The objectives of this research were to study the effect of hot air velocity on the changes of the moisture content and temperature of preserved tomatoes undergoing combined conveyor system and hot air drying. Specific energy consumption physical properties in term of color and shrinkage and sensory evaluation of dried preserved tomatoes were also investigated. The preserved cherry tomatoes were dried at a drying temperature of 80oc and hot air velocity of 2 and 4 m/s until the moisture contents of the preserved tomatoes were lower than 18% wet basis. The experimental results showed that the hot air velocity had effect on the changes of the moisture content and temperature of preserved tomatoes. Specific energy consumption total color difference shrinkage percentage and sensory evaluation results of dried preserved tomatoes of the hot air velocity of 2 and 4 m/s were not significantly different (P>0.05).Moreover the dried preserved tomatoes obtained from this research had significantly lower sensory scores in term of color and appearance than those obtained from the local market (P≤0.05). However sensory scores in term of flavor texture and overall preference of the dried preserved tomatoes obtained from this research and the local market were not significantly different (P>0.05).

The purpose of this thesis is to design and develop packaging for educational products and to develop packaging products from processed Queen tomatoes from the Don Tum Subdistrict Community Enterprise. Nakhon Pathom To create identity for the product and to achieve the efficiency of the packaging for processed Queen tomato products from the Queen of Don Tum Subdistrict Community Enterprise Objectives 1. To design and develop the packaging structure. 2. To design the graphic packaging to be consistent with the organizations identity as well as to communicate clearly to the consumer. 3. To design the product display with the product that has developed the packaging. There are different forms of structure and graphics that do not go in the same direction therefore designing the packaging to be interconnected through the form of graphics and structures. By selecting the processed agricultural products from Queen Tomato of Don Tum Subdistrict Community Enterprise Nakhon Pathom Come to design 5 types namely fresh Queen tomato Dried tomato Fresh Queen tomato juice Queen Tomato Powder And tomato sauce for meat This step of the art thesis The researcher has interviewed entrepreneurs. Collect data to bring to the design development. By interviewing from experts in 3 aspects and preparing a satisfactory evaluation form for project design In order to study each type of design to produce the packaging model and collect statistical data for data analysis with the average percentage From the analysis of the efficiency of the study and development package of processed agricultural products from tomato Queen Of Don Tum Subdistrict Community Enterprise Nakhon Pathom Province Type A the results of the evaluation of packaging structure for processed agricultural products from Queen tomato of Don Tum Subdistrict Community Enterprise Nakhon Pathom province has an average of 4.75 which is in very good condition. Type B the graphic performance evaluation on the packaging for processed agricultural products from Queen tomato of Don Tum Subdistrict Community Enterprise Nakhon Pathom province has a mean value of 4.66 which is in very good condition. Type C The evaluation of the performance of exhibiting products for processed agricultural products from Queen tomato of Don Tum Subdistrict Community Enterprise Nakhon Pathom province the product has an average of 4.50 which is very good.

The purposes of this study were to study amount modified starch substitution by rice canned mackerel in tomato sauce seasoned with black pepper ratio at 15:85 20:80 and 25:75 percentage. The results showed that the best formulation of product was rice flour (percentage) 20:80 because sauce in can were red orange pH of sauce was = 6. The result of the study showed that the physical and chemical attributes of product canned mackerel in tomato sauce seasoned with black pepper compared with control. Found that canned mackerel in tomato sauce seasoned with black pepper of dark orange more than control. pH = 6.05 – 6.15 were similar moisture protein fat and carbohydrate content but the differences in ash content. The consumer acceptability indicated of target consumer accepted the product consumer need to buy this product 79% like moderately this product 72% and suitable price about 15 bath/can. The product of storage 6 mouths and not detects mesophilic aerobic bacteria and thermophilic aerobic bacteria.

This study aims to study the buying habits of tomato juice with students to study. Mixture Marketing Influencing consumer behavior to buy tomato juice of bachelor’s degree. To determine the relationship between the individual factors on the consumer behavior to buy tomato juice of bachelor’sdegree. And to compare the marketing mix Factors Influencing consumer behavior to buy tomato juice of bachelor’s degree 4 year coures faculty of home economics Technology Rajamangala University of Technology Phra Nakhon. By personal factors The sample of students 316 person The instrument was a questionnaire The statistics include freq percentage The mean standard deviation cost t-test F-test and Chi - Square (.𝑥2) The study indicated that Most consumers were female. 21 years The Year 4 Department of Food and Nutrition The average income per month. THB 5001-8000 Consumer behavior is found The most commonly purchased brand Doi Kham. The reason for the skin Intended to drink Bought formula 99-100% tetracaine-load pack (box) small (200 ml) at convenience stores / retailers. The study of factors that influence the buying habits of students drinking tomato juice with overall high level. The relationship between the individual factors on the consumer behavior to buy tomato juice of bachelor’s degree. Top Reasons to buy A sex relationships And year level The purpose of buying a sex relationships and the average income per month The type of tomato juice a popular buy. Correlated with the grade level and subject to the frequency of purchase. The size of the package purchased In relation to the subject The comparison factor influencing the buying habits of college students found that tomato juice with no gender influence the purchasing behavior of tomato juice. Products and influence the price level in both disciplines and the average income per month. The distribution of influence grade level. And the average income per month For the promotion influencing the level of the year.

The optimum formula for production of mayonnaise was developed with different on main ingredients (Formula 1; sweetened condensed milk and UHT milk formula 2; egg yolk formula 3; white egg). The effect of tomato lycopene added on physicochemical and sensory properties of mayonnaise was investigated. Physicochemical properties results on formula development were found that the formula 1 had the highest in TBA value and consistency. While formula 2 had the highest in total acidity a* and b* and formula 3 had the lowest in TBA a* and b* but the highest in L*. In addition sensory evaluations were not significant different (p > 0.05) between the 3 developed formulas. Thus the mayonnaise formula 1 was selected to investigate the effect of tomato lycopene levels (0 3 6 and 9%) on physicochemical properties. The results were found that lycopene content a* and b* increased with high level of tomato lycopene while the consistency value was decrease. Furthermore the levels of tomato lycopene were not effect on pH total acidity TBA and L*. Sensory evaluation revealed that the 6 and 9 % of tomato lycopene added had the highest on flavor. Thus mayonnaise supplemented with 6% of tomato lycopene was selected to study the storage at ambient temperature for 9 weeks. The results were found that total acidity TBA and consistency were not significant on during storage. However the pH TBA L* a* and b* was increase.
