White bread has a short shelf life thus the loses its desired charcteracteristics upon storage and its also subject to spoilage by fungi. To avoid this spoilage and increase shelf life the addition of different levels of acidulants (calcium propionate acetic acid and sorbic acid at 0.1 0.2 and 0.3%) were evaluated for their quality characteristics contributing with acidulants as well as their microbial shelf life during 12 days of storage. In addition the mathematical model (GAB and BET) were applied to study the storage condition of bread. From the experiment it was found that bread with calcium propionate addition had the highest specific volume and springiness followed by bread with acetic acid and sorbic acid adding. On the other hand bread contained sorbic acid had the highest density hardness chewiness and color values (L* a*b*) followed by acetic acid and calcium propionate addition in order. Bread contained calcium propionate had the longest shelf life (12 days) followed by bread with acetic acid (8 days) and sorbic acid (6 days) adding respectively. The increase in acidulants levels result in an increase of bread shelf life. From the sorption isotherm curves bread contained 0.3% calcium propionate had the highest monolayer moisture content indicating that it was the most effective against microbrial spoilage of white bread studied.

Food for children from broken to lose the wheat was in frozen chocolate cake from jasmine rice flour and substitute of yolk by mucilage of Basil seeds The study of chilled Mucilage. It was foundthat the tasting testers rated the preference in the formulation using freeze-thawed grapefruit seed for 2 days and then studied the physical qualities. Texture there was a statistically significant difference (p≤0.05) Product image it was found that the tasting testers rated their preference at 650 watts maximum temperature and then studied the physical qualities.of the texture quality. There was a statistically significant difference (p≤0.05) and chemical quality analysis. Moisture protein fat ash coarse fiber and carbohydrate content And fiber content More than market products Consumers accept the product of frozen chocolate cake from Jasmine Rice Flour and substitute Egg Yolk with Basil Musk Seed up to 99%. Flour crepes broken rice from Riceberry Add the rice Rice berry crepes deduct 50 percent broken rice from Rice berries are brighter and more reduced. Since Rice Rice berries are dark purple broken. Crepes made from rice Rice Rice Rice used Danbury Danbury deduct 100 percent brightness is reduced. Part of the red crepe of rice and broken rice berries increased statistically significantly (P≤0.05) possibly due to broken rice Rice berries are dark purple. Crepes rice broken rice with red berries that last weekend. The rice Rice Berry deduct 100 percent of the volume of baking products crepes of rice and broken rice 3: 1 1.5 and 2 percent by weight the color of Waterloo activity. The crepes of rice and broken rice berries. The color brightness (l *) and the water activity. The difference was statistically significant (P≤0.05) with crepes rice broken rice baking berries on volume increased from 1.5 to 2% of tests consumers found that consumers are women the highest percentage. 72 percent of consumers admit to produce only 74 percent Cream filling from broken rice The quality of the fiber Mucilage from Basil Seed from fresh and dry. not different Rate of soluble fiber from Mucilage from Basil Seed dry with moisture. with humidity ≤10% and aw not exceeding 0.6 packed in bags foil dose of 5 g as a physically similar to polyester Milliken Lake. e live in an amount of 20 g ratio of 1.7 the ratio of flour rice Berry: corn starch cream filling from broken rice mites Berry level (percentage) 100 0 panelists to rate the passion in every aspect of it. the best Thus the comparison of the physical and chemical qualities of rice with cream filling was broken spokes berries.

This research aims to study the base formulation of Pad Thai noodle to study on type and quantity of modified starch in Instant Pad-Thai noodle. To study on the amount of Pad Thai sauce to supplement in Pad Thai noodle. To study on the quality of Instant Pad Thai noodle with Pad Thai source to design the optimal packaging for Instant Pad Thai noodle and to study of consumers acceptance of Instant Pad-Thai noodle with Pad Thai source. The results of this study showed that the optimal formula of Pad Thai noodle was 80 grams of rice starch 100 grams of tapioca and 300 grams of water. The color values of L * (brightness) a * (red) and b * (Yellow) was 64.13 ± 0.01 -0.92 ± 0.02 and 14.52 ± 0.02 respectively. This Pad-Thai noodle has a slightly yellowish white color with a moisture content of 5.31 ± 0.03 %. The optimum amount of modified starch used in the semi-finished fried Thai noodle formula by replacing the tapioca starch in the basic formula was modified starch 30 per 70 grams of tapioca starch. The modified formula of Pad Thai noodle has a slightly yellowish white color with L * (brightness) a * (red) and b * (yellow) equal to 62.82 ± 0.01 -1.10 ± 0.01 13.45 ± 0.01 respectively with a moisture content of 5.66 ± 0.11 %. The amount of Thai stir-fried sauce used in the semi-finished fried Thai noodle recipe by replacing the amount of water in the recipe was 80 grams of rice flour 70 grams of tapioca flour 30 grams of modified flour and 100 grams of Thai stir-fried sauce and 200 grams of water. The color of modified Pad-Thai noodle was L * (brightness) a * (red) and b * (yellow) equal to 43.67 ± 0.01 8.25 ± 0.02 and 22.42 ± 0.10 respectively with moisture content of 2.58 ± 1.36 %. The number of microorganisms was less than 10 CFU/g. The amount of yeast and mold was less than 10 CFU/g and E. coli content was less than 3 MPN /g. Semi-finished Thai stir-fried noodles with sauce were slightly brownish. The noodle was soft and sticky and had the smell of Pad Thai sauce. There was a taste of Thai stir-fried sauce added in the Pad Thai noodle was tear more difficult than the other commercial noodle.
