Abstract

Making a drink mix fruit from the fruit of the banana ambon, california papaya, pumpkin and Solanum betaceum can be a way to enhance antioxidant content of their products, and will raise the value of fondness of the community towards it. This study aims to determine the right formula of the variation of composition fruit and temperature levels drying against anti oxidant and know received the community in power fruit drink mix. Methods used to making a drink mix fruit that is a method in which a Foam Mat Drying. Based on an analysis of the vitamin C the best conditions exist to variation composition fruit 50% of Solanum betaceum. While for antioxidant content IC50 the best conditions exist to variation composition fruit 50% of banana ambon at a temperature of 50 oC. The temperature drying affecting the womb IC50 antioxidant vitamin C and fruit resulting mix to the liqueurs. Based on the is the hedonic organoleptic, can was received by the fruit drink mix for its shade from variations composition 50% of pumpkin (50 oC), the scent of 50% of pumpkin (70 oC), and the sense of 25% respectively fruit (50 oC). So it can be concluded that variations composition fruit that is produced with composition of the 50% of pumpkin.

Abstract

Juwet fruit has a sour taste. The purple color of this ripe juwet comes from anthocyanins. Anthocyanins in fruit or vegetables can appear as red, purple, or blue, depending on the acidity (pH) conditions. Anthocyanins also act as a source of antioxidants. Antioxidants from anthocyanins are relatively safer than synthetic antioxidants that allow the promotion of carcinogenesis. Antioxidants will stimulate the body's system response to destroy free radicals. The magnitude of the benefits of antioxidants has encouraged many researchers to lift the natural potential with high antioxidant content to be processed into practical and easy dishes. Therefore, Juwet fruit processing is needed to increase public acceptance of Juwet fruit, one of which is by removing tannins from Juwet fruit by blanching and processing juwet fruit into instant powder that is practical and easy to consume. Both in the process of evaporation and drying. The purpose of this research is to increase the economic value of Juwet fruit as an instant powder drink which is rich in vitamins and high in antioxidants. Optimization of the process is carried out by combining the evaporation and drying processes to obtain products that comply with SNI standards. From the results of this study, the highest Vitamin C content was obtained at a drying temperature of 500C, which was 0.128%/1 g with an antioxidant reactivity of 50%.

Abstract

Celery (Apium Graveolens L.) is one type of herbal plant that is known to have many properties for human health. Despite its abundant availability, it has a relatively short shelf life, which is around 2-3 at room temperature. Celery can be used for the treatment of hypertension, rheumatism, gout, inflammation, appendicitis, typhoid, poisoning, insect bite wounds, cough, prostate, hair fertilizer, oily face, asthma and xerophthalmia. Given the many uses of celery leaves and the relatively short shelf life, this celery will be processed into a form of herbal drink that is ready for consumption. Therefore, this herbal tea will be a solution to extend the shelf life of celery leaves. In this study, celery will be dried using three different techniques: the sunlight method, an oven, and a dehydrator, which also serves as the study's variable. Sunlight drying takes 12 hours, 24 hours, and 48 hours, while oven drying takes 5 hours at 50oC and dehydrator drying takes 1 hour at 50oC. The 14 hours celery withering process is applied for all drying methods. The results of the study will be tested for water content, ash content, antioxidant activity test, flavanoid test and hedonic test. Only 2 methods were found to be in accordance with the INS, namely sun drying for 12 hours and using a dehydrator for 1 hour.
