名度很高。这项业务正在乌克兰积极发展。咖啡店是一个始终将产品的高质量以及咖啡消费文化的发展放在首位的场所。咖啡产业的一个重要组成部分是商业活动。这是正确文化的一个指标:乌克兰人更喜欢在咖啡馆或餐厅喝咖啡,甚至外卖,而不是在家或办公室喝咖啡。然而,2019冠状病毒病疫情影响了乌克兰人去咖啡店、咖啡馆、餐馆和其他餐饮场所的次数减少。咖啡消费的主要份额是进口产品。乌克兰的生产是由进口咖啡豆作为原材料的制造商形成的,在乌克兰,他们烘焙、接收、包装、生产不含咖啡因的物品,并以自己的品牌销售。最激烈的竞争通常发生在咖啡饮料和谷物的低端市场。研究的目的和方法。本文旨在分析乌克兰咖啡工业的现状。在进行研究时,采用了一般的科学方法:国内外科学家的科学和理论阐述,统计和参考出版物的信息材料,分析、综合、概括和比较。后果本文分析了乌克兰咖啡工业的现状。乌克兰最伟大的咖啡生产商和最受欢迎的谷物和研磨咖啡品牌已经成为特色。分析了乌克兰咖啡消费的类型和数量指标结构。人们注意到,乌克兰咖啡业以大量小型运营商为代表,他们在交通繁忙的地方开设移动咖啡店。这是由于初始投资较小,回收期较短,而且可能会改变地点。由于世界咖啡市场的趋势对乌克兰的咖啡业产生了重大影响,需求也在稳步增长。乌克兰的咖啡进口量超过了出口量。2020年,美国的出口范围达到1500万美元,而2021年增加到1590万美元。进口额从2020年的25130万美元增加到2021年的26670万美元。咖啡豆的进口旨在满足国内消费者的需求。由于不符合自然和气候条件,乌克兰完全依赖进口,因为在乌克兰领土上种植咖啡是不可能的。结论和讨论。因此,在本研究过程中,已经确定乌克兰的咖啡业发展更加积极,甚至创造了竞争。咖啡店占据了餐饮业的重要地位,这增加了竞争,提高了服务质量。现代咖啡店是一种餐厅,在这里,咖啡的制作达到了一个新的水平,每一位客人都有自己的风格。目前餐饮业的机构类型是多业态的,因此创建一家全国性的咖啡店是我国的广告手段之一。有3-4个座位的咖啡馆在基辅越来越受欢迎。另一方面,最近流行的“即去即用”咖啡店正在失去其市场关键地位。咖啡行业的市场将增长,并在全面战争结束后趋于饱和。基础设施将得到恢复,乌克兰东部地区的餐饮业完全有机会得到发展。

Topicality. The article presents data and substantiates the feasibility of ultrasonic processing use while cleansing the carcass of commercially caught pond fish from scale on the example of carp.Purpose and methods. The aim of this research is to improve the process of cleansing carp Cyprinus carpio carcass from scale using ultrasonic processing by estimating the practical model that describes the relationship strength scale-skin fish. In the course of the study, analytical, theoretical and experimental methods have been applied, using control and measuring equipment of appropriate accuracy, standard methods for examining food raw materials, modern methods of mathematical statistics, correlation analysis, and computer technologies.Results. Based on the results of experimental data evaluation, the theoretical dependence of the scale-skin bond strength on the mass of pond fish carcass has been confirmed. The conducted experimental studies made it possible to determine the strength of the scale-skin bond for pond fish carcass in the native and chilled states, and to calculate, based on the experimental data, the value of the k3 coefficient for carp. While using this, it becomes possible to calculate the strength of the scale-skin bond for carcass of any weight group in theoretical way. Experimental studies gave an opportunity to fix the change in the strength of the scale-skin bond for carp carcass of industrial catch in conditions of storage in a chilled form. This dimension was found to vary a little, and the scale-skin bond strength in the native state could be used in order to elaborate the specification for the scale removal device. The dynamics of changes in the strength of the scale-skin bond under the influence of ultrasonic processing of fish raw materials was determined. It was revealed that the greatest influence on the change in the scale-skin bond was exposed to ultrasonic vibrations with a frequency of 22 kHz. So, the use of the specified frequency reduced the processing time by 27...34% for carp. This phenomenon can be explained by the fact that the selected frequency (22 kHz) has the highest oscillation amplitude of ultrasonic end of the emitter.Conclusions and discussion. It has been established that the ultrasonic frequency, the mass of fish carcass and the duration of processing have a decisive influence on the efforts of the scale-skin bond. The scale-skin bond ratio for Cyprinus carpio carp carcass in the native state was calculated, the value of which is 2.29. During the experimental studies, it was highlighted that the magnitude of the scale-skin bond coefficient for carp carcass changes insignificantly, and the strength of the scale-skin bond in the native state can be used to elaborate the terms of reference for the apparatus for removing scales. The greatest influence on the change in the scale-skin connection in conditions of ultrasonic processing was recorded at an oscillation frequency of 22 kHz. Prospects for furthe
