Abstract

Black rice is one of the local varieties that has the best pigments, especially anthocyanins, compared to white rice and other rice. One of the uses of black rice as a functional food is the manufacture of ready-to-drink instant drinks that can maintain product quality and do not have added preservatives. The purpose of this study was to determine the physicochemical characteristics including anthocyanin levels, antioxidant activity, color intensity, and sensors with the addition of maltodextrin concentration..The research procedure was carried out first, black rice extraction, making black rice extract instant drink, and black rice extract instant drink formulation. The results showed that increasing the concentration of maltodextrin had a significant effect on physicochemical characteristics (anthocyanin levels, antioxidant activity, color intensity) and sensory (color and taste), but had no significant effect on sensory (aroma). The best treatment for an instant drinks with black rice extract is based on physicochemical tests, namely anthocyanin content (15.40mg/g), antioxidant activity (58.14%RSA), color intensity °Hue (41.02) Red and sensor test has a score of (3.45) close to like , contained in the addition of 30% maltodextrin concentration.

Abstract

Galangal (Alpinia galanga) is a type of spice that is widely used as a spice and medicine. Galangal bioactive components such as flavonoids, terpenoids and phenolics have the potential to be antibacterial. Today has been widely studied the potential of galangal as an alternative preservative for natural food and fresh fish has characteristics that are prone to damage, especially microbiological damage, this is influenced by the characteristics of fresh fish with high water content, neutral pH and soft texture, microorganisms that destroy fresh fish include: Bacillus alvei, Pesudomonas aerogenosa, and Staphylococcus saprophyticus. Flavonoids, terpenoids and phenolics and other bioactiv components in galangal are able to inhibit bacterial growth in fish through mechanisms such as damaging bacterial cell walls, disrupting cell osmosis pressure and cell wall formation. Literature search both from research journal, theses and books. This review will be discussed the ability of galangal to inhibit microorganisms that destroy fresh fish and future research opportunities for formulations of natural ingredients as preservatives. Galangal has the potential as a preservative for fish trough the mechanism of inhibiting the growth of destructive microorganisms.
