The invention discloses a method and a device for searching an interest point. The method comprises the following steps: obtaining position information provided by mobile equipment, receiving and recording a search request, wherein the position information comprises a direction corresponding to the mobile equipment and the search request comprises at least one screening condition; searching and recording the interest point meeting the search request as a first search result set; calculating directional included angles of search results corresponding to the position of the mobile equipment in the first search result set, removing the search results with the directional included angles of more than an angle threshold value, and recording the rest search results as a second search result set; and outputting and displaying the second search result set. The device comprises a position and information obtaining module, a search module, an angle calculation and screening module and an outputting and displaying module. According to the method and the device, the interest point can be dynamically adjusted according to the change of the orientation of the mobile equipment by utilizing an electronic compass function of the mobile equipment.

The invention discloses a degradable bacteriostatic food packing material and a preparation method thereof. The preparation method comprises the following steps: irradiating chitosan by a radiation method for degradation; adding coupling agent aid solution into the degraded chitosan, mixing and stirring; drying the mixture to remove the solvent and then adding a degradable polymer material and mixing; and adding lubricant and plasticizer and finally preparing a film product. The invention adopts chitosan as an antibacterial raw material. The chitosan has high antibacterial activity and can suppress the growth and breeding of certain fungi, bacteria and viruses; and a small amount of the chitosan is used, and the toxic side effect is avoided; polylactic acid and polycaprolactone can be degraded completely, and the film forming performance and the processability are high; the film material prepared by combining the chitosan is used as bacteriostatic preservative material, and compared with the common packing material, has good bacteriostatic effect and strong preservation power and can prolong the shelf life of the food; moreover, the bacteriostatic long-term effectiveness of the bacteriostatic plastic can be synchronized with the service life of the product, thus being convenient and economic; and after the using period, the bacteriostatic plastic can be either recycled or degraded and assimilated with the nature without causing environmental pollution.

The invention discloses a hawthorn essence and a preparation method thereof. The hawthorn essence comprises the raw materials by weight percent: 10.0-20.0% of hawthorn extract, 0.3-1.0% of eugenol, 0.05-0.2% of lemon oil, 0.1-0.3% of geraniol, 0.1-0.5% of hexenyl acetate, 1.0-2.0% of 2-methyl butyric acid, 0.1-0.5% of strawberry acid, 0.1-0.3% of acetic acid, 0.5-1.0% of ethyl acetate, 0.5-1.0% of ethyl butyrate, 0.1-0.5% of isoamyl acetate, 0.1-0.3% of trans-2-hexene aldehyde, 0.05-0.2% of furanone and the balance of propylene glycol. The hawthorn essence provided by the invention has natural hawthorn fragrance and taste, is high in natural feel and fresh feel, and is mild and lasting in fragrance.

The invention discloses an orange water essence, formed by 1% butyl acetate at 0.18-0.26, 1% aldehyde group NO. 3 at 0.08-0.15, 1% alcohol at 0.01-0.02, 1% 3-hydroxy ethyl caproate at 0.015-0.023, 1% reverse-2-hexenol at 0.020-0.035, 1% ethyl caproate at 0.008-0.012, 1% fragrance at 0.016-0.025, 1% citral at 0.03-0.07, and the left is 10% orange oil. The invention can avoid the defects of presentorange soluble essence as easy volatile and bad orange simulation, with natural feeling.
