Abstract

The major component of sweet potato flour is carbohydrate presented as starch. As other types of native starch that lack of physical and chemical characteristics, the sweet potato flour then is very limited in use. To improve the starch characteristics, it can be made by modifying the starch physically. This study was focused on modification of starch phisically by using autoclaving-cooling method with differ in steaming times (15 and 30 minutes) and drying methods (oven and sun drying). The results showed that the modified flour of sweet potato by autoclaving-cooling for one cycle has produce sweet potato flour with a granular structure that can expand and break, lower in starch content, higher in freezing and thawing stability, higher in water absorption index, and lower in hot and cooling viscosities

Abstract

Timphan is one of Acehness traditional cakes made from glutinous rice flour and wrapped in banana leaves.It has a short shelf life about 2-3 days. Instanisation of this product could extent the shelf life. This researchwas conducted to improvethe texture of instant timphan through liquid modification of timphan dough, levelof gelatinization and freezing treatments. The instant timphan was then examined by physical, chemical, andsensoryanalysis. The best treatment of instant timphan was found with combination between 1:1 ratio ofgrated coconut and water, 20 minutes steaming and be frozen and this instant timphanhas characteristics asfollows 27.5 minutes of cooking time, 4.33% of cooking loss, and 108.68 g/mm of hardness of timphantexture. According to proximate analysis, this product has 40.10% of water content,26.42% of starch content,3.68% of protein content, 2.87% of fat content, and 0.26% of ash content.Key words: Instant timphan, liquid modification, level of gelatinization, freezing treatment.

Abstract

The bioactive components of malacca (Emblica officinalis), which consist of phenolic, alkaloids, phytosterols, organic acids, and vitamins, are valuable for human health. The yield and quality of the bioactive components in the extract highly depend on the extraction technique, so it is essential to know the development of research on extraction techniques of the bioactive components of malacca fruit. In addition, the bioactive components in the extract have limitations in their application due to their stability, solubility, absorption, and bioavailability properties. Currently, nanoencapsulation technology has been applied to extracts of bioactive components to improve their properties. This review aims to provide comprehensive information about extraction techniques to obtain bioactive components of malacca fruit and presents the technique and purpose of the nanoencapsulation of malacca fruit extract. In addition to conventional techniques, several modern extraction techniques such as microwave-assisted extraction (MAE), ultrasound (UAE), pulsed electric field (PEF), and supercritical fluid (SFE) have been used to extract bioactive components of malacca fruit. Modern extraction techniques can produce extracts of bioactive components with higher yields than conventional techniques. The application of nanoencapsulation technology to malacca fruit extract consists of nanoliposomes and nanoparticles can increase permeability, antioxidant activity, antidiabetic and anti-inflammatory properties of malacca fruit extract.

Abstract

Tanaman tanjung (Mimusops elengi L.) merupakan tanaman pelindung yang banyak ditanam diperkarangan kantor, sekolah maupun dipingir-pinggir jalan dan hutan kota. Bagian tanaman tanjung yang biasa dimanfaatkan yaitu bunga, daun, akar dan kulit batang sedangkan buahnya tidak termanfaatkan sama sekali. Buah tanjung memiliki rasa sepat sehingga masyarakat tidak menyukainya. Rasa sepat pada buah bisa dikurangi dengan merendam buah dengan larutan kapur sirih. Salah satu cara yang dilakukan agar buah tanjung tidak terbuang yaitu dengan mengolahnya menjadi permen jelly. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman buah tanjung dengan larutan kapur dan konsentrasi gula terhadap karakteristik permen jelly yang dihasilkan. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK Faktorial) dengan 2 faktor. Faktor pertama yaitu lama perendaman buah tanjung dengan larutan kapur (J) dengan 3 taraf yaitu 12 jam (J1), 24 jam (J2) dan 36 jam (J3). Faktor kedua yaitu konsentrasi gula (G) dengan 3 taraf yaitu 70% (G1),  90% (G2) dan 110% (G3). Setiap perlakuan diulang sebanyak 3 kali ulangan sehingga diperoleh 27 satuan percobaan. Hasil penelitian lama perendaman buah tanjung berpengaruh sangat nyata terhadap rasa dan berpengaruh nyata terhadap tekstur permen jelly yang dihasilkan. Semakin lama perendaman buah tanjung maka rasa kelat pada buah tanjung akan semakin berkurang. Konsentrasi gula yang berpengaruh sangat nyata terhadap kadar air permen jelly buah tanjung. Semakin besar konsentrasi gula yang ditambahkan maka kadar air permen jelly yang dihasilkan semakin rendah. Interaksi lama perendaman buah tanjung dan konsentrasi gula berpengaruh nyata terhadap rasa permen jelly yang dihasilkan. Berdasarkan nilai organoleptik, buah tanjung yang direndam dengan larutan kapur sirih selama 24 jam dan konsentrasi gula 90% merupakan kombinasi perlakuan terbaik dalam pembuatan permen jelly buah tanjung, yang menghasilkan permen jelly dengan kadar air 10,58%, pH  4,42, organoleptik warna 3,63 (suka), aroma 3,77 (suka), rasa 4,33 (suka) dan tekstur 4,66 (sangat suka).Kata kunci: buah tanjung, konsentrasi gula, lama perendaman, larutan kapur, permen jelly
