Abstract

The use of mangrove leaves as a functional ingredient is associated with secondary metabolites such as steroids, saponins, tannins, phenols, flavonoids, antioxidants, magnesium, sodium, potassium and calcium. This research determined the total phenol content (TPC), total flavonoid content (TFC) and antioxidants (IC50) in dry and fresh mangrove leaf infusion extracts. The method used was infusion extraction. The materials used are fresh mangrove leaves and dried leaves (dried in the oven). The data obtained then discussed descriptively based on the average obtained in the calculations. The research results showed that the type or condition of leaves used has an influence on TPC, TFC and Antioxidants (IC50). Oven drying can produce higher levels of secondary metabolites compared to fresh leaf infusion (TPC, 36 mg GAE/g; TFC 4.12 mg QE/g; IC50 225,706 ppm). Dried leaf extraction has better potential in producing secondary metabolic compounds and antioxidants. The choice of extraction method and type of solvent is highly recommended for further research objectives, because it suits research interests. It is recommended that when making functional drinks (tea) from mangrove leaves, to add other sources of ingredients such as dried lemon or mint leaves so that the resulting flavor is fresher and provides a better linking assessment of preferences.

Abstract

Jam is a processed food in a gel or semi solid food from fruit pulp with sugar, acid and food additives. Use of food additives with maximum threshold will effect in our body health. Beside of food additives, physical quality characteristics are also important to making the jam. The purpose of this study was to determine value of sodium benzoat, cyclamate, dossolved solids and water content based on merk and various commersial product of jam in Surabaya region. The research method was a descriptive observations with a total of 21 sample tested. The data in this study were analyzed descriptively and inferential statistics. From the research results, were obtained that 14,8% sample exceeds the threshold of sodium benzoat regulation, 61.9% had a little high water content, all of sample followed the regulation in cyclamate threshold and dissolved solids. The result show value of cyclamate was inversely proportional to dissolved solids. Differences in different brands and variants was not significant in the test results of sodium benzoat, cyclamate and water content. While in dissolved solids the brands provided significant different.

Abstract

The fiber content in empty oil palm bunches includes lignin (22.60%), pentosan (25.90%), cellulose (45.80%), and holocellulose (71.88%). The purpose of this study was to utilize empty oil palm bunch waste as a raw material for making cellulose acetate and produce a product in the form of biodegradable plastic by analyzing several test parameters such as tensile strength, elongation and biodegradability. The manufacture of biodegradable plastic uses the solution casting method with the initial step of cellulose synthesis from empty oil palm bunches followed by cellulose acetate synthesis and making biodegradable plastic. The combination of research treatments used was the percentage of glycerol of 3%, 4% and 5% and the percentage of cellulose acetate of 3% and 5%. The results showed that the best treatment obtained based on tensile strength, elongation and biodegradability testing was a sample with a mixture of 3% glycerol and 5% cellulose acetate (G3S5) with a tensile strength value of 2.39 Mpa, elongation of 25.2995% and biodegradability of 69.76% for 7 days.

Abstract

Yogurt is a fermented product that is popular and easily accepted by the public because of its benefits and good nutrition. However, the presence of lactose intolerance disorder caused by milk is an obstacle to getting the benefits of yogurt, so it is necessary to develop by using low-lactose milk in yogurt drink products . This research is an experimental study that aims to compare the nutritional content and sensory value of yogurt drink based on whole milk and low-lactose milk with the addition of L. Plantarum Dad 13. pH test, proximate analysis and sensory analysis of yogurt drink were carried out. The results showed that fresh milk yogurt drink samples had a lower final pH compared to samples using low lactose milk (p>0.05). Meanwhile, the low lactose yogurt had a lower sugar content compared to whole milk-based yogurt (p>0.05). Although the content analysis showed insignificant results, yogurt drink with the addition of L. plantarum Dad-13 showed good nutritional content compared to whole milk yogurt. Sensory test showed that probiotic yogurt drink tended to be preferred due to its flavor and higher acceptance level compared to whole milk yogurt.

Abstract

This study evaluated the effect of sugar concentration on the sensory quality of mango jam, including color, texture, aroma, and taste attributes. Four mango jam samples were tested by 30 panelist using the multiple comparison test method, namely two commercial standard samples (codes A and B) and two experimental samples (code 156 with 40% sugar and code 243 with 15% sugar). The evaluation result were analyzed using a two sample test at a significance level of 5% and 1%. Based on the calculation, the number of responses that A, as well as sample 156 and standard B did not reach the smallest number at the 5% level, indicating the the two experimental samples were not significantly different from their respective standard on all attributes tested.
