Description:

Penggunaan bahan kimia sintetis pada pembuatan effervescent menyebabkan kekhawatiran pemerintah akan pengaruhnya terhadap kesehatan, sehingga diperlukan bahan-bahan alami seperti jahe, sereh, dan pemanis alami sebagai pengganti bahan kimia sintetis yang sudah ada. Prosedur pembuatan effervescent dari ekstrak jahe dan sereh yang pertama yaitu menimbang sereh sebanyak 167 gr, mengupas dan memotong sereh, merebus sereh dengan penambahan air sebanyak 2 l hingga mendidih, lalu menyaringnya. Tahap kedua yaitu membuat ekstrak jahe dengan menimbang jahe sebanyak 1000 gr, mengupas dan mencuci jahe, menghancurkan jahe dengan menambahkan ekstrak sereh, menyaringnya, lalu memanaskan ekstrak jahe dan sereh yang didapat pada suhu 100oC. Tahap ketiga yaitu memanaskan ekstrak jahe dan sereh dengan pemanis alami sesuai dengan variabel jenis pemanis yaitu gula pasir, glukosa, dan gula merah sebanyak 1765,1 gr sambil diaduk-aduk hingga menjadi karamel. Variabel yang digunakan adalah jenis bahan pemanis alami yaitu gula pasir, glukosa, dan gula merah. Tahap keempat yaitu mengeringkan karamel hingga menjadi serbuk, menghancurkan serbuk, memanaskannya pada suhu 50oC, lalu menghaluskan serbuk yang didapat dengan ayakan 100 mesh. Tahap kelima yaitu mencampur bubuk jahe, sereh, dan pemanis alami dengan asam sitrat dan natrium bikarbonat masing-masing sebanyak 0,28 % dan 0,53%. Tahap keenam yaitu mengemas serbuk effervescent dengan aluminium foil kedap udara. Dari percobaan ini didapat bahwa nilai densitas larutan effervescent jahe dan sereh dengan penambahan gula pasir dan glukosa masing-masing sebesar 1,01 gram/ml dan 0,99 gram/ml. Hasil densitas ini lebih besar dibandingkan dengan hasil densitas larutan effervescent di pasaran yaitu sebesar 0,63 gram/ml. Hasil uji kecepatan pelarutan pada effervescent jahe dan sereh dengan variabel penambahan pemanis alami glukosa dan gula pasir masing-masing menunjukkan waktu 1,59 menit dan 1,37 menit. Hal ini sesuai dengan literatur yang menyatakan bahwa waktu pelarutan effervescent yang baik adalah selama 1 sampai 2 menit.


Alt. Description

The use of synthetic chemicals in the manufacture of effervescent causing concern the government will affect the health, so it is necessary to substituted the synthetic chemical with natural ingredients such as ginger, lemongrass, and natural sweeteners. The first procedures of effervescent ginger and lemongrass extract is to weigh as much as 167 g of lemon grass, to peel, to cut lemon grass, to heat the lemon grass with the addition of 2 l of water to boil, and then filter it. The second stage is to make ginger extract by measuring ginger to 1000 g, peel and wash it, crushing the ginger by adding lemongrass extract, and then heating the ginger and lemongrass extracts at a temperature of 100oC. The third stage is added the mixture of ginger and lemongrass extract with a natural sweetener such as sugar, glucose, and brown sugar each of 1765,1 g , and then stirred into caramel. Variable used is the type of natural sweetener ingredient is sugar, glucose, and brown sugar. A kind of natural sweeteners used has ratio of 1 : 1 (natural sweeteners : powder mixture). At the fourth stage, the caramel is naturally cooled to make powder and homogenized at 50oC into smaller particle size of 100 mesh. At the fifth stage, the product of effervescent is made by mixing the powder with citric acid and sodium bicarbonate respectively as 0,28% and 0,53%. The sixth stage of effervescent powder is packing it with airtight aluminum foil. From the experiments are obtained that the density of an effervescent solution from ginger and lemon grass with the addition of sugar and glucose are 1,01 g/ml and 0,99 g/ml respectively and itís density is higher than the commercial effervescent solution which have density at 0.63 g/ml. Test results on the dissolution rate of effervescent from ginger and lemon grass with the addition of variable natural sweetener such as sugar and glucose are respectively at 1,59 minutes and 1,37 minutes and those are matched with a reference with the optimum time of 1 to 2 minutes.
