The purpose of this study was to determine the optimal mixing condition of tomato powder and sugar for producing chiffon cake. The experiment was designed according to the central composite design of response surface, which yielded ten experimental points, including two replicates. Physiochemical and sensory properties were measured, and theses values applied to mechanical models. A canonical form and perturbation plot showed the influence of each ingredient on the final product mixture. The results of the physiochemical analysis of each sample showed significant differences in sweetness (P<0.01), color L (P<0.001), color a (P<0.001), color b (P<0.05), hardness (P<0.05), and cohesiveness (P<0.01). The sensory measurements were significantly different in color (P<0.05), appearance (P<0.05), flavor (P<0.05), sweetness (P<0.01), moistness (P<0.05), and overall acceptability (P<0.05). The optimal formulation, calculated using the numerical and graphical method, was determined to be 59.27 g tomato powder and 285.66 g sugar. The sensory evaluation showed significantly higher preferences in the color, flavor, appearance, texture, sweetness, tenderness, moistness and overall quality of the optimized chiffon cake compared to the controlled chiffon cake. The optimized chiffon cake also showed a high antioxidative activity compared to the controlled chiffon cake. Our results show that chiffon cake prepared with tomato powder enhances sensory characteristics and antioxidative activity.

The effects of differing baking ingredient formulations on physicochemical qualities and consumer preferences were investigated using sponge cakes incorporated with tomato powder, a healthy and beneficial food ingredient, as a model system. Tomato powder was incorporated into cake batter at four different amounts (0%, 10%, 20%, and 30%, w/w) by replacing equivalent amount of wheat flour. After appropriate mixing, sponge cakes were baked and cake quality attributes were evaluated after cooling. Specific volume decreased with an increase in the tomato powder substitution, although not significantly (p>0.05). On the other hand, baking loss increased from 10.3 (control) to 13.4 (30% sample) as the tomato powder level increased in the formulation. Lightness ($L^*$) decreased significantly from 79.5 to 74.1 whereas the firmness significantly increased with the higher incorporation of tomato powder (p<0.05). The consumer preferences on color, taste, and flavor, but not softness, were significantly affected by the amount of tomato powder incorporated in the sample (p<0.05). With respect to overall acceptability, the 20% sample received the highest mean score of 5.1, although this was not significantly different from the 10% sample or control (p>0.05). The incorporation of tomato powder, up to 20%, in the formulation of sponge cakes did not significantly influence the consumers' acceptability in all attributes tested.

The purpose of this study was to determine which fermented liquid fertilizer and application method yields the greatest amount of growth in red pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum MILL.) plants. Additionally, we investigated which extraction methods produce the most effective fertilizer with the highest levels of mineral nutrients. The liquid fertilizers used in this study were made from fish, bone and fish meal, red pepper leaves, and oil cake, and were extracted using fermentation or water and boiled water. In tomato plants, foliar-application of fermented fertilizer is known to promote more growth than application by drenching, regardless of the number of treatments (once or twice). In our studies, however, drenching with fertilizer promoted growth more effectively than foliar-application in red pepper plants. Studies in both tomato and red pepper have shown that the number of treatments does not significantly alter growth. Liquid fertilizers produced by a fermentation-extraction method promoted greater levels of growth in tomato compared to red pepper, and growth was greater when fertilizers were applied 20 (rather than 40) days post-sowing. Red pepper and tomato shoot fresh weight were affected more by fermented fertilizers than plant height 20 days post-sowing. In red pepper, we observed increased shoot fresh weight when using fermented liquid fertilizers with concentrations of 0.1% or greater. Tomato shoot fresh weight increased similarly in response to fermented fertilizer treatments at the same concentration levels, except those derived from fish. Fermented fish liquid fertilizer was only effective in increasing tomato shoot fresh weight in concentrations exceeding 1%. Red pepper and tomato shoot fresh weight also increased more than plant height in our studies using fermentation liquid fertilizers at 40 days after sowing. Red pepper fresh weight increased with application of bone + fish meal, red pepper leaf, and oil cake fertilizers at concentrations of 0.1%, but not with fish liquid fertilizer in concentrations under 0.5%. Shoot fresh weight in tomato increased with all liquid fertilizers. Growth in red pepper and tomato may be influenced by different kinds of fertilizers due to combinations of macro- and micro-nutrients, or specific macro-nutrients such as nitrogen, phosphoric acid, and potassium. The mineral nutrients found in fish, bone and fish meal, red pepper leaves, and oil cake were not easily extracted by fermentation; thus, liquid fertilizers made using water and boiled water methods more effectively promoted growth in red pepper and tomato due to the larger amounts of macronutrients eluted.

This study aimed to investigate the physicochemical characteristics of fish meal, bone meal, and sesame oil cake, which are readily available by-products from agriculture and fisheries, during the process of liquid fertilizer fermentation, and to examine the effects of liquid fertilizer application on seed germination and growth of tomatoes. During processing the fermentation for liquid fertilizers by using fish meal, bone meal, and sesame oil cake liquid fertilizers, the pH of the fertilizer increased in the order of bone meal > fish meal > sesame oil cake, and the concentration increased rapidly up to 30 days in all types of liquid fertilizer. The nitrogen content of the liquid fertilizers increased as fermentation progressed in the order of fish meal > bone meal > sesame oil cake. The phosphorus content increased as fermentation progressed and the highest was 1.0 % in the liquid fertilizer of sesame oil cake. The germination rate and its index of radish seeds were compared for different dilutions of each of the liquid fertilizers. Excluding the 10-fold dilution of the fish meal and oil cake liquid fertilizer, all the treatment groups showed a germination rate ≥ 95 % and the germination index tended to increase with dilution rate of liquid fertilizers. For responses of tomato growth, there were no significant differences among the liquid fertilizer treatment groups; however, the organic content, microbial density, and microbial biomass C in the soil were higher than chemical fertilizer treatment. These results demonstrated that there were differences in the characteristics of liquid fertilizers depending on the materials used, and that liquid fertilizer can be used for nutrition management for the organic crop cultivation.

