Abstract

Khoa (conc. milk) of good quality with proper consistency was prepared by using steam to concentrate the milk instead of coal or gas fired hearths and by using stainless steel, jacketted open kettles in place of traditional hearths. In large scale (50 l) operation preliminary concentration (30-40 degree Brix) was carried out under vacuum (620 mm Hg, 0.2-0.3 kg/cm-2 steam pressure) in forced circulation evaporators, with final concentration in open kettles. Burfi was prepared by adding sugar to the khoa (1:2) and 0.15% sorbic acid; 25% sugar was also replaced by liquid glucose in one batch. The products were packaged in MSAT cellophane, low density polyethylene (LDPE 400 gauge), high density polyethylene (HDPE 300 gauge), MSAT + HDPE, glassine/polyethylene (PE), Saran/Cellosaran/PE laminate, paper/Al foil (150 gauge), and a Polycel inner and PE outer pouch. Sensory evaluations were carried out after 50 days storage at 20 degree or 27 degree C, and compared with those for market burfi (made without the sorbic acid and sugar). Best results were obtained with addition of sorbic acid and packaging in the Polycel/PE pouch; the burfi kept for 90 days (instead of 6-8 days with traditional methods). Addition of liquid glucose was not necessary with this package.
