| Research Abstract |
TOESTABLISH PALATABILITY ESTIMATION FORMULA OF COOKED RICE, THE MESUREMENT OF PHYSICOCHEMICAL PROPERTIES OF RICE AND THE SENSORY TEST OF COOKED RICE WERE CARRIED OUT. EXPERIMENTAL SAMPLES WERE 19 VARIETIES IN 1984, 21 IN 1985 AND 31 IN 1986.
OF THE PHYSICOCHEMICAL PROPERTIES, BROKEN RICE RATIO (M), VOLUME OF COOKED RICE (P), IODINE BLUE VALUE (N), STICKINESS (S) AND ADHESIVENESS (R) WERE FOUND TO HAVE THE CLOSE RELATION WITH SENSORY EVALUATION (TO) BY LEAST SQUARES METHOD USING THE ABOVE-MENTIONED PROPERTIES AS THE INDEPENDENT VARIABLES AND TO AS THE DEPENDENT VARIABLE.
F-1 Tt = a M + b p + c N + d R + e S
F-2 Tt = a'M + b'P + c'N + d'R + e'S + f'
THE SAMPLES WERE DIVIDED INTO 7 GROUPS ACCORDING TO THE PRODUCTION YEAR AND AREA. FOR THE TWO FORMULAS, 7 EQUATIONS WERE MADE WITH THE GROUPS' DATA. WE TRIDE TO APPLY ONE EQUATION FOR EACH GROUP. THE DEGREE OF ITS APPLICABILITY WAS JUDGED FROM THE SIGNIFICANCE OF CORRELATION BETWEEN TT IN THE FORMULAS AND TO IN SENSORY EVALUATION.
AS THE RESULT, F-2 WAS FOUND TO HAVE MORE APPLICABILITY THAN F-1, BECAUSE 4 EQUATIONS SHOWED SIGNIFICANT CORRELATION IN 5 OR 6 OF THE 7 GROUPS.
AS FOR THE APPLICABILITY OF F-2,IN REGARD TO THE SAME GROUPS THAT THE EQUATIONS WERE PREPARED FOR, THE CORRELATION COEFFICIENTS WERE 0.75-0.94 AND ALL WERE SIGNIFICANT AT THE 1% OR LESS LEVEL. IN REGARD TO THE OTHER GROUPS, THE EQUATION WHICH WAS MADE FOR 31 VARIETIES IN 1986 SHOWED THE MOST APPLICABILITY, THE CORRELATION COEFFICIENTS WERE 0.21-0.85, AND ALL WERE SIGNIFICANT AT THE 5% OR LESS LEVEL.
THE MOST DESIRABLE EQUATION WE HAVE GOT WAS AS FOLLOWS.
Tt =-0.040M+0.030P+0.179N+1.427R-0.121S-1.261
