Abstract

The purpose of this research was to know the effect of mulberry leaves powder addition on marshmallow characteristic and to determine the right amount of mulberry leaves powder addition that produced marshmallow with the best characteristics. This research used a completely randomized design with treatment consisting of 5 levels of concentration ratio of mulberry leaves powder (0%, 2%. 4%, 6%, 8%). Each treatment repeated 3 times in order to obtain 15 experimental units. The data obtained were analysed by analysis of variance and if there was an effect, then it will be followed by the Duncan Multiple Range Test (DMRT). The result showed that the addition of mulberry leaves powder had significant effect (p>0.05) on ash content, antioxidant activity, vitamin C, color intensity, color sensory, scent, texture, taste, and overall acceptance. The result showed that 4% concentration of mulberry leaves powder addition in marshmallow had significant effect on ash content, antioxidant activity, vitamin C, Color intensity, color sensory, scent, texture, taste, and overall acceptance. The 4% addition of mulberry leaves powder produced the best characteristics with 27.67% water content; 0.55% ash content; 15.82% antioxidant activity; 0.79 mg/g vitamin C; 46.30 L* score; -5.93 a* score; 20.77 b* score; color liked; scent liked; texture liked; taste liked; all acceptance liked.

Abstract

Tamarillo (Solanum betaceum Cav.) contain bioactive components such as anthocyanin. Anthocyanin in tamarillo act as a source of red pigment. This research aimed to determine the effect of pH on the anthocyanin stability of copigmented and encapsulated tamarillo powder and to determine the right pH to produce the best anthocyanin stability of copigmanted and encapsulated tamarillo powder. This research used a Complete Randomized Design with pH treatment consisted of five levels; pH 3, pH 4, pH 5, pH 6, pH7. Each treatment was repeated three times so obtain 18 experimental units. The data obtained were analyzed using analysis of variance and if the treatment had an significant effect on the test parameters, then continued with the Duncan Multiple Range Test (DMRT). The results showed that pH had a significant effect on anthocyanin color degradation, anthocyanin content, absorbance retention, L* values, a*, b*, hue and chroma. The best best treatment to maintain anthocyanin stability of copigmented and encapsulated tamarillo powder is pH 3 with the anthocyanin color with result degradation of 8.48%, anthocyanin content of 0.63 mg/g, absorbance retention of 96.51%, L* value of 40.03, value of a* 51.07, value of b* 56.30, hue of 47.79° and chroma of 76.01. Tamarillo powder copigmented and encapsulated can be used as a functional food ingredient in food products with an acidic pH.

Abstract

This study aims to identify the sensory profile of gayo aceh coffee quantitatively using the QDA method. The research phase began with panelist selection, which is followed by 15 people. The panelists who were selected and met the requirements were 10 people and proceeded to the next stage, namely FGD. The FGD stage aims to identify and determine the sensory attributes detected in coffee. Then proceed with sample preparation and testing, filling the test questionnaire and continued to the final stage of the research which is proceeding the data from the QDA analysis. The QDA result data is displayed in the form of spider web graphs and PCA biplot graphs. The results obtained 10 qualified and trained panelists who are baristas from Starbucks Tomang Raya and 13 sensory attributes identified in Gayo Aceh coffee consisting of floral aroma, fruity aroma, peanut aroma, chocolate aroma, spice aroma, bitter taste, sweet taste, sour taste, viscosity level, bitter aftertaste, dry aftertaste, astringent aftertaste and sour aftertaste. There are characteristic differences in each samples such as the "Hatana Coffee" brand sample which has dominant attribute of chocolate aroma and bitter aftertaste, the "Kafe.Inc" sample. which has the dominant attribute of sweet taste, the "Sentra Kopi" sample has the dominant attribute of peanut aroma, the "SOPIC" sample has the dominant attribute of floral aroma and bitter taste, the "Sunset Lotus" sample has the dominant attribute of fruity aroma, sour taste, and sour aftertaste, and the "Tageto Coffee" sample has the dominant attribute of spice aroma with high viscosity, dry and astringent aftertaste, while the coffee samples with the "Kieta Coffee" and "Sakha Coffee" brands tend to have chocolate and peanut aromas. This is because of the type of coffee used, the coffee roasting profile, or the post-harvest method of coffee.

Abstract

Flakes that are sold in Indonesia’s market are mostly made of wheat or cereal. Most of the nutritional content in flakes is carbohydrates, but people need complete nutrition for breakfast. Mocaf and peanut flour can be used to improve the nutritional value of flakes. This study aims to determine the physico-chemical and sensory properties of gluten free flakes made of mocaf and groundnut flour and also to obtain the right ratio of mocaf and peanut flour to produce flakes with the best physicochemical and sensory properties. The design used in this study was a completely randomized design (CRD) with a ratio of the amount of mocaf and groundnut flour (100%:0%, 90%:10%, 80%:20%, 70%:30%, and 60%:40%). All treatments were repeated three times to obtain 15 experimental units. The data obtained were analyzed by means of variance and if the treatment had a significant effect, continued with the Duncan Multiple Range Test. The results showed that the ratio of mocaf and groundnut flour had a significant effect on water content, ash content, protein content, fat content, carbohydrate content, crude fiber content, crunch time, scoring test on color, aroma, taste, hedonic test on color, aroma, texture, taste, and overall acceptance. A comparison of 70% mocaf and 30% groundnut flour produced flakes with the best physico-chemical and sensory properties with the criteria of water content 3.87%, ash content 1.65%, protein content 9.18%, fat content 24.00%, carbohydrate content 61.45%, crude fiber content 2.76%, crunch time 6.50 minutes, as well as sensory properties of light brown color and liked, peanuts flavored and liked, crunchy texture and liked, taste very liked and overall acceptance liked.
