2、d wastes which would comply with environmental safety requirements. It was made a quality assessment in terms of content of polluting substances of cooking oil-production wastewater. For identification of fat content (phospholipids) of wastewaters, the thin-layer chromatography method was applied. T

3、he basis of the proposed method for purification of wastewaters was a preliminary separation of clarified and neutralized wastewater by dint of calcium carbonate, subsequently sodium hypochlorite for water clarification and its additional neutralization was used. The presented method allows reaching

A specific feature of such products is that they contain ingredients which, besides their traditional nutrient and energys upplying function, also possess a range of specific physiological functions which help human organism to combat negative influence of civilisation. 创造这种有用的、

7、健康的叫做功能性食品 的产品在二十一世纪成为一种食品工业上的主要发展趋势。这种产品的特征是包含了某些材料，除了具有提供传统养分和能量的功能，还具有一系列独特的生理功能，有助于人体对抗负面影响。 Food industry is one of the most resource-demanding branches of industry, therefore it is especially important to ensure rational usage of raw materials. In the processing sub-branches of agricultural co

8、mplex where the net value of products is comprised of material and energy expenditures, it is increasingly crucial to decrease the consumption of materials. This can be achieved by dint of wide implementation of non-waste technologies, complex usage of raw materials and secondary(recycled) resources

9、 in combined industry. Another important aspect of the subject problem is ensuring of ecological safety of plants where the food products are produced as well as elimination of the influence of the wastes upon the environment. One of the most important problems which the food industry enterprises fa

10、ce is the problem of wastewater treatment. In Ukraine, food-producing enterprises are mostly located in the West and the South-West which have a rich network of water bodies. This means that control over discharge of sewage water is to be exercised more strictly than usual and food-producing compani

11、es in these regions are to be prevented from polluting the water reservoirs. 食品 企业 是对资源要求最高的产业结构之一 ， 因此确保原材料的合理使用显得尤为重要。农业加工行业的净价值由原材料和能量支出决定，而且越来越多的决定于原材料的消耗。这就可以实现无废物生产技术、反复使用的原材料技术和使用二次 (再生 )资源技术的联合工业。食品工厂在产品生产和去除环境中废物的过程中的主要问题的另一个重要方面是确保生态安全。其中一个最重要的问题是企业面临的食品工业 污水 处理的问题。在乌克兰 , 食品生产企业主要分布在有丰富水体网

12、络的西部和西南部。这意味着控制排放的污水要比平时更严格地执行来避免食品生产公司在这些 地区污染水库。 Ukraine is one of the five main world producers of sunflower. Yearly output of sunflower amounted to more than 4 million tonnes in this year. Only Argentine (6.4 m tonnes) produced more. 乌克兰是世界五个主要向日葵生产地之一。今年向日葵的年产量达 400万多吨。比阿根廷 (6.4万吨 )所产生的多得多。 In

13、the latest years, Ukrainian vegetable oil market has become increasingly more integrated into the global vegetable oil market. This is due to the fact that processes of international division of labour get deepened and Ukraine is becoming one of the worlds leading producers of sunflower seeds, sunfl

15、cologically clean technologies whilst minimising the wastes of production. 因此 ,我们正在面临着一个重要的任务 , 更详尽地预测如此有价值的向日葵花油的产品特性，促进清洁生产同时减少产生的废料。 Sunflower oil, alongside other vegetable oils, possesses a number of useful properties which make its consumption a lot more preferable than consumption of animal f

16、at. 向日葵花油与其他植物油一样，拥有许多有益的特性，比很多动物脂肪消耗的更多。 With the purpose of further study of ecological influence of production of the cooking oil, assessment of the condition of sewage water, we shall examine the technology of oil production. 我们进一步对生产食用油产生的生态影响的研究是为了评估污水情况 ,检查技术食用油的生产工艺。 Extraction method is app

The fat which is produced in this manner must be cleansed of solvents and the fat is to be refined. 提取方法是 应用于溶解性脂肪如有机醚、环己烷和 戊烷 。这样产生的脂肪必须用溶剂清洗然后精炼浓缩。 The oil produced by way of pressing may be refined or not refined. But give

Because of this, scientists and specialists deem it that all kinds of oil must necessar

Depending upon the depth of purification, the following types of oil are produced: 食用油的提纯导致全部或部分的有害物质的被去除。取决于纯化的深度，以下类型食用油被生产 : non-refined (cleaned from mechanical admixtures) hydrated (cleaned from phosphatides) refined non-deodorised (cleaned from phosp

After the non-refined oil is separated from the raw material, it is to be filtered or left to settle, so that peelings, particles of seed coats, pu

The non-refined oil possesses colour, flavour, and smell which are peculiar to its mother raw material as well as all the corresponding substances (including the biologically active ones) which are native to it. 未精炼的 (来自机械压榨 ) 水合物 (来自磷脂 ) 精炼有臭味的 (来自磷脂，游离脂肪酸、着色剂 ) 精炼无臭味的 (从香料和芳

23、香物质 ,从杀虫剂和致癌物质清洗出来的精炼油 )。 未精炼的油从原料分离后，是过滤或沉淀下来，以便种皮 ,胚、果肉等可以去掉。有臭味的油具有的颜色、气味、味道都是独一无二的 ,其原料以及所有类似的物质 (包括生物活性物 )都是土生土长的。 Most of Ukrainian oil-producing enterprises do not provide for purification of industrial wastewaters, dumping thousands of tonnes of polluting substances into the water bodies. Th

24、e purification facilities which exist in some places were constructed a long time ago and had been designed with regard to the requirements of domestic wastewater purification. Such facilities, at best, partially decrease the value of general BOD (biological oxygen demand) or simply let the wastewat

Such industrial wastewaters are mostly polluted, especially with organic substances； therefore the purification facilities which are currently in operati

A significant ecological danger comes from the pollution of surface waters with organic substances which the wastewaters flowing from cooking oil-producing facilities contain. These substances, when dumped into water bodies, promp

For many enterprises of the subject branch, purification of wastewaters presents a serious problem. 乌克 兰 大部分的食用油生产企业不能净化

28、工业污水 ， 排放 成千上万吨的污染物质 进入水体。一些存在净化设备的地方是很久以前建立的而且是为生活污水净化而设计的。 这些设施即使在最好的情况下 也只能减少部分 BOD（生物需氧量）值或者仅仅是让水通过；最坏的情况是这些污水在排入水体前腐蚀这些设备并增强毒性。 这些工业 污水 大多受到污染 ，特别是有机物的污染；当前的净化设备不能达到卫生要求。 这些受食用油生产企业产生的有机物污染的地表水成为重大的 生态危机 。这些物质排放到 水体 中促进了腐烂 过程，病原菌污染了水体 ，导致水恶臭并且对动植物产生影响。 对 于许多企业， 污水净化成为一个严峻的问题 。 The purpose of th
