Abstract Soybean meal is one of the fodder components. It is a by-product of the production of soybean oil. Soybean meal is a specific cargo due to changes that may occur in it during transport processes. These changes are subject to many distinguishing features of usable quality inter alia fat and fatty acid content. The temperature and size of the soybean meal particles are among the factors influencing the transformations. The article presents the results of research on soybean meal and its individual fractions and the impact of selected indicators on the quality changes of this cargo. The results depend on the conditions corresponding to those that occur during the storage, handling and transport processes. The dependencies between them have been determined. The performed research allowed to determine the type and scope of changes taking place in this cargo under the influence of temperature. The results of the study showed that as the temperature rises, the fatty acid content in the soybean meal decreased during storage for a given period of 30 days.

<p style="text-align: justify;">Masyarakat Indonesia memiliki ketergantungan terhadap minyak goreng. Berdasarkan hal tersebut, perlu dilakukan penelitian tentang penggunaan dan mutu minyak goreng yang beredar di masyarakat khususnya pada <em>food court</em> Universitas Al Azhar Indonesia. Analisis penggunaan minyak goreng penjaja makanan dilakukan dengan melakukan survey. Untuk mengetahui kualitas minyak goreng, dilakukan analisis laboratorium yang meliputi pengukuran kadar air, kadar asam lemak bebas, dan bilangan Iod. Dari dua belas kantin, ada sembilan kantin yang menggunakan minyak goreng. Hasil analisis penggunaan minyak goreng, penjaja makanan secara konsisten  34% menggunakan minyak goreng bermerek dagang A. Pemilihan minyak berdasarkan warna dilakukan oleh 45% penjaja makanan. Berdasarkan frekuensi pembelian, 56% penjaja makanan membeli minyak per hari. Selain itu, 45% penjaja makanan menggunakan minyak dua kali pakai. Analisis kebutuhan minyak menunjukkan, 34% penjaja makanan menghabiskan 5 liter minyak per hari. Cara pembuangan minyak yang dilakukan oleh penjaja, 78% membuang minyaknya setelah digunakan, dimana 67% penjaja makanan membuangnya ke tempat sampah. Berdasarkan pengukuran kadar air, kadar asam lemak bebas, dan bilangan Iod menunjukkan bahwa minyak goreng yang digunakan belum memenuhi standar syarat mutu, walaupun kadar air yang masih di dalam ambang batas normal yaitu kurang dari 0,30%, namun kadar asam lemak bebas baik sebelum maupun sesudah penggunaan melebihi ambang batas normal yang didukung oleh hasil pengukuran bilangan Iod.</p><h6 style="text-align: center;"><strong>Abstract</strong></h6><p style="text-align: justify;">Indonesian society has dependence of cooking oil. Based on this condition, the analysis of cooking oil utilization and quality requirement at UAI food court is necessary and it was done. The analysis of cooking oil utilization was done by doing some survey. In order to search the quality of cooking oil, laboratory analysis was done that consist of water content, free fatty acid content, and Iod number. There are nine canteens from twelve canteens which utilize cooking oil. The result of cooking oil utilization analysis shows that 34% of merchant is utilizing A trade mark cooking oil, 45% is identifying cooking oil based on color. 56% is buying cooking oil per day, 45% is utilizing the cooking oil twice, 34% is spending 5 liters cooking oil per day, 78% is casting the cooking oil after utilize it, and 67% is casting the cooking oil into trash can. Based on the result of water content, free fatty acid content, and Iod number analysis showed that cooking oil is never fulfill normal limit, although the water content is still in proper limit is less than 0,30%, whereas free fatty acid content before or after analysis are very high and do not in proper limit and it is supported by Iod number measurement result.</p>

