Abstract

Teak (Tectona grandis) leaves is commonly used as the packaging material of traditional food in Indonesia. This study aimed to determine the physical and chemical characteristics of teak leaves with various maturation stages to obtain information about the potency of teak leaves as active packaging material. The physical characteristics analysis including leaf color, thickness, and tensile strength, while chemical characteristics were moisture, fat content, fatty acid, and volatile profile. The results showed that the color, thickness, tensile strength, moisture, and fat content, were light green, 0.306±0.024 mm, 0.22±0.114 MPa, 74.93%, and 2.52% respectively for young teak leaves; while the mature has darker green, 0.388±0.001  mm, 0.36±0.163 MPa, 73.05%, and 2.54% respectively. The fatty acid profiles showed that young teak leaves contained 5 types of fatty acids, dominated by lignoceric acid; while mature teak leaves contained 9 types of fatty acids dominated by tricosanoic acid. The volatile components of young teak leaves e.g. acid and ester compounds, while the mature was dominated by acid and ether compounds. From the results, it is suggested that the use of teak leaves as active food packaging material can be scientifically justified.

Abstract

Incorporating ginger into gelato can significantly enhance its physical properties and sensory attributes. Ginger contains bioactive compounds like gingerol, which contribute to its distinctive flavor and health benefits, such as anti-inflammatory and antioxidant properties. Ginger can contribute to a smoother texture by interacting with the fat and protein structures in the gelato as well as can enhance the melting resistance of gelato, making it more stable and enjoyable to consume over a longer period. The addition of ginger provides a refreshing, spicy flavor that can elevate the overall taste profile of gelato. This study analyzed the impact of adding ginger extract at different concentrations on the overrun value, melting resistance, viscosity, and hedonic properties of gelato. A completely randomized design was used, with treatments including 0% (T0), 0.5% (T1), 1% (T2), and 1.5% (T3) ginger extract. Higher concentrations of ginger extract affected all parameters: overrun values ranged from 15.72% to 22.03%, melting resistance from 36.64 to 42.06 minutes, and viscosity from 10.06 to 12.76 dPas. Hedonic testing revealed that panelists preferred gelato with 0.5% ginger extract (T1). In conclusion, adding ginger extract to gelato significantly affects its overrun value, melting resistance, and viscosity, with the 0.5% concentration being most preferred by consumers.

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 increasing global demand for meat products illustrates the importance of safe and effective preservation methods. Butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tertiary butylhydroquinone (TBHQ) are common synthetic preservatives that stop microbial growth and lipid oxidation. However, they have been linked to negative health effects. Consequently, natural alternatives such as essential oils (EOs) have gained attention due to their antimicrobial and antioxidant activities. Mechanistically, EOs disrupt microbial cell membranes, inhibit key metabolic enzymes, and scavenge free radicals that initiate lipid oxidation. This review discusses the mechanisms and applications of various essential oils as natural preservatives in meat and meat products. Essential oils, which are high in phenolic compounds, work by breaking down microbial cell membranes, stopping enzymatic systems, and neutralizing free radicals that cause oxidation. Several studies have demonstrated that essential oils (EOs) function as a promising natural preservative in meat products by utilizing specific mechanisms to enhance chemical, microbiological, and sensory quality. For instance, rosemary essential oil (REO), when integrated into vacuum packaging, effectively extends the shelf life of chicken meatballs by inhibiting microbial growth and scavenging free radicals to prevent lipid oxidation. Similarly, oregano essential oil (OEO) exhibits strong antimicrobial action against foodborne pathogens like Salmonella enteritidis and Escherichia coli in dried meat while enhancing sensory properties. In sausage products, nutmeg essential oil (NO) demonstrates its antioxidant capacity by significantly reducing lipid oxidation indicators such as thiobarbituric acid reactive substances (TBARS), suppressed mesophilic bacteria growth, and improved aroma stability during storage. Collectively, these findings confirm that essential oils represent promising natural preservatives that offer a safer multi-target alternative to synthetic additives, especially in the mechanism of cell membrane damage and lipid peroxidation inhibition.