Tomatoes are rich in nutrients and have many beneficial advantages on human health. Four cherry tomato supplementation diets (CTSDs) were prepared from the juice and cake of fresh and processed (heat-treated) cherry tomatoes. Rats were fed CTSDs for 28 days and the changes in health indices in the serum were analyzed. CTSDs significantly decreased (P < 0.05) food efficiency ratio compared with the control. CTSD feeding significantly increased (P < 0.05) the high-density lipoprotein cholesterol level compared with the control, which resulted in a significant (P < 0.05) decrease in coronary artery risk index and atherogenic index. Furthermore, CTSD feeding increased serum serotonin level. These results indicate that CTSD shows antihyperlipidemic effect.

BACKGROUND: In this study, 5 different treatments such as non-treatment, mixed expeller cake 1.0 N (standard nitrogen fertilizer), rice straw, rice straw+mixed expeller cake 0.5 N, rice straw+mixed expeller cake 1.0 N were performed over 4 cropping seasons over 2 years in order to identify the optimal application rate of mixture of rice straw and mixed expeller cake, organic source in organic cultivation of tomatoes. METHODS AND RESULTS: There was no difference in all treatments in case of 200 mg/kg in the nitrate nitrogen content in soil prior to the first cropping season test under the criteria for nitrogen nutrient based on yield of crops, cultivation without fertilizers seems possible. But in the second cropping season, no treatment and rice straw showed the reduction of yield and in the third cropping season, rice-straw+mixed expeller cake 0.5 N treatment showed the significant difference. The content of nitrate nitrogen in soil prior to cropping seasons was evaluated in 160 mg/kg and standard fertilization such as mixed expeller cake, source of nitrogen, are needed due to the deficiency of nitrogen. In terms of application of organic resources, rice straw showed the effects of improvements on physical properties of soil such as bulk density, cation exchange capacity and humus contents, but the mixed expeller cake did not show any significant differences in improvements on physical properties of soil. CONCLUSION(s): Fertilizer management in organic cultivation of tomatoes is thought to produce the reliable quantity of crops as well as keep the high quality of soils by using the optimal application rate of mixed expeller cake according to the contents of nitrate nitrogen in soil and rice straw which improves the physical properties of soil.

Sprague-Dawley rats were fed with normal (Control), high cholesterol (HC), and high cholesterol containing 3.5% pectin-hydrolytic activity industrial enzyme (Viscozyme L)-treated tomato cakes (ETC) for 4 weeks. In the first week, the weight gain of the HC-fed group was significantly increased to 151.7% (p<0.05), compared to the 115.4% weight gain of the ETC-fed group. The feed efficiencies of the Control- and ETC-fed groups ($0.236{\pm}0.041$ and $0.447{\pm}0.030$, respectively) were significantly different to those of HC-fed group ($0.355{\pm}0.034$) (p<0.05). The kidney and epididymal fat pad of the rats fed with ETC were decreased to 0.303 g and 0.274 g, respectively. There were no significant differences in serum cholesterol, triglycerides, high density lipoprotein-cholesterol or low density lipoprotein-cholesterol levels between the HC- and ETC-fed groups. The ETC-fed group exhibited approximately a 1.1-fold higher total antioxidant activity determined by 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radicals than the HC-fed group at 2 weeks. Glutathione peroxidase activity of the ETC-fed group exhibited 2.5-and 1.3-fold increases at 2 and 4 weeks, respectively.

The study was compared for growth and yield of cherry tomato (Lycopersicon esculentum var. cerasiforme) crops as affected by various homemade liquid fertilizer (LF), commonly applied in the environmentally friendly farmhouses. LF treatment included UT (untreatment, water), OC (oil cake), BF (bone+fish meal), FA (fish amino meal), SO (sesame oil meal), and SF (starfish). Seasonal pH and EC in SO- and SF-LF rapidly decreased at 30 days after the storage, which were the highest EC of 0.6 - 0.8 dS/m, followed by BF-LF with 0.4 dS/m EC. T-N concentration in LF was the highest on the SF (0.0062%), followed by SO (0.0059%) and BF materials (0.0030%), which were all the great for the K concentration in the LF. P and Ca concentrations were the highest on the FA-LF, with the highest Mg concentration observed on the vegetable SO-LF. Soil EC was the highest on the SF-LF plots of 0.74 dS/m, with no significant differences between the treatments observed on the macro-nutrient concentrations in the soil and leaf. Leaf dry weight, leaf temperature, stem diameter, and plant height were investigated at once per 15 days. UT-LF reduced the leaf dry weight at all the measurement time while the plant height was low at an initial measurement but increased and similar to the other homemade LF treatments at a later measurement. Fruit yield and average fruit weight were the lowest on the UT-LF plots at 75 days after fertigation. Fruit diameter was increased by the BF-LF and SF-LF, with the highest fruit soluble solid contents and fruit coloring observed on the FA-LF. BF-LF maintained high fruit firmness.
