The invention provides a manufacturing method of frozen microwave ready to eat (silvery hair group, chronic sick friend) food, which is mainly that the food materials must be shaped (general shape or broken, finely broken, muddy) and impregnated before cooking and boiling, and the impregnated solution is an aqueous solution (which can be polysaccharide, colloid, phospholipid, starch, polyemulsion) with a concentration of 3% - 15% trehalose and 0.1% - 10% food thickener Acid, food tackifier or food adhesive).Trehalose and food thickener are used to cover the food materials to form a film, so as to increase the water retention, slow down the escape, stabilize the structure of the food materials, inhibit starch aging, protein denaturation, oil rancidity, unsaturated fatty acid decomposition, browning of fruits and vegetables, and protect the tissues, so as to strengthen the water conservation of the frozen food materials and improve the dry taste.本發明係提供一種冷凍微波即食（銀髮族、慢性病友）食品製造方法，主要係食材於烹飪煮熟前須整形（一般形狀或破碎、細碎、泥狀）浸漬，其浸漬溶液，係以濃度３％－１５％之海藻糖和0.1％－10％食品促稠劑的水溶液(可為多醣體、膠質、磷脂質、澱粉、聚乳酸、食品用增粘劑或食品用接著劑)。利用海藻糖與食品促稠劑包覆食材，形成被膜，以增加保水度，減緩逸散，並穩定食材結構，抑制澱粉老化、抑制蛋白質變性、抑制油脂酸敗、抑制魚肉加熱時不飽和脂肪酸分解、抑制蔬果褐變、保護組織，藉以加強冷凍調理食材保水，並改善口感乾澀。
