Abstract:
A method is provided to extract high quality DNA stably by decomposing gelatinized starch of boiled rice, thereby being utilized to identify varieties of the rice during distribution and consumption steps. A method for identifying rice varieties comprises the steps of: (a) decomposing boiled rice obtained by gelatinizing rice with heat-resistant alpha-amylase in a 2% CTAB(cetyltrimethylammonium bromide) buffer solution to extract DNA therefrom; (b) amplifying the extracted DNA through PCR using at least one SSR primer selected from the group consisting of an OSR20 primer consisting of SEQ ID : NOs. 1 and 2, an RM240 primer consisting of SEQ ID : NOs. 3 and 4; and an RM257 primer consisting of SEQ ID : NOs. 5 and 6; and (c) identifying variety from the PCR product through DNA finger printing.

Abstract:
PURPOSE: An instant tea product made from powdered kyoungokko, a kind of Korean traditional restorative, glucose, ginseng flavor and lactic acid is provided to promote metabolism and reactivity of body by the kyoungokko ingredient. CONSTITUTION: The instant tea is prepared by the steps of: (i) making kyoungokko by compounding 52.6wt% of Rehmanniae Radix juice, 5.3wt% of ginseng powder, 10.5w% of powdered hoelen and 31.6wt% of honey in a stainless container and aging by heating the mixture in a water bath of 70-80deg.C for 5days; (ii) boiling the blackish brown viscous kyoungokko with 2times of water for 10min and getting a solution of kyoungokko by compressing the boiled kyoungokko in a sack; (iii) freezing the resulting solution at -60 to -70deg.C for a day and drying the frozen solution in a vacuum drier under a condition of 30-40deg.C and 90-110mmHg; and then (iv) mixing 30wt% of the lyophilized kyoungokko powder with 66-66.7wt% of glucose, 0.1-3.0wt% of ginseng flavor and 2.9-3.0wt% of lactic acid. The tea composition of kyoungokko is then melted in hot water to be taken.

본 발명은 보리, 호밀, 귀리와 같은 곡물류로부터 천연식이섬유이며 생리활성물질인 β-글루칸을 추출하는 방법에 관한 것으로, β-글루칸을 함유한 곡물분말을 가수(加水) 용해시켜 β-글루칸을 추출하고 불순물을 제거한 후 주정 또는 알코올류를 이용하여 분리농축하여, 쌀보리의 경우 100g당 순도 80∼90%의 β-글루칸을 약 3∼4g정도 수득할 수 있는 특징이 있다.
Abstract:
PURPOSE: Provided is a method for simply extracting beta-glucan from grains at high yields. CONSTITUTION: The method for extracting beta-glucan comprises the steps of: grinding grains containing beta-glucan such as barley, rye or oats; adding hot water into the grain powder; agitating the grain mixture for 1 to 2 hours and centrifuging it; collecting the supernatant therefrom and heating it at 60 to 100 deg. C to deactivate beta-glucanase and coagulate proteins; adding alpha-amylase into the solution and cooling it; filtering the solution to remove coagulated proteins; adding alcohol into the filtrate and slowly agitating the solution to precipitate solid components; and centrifuging the solution and removing the supernatant to collect the solid beta-glucan.
Abstract:
PURPOSE: A precooling apparatus capable of shortening a precooling time is provided which reduces labor power and consumption energy for the precooling process and preserves high quality vegetables or fruits for a long period of time. CONSTITUTION: In a tunnel type precooling apparatus, an inlet door(1) and outlet door, which are slid, opened and closed up and downwardly, are installed on both sides of a precooling chamber(3), a transfer conveyor(3a) for transferring each precooling product is installed in plural rows inside the inlet and outlet door and at the interior of the precooling chamber. A cold air through-hole(8a) also is formed at the interior of the cooling chamber to cause the circulation of cold air between the upper and lower space. A differential pressure fan(4) for forcibly circulating cold air is arranged on both sides of the transfer conveyor. A unit cooler(5) forcibly circulating cold air and generating cold air is arranged at the lower part of the transfer conveyor.
