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

Boba drinks are beverages served with chewy tapioca-based toppings known as “boba”, “bubble”, or “pearl”. These toppings are high in sugar, calories, and carbohydrates but have low amounts of fiber and vitamins. Adding carrot pulp to “Caboom” (Carrot Boba Milk) toppings is expected to increase fiber and vitamin content. However, there's an issue with texture; the boba toppings aren’t achieving the desired chewiness and tends to crumble easily. Therefore, the addition of another ingredient is necessary, and porang (Amorphophallus muelleri Blume) flour is a suitable choice because it’s known for its ability to act as a gelling agent due to its glucomannan content. This research aimed to determine how the ratio of porang flour and carrot pulp affects the characteristics of boba toppings and determine the right ratio for achieving the best boba toppings characteristic. In this research, a completely randomized design was used, involving six treatment levels representing different ratios of porang flour and carrot pulp: 0:100, 25:75, 50:50, 75:25, and 100:0, replicated three times, resulting in a total of 15 experimental units. The collected data underwent analysis through ANOVA and followed by Duncan Multiple Range Test (DMRT). The results revealed that the comparison of porang flour and carrot pulp had a significant effect (P<0,05) on water content, ?-carotene content, hardness, and the hedonic ratings for attributes such as color, aroma, taste, texture, and overall acceptance. Among the different ratios considered, the comparison of 50% porang flour and 50% carrot pulp emerged as the best boba toppings characteristic with water content 68,5%, ?-carotene content 0,94%, hardness 1,65 N, the color is slightly like, the aroma is slightly like, the taste is like, the texture is like, overall acceptance is like, the total dietary fiber content 5,51%, and antioxidant activity 9,62%.

Abstract

Chicken meatballs are commonly made of chicken meat and flour with various seasonings. This study aimed to determine the effect of heat-moisture treatment (HMT) modified canna starch addition on the characteristics of chicken meatballs and also to determine the right amount of heat-moisture treatment (HMT) modified starch addition to produce chicken meatballs with the best characteristics. A Completely Randomized Design (CRD) were used, with HMT addition treatment consisting of 6 types: P0: control (tapioca 25%), P1:5%, P2:10%, P3:15%, P4:20%, P5:25%. The treatment was repeated 3 times, so 15 experimental units were obtained. The obtained data were analyzed by analyzed of varian (ANOVA) on the SPSS program which was followed by Duncan’s Multiple Range Test (DMRT). The observed parameters in this study are water absorption content, elasticity level, water content, ash content, protein content, fat content, carbohydrate content, sensory test (hedonic and scoring), and resistant starch content. The result showed that the addition of HMT-modified canna starch had a significant effect on water absorption content, elasticity level, water content, protein content, fat content, carbohydrate content, color (hedonic and scoring), and resistant content. Chicken meatballs with the best characteristics were obtained from the addition of modified canna starch by heat moisture treatment (HMT) 25% with water absorption capacity of 33.82%, elasticity 7.57 N, moisture content 64.33%, ash content 0.79% , protein content 13.36%, fat content 5.24%, carbohydrate content 16.25%, and resistant starch content 3.00% as well as sensory assessment of color, namely dark ash and preferred, ordinary aroma, slightly chewy texture and preferred, ordinary taste and overall acceptance is preferred.

Abstract

Hot plate choice A is a type of main course produced by PT. Aerofood ACS Denpasar. The components of the Hot Plate Choice A menu are stored for 72 hours in a chiller at 5oC. Storage in cold (chilled) or frozen (frozen) conditions can affect the nutritional quality, decrease the quality, and sensory characteristics. This study aimed to determine the effect of storage time in the chiller on nutrients and sensory characteristics of the hot plate choice A menu and to determine the appropriate storage time for the hot plate choice A menu, which still has nutritional value and sensory characteristics suitable for consumption. The research method used a completely randomized design (CRD) with storage time treatments consisting of 8 levels, namely: (0 hours, 12 hours, 24 hours, 36 hours, 48 hours, 60 hours, 72 hours, and 84 hours). Each treatment was repeated 2 times to obtain 16 experimental units. The data obtained were analyzed using variance and if the treatment had a significant effect, then it was continued with the Duncan Multiple Range Test (DMRT). The results showed that storage time had a significant effect on moisture content, ash content, content fat, protein content, carbohydrate content, calorie content, and free fatty acid content Storage time in the chiller significantly affects moisture content, ash content, fat content, protein content, carbohydrate content, caloric value, and free fatty acid content, sensory preferences color, aroma, taste, texture, overall acceptability, colour, and textured scoring. The proper storage time to produce nutrients and sensory characteristics that are suitable for consumption in this study is at a storage time range of 0 hours to 24 hours with an average nutrient value at 24 hours storage, namely 56.069% water content, 1.101% ash content , protein content 38.999%, fat content 26.598%, free fatty acid content 0.020%, protein content 50.273%, caloric value 578.160 kcal, the color is liked slightly, color scoring with slightly, aroma is liked slightly, the texture is liked slightly, scoring texture with normal texture, the overall acceptance is liked slightly.
