Patent CA-2025546-A1 (CA)
Inventor: VAN HETEREN JAN
IPC: A23D7/01
Filed: 1990-09-17
Abstract: ABSTRACT      The present invention is concerned with a spread comprising less than 30 wt.% of a continuous fat phase and at least 70 wt.% of an aqueous phase, wherein the spread comprises 0.1 to 1.5 wt.% of a mixture of monoglycerides and polyglycerol esters in a weight ratio of monoglycerides to polyglycerol esters in the range of 1:10 to 10:1.      The spreads according to the present invention offer the advantage that processing conditions to be used in manufacturing said spreads are not very critical. After processing, the present spreads are comparatively more stable towards phase inversion than similar spreads containing solely monoglycerides or polyglycerol esters. Furthermore the utilization of mixtures of monoglycerides and polyglycerol esters enables the preparation of very low fat spreads containing a substantial amount of non-gelling protein.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved form, fill, seal and separate packaging machine (10) for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web  (12)  including means  (19)  to attach a pair of mated, resealable closure strips to the base web.  The machine is intermittent in its operation, with movement of the web (12) through the machine con-trolled so that the various steps of applying the closure strips,  forming,  filling,  sealing and separating the reclosable containers are performed during periodic stops of  the machine  (10). The machine  (10)  is  further characterized by its use of two pairs of web belts (26, 28 and 82, 84) to move the web (12) through the machine (10).   A first pair of web belts  (26,  28)  initially receive the folded web stock and partially form and completely fill the containers.  The second pair of web belts (26, 28) overlap with the downstream end of the first pair of belts (26, 28), but are disposed lower than the first belts  (26, 28).   When the filled partially formed containers pass from the first pair of belts (82, 84) to the second pair of belts, the unsealed free ends are exposed for final sealing and severing.
