It is an object of the present invention to provide a method and the like capable of producing a large amount of fructooligosaccharide-containing oil-based confectionery having low hygroscopicity. In the method for producing fructooligosaccharide-containing oil and fat according to the present invention, fructooligosaccharide is pulverized with at least the oil and fat and an emulsifier in a closed system pulverizer to obtain fructooligosaccharide-containing oil and fat. Then, a fructooligosaccharide-containing oil-based confectionery can be produced from the fructooligosaccharide-containing oil-based confectionery base obtained by mixing the fructooligosaccharide-containing oil and fat with the oil-based confectionery base or the raw material thereof. This fructooligosaccharide-containing oil-based confectionery has extremely low hygroscopicity, and if stored in a good environment, the moisture content can be kept extremely low at the point of 210 days from the time of production.

The present invention relates to the field of food processing and provides a method for preparing olive leaf powder, including the following steps: pulverizing olive leaves under conditions protected from light to obtain crushed olive leaves; immersing the crushed olive leaves in water, and homogenizing, to obtain an olive-leaf homogenate; pre-freezing the olive-leaf homogenate at a temperature below 16 C. for more than 25 min, and then vacuum freeze-drying to obtain the olive leaf powder; where the vacuum freeze-drying is performed according to the following: the olive-leaf homogenate is heated at a constant rate from the pre-freezing temperature to a drying temperature, and is dried at this temperature for more than 20 min to obtain the olive leaf powder; and the drying temperature is 15-35 C. In the present invention, the olive leaves are subjected to pulverization and homogenization before the freeze drying, such that by changing the sequence of pulverization and freeze-drying, the freeze-drying efficiency is effectively improved and the energy consumption during freeze-drying is reduced, thereby reducing the freeze-drying cost; and the present invention effectively preserves active substances of the olive-leaf powder, such as the total flavonoids and oleuropein, and improves the reconstitution property of the product, thereby effectively achieving a balance between the quality of the olive-leaf powder and the processing cost.
