Abstract

Pare (Momordica charantia L.) is a plant that grows in the tropics, namely Asia, the Amazon (South America), East Africa and the Caribbean. The bitter taste of this fruit gives rise to several benefits including stimulating appetite, curing jaundice, improving digestion. Bitter taste in bitter melon is caused by the content of momordicosides of the triterpene glucoside group or kukurtibacin. This study aims to determine the levels of flavonoids in bitter melon (Momordica charantia L.). The method used in this research is the maceration extraction method using ethanol as a solvent. The extraction results were analyzed qualitatively by adding Mg and HCl powder to determine the presence of flavonoid compounds. While the quantitative test was carried out using the differential pH method in an acidic atmosphere, namely at pH 1 and pH 4.5. Determination of flavonoid content of bitter melon extract using UV-Vis spectrophotometry at 520 nm and 700 nm wavelengths. The results obtained in the qualitative test showed that the bitter melon extract contained positive flavonoids. The results of the quantitative test showed that the total flavonoid content in the bitter melon extract was 0.41 mg/100 g.

Abstract

Kaledo (donggala ox leg) is one of the famous culinary in Central Sulawesi. The number of restaurants that provide kaledo menus causes problems, due to the lack of utilization of the bone waste, causing problems in the environment. People still don't know that beef bones still contain protein. Protein serves as a form of new tissue during the growth and development of the body. This study aims to determine the protein content of beef bones from kaleo waste from the city of Palu, Central Sulawesi, which was taken randomly from a kaledo restaurant. Determination of protein content in beef bones from kale waste using the Kjeldhal method. In the results of calculations that have been carried out with three repetitions, it was found that the protein content in Repetition1 was 3.85%, Repetition2 was 3.59% and Repetition3 was 4.2%. The average protein content of beef bones from kale waste is 3.88%. The results of this study are expected to be a source of information about the protein content contained in beef bones from kaleo waste and can be used further as a substance in the utilization of bone waste.

Abstract

Durian seed flour can be used for the manufacture of food products such as sticks and steamed sponges. Sticks and steamed sponge cake are foods that many people like from children to adults.  Durian seed flour is rich in minerals including magnesium, potassium, calcium and phosphorus. This study aims to determine the content of magnesium, potassium, calcium and phosphorus in food products from durian seed flour using Atomic Absorption Spectrophotometer (SSA) and UV-Vis Spectrophotometry.   The results showed that the magnesium content in the sticks of durian seed flour with formulation 1 (0% durian seed flour) amounted to 84,053 mg/kg, formulation 2 (50% durian seed flour) amounted to 145,213 mg/kg and formulation 3 (100% durian seed flour) amounted to 142,313 mg/kg.  Potassium content on sticks from durian seed flour with formulation 1 (0% durian seed flour) of 1,186 mg/kg, formulation 2 (50% durian seed flour) of 1,863 mg / kg and formulation 3 (100% durian seed flour) of 1,693 mg/kg.  The calcium content in steamed sponge from durian seed flour with formulation 1 (0% durian seed flour) of 30.37 mg/kg, formulation 2 (50% durian seed flour) of 37.84 mg/kg and formulation 3 (100% durian seed flour) of 35.84 mg /kg. While the phosphorus content n steamed sponge from durian seed flour with formulation 1 (0% durian seed flour) of 17.1 mg/kg, formulation 2 (50% durian seed flour) of 27.1 mg/kg and formulation 3 (100% durian seed flour) of 24.3 mg/kg.
