Pengaruh Perendaman Dengan Asam Sitrat Terhadap Karakteristik Gelatin Tulang Ikan Tuna (Thunnus Albacares)

---

Tuna is generally used in the canning and freezing industry. The by products of
processed tuna which are not utilized such as the head, bones and skin are processed
into flour and the skin and bone can also be used as gelatin. The process of making
gelatin through several stages, namely by immersing the sample (tuna fish bone) in
citric acid is called type A gelatin. This study was aimed to determine the
concentration of citric acid, yield, physical-chemical characteristics and sensory
gelatin of tuna fish with immersion in citric acid. This study uses an experimental
method with non-factorial Completely Randomized Design (CRD). The treatment
was given by soaking tuna fish bones in citric acid with a concentration of 6, 9 dan
12%. Parameters of analysis were consisted of yield, moisture, ash content, gel
strength, viscosity and sensory test. The result of gelatin analysis with immersion in
citric acid 6, 9 and 12% were resulted in yield, moisture content and ash respectively
3.09, 5.29 and 7.12%. 3.93, 5.06, 3.97% and 10.55, 7.83, 6.94%. physical
characteristics of gelatin with citric acid 6, 9 and 12% was produced 8.75, 17.19,
15.59 g bloom and 1.91, 1.90, 1.97 cP. The result of the sensory analysis of gelatin
was produced meet Indonesia Pharmacopoeia standart (tasteless, smelly, and
yellowish). Soaking with citric acid significantly affected the yield, moisture and ash
content but did not significantly affect the gelatin viscosity and gel strength.
