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.

To transfer technology to develop potential food products for the elderly from the leftovers after harvesting of the farmer group. Saraburi province towards sustainable commercialization In the study of consumer acceptance of fat-substituted buttercakes it was found that the appearance aspect was most satisfied. Accounted for 44 percent. Colors were the most satisfied. Accounted for 53 percent. Flavor (butter) was the most satisfied. Accounted for 58 percent. Flavor (butter) was the most satisfied. 46 percent of the taste was the most satisfied. Accounted for 58 percent. The texture (softness) was the most satisfied. They accounted for 53 percent and overall liking was the most satisfied. Representing 55 percent of Vietnamese pork products Can add boiled sweet parsnips at 4 percent with the most liking scores. Physical quality Has a texture has a good fit is not harsh Flexible Chemical quality was found to have protein content. Coarse fiber content than other products on the market. It can be stored in a vacuum PE plastic bag at 4-7 degrees Celsius for 15 days. Able to add fresh sweet pea at 2%. The panelists rated the taste the most. Physical quality Found to be the most crispy when using microwave technology And chemical quality was found to have more coarse fiber content. And has a lower amount of fat carbohydrate and energy than other products in the market It can be stored by packing in a zip lock foil bag. And seal the bag for a period of 25 days. Consumers accept the product. Which is good for the health of consumersdegrees Celsius. It was found that the shelf life was 6 days along with 49% of consumers who liked it very much bought 81% of the product and accepted 89% of the product. Type 4 Red Curry Pa Wan Pa Roasted Chicken Breast Method 1 Boiled Brine 1 The method was the most suitable method for preparing wild sweet berry leaves with a pH of 5.07oBrix value at 9.90oBrix salt value at 7.70. The panelists rated a moderate preference. And to study the changes between the storage of products of red curry leaves Pak Wan Pa grilled chicken breast Keep at temperature.
