Abstract

Consumption of white rice started to be reduced by diabetics to control the increase in blood glucose. Consumption of rice with IG value and low digestibility can be used as a solution for diabetics. Rice with low digestibility values can be produced by processing rice into instant blue rice using the autoclaving-freezing method and adding telang flower extract as a natural blue coloring and working as an antioxidant. The purpose of this study was to characterize the total levels of starch, amylose, amylopectin, starch digestibility (in vitro) and profile of starch hydrolyzed instant blue rice. The results showed that Membramo and Ciherang 40% instant blue rice had total starch characteristics 73.50% and 74.85%, amylose 22.06% and 25.94%, amylopectin 51.77% and 48.91%, starch digestibility 62.41% and 58.38%. The combination of autoclaving-freezing treatment with added telang flower extracts in both varieties can reduce total starch, amylopectin, and starch digestibility levels and increase amylose content. Decreased digestibility of starch in instant blue rice can reach 17.87% and can produce lower digestibility values compared to Basmati and Taj Mahal rice (comparative rice known as diabetic rice). The hydrolyzed profile of instant blue rice Membramo and Ciherang is lower than blue rice. Hydrolyzed starch profile Membramo instant blue rice is the same as Basmati rice but still cannot reach Taj Mahal rice, while Ciherang instant blue rice reaches Taj Mahal rice and is lower than Basmati rice. Therefore, Membramo and Ciherang instant blue rice has the potential to be an alternative food for diabetics and can also produce innovative food with a low digestibility value Keywords: Instant rice, autoclaving-freezing, telang flower extract

Abstract

Fruit leather is a fruit product that has been destroyed and then dried using an oven, so as to form a thin sheet that can be rolled. Fruit leather is generally a thin sheet with a thickness of 2-3 mm, 10-20% water content, plastis texture, was a consistency and a specific taste according to the type of fruit used. Ambon banana has a low pectin content that requires a gel-forming agent to produce the desired texture. One of the commonly used gelling materials is carrageenan. Carrageenan is one of the seaweed derived hydrocolloids that have the ability to form gel and can improved the texture of the product. Carrageenan in gel form must have a dehydrating compound. The common dehydrating agent is sugar. Sugar is a material that can attract water molecules that bind to carrageenan molecules, so that sugars can make a solid gel. The purpose of the study to determine the effect of additional sugar and carrageenan concentration on physical, chemical, and sensory characteristics of fruit leather of Ambon banana and to determine the amount of additional of sugar and carrageenan concentration according to sensory data to produce fruit leather with good sensory characteristics. This study used Completely Randomized Design (RAL) consisting of two factors and three replications. The first factor is the percentage of sugar consisting of 5%, 10%, and 15%. The second factor is the percentage of carrageenan consisting of 0.3%, 0.6%, and 0.9%. Tests carried out include physical characteristics (lighness, texture, tensile strength, and elongation), chemical characteristics (moisture content and ash content), as well as sensory characteristics (color, taste, aroma, texture and overall). The data obtained is processed using a fingerprint analysis analysis of variance using Minitab program V.1.7. If there is a significant difference or influence, then a tukey test on test level α ≤ 5% is used. The result of this research showed that the production of fruit leather of banana Ambon with the concentration of sugar and carrageenan added has a significantly characteristic sensory taste and texture, while no significant effect on the sensory characteristics of color, aroma, overall, physical characteristics (lightness, texture, elongation and tensile strength) and chemical characteristics (ash and water content). Determination of the best treatment in this study was found in A2B1 treatment using 10% sugar concentration and 0.3% carrageenan with a very liking assessment as follows 3% color; aroma 13%; 17% texture; 13% taste; and overall 13% with a total value of 59%. Keywords: caragenan, fruit leather, sugar

Abstract

The red dragon fruit peels (RDFP) have a high content of pectin and total phenolic compounds. This research studied the development of RDFP be an antioxidative edible film. The RDFP was extracted by microwave to obtain high pectin and polyphenol content, and then the red dragon fruit peel extract (RDFPE) was used as a based material. The RDFPE was added with 5% (w/v) of carboxymethyl cellulose (CMC) and 10% (w/v) of soy protein isolate (SPI) to increase their tensile strength. The result showed that RDFPE potential to develop as an antioxidative edible film. There are different effects of CMC and SPI. The addition of CMC had a positive effect on total polyphenol and antioxidant properties but SPI had a negative effect. Against the peroxide number of peanut oils, all RDFPE films can inhibit. The effect of CMC and SPI on physical and mechanical properties were increasing thickness, and tensile strength decreasing transparency, solubility, also elongation. The FTIR showed a difference in macromolecule interaction between RDFPE with CMC and SPI. The interaction between RDFPE with CMC occurred with pectin while SPI interacted both with pectin and polyphenol. Thus, macromolecule interaction affected on physical, mechanical, and antioxidative properties of RDFPE edible films, and revealed that CMC was more suitable to add to RDFPE edible film.
