How to dissolve

Handling Directions

Recommendation for dispersion and solubilisation

A proper solubilisation of Sunri gelatines is critical for reaching the complete development of their functionalities. There are four main dissolution methods, allowing the preparation of up to 40% gelatin solution:

Conventional method:

Sunri gelatin is first swelled in cold water (30 minutes to 1 hour) and then dissolved by heating in a water bath

High speed method :

Sunri gelatin is directly dispersed in hot water (80-90°C) with appropriate high-speed stirring. Once dispersed, it will dissolve under slow agitation (5 to 10 minutes)

Intermediate method:

Sunri gelatin is swelled in cold water (30 minutes to 1 hour) and then dissolves by addition to hot ingredients

Dissolution of mixes:

For fine particle size, Sunri gelatin is mixed to other dry ingredient before dissolution

Preserve viscosity and gelatin characteristics

While gelatin is very stable in its gel form, various factors such as pH, temperature or bacterial environment may cause an hydrolysis of the protein chain yielding a decrease in viscosity and Bloom. It is thus very important to protect the solution against elevated temperature and at extreme pH for extended periods of time.

Cleaning Procedures:

Washing the equipment used for processing gelatin based products, is essential for maintaining good hygiene conditions and is easy to perform since gelatin is highly soluble in water.

For a batch process, the cleaning is done by washing, soaking or immersion of the equipment:

· Always start washing with very hot water, at least 80°C, to let swell and solubilize a maximum of residual gelatine

· Then the equipment is cleaned with a 2 to 5% soda solution, maintained at 60-80°C for 30 minutes for a total destruction of organic matters. (This treatment is possible only for stainless steel or glass)

· Finally, an acid treatment with an acid diluted bath (3 to 5‰) at 60 to 80°C will destroy mineral matters if any

· After each alkaline or acid bathes, the equipment is rinsed with hot water and the pH is measured ( to come back to neutrality)

· At last, if bacteriological problems occur, a disinfection of the equipment is possible, with a thermal treatment (steam or boiling water) or chemical treatment (ex sodium hypochlorite at 1 to 2% in concentration) followed by a rinsing step

Recommendations:

· The equipment has to be cleaned as much as possible and usually a daily cleaning is suited

· Cleaning and disinfection are suited after every accidental stop

Disinfection is unnecessary without a previous cleaning procedure
