واردات دانه روغنی کنجد سفید درجه یک

انسان به خواص معجزه آسای روغن کنجد متجاوز از پنج هزار ساله که پی برده است. امروزه نیاز روز افزون بشر باعث واردات دانه های روغنی کنجد شده. کنجد سفید درجه یک بیشتر از پاکستان وارد بازار ایران می گردد.
روغن کنجد یکی از روغن های اشباع نشده و مفید برای بدن است. که در آمریکای شمالی و کانادا به مقدار زیاد مصرف می شود. زیرا این روغن نه تنها کلسترول را افزایش نمی دهد، بلکه آن را کاهش نیز می دهد.
درصد روغن گیری 45 الی 50 است روغن شفاف، زرد ولی شیرین زیاد نیست. در شمال کشورمان کشت می شود و به دو حالت با پوست، بدون پوست در بازار وجود دارد. کنجد منبع خوب کلسیم هست. کمبود کلسیم برابر کم خونی می باشد از این رو برای درمان کم خونی نیز موثر می باشد. روغن کنجد بهترین روغن برای سرخ کردن در بین روغن ها است و گرفتگی صدا را بر طرف می کند.

/**
 * Meta API: WP_Metadata_Lazyloader class

/**
 * Core class used for lazy-loading object metadata.
 *
 * When loading many objects of a given type, such as posts in a WP_Query loop, it often makes
 * sense to prime various metadata caches at the beginning of the loop. This means fetching all
 * relevant metadata with a single database query, a technique that has the potential to improve
 * performance dramatically in some cases.
 *
 * In cases where the given metadata may not even be used in the loop, we can improve performance
 * even more by only priming the metadata cache for affected items the first time a piece of metadata
 * is requested - ie, by lazy-loading it. So, for example, comment meta may not be loaded into the
 * cache in the comments section of a post until the first time get_comment_meta() is called in the
 * context of the comment loop.
 *
 * WP uses the WP_Metadata_Lazyloader class to queue objects for metadata cache priming. The class
 * then detects the relevant get_*_meta() function call, and queries the metadata of all queued objects.
 *
 * Do not access this class directly. Use the wp_metadata_lazyloader() function.
 *
