This study investigated the effect of combining wheat flour and red bean flour on the chemical and sensory characteristics of pukis cake, aiming to identify the optimal concentration of red bean flour. A Randomized Complete Block Design (RCBD) with one factor and six treatment levels was applied. Sensory attributes evaluated included taste, aroma, color, texture, and overall acceptance, while chemical analyses measured moisture content, total dietary fiber, and anthocyanin levels. Data were analyzed using ANOVA, followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Results showed that red bean flour significantly influenced both chemical and sensory properties. Dietary fiber increased from 2.35% to 6.83%, and anthocyanin content rose from 2.06 mg/100g to 14.09 mg/100g. Moisture content showed no significant difference among treatments. Sensory qualities such as aroma, color, texture, and overall acceptance improved with higher concentrations of red bean flour, while taste remained favorable. Treatment P4 produced the best overall results, indicating it as the most optimal formulation. These findings demonstrate the potential of red bean flour as a functional ingredient in enhancing the nutritional and sensory value of traditional bakery products like pukis cake.

This study aims to determine the effect of tempeh substitution on the chemical, physical, and organoleptic quality of chicken nuggets. The design used was a Completely Randomized Design (CRD) with one factor, namely the tempeh:chicken ratio (0:250, 100:150, 150:100, 200:50, 250:0) and three replications. The parameters tested included water content, ash, protein, fat, crude fiber, texture (chewyness), and organoleptic tests (color, aroma, taste, texture, and overall preference) by 30 panelists. Data were analyzed using ANOVA and further Duncan's Multiple Range Test (DMRT) 5%.The results showed that increasing tempeh substitution decreased the water, ash, and protein content, but increased the fat and crude fiber content. The texture of the nuggets became less chewy, and the organoleptic scores for color, aroma, taste, texture, and liking also decreased. The product most preferred by panelists was a nugget with a composition of 150 g tempeh and 100 g chicken, with a liking score of 3.66. This product has a light golden yellow color (3.63), a distinctive aroma of chicken nuggets (3.63), a chicken nugget taste (3.56), and a slightly hard texture (3.43). The chemical and physical compositions were water content 48.85% (wb), ash 1.61% (db), protein 12.12% (db), fat 4.31% (db), crude fiber 7.37% (db), and elasticity 15.78 mm. This research shows that tempeh has the potential as a raw material for healthy nuggets and an alternative functional food.

Conventional mayonnaise is typically high in fat and cholesterol due to the use of oil and egg yolk as emulsifiers. This study aimed to develop a healthier alternative by formulating low-fat mayonnaise using soy protein isolate (SPI) as a plant-based emulsifier. The objective was to evaluate the physical and chemical properties of SPI-based mayonnaise selected through hedonic testing, and to compare it descriptively with a conventional sample (without SPI) and a commercial product. A Completely Randomized Design (CRD) was applied with five SPI concentrations: 0%, 1%, 2%, 3%, and 4%. Parameters observed included viscosity, texture, emulsion stability, color, pH, moisture, fat, and protein content. The 4% SPI formulation was identified as the most preferred based on sensory evaluation. Results showed that the 4% SPI sample had lower fat content (31.51%) and higher protein content (4.41%) than the reference samples. It also exhibited high viscosity (36,937.5 cP), good texture (0.094 N), excellent emulsion stability (96.80%), bright appearance (L=66.30; a=1.33; b=12.67), and a pH of 3.95. These findings suggest that SPI-based mayonnaise offers improved nutritional and physical qualities, making it a promising functional low-fat alternative favored by consumers.

Damage to fresh food such as fruits and vegetables due to exposure to air and humidity has become a common problem in the community. One innovative solution to maintain food quality is the use of starch-based edible films. This study aims to determine the effect of glycerol concentration on the physical and chemical characteristics of a starch-based edible film of purple sweet potato (Ipomoea batatas L.). The study was conducted using a Complete Random Design (RAL) with five treatments of glycerol concentrations of 6%, 8%, 10%, 12%, and 13% (v/b starch). The parameters tested include tensile strength, elongation, thickness, folding, moisture transmission rate (WVTR), and moisture content. The results showed that the increase in glycerol concentration had an effect on all the physical characteristics of edible films, except WVTR. Edible films with a glycerol concentration of 13% show the best characteristics with the highest elongation values (4.39%), highest folding (28 folds), thickness (0.07 mm), tensile strength (12.60 MPa), WVTR (0.02g/cm2.h) and moisture content (17.68%). Meanwhile, the best edible film chemical characteristics according to the 1995 SNI standard are at a glycerol concentration of 8% (15.77). Overall, all concentrations of purple sweet potato starch have met some of the standard parameters of commercial edible films. However, it still lags behind in terms of elongation, moisture content and tensile strength. However, this edible film has enough potential for use in small-scale or household packaging applications.

Edible film is a thin layer used to coat food or placed between food components, and it is consumable. This research aimed to assess the effect of adding teak leaf powder on the physical, chemical, and antibacterial properties of the edible film. The experiment was designed using a Completely Randomized Design (CRD), with teak leaf powder (J) as the independent variable. Four treatments were applied: J0 (0 g), J1 (0.25 g), J2 (0.50 g), and J3 (0.75 g) of teak leaf powder. Each formulation was tested for moisture content, thickness, tensile strength, elongation, water vapor transmission rate (WVTR), and antibacterial activity against environmental bacteria and Escherichia coli. The data obtained were analyzed using ANOVA followed by Tukey’s post hoc test at a significance level of α = 0.05. Physically, the addition of teak leaf powder increased the thickness of the edible film but decreased its tensile strength, elongation, and WVTR. The chemical parameter, moisture content, remained relatively stable across all treatments. In terms of antibacterial properties, the inhibition zone against environmental bacteria increased significantly. For Escherichia coli, no inhibition zone was observed in treatment J0, while treatments J1 to J3 demonstrated comparable antibacterial effectiveness.

Corn noodles are a gluten-free and high-fiber food product, but contain relatively low levels of β-carotene. To enhance their nutritional value and visual appeal, pumpkin puree (Cucurbita moschata Duchesne), known for its high β-carotene content and natural coloring properties, was added to the formulation. This study aimed to evaluate the effects of pumpkin puree addition on the physical, chemical, and organoleptic characteristics of wet corn noodles. A completely randomized design with one factor was used, comprising four treatment levels: 10%, 20%, 30%, and 40% pumpkin puree based on the total flour weight. The results showed that pumpkin puree significantly increased moisture contents and β-carotene levels (p<0.05), with the highest values found in formulation F4 (40%)—moisture contents of 65.40% and β-carotene of 287.07 µg/100 g (db). However, formulation F3 (30%) demonstrated the most balanced attributes, including bright colour (a = 4.41and b 22.77), optimal texture (cohesiveness 0.21 and adhesiveness 1.89), and the highest overall anelist preference score (overall score 3.0). Therefore, adding 30% pumpkin puree is the optimal formulation for producing wet corn noodles that are nutritious, visually appealing, and well accepted by consumers.
