Method for preparing high-temperature resistant essence microcapsules

The invention discloses a method for preparing high-temperature resistant essence microcapsules, which comprises the following steps: preparing aqueous solution of gelatin and aqueous solution of Arabic gum by gelatin and Arabic gum respectively, then adding oil-soluble essence into the aqueous solution of Arabic gum and performing homogenization and emulsification on the solution, and uniformly mixing the emulsified solution and the aqueous solution of gelatin to obtain emulsified liquid; adjusting the pH of the emulsified liquid to 4.15-4.17 by using edible acetic acid; dissolving a curing agent glutamine transaminase in water, and then mixing solution of the curing agent and the emulsified liquid to perform curing; filtering the cured emulsified liquid, discarding the supernate, and collecting the sediment; dissolving a wall material obtained by mixing Arabic gum, malt dextrin, glucose and isolated soy protein in the water, then adding the collected sediment into the solution of wall material to be uniformly mixed, and preparing the mixture into the high-temperature resistant essence microcapsules by adopting a spray drying method. The method prepares the oil-soluble essence into the microcapsules so as to keep the primary fragrance of the essence and ensure the using effect in high-temperature processing.

Nonaqueous electrolyte secondary battery

Disclosed is a nonaqueous electrolyte secondary battery wherein the energy density is improved by increasing the range of depth of discharge to be used. Specifically disclosed is a lithium ion secondary battery 20 wherein an electrode group 6 is contained within a battery case 7. The electrode group 6 is formed by winding a positive electrode plate W1 and a negative electrode plate W3 with a separator W5 interposed therebetween. The positive electrode plate W1 has positive-electrode mixture layers W2 which are formed on both surfaces of an aluminum foil and contain a positive-electrode active material. The positive-electrode active material contains lithium iron phosphate as a principal component. The negative electrode plate W3 has negative-electrode mixture layers W4 which are formed on both surfaces of a rolled copper foil and contain a negative-electrode active material. The negative-electrode active material contains a mixture of a graphite material as a principal component and an amorphous carbon material as a secondary component. The positive electrode plate W1 has a positive-electrode initial charge/discharge efficiency of e1, the negative electrode plate W3 has a negative-electrode initial charge/discharge efficiency of e2, and e1 and e2 satisfy the relation of formula e2=e1−x (10≦x≦20). This avoids usage of the high resistance region of the positive electrode plate W1.
