Abstract

Generally, the type of orange used in marmalade production is Sunkist oranges.  In this study, Madu Susu Oranges (Citrus reticulata), a local orange variety typically consumed fresh and rarely processed into products, were used as the raw material for making marmalade. Additionally, sucrose is a key ingredient that can influence the balance between pectin and water in marmalade, affecting its characteristics and making it a valuable topic for further research. The main objective of this research was to determine the best sucrose concentration in the Madu Susu Orange marmalade formulation based on its physicochemical and organoleptic characteristics. The research design used was a Randomized Block Design, one factor of the sucrose concentration level (75%, 80%, 85%, 90%, and 95%) in 5 repetitions. The data were analyzed using ANOVA and further tested with the HSD test at a 5% significance level. The determination of the best treatment was conducted using the effectiveness index method. The results showed that the best treatment was at a 95% sucrose concentration with a 0.77 treatment value (TTV). The physicochemical and sensory characteristics of the Madu Susu Orange marmalade at 95% sucrose concentration were: total acidity of 0.52%, pH 5.82, total soluble solids of 68.00%, moisture content of 20.87%, and color values L* 29.94, a* 9.87, b* 49.90. Sensory test results for the best treatment were color 3.80 (liked), texture 3.67 (liked), and taste 4.17 (very liked).

Abstract

Ginger is known to contain various bioactive compounds, including phenolics (gingerol, shogaol, paradol). Several studies have shown that ginger extract is often added to ice puter to obtain healthier food product. Therefore, this study aims to analyze the result of adding ginger (Zingiber officinale Rosc.) extract with different concentration on antioxidant activity, total phenol content, overrun, hedonic test, and shelf life of ice puter. The study were conducted from November 2023 - February 2024 at Diponegoro University. The research design was a Completely Randomized Design (CRD) with 4 treatments and 5 replications, leading to a total of 20 experiment units. The experiment was conducted by adding ginger extract with different concentrations, namely P1 (0%), P2 (0.5%), P3 (1%), and P4 (1.5%). Shelf-life prediction was carried out with 3 replicates, leading to 9 experiment units for different storage temperatures (-5 °C, -18 °C, -22 °C). The sample selected from the hedonic test, P1 (0.5%) was evaluated for 28 days with changes in parameters of free fatty acid and emulsion stability. This result shows that the addition of ginger extract at various concentrations had significant effect on overrun, while, treatment P1 and P2 did not have significant effect on color and aroma. The addition of ginger extract increased antioxidant activity and total phenol content. In addition, the ice putter added with 0.5% ginger extract was the ice putter most preferred by panelists and had a shelf life of 210 days at -22°C, based on changes in free fatty acid during storage.

Abstract

Microencapsulation could be employed to coat bacteria with protective compounds to enhance their viability. The freeze-drying method uses low temperatures, thereby reducing heat damage. Bifidobacterium breve was used as a probiotic along with Streptococcus thermophilus and Lactobacillus bulgaricus, two common yogurt cultures. Yogurt, a nutrient-rich milk product, has the potential to be an effective probiotic carrier. This research aimed to examine how the freeze-drying process with varying ratios of coating materials affects the viability of the bacteria combination B. breve, S. thermophilus, and L. bulgaricus under acidic and bile salt conditions, as well as the microencapsulation efficiency and particle size. The treatments tested different ratios of whey protein isolate to trehalose as a coating (1:1, 1.5:1, 2:1, 2.5:1, 3:1). The 1:1 ratio yielded the best results, with lactic acid bacteria counts of 6.60 log colony/mL at pH 2.0, 6.84 log colony/mL at pH 3.0, 7.39 log colony/mL at pH 4.0, 7.47 log colony/mL at pH 5.0, 7.70 log colony/mL at pH 6.0, and 7.05 log colony/mL in a bile salt environment. This ratio demonstrated 107.96% microencapsulation efficiency and a particle size of 9.66 μm.

Abstract

The current development of marketing has been experiencing growth over time. Every activity carried out by marketing efforts results in impacts or risks. Assessing marketing activity risks allows marketers to control and monitor each risk and ultimately achieve their company's strategies. This research aimed to analyze the marketing risks of organic rice in Kediri Regency and formulate risk mitigation strategies for marketing organic rice in Kediri Regency. Expert respondents in this study were seven individuals selected through a census method who were organic rice marketers in the Kediri Regency. This study used nine marketing risk variables and 22 marketing risk indicators. The methods employed included Fuzzy Failure Mode Effect Analysis (FFMEA) and Analytical Hierarchy Process (AHP). FFMEA aimed to identify risks and provide risk assessments, while AHP aimed to determine alternative strategies for marketing risks. The results of the study showed that the highest priority risk levels and marketing risks included uncertainty in organic rice demand, price competition, limitations in sales areas, consumers' lack of familiarity with the target product, limited knowledge about sustainable technology, sorting practices that did not meet standards, packaging that affected product durability, minimal knowledge related to digital payments, and lack of partnership information. Nine strategies were proposed to minimize the existing risks, namely expanding digital marketing channels, offering product bundles, strengthening sales through cooperation with local stores, creating promotional media, conducting marketing management training, optimizing existing processes, improving packaging quality according to standards, financial planning related to business development, and improving information flow between partnerships.

