Abstract

The process of decaffeination involves reducing the caffeine content in coffee and other substances containing caffeine using various methods, such as immersing them in siamese pumpkin extract. Siamese pumpkin extract contains protease enzymes that aid in the decaffeination process. This research aims to investigate the impact of soaking time with siamese pumpkin extract on decreasing the caffeine content of Kintamani arabica coffee beans and to determine the appropriate soaking duration for reducing the caffeine content of Kintamani arabica coffee. In this study, a Completely Randomized Design was employed with five levels of soaking time treatments, namely 0 hours, 12 hours, 24 hours, 36 hours, and 48 hours, which were repeated three times, resulting in 15 experimental units. The parameters observed included water content, protein content, caffeine content, and sensory evaluation, including aroma, taste, and overall acceptance. The data were analyzed using analysis of variance (ANOVA), and if there was a significant effect of the treatment, Duncan's multiple range test was applied. The duration of soaking Arabica Kintamani coffee beans with siamese pumpkin extract had a significant influence on the water content, protein content, caffeine content, and sensory attributes of the coffee. The optimal soaking time for producing decaffeinated coffee was found to be 24 hours, resulting in a caffeine content of 0.3% and a water content of 2.72%, with a protein content of 22.14%. The sensory evaluation revealed that the coffee had a light coffee aroma and a light bitter taste, which was preferred overall.

Abstract

Red curly chili (Capsicum annuum L.) is a commodity that has a high use value for the life of the Indonesian people, but is very susceptible to damage due to fracture while handled in the supply chain system. This is thought to be the main factor that causes a decrease in the shelf life of curly red chili. This study aims to determine the effect of the percentage of fractured chilies on the physical quality and respiration rate of curly red chilies, and also to determine the minimum percentage of fractured chilies that can affect the physical quality and respiration rate of curly red chilies during storage period. The experimental design used in this study was a completely randomized factorial design (CRD-factorial), with the first factor being the percentage of fractured chilies consisting of 0%, 4%, 8%, and 12%, and the second factor being the length of storage time consisting of 0, 2, 4, and 6 days. All treatments were repeated 2 times so that 32 experimental units were obtained. Data were analyzed by analysis of variance (ANOVA) and if the treatment had an effect on the parameters, it was continued with Duncan's Multiple Range Test (DMRT). Parameters observed were weight loss, moisture content, color, texture and respiration rate. The results showed that the interaction between the percentage treatment of fractured chili and storage time had a significant effect on weight loss and respiration rate, and had no significant effect on water content, color, and texture of curly red chili. The minimum percentage of fractured chilies that could have a significant effect on the physical quality and respiration rate of curly red chilies during the storage period was 4%, with a quality that is close to the control treatment until the 4th day of storage which are: 22.36% weight loss; 72.26% water content; 33.1 L* value; 48.3 a* value; 34.1 b* value; 34.08 N texture, and 17.46 mgCO2/kg.hour respiration rate. Keywords: curly red chili, physical quality, respiration rate

Abstract

Proso millet (Panicum miliaceum L.) was evaluated as a source of dietary fiber. Preprocessing of millet flour could increase dietary fiber. The dietary fiber is considered to provide benefits as a prebiotic. The purpose of this study was to analyze the effect of preprocessing on millet flour dietary fiber and its ability to stimulate the growth of probiotic Lactobacillus rhamnosus SKG34. The research was conducted in two stages, i.e. preprocessing millet flour and viability of probiotic bacteria (Lactobacillus rhamnosus SKG34) on different broth media. First, millet flour was made in various preprocessed method: without preprocessing, germination preprocessing, fermentation preprocessing, germination – fermentation preprocessing. Second, the viability of Lactobacillus rhamnosus SKG34 was carried out on various media broth: glucose-free MRS (control), MRS, adding dietary fibers extract from millet flour with different preprocessing. The results showed that millet flour with fermented preprocessing (F) provided the highest dietary fiber of 22.38% with a water content of 11.97% and a tannin content of 0.08%. L. rhamnosus SKG34 exhibited the highest viability when grown in MRS broth. The addition of dietary fiber extract did not significantly enhance the viability of L. rhamnosus SKG34 compared to the glucose-free MRS broth (control), which showed a viability of 5 log10 CFU/mL. Thus, it can be concluded that millet preprocessing with fermentation (F) can significantly increase the dietary fiber of millet flour. However, dietary fiber millet has no potential as a suitable prebiotic candidate for promoting probiotic bacterial growth.

