Abstract

Abstract. The purpose of this study was to investigate the effect of boiling time using utensils made of different metal component on thenitrate and nitrite contentsin carrots. The carrots were obtained from Jaranguda Village, Karo Regency, North Sumatra. The utensil types used for boiling were made of stainless steel, what so called periuk and aluminum and boiling time were 5 minutes, 10 minutes and 15 minutes.The determination of nitrite was done by visible spectrophotometer using sulfanilic acid and N-(1-naphthyl) ethylenediamine dihydrochloride reagentsand absorbance was measured at a wavelength of 540 nm. The determinationof nitrate wascarried out by reducing the nitrate into nitrite using Zinc powder and diluted HCl then measured as nitrite. The nitritelevel was then convertedinto nitrate. The result showed that the utensil types and boiling time affected the levels of nitrate and nitrite in carrots. The nitrate and nitrite levels in fresh carrots was 32.14 mg/kg and 24.78 mg/kg respectively. After boiling for 5 minutes, the nitrate and nitrite levels decreased significantly. Further boiling of boiled carrots, the nitrite levelincreased in the aluminum utensil from 11.00 mg/kg to 20.15 mg/kg (83 %); in periuk from 9.18 mg/kg to 16.95 mg/kg (78%) andin stainless steelfrom 8.21 mg/kg to 11.75 mg/kg (43%). While the nitrate level decreased in aluminumutensil from 27.14 mg/kg to 21.08 mg/kg (22%); stainless steel from 16.40 mg/kg to 13.25 mg/kg (19%) and periuk from 20.30 mg/kg to 16.51 mg/kg (18%). The results of this study indicated that the nitrite level increased, while nitrate level decreased with boiling time.The effect of utensil type used on boiling increased nitrite but decreased nitrate level in carrotsand these effects were found that the mostinfluential treatmentwas using utensil made of aluminum.

Abstract

The nutritional value and biochemical properties of oil are measured by the fatty acids composition in oil and the position of fatty acids (sn-1,2,3) in the triacylglycerol (TAG) molecule. The purpose of this study was to measure the nutritional value based on the fatty acids composition of virgin coconut oil (VCO) and palm kernel oil (PKO), and the position of lauric acid in sn-2. The VCO used was VCO obtained from one of the Pharmacies store in Medan, and PKO from the Oil Processing Plant. The total fatty acid composition was measured by Gas Chromatography. The nutritional value of fat was evaluated by the percentage deviation from 33.33% (ratio: 1: 1: 1) of each group of fatty acid (saturated fatty acids; SFA: monounsaturated fatty acids; MUFA:polyunsaturated fatty acid (PUFA). The distribution of lauric acid in TAG was conducted through hydrolysis by using specific lipase enzymes active at sn-1,3 positions, so that free fatty acids and 2-monoacylglycerol were produced from one TAG molecule. Then free fatty acids were determined by Gas Chromatography. The distribution of lauric acid at sn-2 position was the difference between total lauric acid on TAG before hydrolysis and free lauric acid from sn-1.3 position after hydrolysis. The results showed that PKO nutritional value was better because of the smaller deviation (95.29%) compared with nutritional value of VCO with a greater deviation (118.55%). Lauric acid in sn-2 from VCO and PKO showed that the distribution of lauric acid in sn-2 position was not different,48.33and 48.59%. Keywords: virgin coconut oil, palm kernel oil, composition of fatty acids, sn-2 position, lauric acids

Abstract

Chemically, fat or oil is a mixture of triacylglycerol molecules, in which glycerol esterified with three fatty acids. Fatty acid is a monocarboxilic acid containing even number of carbon atom started from 4 to 22. Based on the length of fatty acid in triacylglycerol, fats and oils can be classified into two groups; medium chain triglycerides and long chain triglycerides. Coconut oil belongs to medium chain triglycerides oil because it’s fatty acids consist mostly of medium chain fatty acids (C4:0 to C12:0) and dominated by lauric acid (C12:0), hence usually called as lauric oil. In the year of 1950s, coconut oil was claimed that saturated fats, including coconut oil, could increase blood total cholesterol and hence is atherogenic, while unsaturated fats decrease total cholesterol. However, in 1990s, coconut oil was found to be different from the other saturated oils. Coconut oil composed of medium chain fatty acids with high amount of lauric acid. Coconut oil is metabolized differently from long chain triglycerides saturated oil, and therefore coconut oil has numerous beneficial nutritional values and health promotion. Consumption of food rich in medium chain fatty acids reduces the level of body fat and the decrease the risk of heart disease, diabetes, increase mother’s milk quality and active as potential antibacterial agent.

