How can we get long ambient shelf life at small scale?
Formulate and package soymilk in retortable bottles and sterilize them in a retort. VS30 and VS40 grinder cooker can be used as a retort for small scale production. Retortable pouches are also available but they require special retorts that prevent the pouches from bursting during the cooling phase by keeping the pressure outside the pouches always higher than inside. Retorting is frequently used also in older large scale plants ,especially in developing countries.
