Abstract
Six formulae (formula 1 - 6) of corn beverages were prepared from sweet corn kernel and cob water extract in the ratio of 1:3, 1:5, 1:7, 1:9, 1:11, and 1:13 by weight, respectively and the cane sugar was added in each formula of corn beverage to improve the taste (total soluble solid of each sample was 13? Brix) and made into canned corn beverage (20 oz lacquer can). It was shown that canned corn beverage formula 1, 2, and 3 were accepted by taste panelists in term of color, flavor, texture and acceptability compared with the rest of samples (p < 0.05). The accepted sample formula 3 was made in to canned corn-milk beverage (20 oz lacquer can) formula 7 - 11 by adding 2, 4, 6, 8, and 10% by weight of whole milk powder, respectively and the cane sugar was added in each formula to improve the taste (total soluble solid of each sample was 13? Brix). It was found that canned corn-milk beverage formula 7, 8, and 9 were preferred by the taste panelists when compared to the others (p < 0.05). The processing time at 121.1? C or 250? F (initial temperature at 65? C or 149? F) of the corn beverage formula 3 packed in lacquer can size 5.5 oz, 15.0 oz, and 20.0 oz were 15, 20, and 20 minutes with Fo value of 6.7, 7.2, and 6.6 minutes, respectively, while that of cornmilk beverage formula 8 were 15, 20, and 20 minutes with Fo value of 6.1, 6.7, and 5.9 minutes, respectively. The protein and fat contents of canned corn-milk beverage formula 8 were 9.30 and 1.10% on dried weight basis while that of canned corn beverage formula 3 were only 3.22 and 0.14% on dried weight basis, respectively. The vitamin A, B1, B2, and niacin content of the accepted canned corn-milk beverage formula 8 were increased in the range of 1.09 - 1.81 times and the vitamin C and inositol were reduced to 0.82 and 0.89 time, respectively. The calcium, phosphorus, potassium, and iron were increased in the range of 1.84 - 10.80 times when compared to the canned corn beverage formula 3. The protein quality of the accepted canned corn-milk beverage formula 8 showed higher chemical score of lysine and tryptophan at 113 and 140% as compared to 53 and 60% of the canned corn beverage formula 3.