Abstract

Abstract. Dyslipidemia is a pathological condition characterized by increased levels of total cholesterol, triglycerides and LDL and decreased levels of HDL. Dyslipidemia causes cardiovascular disease risk factors by increasing cholesterol levels, increasing triglyceride levels, lowering HDL levels, and increasing LDL levels, as well as decreasing the proliferation of cardiac aortic cells in dyslipidemic rats. The pirdot plant (Saurauia vulcani Korth.) has long been known by the Simalungun, Toba and Karo communities to have the potential to treat various diseases caused by disruption of lipid processes in the body. Pirdot leaves contain bioactive compounds of flavonoids, tannins and saponins that have the potential to improve lipid profiles and prevent cardiovascular disease. This study aims to determine the activity of EEDP on the lipid profile of dyslipidemic rats. Pirdot leaf simplicia powder was extracted by maceration with 96% ethanol solvent and the extract was used on 30 dyslipidemic rats which were divided into 6 groups. Group 1 (Na-CMC), group 2 (Atorvastatin), group 3, 4, 5, 6 EEDP doses of 50, 100, 200, 400 mg/kg BW were administered orally for 21 days. At the end of the treatment, the levels of total cholesterol (TC) and aortic cell proliferation were measured. The results showed that Saurauia vulcani Korth had water content (6.23%), water soluble extract (10.50%), simplicia content soluble in ethanol (14.77%), total ash content (7.05%) and acid insoluble ash content (0.48%). From the antidyslipidemic study it was shown that EEDP 400 mg/kg BW improved blood lipand to increase aortic cell proliferation dyslipidemic rats was 69.84±0.27. Based on the explanation above, it is concluded that EEDP has an antidyslipidemic effect.

Abstract

A ketogenic diet consists of high fat, with moderate to low protein content, and very low carbohydrates, which forces the body to use fat instead of glucose to produce energy which is called ketosis. Ketogenic diets are commonly used in patients suffering from neurological disorders, and mostly epilepsy. Fat is a mixture of different triacylglycerol molecules formed by esterification of glycerol with three fatty acids. Based on the length of fatty acids in triacylglycerols, fats and oils can be classified into two groups; medium chain triglycerides composed of short and medium chain fatty acids containing 4 to 12 carbon atom, and long chain triglycerides composed of long chain fatty acids containing 14 to 22 carbon. Metabolism of medium chain triglycerides is different from that of long chain triglycerides. Classic or old ketogenic diet use long chain triglycerides as fat component may cause side effects such as dislipidemia and hence increase cardiovascular disease risk.This drawback may be reduced by replacing long chain triglycerides with medium chain triglycerides. Coconut oil belongs to medium chain triglyceride fats because it’s fatty acids consist mostly of medium chain fatty acids. There are two kinds of coconut oil obtained from coconut meat namely coconut oil used for frying, and virgin coconut oil is directly consumable and more suitable in Ketogenic diets

Abstract

Durian seeds, often regarded as agricultural waste, contain notable amounts of macronutrients, particularly proteins, that warrant further exploration for potential food and feed applications. This study aimed to evaluate the total nitrogen, protein, and non-protein nitrogen (NPN) contents in fresh and processed seeds of three local durian (Durio zibethinus) cultivars Bintana, Pelangi, and Bawor using the Kjeldahl method. Fresh seeds and their corresponding flours were analyzed for moisture content, total nitrogen, and protein fractions, including actual protein and NPN levels. The results revealed significant variations across cultivars and between fresh and processed samples. Bintana exhibited the highest protein content in both fresh and flour forms, followed by Pelangi and Bawor. Processing, including soaking, drying, and flour preparation, was found to increase measurable protein content but may also contribute to protein denaturation. Overall, durian seeds, particularly from the Bintana variety, demonstrate promising nutritional potential as a functional food ingredient or alternative protein source.
