Tasteful Crackers made of Dregs of Soybean Juice A la IPB
Soybean juice is one of diversified soy products in the form of beverages derived from soybean extract. Soy is useful in lowering and controlling blood glucose levels. This is because the soybean juice is rich in lecithin, arginine, and glycine and contains isoflavones that can lower blood cholesterol levels.
Processing of soy essence is done by grinding and filtration to obtain filtrate. This processing produces by-products called soybean dregs. To date, soybean dregs produced is used only as animal feed, although it actually has a good nutritional content such as protein, fat and food fibres.
Soybean dregs have potential to be used as processed food because it contains high fibre and protein components. Therefore, this can increase the added value of soybean dregs and apply zero waste so that no waste is produced from making soy essence.
This underlies the implementation of a study conducted by the research team from the Department of Food Science and Technology of Bogor Agricultural University (IPB), namely Prof. Rizal Syarief and Zufita Wahidatur Rohmah, using the soybean dregs as a substitute material in the production of catfish crackers.
Crackers are one of the most popular snacks in Indonesia due to its savoury taste and crunchy texture. Generally, crackers are used as a side dish or as a snack. Fish crackers is one type of crackers that are quite popular because of the abundant availability of raw materials in the form of fish including catfish.
Catfish is selected as raw material in the production of crackers because the catfish production increases every year. In addition, many catfish are cultivated and consumed in Indonesia. To date, the catfish processing is not maximized and it is usually only fried. Therefore, the processing of catfish in another form such crackers is needed to establish.
The research result showed that the best formula was the 2nd formula with substitution of soybean dregs flour of 20%. The selected formula had 1.50% moisture content, 3.17% ash, 14.78% protein, 17.95% fat, 64.10% carbohydrate, and 10.21% crude fibre. (TK)
