Современные требования к рациональному питанию обусловливают производство жировых продуктов пониженной калорийности. Однако при их изготовлении производитель сталкивается с проблемами устойчивости процесса маслообразования, формирования структуры и качества продукта, решить которые возможно за счет использования стабилизаторов и эмульгаторов и корректировки режимов работы маслообразователя. С использованием программы онлайн-контроля изменения параметров работы маслообразователя и трансмиссионного электронного микроскопа при увеличении 6600 исследованы процессы формирования структуры и качества сливочного масла с жирностью 55%, выработанного из сливок с добавлением эмульгатора – моно- и диглицеридов жирных кислот в количестве 0,5% и комплексного стабилизатора консистенции на основе гуаровой и ксантановой камедей в количестве 0,2% – образец 1 и сухого обезжиренного молока, добавленного из расчета получения в готовом продукте 7,5% сухих обезжиренных веществ молока, – образец 2. Контрольным образцом было масло «Крестьянское» с жирностью 72,5%. Установлено, что процесс обращения фаз при изготовлении масла пониженной жирности происходит аналогично процессу при изготовлении масла с жирностью 72,5%. К особенностям процесса можно отнести формирование в качестве промежуточной структуры масляного зерна, а также повышение нагрузки на маслообразователь в момент переохлаждения сливок и удлинение продолжительности выхода на стабильный режима работы аппарата. Доказано, что для обеспечения устойчивой структуры продукта удельные затраты мощности должны быть увеличены на 9,8–13,2% при преобразовании сливок со стабилизаторами и эмульгатором (образец 1) и на 2,2–3,5% при преобразовании сливок с добавлением в качестве стабилизатора сухого обезжиренного молока (образец 2). Установлена возможность получения масла пониженной жирности с хорошей консистенцией и пластичностью. Modern requirements for rational nutrition determine the production of low-calorie fat products. However during their manufacture the manufacturer faces with problems of the stability of the butter formation process, the formation of the structure and quality of the product, which can be solved by using stabilizers and emulsifiers and adjusting the operating modes of the butter-forming agent. The processes of forming the structure and quality of butter with a fat content of 55% were studied using the online control program for changing the parameters of the butter-forming machine and transmission electron microscope at a magnification of 6600. Butter samples were developed from cream with the addition of an emulsifier – mono- and diglycerides of fatty acids in an amount of 0,5% and a complex consistency stabilizer based on guar and xanthan gum in an amount of 0,2% – sample 1 and skimmed milk powder added based on the calculation of obtaining 7,5% of skimmed milk solids in the finished product – sample 2. Butter «Krestyanskoe» with a fat content of 72,5% was the control sample. It is established that the process of phase reversal in the manufacture of low-fat butter is similar to the process for traditional types of butter. The formation of an intermediate structure of the butter grain, as well as the increased load on the butter-forming agent at the time of supercooling of cream and the lengthening of the duration of the stable mode of operation of the device can be attributed to the peculiarities of the process. It is proved that to ensure a stable product structure, the specific power consumption should be increased by 9,8–13,2% when converting cream with stabilizers and an emulsifier (sample 1) and by 2,2–3,5% when converting cream with the addition of skimmed milk powder as a stabilizer (sample 2). The possibility of obtaining low-fat butter with a good consistency and plasticity is established.

The present study, considering for the first time microbiological concerns due to the use of lemon albedo as a fat replacer, aimed at the selection of an anti-Listeria strain to be used as protective culture in low-fat southern Italian fermented sausages. In fact, these kinds of products require appropriate bio-protective strategies to avoid risks due to Listeria monocytogenes. Sixty-seven Lactiplantibacillus plantarum strains isolated from diverse sources were screened for their antimicrobial activity and their interaction with starter strains (Latilactobacillus sakei 152 and Staphylococcus xylosus MVS9). Lactiplantibacillus plantarum Lpls100, highlighting both listericidal activity and the ability to promote Staphylococcus xylosus MVS9 growth, was used as a protective strain in low-fat fermented sausages prepared with lemon albedo as a fat replacer. The effect of the albedo and the protective strain on the fermentation process and the final quality was ascertained. Results highlighted that the use of the albedo did not affect the growth of starter strains and enhanced some quality features, such as fatty acid profiles and certain sensory attributes. However, the albedo also produced a slow decrease in water activity, compromising the microbial quality. The anti-Listeria strain, enhancing coagulase negative cocci growth and exerting antimicrobial activity, avoided the inconveniences caused by the use of the albedo. Moreover, the anti-Listeria effectiveness was assessed through a challenge test using a Listeria cocktail. The study revealed that Lactiplantibacillus plantarum Lpls100, regardless of the presence of the albedo, assures a prompt inhibition of Listeria spp. Therefore, its use could be an important contribution to the quality of low-fat fermented sausages.

Abstract. Title of the paper: Growth, slaughter Performance and meat quality of pasture fattening calves raised on cattle out of the mother cows with beef cattle The production of calves raised on cattle depends on mother cows and the direct market. The calves mainly live on mother's milk, some cattle fodder and a little grain from the farm. Out of this reason and because of the high quality of the product it has a high reputation for the consumer. Some other advantages are for the method, the producer and the national economy because animals are used very young and though they decrease the mass of beef. The animals are slaughtered when they are dismissed. That's why pre-ripped breeds and their cross-breeding like Angus and Limousin are very suitable. The result of experiments shows that already with a slaughter age of seven–eight months you can reach a weight of 230–300 kg. With a slaughter yield of 56–58 % means this a warm weight of 140–180 kg. The valuable parts were 60–64 %. The good quality of the beef can be increased by a two weeks ripening of the meat. The consumers have a tends meat rich in protein and with a low fat content.

