Abstract

Bottled drinking water is one of the beverage industries that dominate the soft drink market in Indonesia. An isotonic drink is bottled drinking water with an osmolality content similar to body fluids to replace lost body fluids after activities. This research aimed to develop and innovate isotonic drinks, based on local commodities such as butterfly pea and cinnamon with good quality and unique characteristics, so that can increase consumer interest in isotonic drinks. This study used a non-factorial Completely Randomized Design (CRD) method consisting of 6 levels (ratio of butterfly pea extract and cinnamon extract) i.e., P1 (80%:20%), P2 (70%:30%), P3 (60%:40%), P4 (50%:50%), P5 (100%:0%), dan P6 (0%:100%). The analysis includes viscosity, color index, and sensory analysis (color, taste, viscosity, and general acceptance). The results showed that the comparison formulation of butterfly pea extract and cinnamon extract had a very significant effect (P<0,01) on the physical and sensory characteristics of isotonic drinks. The value of the color index (˚Hue) range of 298.8–307.0, viscosity value range of 4.78–6.88%, and hedonic organoleptic, i.e. color range of 4.990–6.434, aroma range of 4.568–6.242, taste range of 4.550–6.360, the hedonic value of viscosity range of 4.910–5.876, and general acceptance range of 4.942–6.240. The best results of the isotonic drink was P1 (ratio of butterfly pea extract and cinnamon extract of 80%:20%) which produced the highest hedonic value and the physical characteristics. So, the butterfly pea and cinnamon extract can be made as a combination of an isotonic drink innovation. Keywords: butterfly pea extract, cinnamon extract, isotonic drink

Abstract

This study aims to determine the effect of sugar dosage and fermentation time on the quality of sauerkraut as a source of probiotics. This study used an experimental method in a 3x3 factorial completely randomized design (CRD). The first factor is three treatments of sugar concentration (A), namely A1 (2%), A2 (3.5%), and A3 (5%). The second factor is three treatments of fermentation time (B), namely B1 (5 days), B2 (7 days), and B3 (9 days). The results showed that there was no interaction (P>0.05) between factor A and factor B in the water content, but the water content had a significant effect (P<0.05) separately in factor A and factor B. In total LAB, there was a very significant interaction (P<0.01) between factor A and factor B, and in factor A and factor B. In pH, there was a significant interaction (P<0.05) between factor A and factor B, but a very significant effect (P<0.01) in factor A and factor B. In acid content there was a significant interaction (P<0.05) between factor A and Factor B, but a very significant effect (P<0.01) on factor A and factor B. This study concludes that cabbage processed into sauerkraut can be used as a probiotic supplement. The addition of 3.5% sugar and 7-day fermentation resulted in 91.11% water content, 3.43 pH, 2.93% total acid, and 7.4 x 109 total LAB

Abstract

Ketepeng cina leaf herbal tea is a functional beverage made from the dried leaves of Cassia alata (ketepeng cina), which are known to contain beneficial bioactive compounds. However, its use as a herbal drink remains limited. This study aimed to investigate the effects of stevia leaf addition (0%, 6%, 12%, and 18%) and brewing time (2, 3, and 4 minutes) on the physicochemical and sensory characteristics of ketepeng cina leaf herbal tea. A completely randomized design (CRD) with a two-factor factorial pattern and three replications was employed. The parameters evaluated included color index, pH, total soluble solids (TSS), total flavonoids, total phenols, antioxidant activity, and sensory attributes. Data were analyzed using ANOVA at a 5% significance level, followed by Duncan’s Multiple Range Test (DMRT) when significant differences were found. The findings showed that stevia concentration and brewing time significantly influenced the tea's characteristics. The optimal formulation was achieved with an 18% stevia concentration and a 3-minute brewing time, resulting in 3.68°Brix TSS, 0.18 mgQE/g total flavonoids, 1.93 mgGAE/g total phenols, and 49.21% antioxidant activity. This study suggests that the addition of stevia and controlled brewing time can improve the functional and sensory quality of ketepeng cina herbal tea, making it a promising alternative in the development of antioxidant-rich herbal beverages.

Abstract

North Sumatra is the largest producer of incense (benzoin) in Indonesia and the world. There are 3 varieties of incense that have the potential to be developed. Indonesia has exported incense to Singapore, Malaysia, and China. Incense is exported in the form of raw materials, so the added value is minimal. In order to increase the added value of incense, it can be produced into incense extract. So far, extraction methods have been carried out using conventional methods, including maceration, boiling with water, and distillation with water vapor. The potential of incense has not been fully utilized, especially from its extraction method, so it still needs to be developed. This article aims to review and identify the chemical components of frankincense (Styrax benzoin) and its extraction methods. In addition, the prospects for product development from frankincense are also discussed. Incense extraction with Ultrasonification Assistant Extraction (UAE) is expected to increase the efficiency of the extraction process. The use of solvents and low temperatures, as well as a short extraction time, can maintain the quality of the incense extract. Incense extract can be applied as raw material for perfumes, pharmaceuticals, medicines, and nano applications such as anticancer and antibiofilm. The incense consists of some active ingredients such as cinnamic acid, benzoic acid esters (such as coniferyl cinnamate and cinnamyl), pinoresinol, -caumary benzoate, benzoic acid esters, and triterpenes. These active ingredients are applied as antibacterial and antioxidants. This literature review provides an overview of the characteristics of active ingredients in incense to expand its applications. Incense extract can be applied as a food additive, pharmaceutical, and health ingredient.

Abstract

Andaliman is an endemic flora in the region around Lake Toba and is commonly used as a spice by the Batak ethnic community. Andaliman fruit in extract form has a lot of potential as an antimicrobial, anti-inflammatory and antioxidant. All the benefits possessed by andaliman extract have the potential to be widely used by the community. Therefore, it is important to know the shelf-life of the extract and the most suitable type of packaging to extend its shelf-life. This study aims to estimate the shelf-life of andaliman fruit extract and the packaging that can extend the shelf-life of the extract. The estimated shelf-life was calculated using the accelerated shelf-life test (ASLT) method using Arrhenius approach with the parameter of total flavonoids. This study used two types of packaging, namely glass bottle and plastic bottle stored at 37, 45, and 55 °C for 1 month with weekly testing. The results showed that andaliman fruit extract in plastic bottle packaging can last for 7.8 months at 37 °C and 6.8 months at 55 °C. While stored in glass bottle, andaliman fruit extract can last up to 12.4 months at 37 °C and 10.5 months at 55 °C. Based on these data, it is known that the shelf-life of extracts is influenced by storage temperature and packaging.  The higher the temperature, the shorter the shelf-life and the smaller the permeability, the longer the shelf-life.
