Yackwa is used as one of foods prepared for traditional rituals and holidays and enjoyed as snacks. Since Yackwas are fried, they contain oil, which can cause rancidity and undermines the freshness of Yackwas during distribution to retailers, not to mention a high level of calories. The study aims to develop baked Yackwas and analyze the quality in terms of calorie levels and characteristics by baking Yackwas in oven. Calorie level was 4.65 kcal/g in fried Yackwa, 3.96 kcal/g in baked Yackwa, and 2.95 kcal/g in baked peanut Yackwa prior to dip coating of grain syrup. baked Yackwa showed hardness of 13476.33 g/cm2 before dipping in grain syrup, which was harder than 1912.56 g/cm2 of fried Yackwa. After grain syrup coating, hardness of baked Yackwa reduced more significantly, compared with that of fried Yackwa, as grain syrup permeated through texture of Yackwa. And less hardness makes baked Yackwa tastier. Sensory evaluation was measured in a 5-point scale. Scores for texture and taste of baked Yackwa outpaced those of fried Yackwa. Score for the overall quality was 3.65 in baked Yackwa and 3.25 in baked peanut Yackwa, compared to 2.85 of fried Yackwa, indicating a higher potential of commercializing(p〈0.05).

Background : We are Corporation of Reborn International that studies herbal medicine (Hydroponics Peanut sprout) and natural substance hydroponics. Our work is hydroponically grown peanut sprouts. This introduce, mouse allergic efficacy test and peanut tissue culture were performed. Methods and Results : The peanut sprouts have been widely used for long time of years in many Asian countries. P. sprouts germinated from peanuts, which contain 4 times higher resveratrol compounds than peanuts. The resveratrol have bioactivity effects as anti-inflammatory and anti-cancer. Especially, Our virgin premium peanut sprouts oil (cold pressure; low temperature extraction), natural substance oil produced mainly in peanut sprouts are used for valuable foods and cosmetic that supply essential fatty acids for humans as well as industrial raw functional materials production. In this work, large scale-up production of peanut sprout using hydroponics. Using extracts of peanut sprouts, various efficacy screening, animal test (in vivo, in vitro), and analyzes were also performed. Also, the culturing the peanut callus for increasing the contents of a specific useful ingredient were cultured in modified Murashige-Skoog/MS (sucrose 2%, agar 0.8%, pH 5.7) solid and liquid medium. It was examined that 0, 1, 3, 5, 10 ㎎/ℓ of NAA and 0, 1, 3, 5, 10 ㎎/ℓ of IBA were the callus and shoot induction. It's, developed sample model of food products of various formulations or form of including from peanut sprout extracts. Conclusion : The essential amino acids (composition unsaturated fatty acid) and resveratrol were abound to the extracts. Also, The blood circulation and allergy improvement effect was excellent. And toxicity were not detected in efficacy. Tissue culture screening work, It’s examined that〈 1.0 ㎎/ℓ of NAA and〈 3.0 ㎎/ℓ of IBA were the best composition. However, depending on the purpose of securing the functional material, a more detailed investigation is needed. So, future work is induce roots callus and shoot. The shown results can be applied as sources for functional food, cosmetic, pharmaceuticals, and material.

The present study set out to investigate the adsorption of Cd(II) ions in an aqueous solution by using Peanut Husk Biochar (PHB). An FT-IR analysis revealed that the PHB contained carboxylic and carbonyl groups, O-H carboxylic acids, and bonded-OH groups, such that it could easily adsorb heavy metals. The adsorption of Cd(II) using PHB proved to be a better fit to the Langmuir isotherm than to the Freundlich isotherm. The maximum Langmuir adsorption capacity was 33.89 mg/g for Cd(II). The negative value of ΔGo confirm that the process whereby Cd(II) is adsorbed onto PHB is feasible and spontaneous in nature. In addition, the value of ΔGo increase with the temperature, suggesting that a lower temperature is more favorable to the adsorption process. The negative value of ΔHo indicates that the adsorption phenomenon is exothermic while the negative value of ΔSo suggests that the process is enthalpy-driven. As an alternative to commercial activated carbon, PHB could be used as a low-cost and environmentally friendly adsorbent for removing Cd(II) from aqueous solutions.

Cheonggukjang was prepared by addition of peanut (Arachis hypogaea L.) powder in order to improve its quality and functional properties. The physicochemical and sensory properties of Cheonggukjang added peanut powder were investigated, after adding the peanut powder with the amount of 5, 15 and 25% (w/w). The proximate composition of peanut powder was as follows: moisture, 1.80%; crude protein, 24.9%; crude lipid, 48.3%; crude ash, 2.90%; and carbohydrates, 22.1%. Crude protein and lipid content of Cheonggukjang increased with increaes in the amounts of peanut powder, while the moisture content decreased. Calcium and amino acid contents showed disparity depending on the increasing addition of peanut powder. Cheonggukjang containing 15% (w/v) peanut powder was found to be highest calcium contents. The major amino acids of Cheonggukjang were glutamic acid, aspartic acid, lysine, leucine, arginine and proline. Depending on increasing amounts of peanut powder, the L and b values (measured using Hunter’s color values) were decreased, while the a value was increased. In addition, pH was decreased as the amount of peanut powder was increased. Sensory scores of Cheonggukjang containing 15% (w/v) peanut powder were best when considering both quality characteristics and sensory evaluation. This study suggested that peanut powder could enhance the quality and functionality of Cheonggukjang further.

This study was conducted to develop a fast and efficient screening method to determine the quantity of fatty acid in peanut oil for high oleate breeding program. A total of 329 peanut samples were used in this study, 227 of which were considered in the calibration equation development and 102 were utilized for validation, using near infrared reflectance spectroscopy (NIRS). The NIRS equations for all the seven fatty acids had low standard error of calibration (SEC) values, while high R2 values of 0.983 and 0.991 were obtained for oleic and linoleic acids, respectively in the calibration equation. Furthermore, the predicted means of the two main fatty acids in the calibration equation were very similar to the means based on gas chromatography (GC) analysis, ranging from 36.7 to 77.1% for oleic acid and 7.1 to 42.7% for linoleic acid. Based on the standard error of prediction (SEP), bias values, and R 2 statistics, the NIRS fatty acid equations were accurately predicted the concentrations of oleic and linoleic acids of the validation sample set. These results suggest that NIRS equations of oleic and linoleic acid can be used as a rapid mass screening method for fatty acid content analysis in peanut breeding program.
