  • Popcorn is a highly popular snack food item.
  • the at-home preparation of popcorn by the consumer involved adding kernel popcorn plus a cooking oil to a covered pot and heating until the popcorn kernels popped to make popcorn.
  • kernel popcorn refers to unpopped popcorn.
  • popped popcorn refers herein to popped kernel popcorn.
  • the adjective “popcorn” can refer to either. Once prepared, common, relatively coarse, table salt is a frequently added flavoring or condiment. The resultant salted popped popcorn is a familiar snack food.
  • microwave popcorn products comprise an expandable paper bag containing a charge of kernel popcorn, and optionally fat and/or salt.
  • the microwave popcorn article is adapted to be heated in a microwave oven for three to five minutes to produce the popped popcorn.
  • improved microwave popcorn articles have been fabricated employing a metallized susceptor which facilitates the heating of the kernel popcorn- fat charge and which, in turn, leads desirably to increases in popcorn volume and decreases in unpopped kernels.
  • Microwave popcorn articles of this type are described in detail in, for example, U.S. Pat. No. 4,450,180 (issued May 22, 1984 to J. D. Watkins and incorporated herein by reference).
  • the fat component is generally flavored with artificial butter flavor although microwave popcorn with real butter products are known and commercially available (see US 5,919,505 "Shelf-Stable Butter Containing Microwave Popcorn Article and Method of Preparation” issued Jul. 6, 1999 to Monsalve et al).
  • Sweet popcorn products or "kettle corn” popcorn are well known.
  • caramel popcorn has long been a popular food item.
  • Such products generally comprise a sweet coating, typically from sucrose and/or small amounts of brown sugar and/or sugar based syrups such as molasses or black strap sugar syrup to provide a caramel flavor and that can also contain butter and/or other fat(s).
  • Bulk amounts of popcorn are prepared (sometimes admixed with nuts) and the sugar-based coating is applied thereto by manufacturers to make the caramel popcorn. Quantities are provided in suitable consumer packaging such as bags whether or not in cartons or other suitable containers, e.g., plastic tubs. Various amounts of salt are added to provide a merely sweet to a sweet-and-salty flavor. With lesser amounts of coating, the coated popcorn can be free flowing. With more coating, agglomerated pieces or even popcorn balls are made.
  • Microwave products for preparing sweetened puffed products are known (see for example US 4,409,250 to Van Hulle et al).
  • sweet microwave puffed products comprising sugars can exhibit scorching or even runaway heating due to the high microwave absorption by sugars and salt and the low browning or burning temperatures of sugar.
  • the microwave bag can actually ignite due to the burning sugars.
  • Sugar scorching problems are aggravated by salt, making provision of "sweet and salty" products (i.e., products having a more pronounced salt flavor due to higher levels of salt) especially difficult. The excessive heat can also scorch the popcorn.
  • One approach for providing a microwave popcorn product having a sweet or cheese coating that does not scorch or burn during microwave popcorn popping is to separately package the coating from the microwave popcorn for post popping addition thereto (see for example, US 4,904,488 "Uniformly-Colored, Flavored, Microwaveable Popcorn" issued Feb. 27, 1990 to LaBaw et al).

  • the coating feature ingredients are selected to include a low moisture coarser granulation sugars in combination with selection of a low melting point oil and salt and moisture level control to provide a microwave sweet popcorn product.
  • Another technique for providing a sweet microwave popcorn product is to employ in substitution for low temperature burning temperature sugars a sweetening agent that exhibits greater tolerance to higher temperatures such as acetylsulfame K and/or Sucralose. Sucralose was not approved for use in microwave popcorn products in the United States until August 1999 when sucralose was approved for use for all food categories. Soon thereafter, several microwave popcorn manufacturers began marketing sweet or "kettle corn" microwave popcorn products (see for example, published US patent application US
  • Such products generally employ low levels of the intensely sweet sucralose typically dispersed or diluted in small amounts of a heat tolerant powdered carrier or diluent such as a maltodextrin and avoid inclusion of temperature sensitive sugar ingredients. While useful, the sweetened microwave popcorn prepared from such microwave popcorn products lack the quantity of coating or glaze typical of bagged popped caramel popcorn and thus the eating qualities of such heavily coated sweet products. Also, sucralose is a high value, high cost ingredient.

  • the food charge also includes at least one flavoring that is not in the slurry, but instead is in separate packaging that is also within the food bag.
  • the flavoring container is further away from the susceptor and therefore its contents absorb less heat than they would if included in the slurry. The flavoring container intentionally fails during the popping process, thereby delivering its contents to the popping corn.

Broadly, the popcorn can range from about 30 to 90% of the popcorn charge. Typically, about 15 to lOOg of kernel popcorn is added to the bag, preferably about 50 to 70g/bag for regular sized products and about 25 to 40g/bag for "single portion" sized products. In general practice, the amount of kernel popcorn is set and the other ingredients are varied to provide variations such as full fat, reduced or low fat, and/or salted or low salt embodiments.
  • microwave popcorn is dried to moisture contents ranging from about 10% to 18%), preferably about 12% to 16%> and for best results about 14% to insure sufficient moisture for popping of a high fraction of kernels while minimizing moisture that might cause or promote bacterial growth during the long term distribution and storage characteristic of shelf stable packaged products. It should be noted that some flavorings are intolerant to moisture, whether during storage or popping, so containing them separately from the other ingredients of the popcorn bag as described herein can help retain quality and intensity of such flavors.

  • flavoring container 82 is disposed in a manner such that much of the flavoring within the container is relatively distant from the face panel 24 including the susceptor of bag 12, thus resulting in less heat being transferred to the flavorings within container 82 than if they were mixed in with slurry 81.
