A collapsible bag is disclosed having a handle and a compartment attached to the handle, the compartment formed of nine panels comprising front and back trapezoidal panels, a rectangular bottom panel, and left and right triangular expansion zones, each triangular expansion zone formed by an isosceles lower triangular panel and first and second congruent, scalene triangles. The expansion zones occur below a midpoint of the height of the compartment and distributes more space near the bottom of the bag while narrowing the bag at the top of the compartment. Moreover, the distance between the top of the isosceles triangular panels when the bag is open is greater than a width of the rectangular bottom panel and less than the handle width.

The invention discloses a food storage container which comprises a liquid storage container and a body. The liquid storage container is opened at the upper part and is provided with at least one placement part; the body is detachably connected into the liquid storage container in a sleeved mode, and at least one containing area and a matching part matched with the placement part are formed on thebody; the bottom of the containing area protrudes upwards to form a containing platform, a liquid channel is formed between the containing platform and the inner side wall of the containing area, andat least one opening is formed in the end, away from the containing platform, of the liquid channel, and the body is in different placement states by configuring the corresponding matching mode of thematching part and the placement part. According to the food storage container, conversion of different placement states can be completed only by lifting the body and moving the body, operation is convenient, and the demands for storage, heating and eating of foods needing to be boiled in water can be conveniently and integrally met.

The invention discloses a new quantitative aflatoxin distinguishing method, which comprises the following steps of: detecting values of certain chemical constituents in stored food in real time within a detection period by adopting a conventional instrument, so as to obtain related information of the quality change of the stored food and the real-time process of the change of aflatoxin B1 according to the values, dividing the change process of the aflatoxin B1 into a plurality of levels by taking the change trend and the change degree of the quantitative values of the chemical constituents as the distinguishing basis, determining early-warning indexes according to the levels, sending early-warning signals of the stored food, and regulating and controlling a storage environment and storage conditions in real time. According to the method, the early-warning signals are sent according to the real-time change of the related chemical constituents, the food storage environment and the food storage conditions are regulated in time at the early stage of generation of the aflatoxin, the safety of the stored food is guaranteed, and the loss caused by poisons generated by mildew is reduced. The method has the advantages of being simple, high in operability, and capable of detecting in real time, visual in judgment and timely in early warning.
