Abstract

|
|
From the previous studies, F-P-4 formula was found to be comparable to full fat dry milk in its nutritive value and feeding performance. However, an attempt was made in order to make sure whether or not any possibility might exist, by which further improvement of nutritive quality and simultaneous reduction of product costs may be achieved Using F-P-4 as a control, modifications were made in new formulas, F-P-5, F-P-6 and F-P-7 by reducing FPC,´eliminating yeast from the mixture, and by enriching with methionine as needed In particular, F-P-7 is completely free of FPC, hydrogenated oil and yeast. Yet, levels of total protein and fat were kept equal to those of F-P-4 in all formulas.
An animal feeding test for all formulas using 10 female rats per group for 8 weeks and an infant feeding trial for F-P-5 and F-P-5 with 5 of each female infants under age of one for one month were conducted along with F-P-4 as a control. Almost the same results were obtained with F-P-4, 5 and 6, but F-P-7 showed the lowest body weight gain. FER of F-P-5 and 6 was 0.20 as was with F-P-4, while that of F-P- 7 was 0. 16. Acceptability to infants was excellent; growth, appearance and biochemical data were normal.
As an example F-P-4 packed in 0.04 mm polyethylene bags was used for storage study at 25C and relative humidity of 65^800lo for 8 months. Although viable bacterial counts and vitamin C contents were reduced, peroxide and TBA values were increased gradually during such storage. Since there are also significant changes in color and organoleptic quality, the expected shelf life:
under the given conditions is considered to be about 2 months and thus further works are needed both on the product and packaging in order to improve the storage stability.
Either elimination of yeast form F-P-4, that is F-P-S, or partial replacement of FPC with methionine, that is F-P-6 may well reduce meterial costs about 10,00. Considering blending process of ingredients, F-P-5 is thus found to be the best formula developed. While F-P-7 free of FPC is inferior in its nutritive quality than that of others, but significantly superior than of rice. Further-more, the material cost of the product can be reduced about 20190 from that of F-P-4. And thus this vegetable blend is considered to be useful as a low cost supplementary food mixture for growing children.