主题性。本文提供了数据,并以鲤鱼为例,验证了超声波处理在清除商业捕捞的池塘鱼胴体水垢方面的可行性。目的和方法。本研究的目的是通过估算描述鳞皮鱼关系强度的实用模型,改进超声波处理鲤鱼胴体去鳞的工艺。在研究过程中,应用了分析、理论和实验方法,使用了适当精度的控制和测量设备、食品原料检验的标准方法、现代数理统计方法、相关性分析和计算机技术。后果根据实验数据评估结果,证实了鳞皮结合强度与池鱼胴体质量的理论相关性。通过所进行的实验研究,可以确定池塘鱼类胴体在自然和冷藏状态下的鳞皮结合强度,并根据实验数据计算鲤鱼的k3系数值。在使用该方法的同时,可以用理论方法计算任何重量组的胴体的鳞皮结合强度。实验研究为确定冷冻储存条件下工业渔获物鲤鱼胴体结皮强度的变化提供了机会。发现该尺寸变化不大,可以使用天然状态下的结皮强度来详细制定除鳞装置的规范。测定了超声波处理鱼类原料影响下鳞皮结合强度变化的动力学。结果表明,对水垢-皮肤结合变化的最大影响是暴露于频率为22kHz的超声波振动。因此,使用指定的频率使鲤鱼的加工时间减少了27%…34%。这种现象可以通过所选择的频率(22kHz)具有发射器的超声端的最高振荡幅度来解释。结论和讨论。研究表明,超声波频率、鱼体质量和加工时间对鳞皮结合的效果有决定性影响。计算了鲤鱼胴体在自然状态下的鳞皮结合率,其值为2.29。在实验研究中,人们强调,鲤鱼胴体的鳞皮结合系数的大小变化不大,并且鳞皮结合在自然状态下的强度可以用来详细说明除鳞装置的参考范围。在22kHz的振荡频率下记录了超声波处理条件下对水垢-表皮连接的变化的最大影响。进一步科学研究的前景是发现实施一种从鱼鳞中清除鱼体的复杂过程,特别是去除鱼内脏,这可能会影响相应过程的能量含量和材料消耗的减少。

Topicality. In this article activities of collective accommodation facilities (CAF) in Ukrainian regions are analysed, in particular, hotel enterprises (accommodation fund). In the hotel market, the competition strengthening between hotels can be observed, that is from the world hotel concerns. Therefore, hotel enterprises are trying to increase their productivity and competitiveness by implementing effective organisation and management methods.Aim and methods. The aim of the article is to analyse activity of CAF, identify problems of effective hotel business functioning in Ukraine. General scientific methods are used in this study: information materials of statistical and reference publications, analysis, synthesis, generalisation, comparison.Results. Based on official data from the State Statistics Service, it can be mentioned that for the period from 2018 to 2020 the number of similar accommodation facilities decreased from 4719 to 1337 un. Accordingly, the number of places in CAF also decreased from 300 010 to 155 029 un. in 2018–2020. The provided official data show a general decrease in the number of hotel rooms and similar accommodation facilities. A significant decrease in the number of hotels and similar accommodation facilities is observed in 2020 compared to 2018. The segment of five-star hotels has suffered more than four- and three-star ones, due to the sharp drop in the flow of foreign tourists to Ukraine. During 2018–2019, the development of collective accommodation facilities, owned by natural persons-individuals of business entities, has a positive tendency. In 2020, a significant amount of accommodation fund is observed in hotels in Kyiv, as well as in Lvivska, Odeska, Kyivska and Ivano-Frankivska regions.Conclusions and discussions. Thus, the study highlights that the reduced demand for hotel enterprises services in crisis circumstances is the main problem of hotel business development. It is necessary to develop infrastructure, introduce innovation and project support for the hotel enterprises development, implicate investments in the economic sectors progress. In comparison with other real estate sectors, double standards, a significant payback period of hotel enterprises hinder the hotel potential amplification in the country.
时事性。本文分析了乌克兰地区集体住宿设施(CAF)的活动,特别是酒店企业(住宿基金)。在酒店市场上,可以观察到酒店之间的竞争加剧,这是来自世界酒店的关注。因此,酒店企业正试图通过实施有效的组织和管理方法来提高自己的生产力和竞争力。目的和方法。本文的目的是分析CAF的活动,确定在乌克兰有效的酒店业务运作的问题。本研究采用了一般的科学方法:统计资料和参考出版物、分析、综合、概括、比较、结果。根据国家统计局的官方数据,可以提到的是,在2018年至2020年期间,类似住宿设施的数量从4719个减少到1337个。因此,CAF的名额也从30010个减少到155029个。在2018 - 2020年。所提供的官方数据显示,旅馆房间和类似住宿设施的数目普遍减少。与2018年相比,2020年酒店和类似住宿设施的数量大幅减少。由于前往乌克兰的外国游客急剧减少,五星级酒店比四星级和三星级酒店遭受的损失更大。在2018-2019年期间,由自然人或商业实体个人拥有的集体住宿设施的发展呈积极趋势。2020年,在基辅以及利沃夫斯卡、敖德斯卡、基夫斯卡和伊万诺-弗兰科夫斯卡地区的酒店中发现了大量住宿资金。结论和讨论。因此,研究强调危机环境下对酒店企业服务需求的减少是酒店经营发展的主要问题。有必要发展基础设施,引进创新和项目支持,为酒店企业的发展,在经济领域的投资进展。与其他房地产行业相比,双重标准、显著的酒店企业回收期阻碍了酒店在国内的潜力放大。
