One type of food product that can incorporate mung bean flour is gyoza. Gyoza wrappers are typically made from wheat flour with low protein content. Mung bean flour can be added to improve its protein content. Additionally, mung bean flour in gyoza wrappers can be combined with fresh antioxidant-rich ingredients, such as Pak choy, to enhance antioxidant activity. This study aimed to determine the effect of using mung bean flour and wheat flour with the addition of Pak choy puree on chicken gyoza's sensory and chemical quality. The research employs a Completely Randomized Design (CRD) with a non-factorial approach, using four formulations: F0 (150 g wheat flour), F1 (100 g wheat flour and 50 g mung bean flour), F2 (75 g wheat flour and 75 g mung bean flour), and F3 (50 g wheat flour and 100 g mung bean flour). The obtained data were analyzed using ANOVA (analysis of variance) followed by the DMRT test at a 5% significance level. The results from the sensory evaluation indicate that the best formulation was the chicken gyoza sample with 50 g of mung bean flour and 100 g of wheat flour. The chemical analysis results for this formulation include moisture content (53.3%), protein content (11.23%), fat content (2.63%), and antioxidant activity (4.83%)
Sensory profile of five superior salak varieties in Indonesia: Profil sensori lima varietas salak unggul di Indonesia
No full textSalak (Salacca zalacca) is a tropical fruit widely consumed in Indonesia. The fruit has scaly skin resembling snake scales, often referred to as snake fruit. This study aimed to describe consumer preferences through the sensory characterization of five superior salak varieties: Madu, Pondoh, Gading, Gula Pasir, and Sidempuan, using the Rate-All-That-Apply (RATA) sensory method and a hedonic rating test. The results showed that salak Madu was characterized by sweet, salak ID (typical salak aroma), juiciness, and mealy attributes. Salak Pondoh was described as sweet, fruity, floral/perfumy, and cohesive of mass. Salak Gula Pasir had sensory attributes such as crispness, firmness, chemical, and grittiness. Meanwhile, salak Gading and Sidempuan shared similar sensory profiles, including green, starchy, peel-like, fermented, sour, bitter, and astringent attributes. Salak Madu received the highest preference level, presumably due to its dominant sweet taste. Conversely, salak Sidempuan and Gading showed lower acceptance levels because of their high sourness and astringency intensities. Overall, varieties with sweet taste profiles, such as Madu, Pondoh, and Gula Pasir, aligned better with panelists' preferences than those with dominant sour and astringent characteristics, such as Gading and Sidempuan. These findings have important implications for product development and marketing strategies, particularly in selecting salak varieties that meet consumer preferences for fresh consumption and differentiation in processed products

No full textOne way to extend shelf life and maintain the quality of fresh chicken meat is to implement an active packaging system. This research aimed to develop active packaging in the form of pads used in chicken meat with dual functions: Super Water Absorbent (SWA) as an adsorbent system and Ethanol Emitter (EE) as an antibacterial release system. The packaging in this study was first carried out by making SWA/EE with a ratio of 0, 4, and 2 (b/v). Furthermore, SWA/EE granules were inserted into non-woven PP bags to form an adsorbent active packaging pad. The experimental design used was a Randomized Group Design (RGD) with 2 factors, namely SWA/EE pad ratio 0, 4, and 2 (b/v) with non-pad as control and storage time (0, 1, 3, 5, and 7 days). Each treatment was repeated 3 times. The results showed that the SWA/EE ratio 4 (w/v) had better ethanol release and water absorption rate compared to other treatments. SWA/EE treatment with SWA/EE ratio of 4 (b/v) showed a significant difference on the anti-bacterial activity of S. aureus (34.58 mm) and total bacterial growth on storage days 3, 5, and 7, with the lowest value on day 3 (1.52 log CFU/g). SWA/EE treatment did not significantly different on the antibacterial activity of E. coli and total bacterial growth at day 1 storage. Packaging with an SWA-EE ratio of 4 (w/v) has the potential to be a double active packaging that can be used on fresh chicken meat

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.
