加工トマトに関する研究(第5報) : San Marzano種3系統の加工適性試験

(1) Three strains of San Marzano variety of tomato(SM1, SM2, SM3) were qualified of the suitability for manufacturing, evaluating as follows.
Yield of raw pulp of tomato ; total solids of raw pulp ; sp.gr., total solids, total acidity, pH, and sugar content of the filtrate of raw pulp ; yield of tomato puree ;
harvest of raw pulp and of tomato puree per unit area of farm field.
(2) Strains SM3 and SM2 were excellent in puree yield per raw pulp.
(3) SM3 was most excellent, SM2 was excellent and SM1 was fairly good in colour quality of puree.
(4) There was almost no difference between the three strains in the other points examined.
(5) It was observed that the high yields of puree per fruits of these strains were not due to the puree yield per raw pulp but based on the high yield of raw pulp per fruits.
(6) SM3 was excellent strain in the quality of puree produced, while SM1 was superior in puree yield per uint area of farm field.