Abstract Background and Aims There is a lack of evidence-based dietary interventions in ulcerative colitis (UC) management. A diet high in fat and animal meat has been linked to an increased risk of UC. The aim of our study was to use a multilayered, multi-omic approach to comprehensively characterize the effect of a low fat, high fiber diet or a high fat diet in UC patients. Methods We enrolled patients with UC who were in remission or had mild disease with a flare within the last 18 months. We used a cross-over design in which patients received two dietary interventions: a low fat diet (LFD), containing 10% total calories from fat with an omega 6 to 3 ratio of below 3:1, and an idealized standard American diet (SAD), containing 35–40% total calories from fat with an omega 6 to 3 ratio of 20–30:1. Each diet was four weeks long with a two-week wash-out in between. The diet was catered and delivered to patients’ homes. Clinical symptoms, quality of life, and biochemical data were collected. Stool was collected for microbiome and metabolomic analyses. The primary endpoint was to determine adherence to a specified diet using catered meals; the secondary endpoint was to determine the clinical and subclinical effects of a low fat, high fiber diet or high fat diet in UC. Results Baseline diets varied widely but were generally lower in fiber as well as fruits and vegetables and higher in saturated fat than either of the study diets. There was a high rate of adherence to catered meals (SAD=86.68%, LFD=84.8%) with a 96.8% and 94.33% adherence to fat for SAD and LFD respectively. Patients that started in remission remained in remission (partial Mayo and sIBDQ). Following a LFD, patients saw a 20% improvement in their quality of life as measured by sIBDQ compared to their baseline. The effect of diet intervention on microbial diversity was reflected in the beta diversity with a significant increase in Faecalibacterium prausnitzii after LFD. CRP, sIBDQ, IL-6, and IL1β had a significant effect on overall gut microbiota composition as measured by Bray Curtis beta diversity (PERMANOVA)(P<0.007, P<0.001, P<0.021, P<0.048 respectively). The top taxa that contributes the most to this microbial variation from these clinical parameters was Faecalibacterium prausnitzii. Patients following a SAD had an increase in lauric acid, myristic acid, and N-oleoyl-L-phenylalanine with an increase in omega-6 metabolism pathways. Patients following a LFD had higher glycine, alanine, and phenyllactic acid with omega 3 metabolism pathways increased after LFD. Conclusions A low fat, high fiber diet is well tolerated and did not increase biochemical markers of inflammation. Catered meals and collection of microbiome, metabolome and biochemical data may allow early stratification of diet responders.

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

In this article a possibility of application of the ultrasonic non-contact method for assessing the quality of yogurt was researched. A prediction assessment was made by an ultrasound based on four parameters – pH, conductivity, fat content, and viscosity. An ultrasonic device was developed to determine the parameters of yoghurt by modified ultrasound sensor available commercially. In order to obtain data for post-processing, a software application was designed for recognizing the ultrasonic signal through the image processing and analysis techniques.<br>The developed algorithms and procedures were applied to determine the distance between the object and the sensor, whereby basic physico-chemical parameters of yogurt could be predicted with the lowest relative error. The working distance was 35 cm for the considered system. The survey results show that the parameters fat content, pH, conductivity, and viscosity of yogurt could be predicted by the proposed system for contactless measurement with accuracy of 94-97%.<br><br>

Experimental obesity was produced in DBA/2JN, STR/N and C57L/HeN mice as well as in Osborne-Mendel rats by several dietary regimens. One of these, containing 60% vegetable fat, increased the amount of degenerative joint disease in the rats and in two strains of mice. No increase of osteoarthritis occurred as a result of a 37.4% fat content in the diet, or from obesity produced by Ingle's diet, which has a relatively low-fat content. The mechanism by which the high-fat diet increased the joint disease is unknown, because neither obesity nor a high-fat diet alone had a deleterious effect on the articulations of the mice. Obese hybrid mice derived from a spontaneously obese and arthritis-prone strain (STR/1N) were resistant to articular degeneration. Dietary restriction of weight gain in the STR/1N mice failed to decrease the osteoarthritis in them.

Sala lauak is a traditional food that is easily found in West Sumatra. The development of sala leak products is carried out by reducing oil using gelatinization techniques. The process that occurs in gelatinization is when the starch granules are given water and heat, the starch granules will expand. This study aims to (1) develop sala lauak products by gelatinization techniques on oil absorption, (2) determine the organoleptic quality of sala lauak products by gelatinization technique processes, and (3) determine the fat content of sala lauak products by gelatinization technique processes. This research method is Research and Development (RnD). The results of this study in the organoleptic quality produced by sala lauak with pragelatinization flour showed a significant influence on the quality of inner texture, outer texture, taste, shape, and color. The same thing also happened to a significant reduction in fat content by three times lower using pregelatinized rice flour which is 7.4% compared to ordinary rice flour which is 25%. Kata kunci  :   Sala Lauak, Gelatinization Technique, rice flour.
