The present invention relates to a method for preparing additive-free and unadjusted soy milk using fine powder of raw soybeans, and additive-free soy milk prepared thereby. In detail, the present invention provides a method for preparing additive-free and unadjusted soy milk that contains no artificial additives, and additive-free soy milk prepared thereby, the method comprising the steps of: carefully sorting and selecting only raw soybeans in a good condition obtaining fine powder of the raw soybeans through dry milling obtaining nano wave water through special treatment stirring and uniformly mixing the nano wave water and the fine powder of the raw soybeans heating and maturing the resultant mixture at the boiling temperature of water packing the mixture into an appropriate container and finally sterilizing the mixture. The additive-free soy milk according to the present invention uses the overall raw materials as they are without any loss of the raw materials such as a soybean curd residue among the raw materials of the soybean, and therefore there is no loss in nutritional contents. Also, since soy milk is prepared only with a bean (soybean) and water without addition of various artificial additives for providing a chewy texture, there is no toxic ingredient to the human body. Furthermore, since the fresh smell and the fishy taste of the bean (soybean) are removed through special treatment, the soy milk tastes good and is excellent in flavor. Accordingly, the soy milk is healthy food that can be safely taken without causing resistance to additives.본 발명은 생대두 미세분말을 이용한 무첨가 무조정 두유의 제조 방법 및 이에 의해 제조되는 무첨가 두유에 관한 것으로서, 구체적으로는 양호한 상태의 대두만을 엄선하여 선별하고, 건식 분쇄법에 의해 생대두 미세분말을 얻고, 특수 처리하여 나노 파동수를 얻은 후, 상기 나노 파동수와 생대두 미세분말을 교반하여 균일하게 혼합하고, 상기와 같이 얻어진 혼합물을 물의 비등 온도에서 가열 및 숙성하고, 적당 용기에 포장하고 최종적으로 살균 처리함에 의해 인공 첨가물이 전혀 포함되지 않은 무첨가 무조정 두유를 제조하는 방법 및 이에 의해 제조되는 무첨가 두유를 제공한다. 본 발명에 따른 방법에 의해 제조되는 무첨가 두유는 대두 원료 중에서 비지와 같은 손실이 없이 원료 전체를 그대로 사용하므로 영양성분의 손실이 없고, 식감을 내기 위한 각종 인공 첨가제