This study was carried out to evaluate the effect of replacing maize with low tannin sorghum (LTS) in layer feed on the physical and nutritional quality of eggs of layers at peak egg production stage. One hundred and twenty, 30-weeks old hens were grouped into three blocks of forty birds per block and were subjected to three different diets: 100%Maize, 50%Maize50%LTS and 100%LTS for 8 weeks. Eggs were collected on the 4th and 8th week of feeding trial. The results showed that eggs had statistically similar weights, amounts of protein, fat, Vitamin E and Vitamin A. The colour of egg yolks increased in lightness and reduced in hue and Chroma significantly across all the dietary blocks with increase in LTS while cholesterol content decreased. The saturated fatty acid content in the albumin and yolk oil extract remained constant irrespective of the period of feeding or variation of Maize and LTS content. The Monounsaturated fatty acid content decreased significantly (P=0.0003) during the whole trial diet period. The Polyunsaturated fatty acid content remained constant for the albumin (P=0.4095) while the yolk showed an increase (P=0.1162) from the initial 15.82±0.57 g/100g on the 4th week to 24.05±7.25 g/100g on the 8th week for diets with 100%Maize. 50%M50%LTS increased from 14.59±0.16 to 21.48±4.19 g/100g and 100%LTS had its Polyunsaturated fatty acid content decline from 13.36±0.31 to 10.71±0.32g/100g. This study indicates that LTS can replace Maize as a source of energy in chicken feeds with no adverse effects on the quality of the eggs.

The Impact

The variation in polyunsaturated fatty acid content of walnut (Juglans regia L.) oils was determined by analysis of samples isolated from specimens growing in four germplasm collections [California (55 cultivars), Washington (64 seedlings), China (12 cultivars), and France (20 cultivars)]. In addition, the impact of within-state geographic differences on oil composition was examined by comparing samples from three California cultivars (`Ashley', `Hartley', and `Franquette') grown in three locations. Local environmental effects on oil composition of `Chico' were also examined by comparing 1) samples collected from shaded and sun-exposed locations of the same trees and 2) samples collected from trees subjected to three irrigation regimes. Polyunsaturated fatty acid content, as a percentage of total fatty acids, ranged from 47.2% in nuts from PI 142323 from France to 81.0% in `Ashley' from California. However, our data indicate that environment, genotype, nut maturity, and their interactions all contribute significantly to variation in the degree of unsaturation of walnut oil.

Long Chain

Metabolism of long-chain polyunsaturated fatty acids derived from 18:2ω−6 and 18:3ω−3 by chain elongation – desaturation is essential for synthesis of complex structural lipids, leukotrienes, thromboxanes, and prostaglandins. These essential fatty acids are required for normal function in developing tissues and appropriate maturation of a wide variety of physiological processes. During development, fetal accretion of long-chain metabolites of ω−6 and ω−3 fatty acids may result from maternal or placental synthesis and transfer or, alternatively, from the metabolism of 18:2ω−6 and 18:3ω−3 to longer chain homologues by the fetus. After birth the infant must synthesize or be fed the very long chain polyunsaturated fatty acids of C20 and C22 type derived from 18:2ω−6 and 18:3ω−3.Metabolism of ω−6 and ω−3 fatty acids utilizes the same enzyme system and is competitive. When levels of dietary ω−3 and ω−6 C18 fatty acids are altered, the levels of metabolites of these precursor fatty acids change in specific brain membranes, influencing membrane lipid dependent functions. For example, a diet unbalanced in very long chain ω−3 and ω−6 fatty acids may increase brain membrane ω−3 fatty acid content when 20:5ω−3 is fed, while decreasing membrane fatty acid content of the ω−6 series of competing fatty acids. As 20:4ω−6 is quantitatively and qualitatively important to brain phospholipid, significant reduction in brain levels of 20:4ω−6 may be less than optimal. The impact of these compositional changes on brain function is not yet clear.The authors in this symposium address how this general area of essential fatty acid metabolism is relevant to the evolution of man, growth and development of fish, function of the retina and neural tissue, cognitive development of infants, and infant nutrition.
