Firstly, what is the difference between jujube seed and sour jujube seed? Pure sour jujube kernel key produced in the northern region. In which, in the northern region of the sour jujube kernel, especially in order to the foothills of the Taihang mountain area production of the sour jujube kernel quality for high quality. But sour jujube kernel one season a year, after the fall season harvest perfect fruit, greatly limited the production of sour jujube kernel. As a result, the price of sour jujube kernels is rising, and on the sales market, poor stores are replacing sour jujube kernels with imitations of Rizaoren and Hovenia dulcis. Pure sour jujube kernels are flat round or flat oval, with a width of five to nine millimeters, and a thickness of about three millimeters; the color of the kernel is mostly dominated by dark purple and purple-brown, and the surface looks very shiny and glossy. The seed coat of pure jujube kernel is brittle and easy to crush. After scratching the seed coat, query the endosperm we can see that the endosperm of the sour jujube kernel is milky white, and the flavor is light.
Secondly, the counterfeit sour jujube kernel is dominated by Li Zao Ren, the volume is significantly smaller, the thickness is generally less than three mm. the color tone of the surface layer is also significantly different, mostly reddish brown, black brown or greenish dark brown. And Li Zao Ren's seed coat is too hard, endosperm flavor slightly astringent, that kind of sour jujube kernel is attributed to imitation of oh, is not much efficacy and effect, and the price is very much cheaper, we all need to pay attention to the choice of sour jujube kernel, must distinguish between the real sour jujube kernel, don't have to be cheated by fooling oh.
See here, I think we have long understood, sour dates have a very significant look, so for us is better to distinguish, if we can more time, then there is no doubt that will allow us to distinguish between high-quality sour dates, looking forward to everyone is helpful.
