POTENTIAL ESSENTIAL OILS FROM GREEN BETEL LEAF (PIPER BETLE L.) AS A NATURAL
PRESERVATIVE FOR MEAT FOOD

sesquiterpene. Betel leaves also contain secondary metabolites such as organic acids, amino
acids, sugars, vitamins, tannins, fats, starches, and carbohydrates that affect the quality
(Handoyo, 2020).
Betel leaves (Piper betle L.) belong to the Piperaceae family and the genus Piper (Sarjani
et al., 2017). Betel leaves contain 4.2% essential oils, which mostly consist of active compounds
such as eugenol, cineol, and cavicol, which have antibacterial properties. These compounds
are effective in inhibiting the growth of food spoilage bacteria, making betel leaves a natural
preservative that can slow or delay spoilage in food products (Andayani et al., 2014). Green
betel leaves contain phytochemical compounds such as tannins, saponins, flavonoids,
alkaloids, terpenoids, steroids, and phenolics, which function as antimicrobials and
antioxidants. Green betel leaf essential oil contains 4.2% essential oils, mainly eugenol, cineol,
cavicol, and other compounds. The phenol and phenylpropanoid content in this essential oil
has strong antibacterial and fungicidal properties ( Nisyak & Haqqo, 2022).
Research by Mentari et al. (2016) showed that betel leaf extract (Piper betle L) contains
active compounds such as essential oils, tannins, flavonoids, and riboflavin, which have
antifungal, antimicrobial, and antioxidant properties, effectively preventing the growth of
spoilage bacteria in food. Betel leaves used for essential oil isolation come from the middle to
the base of the stem, using a steam-water distillation technique to produce optimal essential
oils without compound damage (Christiani et al., 2023).
Essential oils generally contain two groups of chemical components: Hydrocarbons and
oxygenated hydrocarbons. In citronella oil, the main compounds, such as citronella,
citronellol, and geraniol, have high economic value that can be increased through the
manufacture of derivative compounds and standardization (Murni & Rustin, 2020).
Natural preservatives produced from natural ingredients are safe preservatives for
preserving tofu. Natural ingredients that have the potential to be used as natural preservatives
are betel leaf extract (Piper betle) and noni fruit (Morinda citrifolia), because they have
antibacterial properties. Betel leaves (Piper betle L.) have health benefits such as treating
wounds, toothache, and vaginal discharge. Noni fruit (Morinda citrifolia), in addition to being
consumed, can be used for health, such as lowering high blood pressure, diabetes, and
rheumatism (Pakpahan et al., 2015)
Food preservatives can be synthetic and natural preservatives (antimicrobials). The
concentration of preservatives permitted by food regulations inhibits rather than kills
contaminating organisms. According to the Regulation of the Minister of Health of the
Republic of Indonesia Number 1168/MENKES/PER/X of 1999, there is a prohibition on the
use of formalin as a food additive. Formalin is a toxic chemical that, when swallowed, will
cause stomach irritation, nausea and vomiting, nerve and kidney damage, and even death
(Kayaputri et al., 2017).
Food comes from plants and livestock, with livestock products being the main source of
nutrients. Meat, which is rich in nutrients, is susceptible to contamination by microorganisms
due to its high water activity (Aw) content. Preservatives such as sodium benzoate are needed
to prevent contamination, but some producers in Indonesia still use prohibited preservatives
such as borax in processed meat products (Dwiningrum et al., 2023).
The study of the potential of betel leaf extract (Piper betle L.) as a natural preservative
for selar fish (Selaroides leptolepis) showed a significant effect on the concentration of 30%,
with a Fcal value of 3.14 and an F Table of 2.85 at α = 0.05. 30% betel leaf extract effectively
preserves selar fish in 32 hours. The hedonic test on fried selar fish also showed a significant
effect on taste, aroma, color, and texture , so that hypothesis was accepted .
The study used a completely randomized design (CRD) using 5 treatments and 4
replications, namely T0 (unmarinated beef) and T1–T4 (soaked in garlic juice for 5, 10, 15, and
20 minutes at room temperature 25°C). As a result, marinating beef in garlic juice can reduce
water content and total E. bacteria, but does not affect the pH value after 8 hours of storage at
room temperature.
The administration of betel leaf extract at different levels had no significant effect
(P>0.05) on the pH value of broiler chickens. The lowest pH value was found in P3 (6.18),
which was lower than P0 (control). Although betel leaf extract is acidic because it contains
