Abstract

Purslane or krokot (Portulaca oleracea L.) can grow in warm climates (tropics and subtropics). Purslane plant is known to contain 41.4-66.4% of the omega-3 fatty acids, linolenic fatty acids (C18:3, n-3). Purslane extract contains unsaturated fatty acids, and more than 10 % consisted of alpha linolenic acid. This study is done to utilize purslane extract in candy jelly production that can be accepted by panelists. Maceration is used to extract purslane leave with three types of solvents (ethanol, ethyl acetate and hexane). The best extract was obtained by calculating the total yield and GC-MS analysis of purslane leaf extract components. The addition of purslane leaf extract to jelly candy uses concentrations of 0.5%, 1.0%, 1.5% and 2.0% (w/w). The observed parameters include physicochemical analysis (Total Dissolved Solids and pH), color, texture and sensory analysis. Selected jelly candies have a concentration of 0,5% purlsane leaf extract. Selected jelly candy has characteristics including ° Hue of 91.54 °, Total Dissolved Solids of 34.68 ° Brix, moisture content of 46.49%, fat content of 1.59%, protein content of 0.43%, ash content of 0.87 % and carbohydrate levels of 50.72%. Then based on the results of GC-MS analysis the selected jelly candy contains linolenic acid.

马齿苋(马齿苋)果冻糖制作中叶提取物的添加

马齿苋或马齿苋(马齿苋L.)可以生长在温暖的气候(热带和亚热带)。已知马齿苋植物含有41.4-66.4%的omega-3脂肪酸和亚麻酸(C18:3, n-3)。马齿苋提取物含有不饱和脂肪酸，其中-亚麻酸含量超过10%。本研究的目的是利用马齿苋提取物生产果冻糖，并得到小组成员的认可。用乙醇、乙酸乙酯和己烷三种溶剂浸渍法提取马齿苋叶。通过计算马齿苋叶提取物的总得率和GC-MS分析得到最佳提取物。马齿苋叶提取物在果冻糖中的添加浓度分别为0.5%、1.0%、1.5%和2.0% (w/w)。观察参数包括理化分析(总溶解固形物和pH值)、颜色、质地和感官分析。所选果冻糖的浓度为0.5%的荷叶提取物。所选果冻糖的°色度为91.54°，总溶解固形物白度为34.68°，水分含量为46.49%，脂肪含量为1.59%，蛋白质含量为0.43%，灰分含量为0.87%，碳水化合物含量为50.72%。然后根据气相色谱-质谱分析的结果，选定的软糖中含有亚麻酸。