Abstract

Hyperglycemia is characterized by elevated blood glucose levels, defined as instant blood glucose exceeding 200 mg/dL or fasting blood glucose surpassing 126 mg/dL. This condition has the potential to increase free radicals in the body. Using herbal ingredients or herbal drinks can also be a way to control blood glucose and free radicals. The Uncaria genus has functional anti-diabetic properties because it contains alkaloids and flavonoid compounds with antihyperglycemic and antioxidant effects. This study aimed to measure the antioxidant and antihyperglycemic potential of bajakah herbal tea with its raw materials (bajakah wood extract, honey, and Amblycarpa lime (jeruk Sambal)). The formulation of Bajakah herbal tea consists of 19.32 g Amblycarpa lime (jeruk Sambal), 46.38 g Bajakah rod extract, and 57.97 g honey. Antioxidant activity was achieved using the 2,2-diphenyl-1-picrylhydrazyl or DPPH method, and antihyperglycemic methods were used, such as the Oral Glucose Tolerance Test (OGTT). Physical characteristics are also tested for pH, color, and total dissolved solids. Data was analyzed using one-way ANOVA. The results showed that the combination of Bajakah-based herbal drinks, Bajakah herbal tea (123.67 g or equivalent to a carbohydrate content of 50 g), and the single preparation did not have antihyperglycemic activity. However, bajakah herbal tea has the highest antioxidant activity compared to its raw materials.

Abstract

Avocado is a climacteric fruit that experiences a surge in respiration and ethylene production after harvest, which accelerates its deterioration. One method to extend its shelf-life post-harvest is using edible coatings. This study evaluated the effects of various concentrations of edible coatings made from porang tuber starch and ginger extract on avocado quality during storage. A two-factor experiment was arranged in a randomized block design with 3 replications.  The two factors studied were the concentrations of porang starch (0%, 1.5%, 2%, and 2.5%) and the concentrations of ginger extract (0%, 4%, 6%, and 8%). Observed parameters included weight loss, total soluble solids, firmness, damage percentage, and sensory color, texture, and taste evaluations. Storage was conducted at room temperature (27±2°C) for 10 days. The research results indicated that the quality of avocados was significantly affected by the single treatment using edible coatings made from porang starch or ginger extract, while the interaction between the two only had a significant effect on weight loss. The use of 2% porang starch or 6% ginger extract was able to reduce weight loss by up to 13.73%, maintain fruit firmness at 7.71±1.383 kgf.cm⁻², total soluble solids at 1.25±0.127 °Brix, and resulted in sensory scores of color 1.67±0.608 (purple), texture 1.58±0.568 (soft), and taste 2.25±0.688 (slightly liked). The damage rate of the avocados reached 47.21±16.665%. Thus, this combination of edible coating proved effective in maintaining the physical, chemical, and sensory quality of avocados during storage.

Abstract

Annatto is a natural pigment that is a common ingredient in the food industry. Conventionally, extraction is performed using oil or organic solvents. This study aims to analyze the color characteristics of annatto produced using a combined maceration method and microwave-assisted extraction (MAE) using aquadest as a solvent. The pH of the aquadest was adjusted using citric acid and Ca(OH)2 to produce pH 4, 7, and 9.  The control used only maceration with distilled water without pH adjustment. Annatto extraction began with maceration using a magnetic stirrer at a temperature of 80oC for 5 minutes. Further, the MAE method used 100 W of power for 2, 4, and 6 minutes. Bixin and norbixin were analyzed to determine the pigment. Color was measured using a colorimeter to assess L (brightness), a (redness), and b (yellowness), and the maximum wavelength was determined. The results showed that extraction using the maceration or a combination of maceration and MAE produced 1.5% pigment. Higher brightness was made by the combined method using pH 4 aquadest for 2 minutes. A higher intensity of red color was created by the combined method with pH 9 aquadest for 4 minutes, while there was no difference in the intensity of yellow color between maceration and the combined method. Aquadest as a solvent is effective for annatto extraction by maceration and a combination of maceration and MAE. The annatto extract has a maximum wavelength of 300 nm.
