Chemical Analyse

The purpose of this attemt was to evaluate the influence of deep-frying fat on the quality of frying pastry and observe chemical changes of frying fat during frying.The samples of frying pastry were provided by factory Penam s. r. o., Rosice. Four sorts of soft-centered friedcakes and not soft-centered friedcakes were evaluated. The samples of hydrogenated fat were taken twice always at the beginning and at the end of the frying. This lasted 7 days. Chemical analyse and qunatification fatty acid by using gass chromatography were took by these samples. The sensor eva­lua­tion was made by ten expert evaluators. Evaluators focused on following deskriptors: form, appearance, crumb, aroma, flavour of soft centred and flavour of product. We have found significant statistical differences between the products fried in the fat which was changed before and after the frying. The most differences were registered by porosity, plumpness, flavour of crumb and placement fill.Acidity number of fat increased linearly. Peroxid number decreased at the beginning and than increased again.

Feed determines the quality of pork meat, in which the composition of the fatty acid (FA) profile is one of the easiest to modify by the application of selected feed components. Barley grains are considered to have an impact on meat quality, including pork; however, there are still limited data on the use of hybrid barley in fattening pigs’ nutrition in relation to meat quality. The aim of this study was to determine the relation between meat quality, i.e., its oxidative stability, especially the FA profile, and fattening pigs’ diets with hybrid barley and/or wheat. In group I, hybrid barley (HB) composed 80% of the feed; in group II, a mixture of (40% each) wheat and barley was used; and in group III, wheat (W) composed 80% of the feed. Meat samples were taken from twelve randomly selected carcasses chosen from each group. The meat analyses covered the physicochemical and sensory traits. The results showed that the pork meat of fattening pigs fed fodder with 80% HB had decreased palmitic acid concentrations and increased oleic acid concentrations. The meat of these pigs was characterised by the best marbling, which was closely related to its juiciness after thermal processing and determined its final culinary quality. Moreover, the meat from these pigs exhibited a reddish colour, before and after thermal processing. In summary, the application of hybrid barley into pig nutrition improved the quality of the culinary meat.

Abstract Objectives Recent research indicates that the taste quality of fatty acids, called ‘Oleogustus’, differs from the traditionally accepted five basic tastes. However, the actual quality of the sensation has not been characterized. One question is whether there is a sour component because very short-chain fatty acids, like acetic acid, the sour tastant in vinegar, is structurally a fatty acid. The present study investigated the quality sensation of fatty acids of graded chain length. Methods Sensory stimuli were acetic acid, butyric acid, hexanoic acid, octanoic acid, decanoic acid, lauric acid, oleic acid, and linoleic acid emulsions and palmitic acid, stearic acid powder. The intensity of the samples before and after expectorating was measured. Next, participants repeatedly sipped, held for 5 seconds, and expectorated a sour solution (0.09% w/w) and rated the intensity on a gLMS until the intensity was lower than “weak”. After adaption to the sour solution, the intensity of the sample was measured before and after expectorating. Participants recorded the quality of each sample. Results The intensity of acetic acid was significantly lower after adaptation (P < 0.04) that before adaptation and a similar trend was noted for butyric acid. The other fatty acids were not affected by adaptation. The intensities of all liquid samples except the octanoic acid solution showed a significant difference between before and after expectorating the samples. The intensities of acetic, butyric and hexanoic acids were lower after expectorating the samples than the intensities before expectorating the samples (P < 0.05) while the intensities of decanoic acid, lauric acid, oleic acid, and linoleic acid (P < 0.05) were lower after expectorating. There was no significant difference in intensity of the palmitic acid solution and the intensity of the stearic acid solution between before and after expectorating. Conclusions The results showed that fatty acids with chain lengths great than 4 have a unique taste other than the sourness. In addition, short-chain fatty acid solutions had higher intensity before expectorating the solutions while the medium- and long-chain fatty acid solutions had higher intensity after expectorating solutions, indicating that there is a different persistence time for fatty acid directly related to chain-length.

Research on the antioxidant lycopene of tomato fruit (Solanum lycopersicum L.) blended in frying fat from catfish (Clarias sp) oil has been done. The purpose of this research is to determine the antioxidant activity of tomato lycopene before and after being grounded into frying fat and determine the quality of frying fat after being grounded with tomato lycopene. The antioxidant activity of tomato lycopene is determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Analysis of frying fat quality includes determination of pH, determination of FFA (free fatty acid) levels, determination of total fat content, measurement of water content, peroxide number and organoleptic observation. Antioxidant activity of tomato lycopen was very high, namely with inhibition value of 89.79%; 90.34%; 91.49% and 92.10%. Frying fat analysis showed high antioxidant activity of lycopene tomatoes with 50.67% inhibition; 51.63%; 51.39% and 51.23%. The results of the analysis of the quality of frying fat are nearly same with SNI quality standards, except for peroxide numbers. Keywords: tomato, lycopene, antioxidants, frying fat, catfish, DPPH

This study investigated the effect of vitamin B6 deficiency on the utilization and recuperation of stored fuel in physically trained rats. 48 rats were given either vitamin B6-deficient (B6–) diet or control (B6+) diet for 4 weeks and were trained on treadmill for 30 minutes daily. All animals were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The DE group was exercised on treadmill for 1 hour just before being sacrificed. Animals in the AE group were allowed to take a rest for 2 hours after being exercised like the DE group. Glucose and free fatty acids were compared in plasma. Glycogen and triglyceride were compared in liver and skeletal muscle. Protein levels were compared in plasma, liver, and skeletal muscle. Compared with the B6+ group, plasma glucose levels of the B6– group were significantly lower before and after exercise. Muscle glycogen levels of the B6– group were significantly lower than those of the B6+ group regardless of exercise. The liver glycogen level of the B6– group was also significantly lower than that of B6+ group during and after exercise. Before exercise, plasma free fatty acid levels were not significantly different between the B6+ and B6– groups, and plasma free fatty acid levels of the B6– group were significantly lower during and after exercise. The muscle triglyceride level of the B6– group was significantly lower than that of the B6+ group before exercise, and there were no differences between B6+ and B6– groups during and after exercise. Liver triglyceride levels were not significantly different between B6+ and B6– groups. Plasma protein levels of the B6– group were lower than those of B6+ before and after exercise. Muscle protein levels of the B6– group were not significantly different from those of the B6+ group. Liver protein levels of the B6– group were significantly lower than that of the B6+ group after exercise. Liver protein levels of both B6+ and B6– groups were not significantly changed, regardless of exercise. Thus, it is suggested that vitamin B6 deficiency may reduce fuel storage and utilization with exercise in physically trained rats.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.
