When a food processing vessel under vacuum is repressurized, the tendency of product in the vessel to be forced into feed lines is relieved or overcome by establishing an effectively high pressure in the feed lines.

Embodiments herein include processing systems for food products and related methods. In an embodiment, a food processing system is included with a continuous processing channel divided into a come-up chamber, a main electromagnetic wave (such as microwave) heating chamber, and a cool-down chamber. The continuous processing channel can define at least two separate portions oriented for vertical product movement. In various embodiments, the come-up chamber, the main electromagnetic wave heating chamber, and the cool-down chamber are at least partially filled with liquid. The system can further include a product conveyor mechanism to convey food products to be processed continuously along a conveyance path passing from the come-up chamber through the main electromagnetic wave heating chamber and to the cool-down chamber. The system can further include an electromagnetic wave energy emitting apparatus configured to emit electromagnetic wave energy into the main heating chamber. Other embodiments are also included herein.

Methods and apparatus for sterilizing plant material include disposing plant material in a sub-atmospheric pressure environment, dispersing a non-toxic, non-polymerizable gas into the sub-atmospheric pressure environment, applying an electric field to change the gas into cold plasma, and maintaining exposure of the plant material to the cold plasma until substantially sterilized plant material is obtained, wherein an amount of at least one active constituent in the plant material is substantially unchanged by the sterilizing. The plant material may be Cannabis

Provided is a production method for a soluble material, including: causing a solid raw material containing at least one component of a hydrolyzable material selected from the group consisting of a protein, a carbohydrate and a lipid, and a fibrous material, and water in an amount corresponding to 0.04 to 2.4 parts by weight with respect to 1 part by weight of a dry amount of the raw material to coexist; applying a shearing force in a state where heating and pressurization are performed at 200 to 374° C. and in a pressure range equal to or higher than a vapor-liquid coexistence curve of water to hydrolyze at least a part of the hydrolyzable material and/or to amorphize at least a part of the fibrous material; and halting the pressurization to cause adiabatic expansion.

The present invention is direct to an co-fruit pulp based edible composition in which an agricultural fruit byproduct base material, in conjunction with a hydrocolloid, is treated with pressure and/or heat to form an edible composition that is dimensionally stable, ambient stable for at least 9 months, has a moisture content greater than 50 wt. %, has a pH less than 4.5, has a water activity greater than 0.5, is commercially sterile, is free of artificial flavors and/or artificial colors, has a solids content greater than 10 wt. %, and does not exhibit syneresis or exhibits syneresis. Alternatively, the base material contains an edible fruit and/or vegetable and/or nut byproduct alone or in combination with the co-fruit pulp. Also provided is a method for preparation of the edible composition.

An HPP system uses large polymer based bags (20) to increase the amount of food product or other flowable product that can fit into a HPP carrier (22). Each bag 20 has a filling fitment (24), to which a flow valve (26) can be attached. The bag (20) is inserted into the carrier (22) and then the fitment (24) is manually or automatically connected to a flow valve (26). Next, the product is pumped into the bag (20) through a hose or pipe (30) which is attached to the flow valve. Thereafter, the flow valve (26) is removed and the fitment closed, and then carrier (22) together with the bag is inserted into the HPP press for high pressure processing of the product. After the HPP process, the flow valve is used to un-fill the treated product from the bag (20).

A multilayer container for elevated temperature, high pressure processing of a material within the container, using a pressure transmission liquid within the container, the multilayer container having a container wall having an inner layer formed of a plastic for containing the liquid in contact with the inner side thereof and at least one further layer outboard of the inner layer and formed of different plastic from the inner layer, wherein the inner layer has a compression heating coefficient at least as high as the compression heating coefficient of the pressure transmission liquid in contact with the inner side thereof and the at least one further layer has a lower thermal conductivity at ambient pressure and temperature than the inner layer.

A method of heat-treatment of a product in a sealed container of a packaging material is described. The method includes placing the container in a treatment environment having a pressure (P) and a temperature (T), the pressure and the temperature having a ratio (P/T), and adjusting the temperature and/or pressure in the treatment environment to decrease the ratio over a duration in a time period. The time period starts at a time of cooking onset of the product and extends over a time of cooling onset at which time a temperature decrease is started, the time of cooking onset being preceded by a first time period of temperature ramping during which the temperature is increased. An apparatus for controlling heat-treatment of a product in a sealed container of a packaging material is also described.
