Abstract:
A method of cultivating paddy field plants for advertizing in summer seasons is provided to make characters using various different colored paddy field plants, thereby using the paddy field plants for advertising. A method of cultivating paddy field plants for advertizing comprises the following steps of: planting colored rice(110) in a first space where an advertising message is shown; planting green rice in a background space(120); and planting the colored rice in the circumference of the first space. The colored rice represents purple rice whose leaf and stem are purple. The method of cultivating paddy field plants for advertizing in winter seasons comprises the following steps of: planting landscape plants in the first space; planting winter cereals plant in the background space; and re-planting the landscape plants in the circumference of the first space.
Abstract:
색상및 열안정성이향상된수수천연색소의제조방법, 수수천연색소추출물에아세트알데하이드를처리하는단계를포함하는천연색소의안정화방법및 상기천연색소를플라스틱성형재료에혼합하여플라스틱성형물을제조하는단계를포함하는천연색소로착색된플라스틱성형물의제조방법에관한것이다. 수수로부터천연색소추출물을추출한후, 이를아세트알데하이드와축합반응하여색상및 열안정성이향상된고분자화된천연색소를제조하였으며, 이를플라스틱과혼합하여, 색상안정성이향상된플라스틱을제조할수 있다. 따라서, 이러한방법에의해생산된플라스틱을이용하여천연색소를함유한인체친화적이고위생적인제품을개발할수 있다.
Abstract:
본발명은 (a) 수수()의부산물로부터유래된천연색소추출물을금속염이포함된용액으로처리하여상기색소추출물을안정화시키는단계; 및 (b) 상기안정화된색소추출물을플라스틱성형재료에혼합하여플라스틱성형물을제조하는단계를포함하는, 안정성이향상된색소추출물로착색된플라스틱성형물의제조방법에관한것으로, 수수부산물유래의천연색소추출물을금속염으로킬레이션한후, 이를이용하여플라스틱성형물을제조한경우, 일광견뢰도가향상되었고, 색상안정도가우수하였다. 따라서, 이에의해생산된플라스틱을이용하여천연색소를함유한인체친화적이고위생적인제품을개발할수 있다. 특히, 본발명은수수에서추출한색소로착색된플라스틱사출물제조를위한최적가공법을제공함에있어, 천연색소의문제점인일광에대한낮은안정도를높이기위해금속염과의최적가공조건을확립함으로써천연색소로착색된제품의완성도를높일수 있다.
