The butterfly pea flower extract was concentrated by vacuum evaporation and incorporated with supersaturated sugar solution (more than 90 Brix), agglomerated and dried at 60<sup>o</sup>C for 12 hours. &nbsp;The anthocyanin stability and antioxidant activity of the powder drink was evaluated for 28 days at three levels of temperature (room temperature, 40<sup>o</sup>C, and 50<sup>o</sup>C). The stability of anthocyanin decreased as the increase of storage temperature. The half-life of anthocyanin in the powder drink at respective temperature was 27.99, 16.53, and 9.81 days. Despite the anthocyanin significantly degraded, the decrease of antioxidant activity of the powder drink was not significant. Hence, the beneficial effect of the butterfly pea powder drink retained. </span></p> <p class="IJASEITAbtract"><span class="IJASEITAbstractHeadingChar"><span lang="EN-GB">&nbsp;</span></span></p> <p class="IJASEITAbtract"><span class="IJASEITAbstractHeadingChar"><span lang="EN-GB">Keywords</span></span><span lang="EN-GB">— anthocyanin; butterfly pea; co-crystallization; stability; sugar</span></p> 2020-07-31T00:00:00+07:00 Copyright (c) 2020 Indonesian Food Science & Technology Journal The Variuous Packaging Effects of Loker Telun Berasap Chili Damage During Storage 2020-08-07T16:00:50+07:00 Eva Salvia Lutfi Izhar Desy Nofriati <p><strong>General characteristics of fresh horticultural products like chili, is easily get damaged after harvest. The chili declining quality and loss after harvesting occur due to ongoing respiration process. Hence, the chilies become wither or rot. This damage happens due to physical, microbiological, and physiological influences. Physical damage and yield loss can be caused by packaging uses during storage. The study aimed to determine the effect of packaging use type for Locker Telun Berasap chillies on the weight loss and damage during storage. The treatments were the commonly community packaging use types which consists of: a) polyethylene plastic (PE), b) paper and c) banana leaf. Each treatment was performed two replications and stored at room temperature. Observation parameters during storage were weight loss, and physical, physiological, microbiological damages. The lowest weight loss percentage for 12 days’ storage by PE packaging was 45.5%. The total damage was 30% lower compared to paper and banana leaf packaging. Optimal freshness can be achieved until the 8th day of storage with physical damage only 1.03% on PE packaging. The results of the study showed that the dominant microbiological damage was found in the banana leaf packaging treatment.</strong></p> <p><strong><em><br></em> </strong></p> 2020-07-31T22:42:50+07:00 Copyright (c) 2020 Indonesian Food Science & Technology Journal Physical Properties of Edible Films from Pangasius catfish Bone Gelatin-Breadfruits Strach with Different Formulations 2020-08-07T16:00:48+07:00 Rian Adhi Santoso Yoni Atma <p><strong><em>Abstract</em></strong>— This research aims to provide edible film made from fish bone gelatin of Pangasius catfish mixed breadfruit starch with different formulations. The study was carried out through three stages including breadfruit starch isolation, edible films fabrication and analysis of physical properties of resulted edible film such as thickness, water vapor transmission, tensile strength and percent of elongation as well as moisture content. Edible films which were formulated from fish bone gelatin of Pangasius catfish by breadfruit starch addition have thickness values ranged of ​​0.084-0.123 mm, 6.08 - 16.77% of moisture content, water vapor transmission of 1.07 - 1.60 g/ m²/hour, tensile strength of 0.245 - 1.186 MPa, and percent of elongation around 70 - 87.14%. The edible films from gelatin of Pangasius catfish bone with breadfruit starch addition have physical characteristic which fulfill the standard requirements issued by Japanese Industrial Standard (JIS)</p> <p><strong><em>Keywords</em></strong>— edible film; biodegradable materials; fish gelatin;breadfruit starch; food packaging &nbsp;</p> <p>&nbsp;</p> 2020-07-31T22:46:29+07:00 Copyright (c) 2020 Indonesian Food Science & Technology Journal Performance Improvement of Fruit Ripeness Smart Label Based On Ammonium Molibdat Color Indicators 2020-08-07T16:00:45+07:00 Ade Iskandar Indah Yuliasih Endang Warsiki <p><strong>Research in fruit ripeness indicator is still experiencing especially due to major difficulties of several fruits with no color changes in its skin when it is ripen. From the previous research, there </strong><strong>was</strong><strong> found that ammonium molybdate [(NH<sub>4</sub>) 6Mo<sub>7</sub>O<sub>24</sub>.4H<sub>2</sub>O] embedded in the polymer matrix could be used as an indicator label to detect the ripeness of climacteric fruits base on the color change from yellow to blue and then green. However, the performance label still needs to be developed further. The surface of the label was still poor due to air or bubble trapping inside the film. It was found that mixing H<sub>2</sub>O<sub>2</sub> and molydate agent produced air or bubble thus in this research, a pre-treatment of film solution was done to chase away the air by storing and vacuuming the solution in </strong><strong>cold</strong><strong> temperature and time period of storage. A variety of film drying method was also carried out to find the best temperature of the oven to produce smooth surface of the film. The sensitivity of the label to ethylene gas was improved by adding more agent solution into the film. The best form of smart labels was produced using an oven at 40°C for 18 hours. The label composition </strong><strong>was</strong><strong> 100 mL distilled water, 3.5 g PVOH, 2 mL glycerol, and a color indicator solution (ammonium molybdate and hydrogen peroxide ratio of 1:10) at 4 mL. The molydate solution had to be stored for </strong><strong>3 days</strong><strong> in temperature of 7<sup>o</sup>C before used. The label sensitivity was improved as low as 100 ppm of pure ethylene gas. Label application </strong><strong>in a pack of </strong><strong>avocados show</strong><strong>ed</strong><strong> a relationship between label color changes and fruit quality degradation. </strong><strong>The value of hue label on days 0 to 6 changed from yellow to greenish yellow, while on the 7<sup>th</sup> to the 10<sup>th</sup> day the color of the label was still in the </strong><strong>same color as the day of 6<sup>th</sup></strong><strong>. Decreasing the quality of fruit during storage can be seen from the increase in the percentage of weight loss</strong><strong> and</strong> <strong>hardness of fruit </strong><strong>texture</strong><strong>. </strong></p> 2020-07-31T22:51:17+07:00 Copyright (c) 2020 Indonesian Food Science & Technology Journal
