Abstract

Velva is a frozen food made from fruit puree, sugar, and stabilizers. Jicama contains a high fiber content, but the flavor is less preferred. Adding Sweet Orange juice can produce Velva high in fiber, vitamins, and flavors liked by the panelist. This study aimed to obtain the best ratio of velva from Jicama puree and Sweet Orange juice. The research used a complete randomized design (CRD) with five treatments and four repetitions to obtain 20 experimental units. The treatment in this study was the ratio of Jicama puree and Sweet Orange juice, namely BJ1 (70:30); BJ2 (60:40); BJ3 (50:50); BJ4 (40:60); and BJ5 (30:70). The data obtained were statistically analyzed using analysis of variance and continue with Duncan's multiple range test at the level of 5%. The results showed that the ratio of Jicama puree and Sweet Orange juice had a significant effect on crude fiber content, total dissolved solids, overrun, melting rate, vitamin C, and descriptive and hedonic sensory assessments such as color, aroma, taste, texture, and overall acceptance. The best ratio of velva was BJ4 with the ratio of Jicama puree and Sweet Orange juice (40:60). BJ4 treatment had crude fiber of 2.39%±0.25; total dissolved solids of 34.26%,±0.98; overrun of 8.88%±0.99; melting rate of 10.01 ml/min±0.60, and vitamin C of 34.32 mg±1.76. The BJ4 treatment had a yellow color, orange aroma, flavor, and soft texture.

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

The utilization of mung bean flour as a nutritional enhancer in food processing can serve as a preference for increasing protein content. 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%).

Abstract

Salak (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.

Abstract

Bananas is a tropical fruit that is quite popular because of their freshness and can be consumed directly or processed as a snack. Banana cultivation is increasing along with the increasing demand for bananas in the market. As a climacteric fruit, bananas ripen quickly so they spoil quickly and have a low shelf life. To extend shelf life, ethylene gas in the surrounding environment must be controlled, for example, using active packaging made from ethylene gas absorbent. Several studies used activated carbon from coconut shells, chitosan, and teak leaves as ethylene absorbent material to extend the shelf life of climacteric fruit (e.g., guava, avocado, and tomato) with various types of packaging and doses of absorbent materials. This study examines the shelf life of bananas packaged in active packaging that absorbs ethylene using activated charcoal from coconut shells. As a result, activated charcoal with the addition of KMnO4 to absorb ethylene could extend the shelf life of bananas for 6 days longer than without activated charcoal.

Abstract

The level of physiological maturity of the plant, productivity at harvest, and content in the material are all determined by harvest age, which is a component that is strongly tied to the phase of plant growth. Oyster mushrooms will undergo biochemical changes as they mature, but they will also change physically when they are harvested, especially in terms of color, texture, size, form, and the sections that may be eaten. This study aims to discover the optimal harvest age for yellow oyster mushrooms (Pleurotus citrinopileatus) based on their physical, chemical, and antioxidant activity. It also examines the impact of harvest age on the physical, chemical, and antioxidant activity of yellow oyster mushrooms (Pleurotus citrinopileatus). The design of this investigation was entirely random. This study used two harvest periods of yellow oyster mushrooms with harvest ages of 2, 3, 4, and 5 days after the appearance of pinheads as the treatment. Three times each experimental unit is repeated. The nursery, incubation, upkeep, and harvest of yellow oyster mushrooms comprised the study. The findings demonstrated that wet weight, rendemen, total phenol, and antioxidant activity of yellow oyster mushrooms were significantly influenced by harvest age. It is advised to harvest the yellow oyster mushroom on the third day after the appearance of pinheads.

Abstract

Fried sago crackers are dry local foods easily damaged by moisture during storage. To increase economic value and open commercialization opportunities, a study aimed to estimate the shelf life of white and red fried sago crackers using an acceleration method based on the water sorption isotherm curve. Estimating the shelf life was carried out by storing crackers in several modified jars containing different saturated salt solutions. Calculating the moisture permeability constant of polyethylene and polypropylene packaging was also carried out to support the necessary data. The results showed that sago crackers packaged in polypropylene had a longer shelf life than polyethylene plastic. The white sago crackers with polypropylene plastic had a shelf life of 19.89-69.83 days at 70-90% RH, while polyethylene was 12.02-42.21 days at 70-90% RH with 0.0434 g H2O.g solid-1 critical water content. The red sago crackers with polypropylene plastic had a shelf life of 18.26-69.93 days at 70-90% RH, while polyethylene was 11.04-42.27 days at 70-90% RH with a critical water content of 0.0455 g H2O.g solid-1. The chosen model for the water sorption isotherm curve was Hasley and GAB, with equation log (ln (1/aw)=-1.82-1.31 log Me for white sago fried crackers and Me=(0.5157aw)/(1-0.9632aw)(1+15.578aw) for red sago fried crackers, respectively. Fried sago crackers in polypropylene plastic packaging have the potential to be developed as local food products with a longer shelf life.

Abstract

Eucalyptus oil is an essential oil popular in Indonesia due to its ability to treat flatulence, induce a sense of warmth, and serve as an antibacterial, antiviral, antifungal, and aromatherapy agent. Melaleuca cajuputi is a species of eucalyptus plant that yields eucalyptus oil. This plant is commonly found in Central Maluku and West Nusa Tenggara. The distilling process of eucalyptus oil took four hours and involved using steam distillation. Several physical parameters, including cineole content, oil weight, specific gravity, optical rotation, and ethanol solubility, were utilized to evaluate the grade of the produced eucalyptus oil. The analysis of physical properties was conducted using SNI 06-3954-2006-compliant methodologies. The volatile compounds of eucalyptus oil were analyzed using the Gas Chromatography-Mass Spectrometry (GC-MS) technique. The test results indicated that the purity of eucalyptus oil from Maluku and NTB specifically met the requirements of SNI 06-3954-2006. GC-MS measurement revealed that eucalyptus oil from Maluku, with a yield of 1.42%, contained 26 chemical components, with 1.8-cineole comprising the highest percentage at 67.38%. In contrast, the yield of NTB eucalyptus oil was 1.84%, and it contained 21 volatile compounds of which the compound of 1.8 cineole made up 66.58% of the component composition
