摘要:
Methods of sterilizing a temperature sensitive material, such as an acidified or non-acidified food product, pharmaceutical product or cosmetic product, are disclosed. The methods comprise freezing the temperature sensitive material to an initial temperature of less than or equal to −2° C. and then either (i) pressurizing the frozen temperature sensitive material to a first elevated pressure of at least 250 MPa for a predetermined first period of time of at least 3 minutes or (ii) pressurizing the frozen temperature sensitive material to a first elevated pressure of at least 250 MPa for a predetermined first period of time of at least 90 seconds, releasing the first elevated pressure for a predetermined pause period of time and then pressurizing the temperature sensitive material to a second elevated pressure of at least 250 MPa for a predetermined second period of time of at least 90 seconds.
摘要:
A shelf-stable acidified food product having an edible food and two or more acidulants with sufficient acid to achieve a pH below 4.6. The two or more acidulants are admixed with the edible food in an amount effective to adjust the pH of the food product to the range of 3.8 to 4.5. In some embodiments, the two or more acidulants comprises gluconic acid and sodium acid sulfate.

A food product is provided that is formed from dehydrated fruit to form a crust for pies, wraps, and the like in which the dehydrated fruit has a water activity level in the range of 0.4 to 0.9 Aw. The dehydrated fruit can be ground into particles that are extruded, compressed, rolled, or stamped into a sheet that is cut into top and bottom crusts. Dehydrated fruit particles having a water activity level of 0.1 to 0.2 Aw can be used to form a cracker-like crust. The fruit-based crust can be used to form an all-fruit pie or similar-type pastry.
摘要:
A process for the aseptic preparation of particulate food products containing large and minor particulate components. The large and minor particulate components are separately heated within a single processing system at a temperature and time sufficient to sterilize each component. The large component may be acidified prior to heating and recombined with a heated minor component at basic pH to form a sterilized food product at neutral pH.

摘要:
An acidified, milk-based, shelf-stable food product comprises a milk-based component and preferably a pasta component. At least the milk-based component contains acidifying agents selected from the group of sodium acid sulfate, sorbic acid, lactic acid, and gluconic acid. This unique combination of acids provides a salty flavor without the addition of sodium chloride and provides an end product having a low pH or low acid taste that is shelf-stable over a significant period of time.
摘要:
This invention pertains to methods for achieving the commercial sterilization of foods having a pH greater than or equal to 4.5 involving concomitant treatment of the food to two or more cycles of high heat, high pressure, with a brief pause between cycles. The pressurization schedule relies on the additional instantaneous, uniform.

This invention pertains to methods for achieving the commercial sterilization of foods having a pH greater than or equal to 4.5 involving concomitant treatment of the food to two or more cycles of high heat, high pressure, with a brief pause between cycles. The pressurization schedule relies on-the additional instantaneous, uniform heat from adiabatic pressurization and then instantaneous, uniform adiabatic cooling during depressurization for each cycle.
摘要:
A fat substitute composition includes an edible, substantially non-digestible fat substitute material having a melting point of about 37.degree. C. or less in combination with an emulsifier as an anti-laxative agent to reduce an undesirable laxative effect associated with the fat substitute material. In a preferred embodiment, the emulsifier is present at a level of greater than 5% by weight of the fat substitute material.
