Abstract

Cassava noodles are noodles made from cassava and do not contain gluten (non gluten). Non-gluten-based noodles are less attractive to the public because of the physical properties of the noodles. The purpose of this study was to obtain the appropriate type of protein and the ratio of cassava flour to tapioca in the manufacture of cassava noodles. The method used is an experimental method which is divided into two stages. The first stage of the research was made treatment of soy protein isolate (ISP) 5%, ISP 10%, eggs 2.5%, 5%, and 7.5%. The second stage was treated with the ratio of cassava flour - tapioca ((80:20, 70:30, 60:40, 50:50) and the best types of protein were stage one (X), X-1.5%, and X + 1.5%. that the addition of 5% eggs can reduce the value of cooking losses, stickiness level, and increase the water absorption and the elasticity of the noodles The results of the sensory comparison test with commercial noodles show that cassava noodles are more chewy and stickier than commercial noodles but have no taste and aroma of cassava. In the comparison test between cassava noodles and commercial noodles, the value is acceptable. The results of the second stage of the study showed that the best noodles were the best cassava noodles from the treatment of the ratio of 60:40 cassava flour: tapioca and the addition of eggs of 6.5%. This treatment resulted in shrunken cassava noodles. lower cooking and stickiness, high water absorption, high elasticity, and sensoy hedonic grades are somewhat preferred.

Abstract

Cassava noodles are considered as a type of non-gluten-based noodles that have stickiness and higher cooking loss than wheat noodles. The addition of several types of hydrocolloids was allegedly able to improve the quality of starch-based analog noodles. The purpose of this study was to determine the characteristics of analogue noodles based on cassava plus carrageenan hydrocolloid compared to wheat noodles. The research method used was the experimental method of adding 0%, 5%, 10%, and 15% carrageenan to the cassava-based analog noodle formulation. The results showed that the addition of carrageenan to cassava-based analog noodles reduced the elasticity, chewability, water absorption and elongation of noodles, but increased the stickiness, tensile strength, and elasticity of analog noodles. Analog noodles whose characteristics of elasticity, stickiness, and hardness are close to that of commercial wheat noodles are those with 10% carrageenan added. The level of preference for cassava-based analog noodles added with 10% carrageenan was still below commercial wheat noodles which reached a hedonic level of moderate liking (score 5.0), however, the level of preference for analog noodles still reached neutral to moderate (4.5-5.0).BAHASA INDONESIA ABSTRAK: Mie singkong dianggap sebagai jenis mie berbasis non-gluten yang  memiliki sifat lengket dan susut masak lebih tinggi daripada mi terigu.

Abstract

Black tea has lower antioxidant activity than green tea, the color is slightly darker and less stable during storage. Therefore, it is necessary to add natural antioxidants so that antioxidants increase, and the color is brighter and stable. This study aims to determine the effect of adding lime juice and Eucalyptus globulus essential oil (MEEg) on antioxidant activity and color, as well as organoleptic hedonic brewing of black tea. The research method used was an experimental method consisting of 2 stages, namely the stage of determining the length of brewing black tea and the stage of adding lime juice (0, 1, 2, 3% v/v) and MEEg (0.00, 0.05, 0). ,10, and 0.15% v/v). The results showed that the best brewing time was 8 minutes with an IC50 value of 1411.24±75.79 ppm, a pH value of 5.25±0.02, a yellow-red color (oHue 75.93±3.16), and a lightness value. 47.09±1.06. The addition of lime juice tends to decrease antioxidant activity, total phenolic, total flavonoid, and total condensed tannins, but the addition of MEEg increases antioxidant activity, total phenolic, total flavonoid, and total condensed tannins in black tea. The addition of lime juice and MEEg increased the preference for the tea color and mint flavor, but decreased the preference for the sour taste and tea aroma. The selected treatment was the one with the highest antioxidant activity and hedonic value, namely the addition of 3.0% lime and 0.15% MEEg.Bahasa Indonesia Abstract:Teh hitam mempunyai aktivitas antioksidan lebih rendah daripada the hijau, warna seduhannya agak gelap dan kurang stabil selama penyimpanan.

Abstract

Ikan Sidat or eel fish (Anguilla bicolor) is a popular fish commodity in domestic trade as well as for export commodity. The use of marine yeast as fodder suffers from some weaknesses since it contains nucleic acids and rigid thick cell walls that obstruct the absorbance of nutrition. Optimizing the use of marine yeast as fodder ingredients can be done by fragmenting and reducing the yeast. This research attempts at optimizing the use of marine yeast regarding its rate of growth, fodder efficiency and the survival rate of eel fish. This research employs the complete random design using 4 different treatments and 3 repetition. In the four treatments, the fodder contained protein (45%) and iso energy (3.600 kkal.kg-1 fodder), which were applied to the treatment A 0% (control), B 5% (complete), C 5% (fragmented) and D 5% (reduced). The parameters used in this study were survival rate, specific growth rate, ratio of fodder conversion, ratio of protein efficiency, energy retention, protein retention and rate of metabolism. The data of this study showed the best result in the treatment D, 5% (reduced), showing survival rate value of 95.56%, specific growth at 1.12, food conversion ratio of 2.27, protein efficiency ratio of 0.98, protein retention at 18.26%, energy retention of 16.57, and protein metabolism rate at 81.96%. Keywords: eel fish, growth, marine yeast.
