Abstract: The invention provides a bread with D-allulose instead of sucrose and a preparation method therefor, and relates to the technical field of food processing. The starting materials include, in parts by weight: 40-60 parts of flour, 3-5 parts of gluten powder, 5-10 parts of D-allulose, 5-10 parts of eggs, 5-10 parts of milk, 3-5 parts of yeast, 4-6 parts of butter, 0.4-0.6 parts of composite bacterial powder, and 15-25 parts of water. The yeast is fresh yeast. The composite bacterial powder includes one or more of Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus rhamnosus, Bifidobacterium longum and Bifidobacterium lactis. Replacing sucrose with D-allulose in bread does not affect the normal proofing of bread dough, and the baked bread is fluffy and soft, sweet, and delicious, has good color, aroma, and taste. Because D-allulose has the advantages of low calorie and low blood sugar response, consumers' pursuit of “healthy eating” is met.

Abstract: This disclosure describes systems and techniques for identifying events that occur within an environment using image data captured at the environment. For example, one or more cameras may generate image data representative of a user interacting with an item on the shelf. This image data may be used to generate feature data associated with the user and the item, which may be analyzed by one or more classifiers for identifying an interaction between the user and the item. The systems and techniques may then generate interaction data, which in turn may be analyzed by one or more additional classifiers for identifying an event, such as the user picking a particular item from the shelf within the environment. Event data indicative of the event may then be used to update a virtual cart of the user.