Abstract

Fruit leather is a processed dried fruit in the form of thin sheets that can be rolled up. One of the fruits that can be processed into fruit leather is dutch eggplant. The elasticity of fruit leather is influenced by the binder used. The use of seaweed pulp binder in dutch eggplant fruit leather requires a long preparation time. One of the natural ingredients that has the potential to be used as a binder and is easy to prepare is chia seeds and agar-agar. The research was aimed to determine the effect of the concentration ratio of agar-agar powder and chia seeds on the physicochemical and sensory characteristics of dutch eggplant fruit leather and to determine the appropriate concentrations of agar-agar powder and chia seeds to produce dutch eggplant fruit leather with the best physicochemical and sensory characteristics. This study used a completely randomized design with a comparison of the concentrations of agar powder and chia seeds consisting of 6 levels: 100%:0%, 80%:20%, 60%:40%, 40%:60%, 20% :80%, and 0%:100% treatment was repeated 3 times. The data was analyzed with analysis of variance, and if the treatment had a significant effect, then followed by the Duncan's Multiple Range Test. The results showed that the concentration of agar-agar and chia seeds had a significant effect on tensile strength, L,a*,b* values, water content, crude fiber, flavonoids content, antioxidant activity, and sensory including hedonic tests (color, texture, overall acceptance). and scoring (texture). The best dutch eggplant fruit leather was treated with a ratio of agar- agar powder and chia seeds concentration of 40%:60% with a tensile strength value 2.18 MPa, L value 19.6, a* 15.36, b* 13.16, water content 13.55%, crude fiber 7.47%, flavonoids content 3.41mgQE/g, antioxidant activity 53.93%, color, taste, plastic texture and overall acceptance liked.

Abstract

Tamarillo (Solanum betaceum Cav.) is a tropical fruit that has the potential to be developed into functional food in the form of fruit juice containing probiotics. In order to develop the probiotic-containing product, the suitability of fruit juice to support the growth of probiotics and the viability of probiotics during the fermentation and storage processes are the prime concerns. Therefore, this study aims to determine the viability of the local probiotic Lacticaseibacillus rhamnosus SKG34 and the characteristics of fermented Tamarillo juice during storage at 4oC. Fermented tamarillo juice containing L. rhamnosus SKG34 is produced by fermenting Tamarillo juice with L. rhamnosus SKG34 and then stored at a temperature of ±4oC for 30 days. Population of L. rhamnosus SKG34, total sugar, total acid, pH, vitamin C, antioxidant capacity, and sensory characteristics were determined at 0, 5, 10, 15, 20, 25, and 30 days. The results showed that the probiotic L. rhamnosus SKG34 in fermented tamarillo juice was able to survive for 30 days with a population of 2.58 x 1010 CFU/ml from the initial population of 9.54 x 1010 CFU/ml. However, considering that chemical characteristics and other functional properties also influence the acceptability of fermented tamarillo juice, the optimal storage time is 20 days at 4oC. Under this condition, the fermented tamarillo juice containing 3.6 x 1010 CFU/ ml of L. rhamnosus SKG34; 11.23% sugars; total acid 0.98% acids; pH 3.44; 31.76 mg/100 ml vitamin C; and 4,725 GAEC/100 ml of antioxidant capacity, with favorable sensory levels.
