摘要:
A method for reducing the amount of asparagine, a pre-cursor of acrylamide, in food products that are thermally processed. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on contacting a potato feed such as potato slices containing asparagine, an acrylamide pre-cursor, with a leaching solution to extract asparagine out of the potato feed. Thermally processing the leached potatoes will result in a potato product having a lower level of acrylamide than a non-leached, thermally processed potato product.
摘要:
A process and apparatus for a method for reducing the amount of acrylamide in thermally processed foods. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on the manipulation of various unit operations used in the production of food products, particularly the washing and cooking unit operations. For example, the washing unit operation can be modified to provide a contacting step at an increased time and temperature, and adding components such as calcium chloride and L-cysteine to an aqueous solution used for the contacting. The cooking unit operation can be modified by dividing it into at least a higher-temperature first heating step and a lower-temperature second heating step in order to avoid the high-temperature/low-moisture conditions most favorable for acrylamide formation.
摘要:
A method for reducing the amount of acrylamide in thermally processed foods. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on the manipulation of various unit operations used in the production of food products, particularly the peeling, cooking, and rejecting unit operations. For example, the peeling unit operation can be modified to provide a more fully peeled potato slice. The cooking unit operation can be modified by cooking to higher moisture and/or at lower hot oil temperatures to minimize the high-temperature/low-moisture conditions most favorable for acrylamide formation. The rejection unit operation can be modified to reject defects that result in high levels of acrylamide.
摘要:
A method for making a direct expanded snack piece shaped like a peanut is disclosed. Ingredients comprising peanut flour, ground corn product, rice flour and oat flour are introduced into an extruder. The ingredients are hydrated and extruded through an orifice adapted to produce a puffed snack piece shaped like a peanut and cut into puffed snacks. The puffed snacks are dried and seasoned.

An extruder die assembly and method for using same is disclosed which is designed for adaptation to a wide variety of commercial-grade extrusion devices common in the food industry. The extruder die assembly is inserted into an appropriate compartment within an extrusion device such that a first extrudate is directed down a coaxially aligned passageway within the forming section and combined with a fluid additive in the injection section whereupon the resulting food mass is compressed through a converging nozzle bore in the nozzle section to produce an extruded food product. The forming section and injection section are fabricated as a matching set. The matched set, comprising the forming section and the injection section, when properly aligned and coupled form an internal peripheral reservoir manifold through which a fluid additive may be supplied to at least one and more preferably a plurality of capillary channels which in turn impart a distinct cross-sectional design into a flowing mass of a first extrudate.

The present invention discloses formulations for vacuum baked fruit and vegetable snack pieces that have a crispy, crunchy texture similar to potato chip, corn based wafers, and other popular snack items. A fruit or vegetable base is combined with other ingredients and water to make a slurry, which is sheeted and dried in a vacuum belt dryer, and separated into snack sized pieces. In one embodiment, substantial amounts of solid inclusions are combined with the slurry before drying.

A method is disclosed for producing an intermediary product in the form of a nut-based pellet that is capable of being stored for up to about six months. To form the nut pellets, a nut dough is passed through an extruder. The extrudate produced is then cut into pellets and dried. Starch pellets can then optionally be mixed with the nut pellets or small nut pieces and cooked to form a snack chip. The snack chip is formed by compressing and cooking the pellet mixture, expanding the pellet mixture, and compressing the pellet mixture again.
摘要:
The invention allows for a reduction in the amount of salt topically applied to a food product with an oil layer on its outer surface, without adversely affecting the taste of the food product. Salt particles with a particle size greater than the thickness of the oil layer are topically applied to the food product. Because substantially all of the salt particles protrude from the oil layer, they provide a saltiness perception having no meaningful difference from the saltiness perception provided by a control salt applied at higher levels.

摘要:
A method is disclosed for producing a baked snack chip made from a raw potato slice. The snack chip has a light, crispy, expanded texture similar to the texture of a fried potato chip. It is formed by compressing and heating a partially dried potato slice and then expanding the potato slice. Alternatively, the expanded potato slice is compressed again.
