  • Patent number: 7387809
    Abstract: The present invention relates to an improved binder system to stabilize and improve yield for thermally processed meat products such as those that are used in canning or retort operations. More specifically, the present invention pertains to the novel starch/binder matrix that produces a meat product having enhanced moisture flavor and texture over those treated using currently available techniques. The novel matrix uses a combination of starches that provide differential water holding and moisture control for the meat products treated therewith.

  • Patent number: 6451121
    Abstract: Thermally-inhibited starches and flours which are functionally equivalent to chemically-crosslinked starches are prepared by a process which comprises the steps of dehydrating a granular starch or flour to anhydrous or substantially anhydrous (<1% moisture) and heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch, (e.g., 120-180° C. for up to 20 hours). Preferably the pH of the starch is adjusted to neutral or greater (e.g., pH 8-9.5) prior to the dehydration. The dehydration may be a thermal dehydration carried out simultaneously with the heat treatment or a non-thermal dehydration carried out by extraction with a solvent (e.g., ethanol) or by freeze drying.

  • Publication number: 20020009239
    Abstract: A plastic bag comprises opposing body panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. A reclosable zipper extending along a mouth portion formed opposite the sealed bottom of the plastic bag. The zipper is preferably free of graspable upper pull flanges in order to best accommodate a slider and inhibit operation of the zipper without the slider. The slider is mounted to the zipper for movement between a closed position and an open position. The zipper is closed while the slider is in the closed position. The zipper is opened in response to movement of the slider to the open position. To inhibit tampering with the contents of the bag, the bag includes a tamper-evident feature. In one set of embodiments, the tamper-evident feature initially maintains the slider in the closed position and allows the slider to move away from the closed position toward the open position in response to removing or breaking the tamper-evident feature.

  • Patent number: 6261376
    Abstract: Thermally-inhibited, pregelatinized non-granular starches and flours are prepared by pregelatinizing the starch or flour and thermally inhibiting the starch or flour by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch. The pregelatinization may be carried out prior to or after the thermal inhibition using known methods which disrupt the granular structure such by drum drying or jet cooking and spray-drying. Preferably the starch or flour is adjusted to a pH above 7.0 prior to the thermal inhibition. The starch may be dehydrated by heating the starch in a suitable heating apparatus, by extracting the water from the starch using a solvent such as ethanol, or by freeze drying the starch. Preferably the starch or flour is treated with a solvent to remove proteins and/or lipids and thus prevent off flavors.

  • Patent number: 6221420
    Abstract: A thermally-inhibited granular starch or flour is used as an ingredient in various foods. The thermally-inhibited starches are functionally equivalent to chemically cross-linked starches. The stashes or flours are prepared by dehydrating the starch or flour to anhydrous or substantially anhydrous (<1% moisture), preferably at a neutral or basic pH, and heat treating the dehydrated starch or flour for a time sufficient to inhibit the starch to the desired degree. The dehydration may be carried out by heating the starch, extracting the starch with a solvent, or freeze drying the starch. The starch may be pregelatinized prior to or after thermal inhibition using known methods which do not substantially rupture the starch granules.

  • Patent number: 5830884
    Abstract: Thermally-inhibited starches and flours are used in pharmaceutical products as a diluent, filler, carrier, binder, disintegrant, coating, thickener, moisture sink, and the like. The starches and flours are inhibited by dehydrating the starch or flour to substantially anhydrous or anhydrous and then heat treating the anhydrous or substantially anhydrous starch or flour for a time and at a temperature sufficient to inhibit the starch or flour. The dehydration can be carried out by heating the starch or flour, by extracting the starch or flour with a solvent, or by freeze drying. Preferably, the pH is adjusted to a neutral pH or above prior to the dehydration and heat treatment.

  • Patent number: 5718770
    Abstract: Pregelatinized granular starches and flours are thermally inhibited by dehydrating a starch to anhydrous or substantially anhydrous and then heat treating the dehydrated starch at a temperature and for a time sufficient to inhibit the starch. The starch may be pregelatinized prior to or after the thermal inhibition using methods known in the art which retain the granular integrity. Preferably, the pH of the starch or flour is raised to 7.0 or above prior to the thermal inhibition steps. The dehydration step may be carried out by directly heating the starch, by extracting the starch with a solvent, or by freeze drying the starch. Preferably protein and/or lipids are removed prior to or after the thermal inhibition.
