Abstract: A preparation method of a walnut yogurt includes roasting peeled walnut kernels at 145° C. to 165° C. for 5 to 25 min, degreasing the roasted walnut kernels until the fat content is 20% to 50% to obtain semi-degreased walnut kernels, mixing the semi-degreased walnut kernels with a stabilizer, a carbon source and water and then milling the resultant to obtain a walnut slurry, and subjecting the walnut slurry to fully mixing, sterilization, inoculation, and fermentation to obtain the walnut yogurt. This preparation method can effectively improve the aroma of walnuts after roasting at high temperature. On this basis, the ideal flavor of the system can be ensured after removing part of the fat. Moreover, a yogurt with stable quality and rich nutritional value can be obtained by removing fat to the above degree.

Abstract: An RF antenna system is provided for mounting on a window of a vehicle comprising exterior and interior window mountable portions. The first and second portions include an RF coupling section (4) to inductively couple an RF signal received from antenna (20) and a power coupling section (6) for providing external power to an external amplification portion 52 for amplifying received RF signals. The system includes a further electrical connection (16) to a metallic shim (18) which is magnetically fixed to the roof of the vehicle and electrically connected thereto, whereby the roof provides a ground plane for the antenna, by capacitive coupling of the metallic shim to the vehicle roof.
