Abstract

Functional compounds from black rice were extracted conventionally using organic solvents, namely ethanol-distilled water and ethanol-distilled water-acid (acetic acid and a mixture of lactic acid and acetic acid) along with distilled water as control. The effectiveness of each solvent was determined by analysis of functional compounds contents (anthocyanin content, flavonoids, total phenolic, and antioxidant activity), pH value, and the resulting color characteristics. The ethanol-distilled water-citric acid solvent produced significantly higher levels of anthocyanin, total phenolic, and antioxidant activity, with the lowest extraction pH, but produced fewer flavonoids. Red-purple black rice extract has the lowest brightness. The ethanol-distilled water-citric acid solvent has the best effectiveness in the extraction of black rice functional compounds.

Abstract

Indonesia is one of the cocoa producing countries in the world. Although the amount of cocoa production and planted area has increased, the quality of cocoa beans in Indonesia including Aceh is still low. This happened because the farmers did not carry out the fermentation process. Fermentation is one of the most important steps that must be taken to improve cocoa quality. However, it is rarely done because it takes a long time. The purpose of this study was to analyze the use of starter bacteria lactic acid (LAB) and acetic acid (BAA) indigenous Aceh cocoa in fermenting Aceh cocoa. The research was conducted by fermenting cocoa with two different factors, namely the type of starter (control, LAB, BAA, LAB-BAA mixture) and fermentation time (3,4 and 5 days). The results showed that the use of Acehnese cocoa indigenus bacteria starter and different fermentation time had an effect on fermentation conditions and the quality of fermented cocoa beans. Fermentation of cocoa beans with the addition of a dry starter affects the pH value and the percentage of fermented cocoa beans. The best treatment was obtained when using LAB starter with fermentation time of 4 days, with the same fermented quality of cocoa beans with fermentation using LAB and BAA for 5 days of fermentation. Further research is needed to confirm the quality of fermented cocoa beans produced by analyzing volatile chemical components and flavors.

Abstract

Basil leaf essential oil hard candy with the addition of cherry leaf extract is an innovation in the food sector in an effort to develop functional food products by adding antioxidant activity through natural ingredients that are easily found. Basil is a plant that is often used as a producer of essential oils. The addition of basil to dishes creates a distinctive aroma that enhances the taste buds and results in longer cooking. Cherry leaves contain various compounds such as flavonoids, tannins, triterpene, sanponins and polyphonols which have antioxidant activity.Flavonoids themselves also function as antihypertensive, antimicrobial, anti-inflammatory and can treat liver dysfunction. This study aims to determine the best formulation of hard candy basil essential oil with the addition of cherry leaf extract based on chemical, physical, and sensory analysis. The experimental design in this study was a completely randomized design (CRD).

Abstract

Dried cabya (Piper retrofractum Vahl.) is commonly used in making various types of herbs, spices, and cosmetic raw materials that require heating processes so that they require information on the value of thermal conductivity (k), thermal diffusivity (α), and specific heat (Cp). The thermal properties of dried cabya are affected by different phytochemical compositions at each maturity stage of the fruit. This study aims to determine and analyze the thermal properties and phytochemical content of dried cabya in three stages of green, orange and red maturity. Measurement of thermal diffusivity in this study uses the principle of onedimensional unsteady-state conduction heat flow using a vertical thermal diffusivity test. The value of thermal conductivity is determined indirectly by a calculation method based on the value of thermal diffusivity, specific heat, and density of the material. The thermal conductivity values of green, orange, and red paste cabya are 0.241 ± 0.016, 0.298 ± 0.005, and 0.344 ± 0.025 W/m°C. Reducing sugar levels in dried green, orange, and red cabya are 2.32 ± 0.16, 4.07 ± 0.13, and 6.44 ± 0.13 %, piperine levels are 2.42 ± 0.01, 1.97 ± 0.06, and 1.54 ± 0.05 %, and antioxidant levels are 87.15, 75.26, and 63.38 mg/mL. Based on the results of the study, red dried cabya have higher values of α, Cp, and k compared to orange and green because they contain higher levels of water and reducing sugars. However, red dried cabya have piperin and antioxidant levels which are getting lower
