The function of using a face mask is to remove dirt and dead skin cells found in the pores of the skin, open clogged pores and clean the remaining cosmetics that cannot remove with ordinary cleansers, repair and tighten the skin, provide nutrition, smooth, soften and maintain skin moisture. People are aware of halal-labeled cosmetics, one of which is face masks because some face masks contain gelatin. Some face masks on the market contain gelatin. Preparation of 5 reference samples with different concentrations. Preparation of face masks, DNA isolation, and checking the isolation results. The test results with the Nanodrop Spectrophotometer showed that the face mask DNA containing pig and cow gelatin extracted in this study ranged from 163.35 ng/µl in sample S6 to 83.550 ng/µl in sample S7. With the largest concentrations of 163.35 ng/µl and 83.550 ng/µl, while the highest purity value at the λ260/λ280 ratio was 1.41.

Encapsulated aromatic citronella extract (Cymbopogon nardus) and its responses to protein content, solubility, and water holding capacity of catfish bone powder

Wed, 21 Feb 2024 00:00:00 +0000

Aromatic citronella contains highly bioactive components that are easily degraded during processing and storage. Their stability decreases due to heat, light, and oxygen exposure. Encapsulation is one method to maintain the stability of bioactive components. This study aims to determine the content of protein, solubility, and water holding capacity (WHC) of aromatic citronella extracted and encapsulated by various maltodextrin concentrations and foam mat drying temperatures of catfish bone powder. The experimental design in this study used a completely randomized design (CRD) with two factors. Temperature variations in this study were 70°C and 80°C, and maltodextrin concentrations were 10% and 15%. Statistical analysis was performed with two-way ANOVA and continued with the DMRT (Duncan's Multiple Range Test) test at the significance level α = 5%. Total protein of encapsulated aromatic citronella extract on catfish bone powder ranged from 17.24-27.34%, solubility ranged from 34.53-55.64%, and WHC ranged from 4.49 – 43.03%. Maltodextrin concentration significantly affected protein content and WHC. Drying temperatures significantly affected the solubility of catfish bone powder with the addition of encapsulated aromatic citronella.

Ultraviolet (UV) A and Ultraviolet (UV) B rays can also hurt the skin, and sunscreen helps keep the skin awake. Wungu leaf has some potential for sunscreen because it has antioxidant activity that allows it to absorb UV light. Besides considering the security aspect, the formulation of the sunscreen spray also observes the halal critical points of the ingredients used. This study aims to formulate a more comprehensive sunscreen spray halal extract of wungu leaves with variations in the concentration of glycerin, a humectant. Data collection techniques run through descriptive analysis. This is made with variations in glycerin concentration: 5%, 10%, and 15%. The availability of formulated physical evaluations then included organoleptic tests, homogeneity tests, pH tests, viscosity tests, and test patterns of spraying. According to this study, availability in green, homogenous pH stands at 5.42 – 5.73, viscosity in the 1571 – 1983 cPs, and the targeting pattern at about 3 cm, 5 cm, 10 cm, and 15 cm at 5.67 – 16.6 cm. Therefore, in this study, the conclusion is that the availability of sunscreen spray with variations of glycerin has more physical properties that could be used. The more glycerin is used, the more available viscosity will increase.

Rosella flowers (Hibiscus sabrariffa L.) are plants that are useful as antioxidants. The content that acts as an antioxidant is a flavonoid compound. This study aimed to determine the effect of giving calliandra honey as a multiple active ingredient and single active ingredient (rosella petal extract, calliandra honey ) and ethyl vitamin C as an active ingredient. The lotion of ethanolic extract of rosela flower petals was made with three active ingredients: ethanolic extract of roselle flower petals with a concentration of 2.5%, calliandra honey 2.5%, and ethyl vitamin C 2%. Then, calliandra honey and ethanol extract of roselle flowers are combined with a concentration of extract 2.5% and calliandra honey (1.5%, 2%, and 2.5%). The physical and stability tests are the organoleptic, homogeneity, viscosity, dispersibility, pH, lotion stability, and the value of lotion's antioxidant activity. The activity test was carried out using the 2,2-Diphenyl-1-Picryhidrazil (DPPH) method, and the IC₅₀ of inhibition was calculated. The results of the study showed that all lotion formulations had antioxidant activity. The highest antioxidant activity was obtained in formula three, which had a value of 95.2 ppm (2.5: 2.5 %). Based on the Kruskal Wallis test, the asymp value was obtained. Sig. 0.000, which indicates that there is a significant difference in antioxidant activity. This is because the percent inhibition of each sample has a large enough difference.

Black soybean was fermented into Tempe to increase its functional properties and bioavailability. To develop black soybean tempe into a beverage for practical consumption, sappan wood and cinnamon were added to improve the appearance and functional properties. This research aims to determine the effect of sappan wood and cinnamon addition on antioxidant levels, phenolic levels, and brightness levels of black soybean tempe beverages. The research used a Completely Randomized Design (CRD) with a ratio of sappan wood and cinnamon at 0:0, 3:0.5, 2.5:1, and 2:1.5 (%w/w). Beverage made from commercial yellow soybean tempe was used as control. This research started by making tempe using Yogyakarta's traditional method. Beans were dehulled, boiled for 30 minutes, soaked in boiling water for 36 hours, boiled again for 30 minutes, inoculated with RAPRIMA, and incubated for 40 hours at room temperature. Tempe beverage was made by milling tempe and 80°C water at 1:3 (w/w) and the barks at the mentioned ratio, followed by filtration. The beverages were then analyzed for their Ascorbic Acid Equivalent Antioxidant Capacity (AEAC), total phenolics using the Folin-Ciocalteu method, and brightness levels using the CIE method. The results showed the antioxidant properties ranged between 82.67-86.93 mg AEAC/ml, total phenolics: 53.43-66.53 mg GAE/ml, color brightness parameter L*: 33.82-34.49, a *: 1.97-2.01, and b*: 4.09-5.05. It can be concluded that adding sappan wood and cinnamon improved the antioxidant levels and appearance of black soybean tempe beverages. The highest antioxidant properties and brightness level were obtained by adding 3% and 0.5% of sappan wood and cinnamon bark, respectively.

Turi leaf extract Ag nanoparticle liquid soap (Review of physical properties and antibacterial activity)

Wilda Amananti, Aldi Budi Riyanta — Wed, 21 Feb 2024 00:00:00 +0000

Research has been carried out on manufacturing liquid soap silver nanoparticles of Turi leaf extract. Ag nanoparticles have been used in various cosmetic and personal care products. This is because Ag nanoparticles have potential advantages such as increasing product stability, increasing absorption, and the ability to give special effects to the skin. From the physical properties test results, all soap formulas meet the standards set based on organoleptic, physical properties, pH, density, and viscosity. This research discusses the antibacterial activity of liquid soap. Formula 1 showed better antibacterial activity than formulas 2 and 3, with an inhibitory area reaching 23.84 mm. This can be explained by the fact that Formula 1 has a smaller particle size, namely 2161 nm. Formula 1 has the lowest AgNO₃concentration. The higher the concentration of AgNO₃ used in the synthesis, the greater the amount of Ag⁺ that must be reduced, resulting in greater agglomeration and a larger size distribution of Ag nanoparticles.
