Freshness estimation fishes out that easiest being done until currently is sensori estimation covers performance, color, flavour, and texture. Besides needed also laboratory
which is equal to and tool and material that don't be had by one any one, so along with technology developing is required a practical tool to detect fish freshness one easy way
and quick. That tool gets to get little tag abatamen form that resident deep pack. This smart tag can give information to consumer hits fish quality that packed by discoloration,
so consumer gets to know quality decrease fishes out that will be bought. Flesh processing industry a lot of develop method to evaluate freshness from product. One of it by features lapse date, but date of lapse can't inform storage fault. Smart packaging development as indicator of antosianin's color from red cabbage can monitor flesh quality if most tall temperature flat and at the moment storage. In extraction does this research cabbage
tingles to result antosianin ekstract that following is expected get as been utilized colour indicator film in shaped kitosan PVA film (Polivinil is Alcohol) with natural colouration from red cabbage. Ektract method that is utilized variation which is (1) Maserasi's Methods – Sonikasi; (2) Maserasi's Methods plain; (3) Poaching Methods; and (4) Poaching Method – Kopigmentasi. Cabbage colouration extract best red to be gotten from maserasi's method – Sonikasi with so long extraction 60 minute has pH 4.63 by total 1553.33 mg antosianin / 100 g fresh red cabbages. Colour intensity extracts antosianin cabbage tingles to point out °hue's Point as big as 281.4 bases Munsell's diagrams, this °hue's point lies on blue purple gyration (PB). Meanwhile Total padatan extracts antosianin cabbage tingles that acquired is as big as 72. 22 ± 0,007%, meanwhile resulting rendemen amount as big as 28,34%. From acquired data to be concluded that extraction result with maserasi's method – sonikasi can be drawned out as film of cabbages colour indicator tingle that get as been applied smart packaging to detect flesh damage.
