The present invention discloses a microwave and conduction combined heating method for improving the gel strength of surimi products, belonging to the technical field of food processing. According to the present invention, surimi is first fully gelatinized by conduction heating, and then heated by microwave heating so that surimi gel can pass through a gel cracking zone quickly. This kind of microwave and conduction combined heating way can not only increase the gel strength of the surimi to achieve the desired elasticity, but also can save a lot of time and improve the production efficiency. Compared with ordinary microwave heating, the microwave and conduction combined heating method of the conduction and microwave heat preservation, i.e. holding the temperature of the surimi products for a period of time by adjusting the microwave power level at a specified temperature range, can effectively improve the gel strength of the surimi and comply with the new trend of applying microwave heating to surimi products.

A product for cooking a food in oil and/or fat is provided. An adjusted pH protein suspension is produced in an aqueous or dry form and includes myofibrillar proteins and sarcoplasmic proteins substantially free of myofibrils and sarcomeres. The amount of oil and/or fat absorbed by the food during cooking is substantially reduced while the food retains its color and taste.

Disclosed is a baked food which comprises a cereal flour, an oil or fat component, astaxanthin and optionally an emulsifying component, has such a structure that the oil or fat component containing the astaxanthin is held in voids in a structure formed by a starch of the cereal flour, and has a porosity of 10 to 70%. Specifically disclosed is a baked food produced from an astaxanthin-containing dough, which can stably hold astaxanthin therein for a long period.
