  • Cocoa bean husk is an important by-product of the cocoa industry. This study was conducted to measure the changes in the quality characteristics of sausage with added cacao bean husk powder (0, 0.25, 0.5, 1, 1.5, and 2%; ascorbic acid 0.2%) at 4℃ for 15 days. The total polyphenol, total flavonoid, DPPH, and ABTS+ radical scavenging activity of sausages increased with the addition of cocoa bean husk powder (p<0.001). As the amount of added cocoa bean husk powder increased, quality deterioration characteristics such as pH increase, redness discoloration, lipid oxidation, protein degradation, and texture change during storage were decreased (p<0.05). In particular, 1% sausage was shown to inhibit TBARS and VBN, similar to ascorbic acid-added sausage. In terms of sensory characteristics, the 0.5 and 1% sausages received the highest score for overall preference. Therefore, we concluded that addition of 1% cocoa bean husks to sausages improved their storage characteristics and palatability.

  • Flavor components focused on the methyl pyrazines(2,3-dimethyl pyrazine, 2,3,5-trimethyl pyrazine, tetramethyl pyrazine) of microwave-roasted cocoa beans were determined and compared with those of conventionally-roasted cocoa beans. Domestic microwave oven was modified to design the microwave roasting system. Temperature measurement technique using thermocouple probes was developed to determine the center temperature of cocoa beans during microwave roasting. Microwave roasting was carried out under two different conditions. Under the first condition, roasting time was fixed to 30 min, while roasting temperature was varied to $110^{\circ}C,\;120^{\circ}C,\;130^{\circ}C,\;140^{\circ}C,\;and\;150^{\circ}C$ Under the second condition, roasting temperature was fixed to $130^{\circ}C$, while roasting time was varied to 5 min, 10 min, 20 min, and 30 min. Conventional roasting was done at $120^{\circ}C$ for 15 min as a reference. Amount of methyl pyrazines and their ratios were influenced by microwave roasting temperature and roasting time. The most suitable methyl pyrazine ratio of cocoa beans was obtained at $140^{\circ}C$ for 30 min of microwave roasting.

  • The physicochemical properties of microwave-roasted cocoa beans such as color, degree of browning, pH, titrable acidity, organic acid, and sugar content were determined and compared with those of conventionally-roasted beans. Microwave roasting temperatures were 110, 120, 130, 140 and $150^{\circ}C$. Roasting times were 0, 5, 10, 20, and 30 min. Conventional roasting was done at $120^{\circ}C$ and 15 min as a reference. The pH had no relations with roasting temperature or roasting time. As roasting time and roasting temperature were increased, the titrable acidity values of roasted cocoa beans became higher than those of raw bean. But there were no differences among each condition. Color, degree of browning, and sugar content changed as roasting temperature and roasting time increased. The organic acid content of roasted beans increased but the degree of increase was different from organic acid to organic acid. Roasting by microwaves resulted in higher inner temperature of samples than the surface temperature. To increase roasting efficiency, the other heat sources should be used together with microwave.

  • Pregermination treatment of cocoa beans either with the testa, group PCB (+T), or without the testa, group PCB (-T), was studied here to determine whether this treatment (incubation up to 120 h at $25^{\circ}C$) has any effect on the levels of allergenic proteins or on chemical composition. Our proximate analysis included carbohydrates, proteins, and lipids. We used western blotting to measure changes in the amounts of allergenic proteins in the cocoa beans during the pregermination treatment. The protein and carbohydrate content of both groups (with or without the testa) decreased slightly during this treatment, whereas lipid content increased. Group PCB (-T) showed more rapid metabolic processes than did group PCB (+T) during the pregermination treatment. Western blot analysis showed that the cocoa beans contained an allergenic protein of ~28 kDa. Removal of the testa strongly reduced the amount of this allergenic protein after 72 h of the pregermination treatment. Generally, the pregermination treatment increased antioxidant activity in both groups. Significant differences in the antioxidant activity were observed between groups PCB (-T) and PCB (+T). Particularly, group PCB (-T) showed high antioxidant activity at 72 h of the pregermination treatment. Thus, the combination of cocoa beans without the testa and pregermination treatment (72 h) seems to be the optimal method for production of hypoallergenic cocoa beans rich in antioxidants for patients with allergic disorders.

  • Cacao bean husk (Theobroma cacao L.) contains a high level of dietary fiber and therefore can be used as raw material in food processing. The objective of the present study was to measure the physicochemical properties and sensory traits of emulsion-type pork sausages with various levels of cacao bean husk powder (0.25%, 0.5%, 0.75%, 1%, and 2%). The moisture content in cooked sausages increased as the level of cacao bean husk power increased, whereas the protein content decreased (p<0.05). With respect to color, as the level of cacao bean husk power increased, there was a decrease in lightness and yellowness, but there was a considerable increase in redness (p<0.05). Cacao bean husk powder exhibited a positive effect on emulsion stability and apparent viscosity. In the sensory evaluation, increased level of cacao bean husk increased flavor acceptability; the 0.75% and 1% treatment groups showed significantly high overall acceptability (p<0.05). The thiobarbituric acid reactive species content of cooked sausages indicated that with the addition of cacao bean husk powder significantly inhibited lipid oxidation in the sausages during refrigerated storage (p<0.05). Overall, the findings of the present study suggest that adding 0.75% and 1% cacao bean husk powder as a natural ingredient in sausages can help develop meat products with excellent qualities.

  • Caffeine is widely consumed ingredient and it belongs to alkaloids. Many foods that we intake contain caffeine ; coffee, tea cocoa, chocolate, and coke. And it is also added to many commercial remedies ; cold tablets, headache tablets, etc. Effect of caffeine that is known to us so far is as follows; 1. Remaining awake for long hours 2. Increasing concentration and decreasing fatigue 3. Increasing basal metabolic rate 4. decomposing glycogen and body fat and providing energy 5. Stimulating gastric acid 6. Increasing urinary excretion. Caffeine containing beverages(especially, coffee)are also favorite food in adult. In case of children and youth, chocolate and coke are favorite food. So, to intake caffeine containing foods moderately can be a vitality of life. But, a long-term intake or overdose of caffeine can result in many side effects. For example, headache, irritability, restlessness, hypertension, fetal abnormality, etc. Therefore, it is desirable that caffeine intake is under 300-400mg per day. To decrease intake of caffeine, 1. Use decaffeinated coffee 2. Product of decaffeinated coffee bean through gene transformation 3. Indicate content and function of caffeine on caffeine-food container 4.
