Guillemin,
Degraeve, Noel, and Saurel (2008) performed a sodium chloride
and/or sodium alginate VI treatment under 0.05 bar for 2 min, for
apple cubes, in order to improve the firmness. Sapers Garzarella,
and Pilizota (1990) used a 2 min vacuum time, at 169–980 mbar
pressures, for NaCl VI treatment of diced or strip potatoes.
