Abstract

Water: bean ratio has an important role during extraction process in tofu industries. This factor determines yield and textural properties of tofu. The aim of the research was to evaluate the role of water: bean ratio on soymilk characteristics and to determine the extractability of solids, protein, and calcium. It was shown that the increase amount of water, from water to bean ratio of 10:1 to 30:1, reduced the total solids, protein and calcium content of soymilk, however, increased the total extracted solids, protein and calcium in the range of 53,53% - 68,44%,  73,08% - 83,21%, and 23,38% - 38,44%, respectively. Such an increase also resulted in the increase of 7S/11S globulin ratio, from 0,232 to 0,259.   Key words: soybean, water:bean ratio, globulin 7S/11S

Abstract

National rice production is currently quite a lot, but feared not enough for national rice necessity. Therefore, diversification of staple foods in the form of artificial rice is needed to support national food availability. Some problems in artificial rice product are first its texture. It tends to be hard due to the high content of amylose in Mocaf. As well the strong aroma of Mocaf makes artificial rice difficult to be accepted by consumers. Also we need to use additional materials such rice and porang flour to improve its texture and taste. This research used Randomized Block Design method (RBD) with two factors. The first factor was Mocaf and rice flour proportion consisting of 3 levels (90 : 10, 80 : 20 and 70 : 30) and the second factor was the addition of porang flour consisting of 3 levels (2%, 3% and 4%). The obtained data were analyzed using ANOVA (Analysis of Variance) and then continued using Least Significant Different Test (LSD) at α = 5%. The organoleptic test data were analyzed using Hedonic Scale Scoring Test and then continued using Duncan’s Multiple Range Test (DMRT) at α = 5%, while for determining the best treatment using De Garmo effectivity index method.The best treatment based on the physical, chemical and organoleptic parameters was obtained from the treatment Mocaf and rice flour proportion = 70 : 30 with the addition of porang flour 3% resulting artificial rice with the physical and chemical characteristics as follows color brightness (L *) 50.47, texture 1.27 N, rehydration capacity 177%, volume development 125%, water content 9.21%, starch 70.83%, amylose 18.86%, ash 0.62%, fat 2.71%, protein 2.71%, carbohydrates total 84.75%, oxalic acid 0.06% and organoleptic characteristics, as follows color 3.55 (neutral), aroma 3.60 (neutral), texture 4.00 (like) and taste 3.85 (neutral).Keywords: artificial rice, Mocaf, rice flour, porang flour

Abstract

The home industry for processing corn products into corn chips in Malang City includes  Sinar SME and Berkah SME. they both still do not have attractive, innovative and creative packaging designs. The packaging used has not been able to protect the product during the transportation process, and the design is less attractive. Corn chips produced by Sinar and Berkah SME’s did not have a variety flavors of products. This can have an impact on market saturation and reduce sales. There is still a lack of ability in both SME’s people in mastering technology and hygiene. Improvement efforts were made by improving the packaging design of Sinar and Berkah SME’s. The variety of corn chips that can be done to attract consumer appeal is to add a level of spiciness. Technology transfer is carried out in frying equipment and packaging activities using a pedal sealer machine.
