Ultrafiltration Process

Мембранные процессы широко внедрены на современных предприятиях молочной промышленности, поскольку они способствуют обеспечению максимальной степени использования сырья и повышению качества готовой продукции. При этом они без затруднений интегрируются в классическую технологическую цепочку. Научные изыскания, направленные на дальнейшее совершенствование технологий баромембранного концентрирования молочного сырья, а также использование генетического подхода к формированию его технологических свойств весьма актуальны. Целью данной работы являлось исследование закономерностей процесса ультрафильтрации обезжиренного молока, полученного из молока коров с генотипами АА и ВВ по гену CSN3. Объектом исследований служило обезжиренное молоко, полученное из молока от КРС черно-пестрой породы с гомозиготными генотипами по гену CSN3 (АА и ВВ). Концентрирование молока осуществляли на пилотной установке с полиэфирсульфоновыми мембранами с порогом задержки по молекулярной массе 50 кДа при температуре 15…20 °С и объемном факторе концентрирования 3,5. В результате исследований выявлена закономерность снижения скорости процесса ультрафильтрации вследствие большей эффективности концентрирования массовых долей белка и сухих веществ обезжиренного молока, полученного из молока коров с генотипом АА по гену CSN3, по отношению к молоку от коров с генотипом ВВ. Membrane processes are widely used in modern dairy production, as they help to maximize the use of raw materials and improve the quality of end product. At the same time, they are easily integrated into the classical technological chain. Further improvement of the baromembrane concentration of dairy raw products technologies and the use of the genetic approach to the formation of its technological properties is an urgent scientific study today. The aim of this work was to study the regularities of the ultrafiltration process of skim milk obtained from the milk of cows with genotypes AA and BB according to the CSN3 gene. The object of research was skim milk obtained from milk from black-and-white cattle with homozygous genotypes for the CSN3 gene (AA and BB). Milk concentration was carried out on a pilot plant with polyethersulfone membranes with a retention threshold in molecular weight of 50 kDa at a temperature of 15…20 °C and a volumetric concentration factor of 3.5. As a result of the research, a regularity of the decrease in the rate of the ultrafiltration process was revealed due to the greater efficiency of concentration of mass fractions of protein and dry matter of skim milk obtained from milk of cows with the AA genotype according to the CSN3 gene in relation to milk from cows with the BB genotype.

Abstract. The investigations were carried out in the year 2001 on 167 Black-and-White cattle farms of Wielkopolska region (West Poland). On the farms included in the study a survey on performing the premilking procedures was conducted and the results were collected concerning analyses of bulk tank milk samples for the somatic cell count (SCC) and total microorganism count (TMC). Herds, in which udders and teats were cleaned with a towel soaked with a disinfectant or washed with water containing a disinfectant, were characterized by lowest logeSCC (12.36 and 12.41, respectively). They were followed by herds in which wiping with a dry towel (12.48) and washing with clean water (12.58) were practiced. The lowest logeTMC was observed in the herds in which udders and teats were cleaned with a dry towel (10.66). This characteristic was similar in the herds where washing with clean water or wiping with a towel soaked with a disinfectant were practiced (10.89 and 11.00, respectively). The highest value of logeTMC was in the herds in which washing with water containing a disinfectant was practiced (11.28). For SCC, a significant interaction was found between both pre-milking procedures. In the case of wiping with either a dry or wet towel, significantly lower values of logeSCC were observed in the herds in which forestripping was performed prior to cleaning. However, in the herds in which udders and teats were washed with water, a better option was to perform forestripping after udder and teat cleaning.

The main purpose of this research was to observer effect co-solvent type (n-Hexane, chloroform and without co-solvent)  toward yield and quality of biodiesel via in situ transesterification process using microwave irradiation. The process was studied at microwave power 450 watt, reaction time 4 minutes, methanol to seed ratio 25:1 and catalyst concentration 5%. The physicochemical parameters of the biodiesel produced such as viscosity, density and acid value were analysed and compared with the SNI 7182-2012 standard. The experimental result showed the maximum yield biodiesel 78,32% obtained by using co-solvent chloroform.Test result of physicochemical properties (viscosity, density and acid value) of biodiesel products using co solvent n-Hexane, chloroform and without co solvent showed that these products conform to the SNI 7182-2012 standars. The type of co-solvent only affectedon biodiesel yield dan not affected on biodiesel quality (viscosity, density and acid value).  ABSTRAKTujuan penelitian ini adalah untuk mempelajari pengaruh jenis co-solvent (n-Hexane, chloroform dan tanpa co-solvent) terhadap rendemen dan mutu biodiesel secara trasesterifikasi in situ menggunakan radiasi gelombang mikro.
