Abstract:
The present invention relates to an air-based fryer (10) apparatus comprising a food preparation chamber (140) comprising an outer wall (11), an inner wall (14) defining a food receiving space (141) with an air inlet (142) and an air discharge opening (145), and a circulation channel (113) defined between the outer wall (11) and the inner wall (14). The apparatus also comprises an air heater (13) for heating air in the food preparation chamber (140), a fan (192) for moving a flow of hot air successively through the air inlet (142), the food receiving space (141), the discharge opening (145), and the channel (113). The apparatus also comprises a steam generator (12) comprising at least one nozzle (127) extending into the food receiving space (141) for spraying temperature-controlled steam (18) onto the food; and a controller (15) adapted to control the steam generator to spray steam to food placed in the food receiving space (141) for a first predetermined period, and to control the air heater (13) and the fan (192) to circulate hot air to the food for a subsequent second predetermined period. This apparatus allows keeping the tenderness or crunchiness of the food during subsequent hot air cooking.
Abstract:
The present invention relates to an air guide member (10) for an apparatus for preparing food by circulation of hot air in a food preparation chamber, the air guide member comprising, an air deflecting structure(12), a protected region (14)for collecting residual material from the food preparation chamber. The air deflecting structure(12) has a deflection surface (18) with a deflection orientation (20) that leads away from the protected region(14). The invention also relates to an apparatus implementing this air guide member. This invention prevents or reduces generation of fumes during cooking.
Abstract:
The present invention proposes a method for reducing acrylamide content in food, comprising soaking said food in acid solution in a food treatment device, wherein said acid solution has a pH value range from 2.7 to 4; and applying, by the food treatment device, a direct current to the solution, wherein said the direct current ranges from 0.1 to 3.0 Amperes. The present invention also provides an apparatus for performing the above method.
Abstract:
The present invention provides an apparatus for cooking which comprises a holding unit configured to hold and heat said food; and an induction heating unit positioned in a distance from said holding unit, configured to heat up said holding unit; wherein said holding unit is configured to have melted fat of said food removed off said holding unit to avoid heating the melted fat. By using such an apparatus, concentration of heterocyclic aromatic amines and polyaromatic hydrocarbons in cooked food could be reduced.
Abstract:
The present invention proposes a method for cooking to reduce acrylamide concentration in food. By using such a method, food is cooked at a relatively lower temperature first and then cooked at a relatively higher temperature, to avoid the temperature range within which the concentration of acrylamide formation is higher than a pre-determined level, without affecting the desired appearance, flavor or texture of the food. The lower temperature is at most 140 degrees Celsius, in particular no higher than 120 degrees Celsius, and the higher temperature is at least 180 degrees Celsius, in particular no lower than 200 degrees Celsius. The invention also provides an apparatus for cooking using the above described method.
Abstract:
Embodiments of the present invention relate to freshness indication. In some embodiments, a freshness indicating device is provided. The freshness indicating device comprises a collector and an indicator. The collector is adapted to collect water from an object. The object includes at least one of fruits and vegetables. The indicator is adapted to indicate the freshness of the object based on the amount of the collected water. A corresponding method and a container comprising the freshness indicating device are disclosed as well.
Abstract:
A freshness detection device (10) which comprises a container (20) adapted to form an accommodating space (11) for accommodating an object; a heat transferring surface (21) contacting the accommodating space (11); a sensing unit (30) adapted to provide a sensing parameter representing the heat transfer amount through the heat transferring surface (21); and a processing unit (40) adapted to determine the freshness of the object based on the sensing parameter. This provides a non-invasive and efficient way for consumers to detect the freshness of fruits, vegetables, flowers, mushrooms, etc.
Abstract:
A soymilk maker (10) is provided, which comprises a roaster (12) configured to roast raw soybeans or soybean particles to inactivate anti-nutrients; a container (14) comprising a grinder configured to grind and a cooker configured cook the roasted soybeans or soybean particles; and a control unit (16). The soymilk maker (10) further comprises a sensing device (18) configured to sense the moisture content of the soybeans or the soybean particles in the roaster (12), and the control unit (16) generates a signal for stopping roasting when the output of the sensing device (18) with respect to the moisture content of the soybeans or the soybean particles in the roaster (12) reaches a predetermined value.
Abstract:
The present invention proposes a method for determining water content of food in a container. The method comprises steps of measuring (302) relative humidity values of air in the container before a water exchange equilibrium state is reached and calculating (304) water activity based on such relative humidity values, and determining (306) water content of the food based on the water activity. The present invention also provides an apparatus for determining water content of food using the above described method.
