Objective: This study investigated the effects of dry radish leaf and root on the quality of pork patties during refrigeration storage. Methods: The patties were divided into the following three groups: the control containing 0% dry radish leaf root powder, RL1 containing 0.5% dry radish leaf root powder, and RL2 and RL3 containing 1% and 2% dry radish leaf root powder, respectively. Proximate composition, pH, cooking loss, microbial analysis, lipid oxidation analysis, color, texture profile analysis and sensory test were performed. Results: Moisture, crude protein, and crude ash contents in RL2 and RL3 were significantly higher than those in other groups (p<0.05), whereas crude fat contents in RL2 and RL3 were significantly lower than other groups (p<0.05). Lightness was significantly lower in RL2 and RL3 than in CON (p<0.05). Cooking loss for RL2 and RL3 were significantly lower than those for the other groups (p<0.05). The pH, thiobarbituric acid levels, and total plate counts of RL2 and RL3 were significantly lower than those of CON at days 7 and 14 (p<0.05). Hardness values of RL2 and RL3 were significantly lower than those of CON, whereas chewiness values were higher than those of CON (p<0.05). In addition, the juiciness of RL2 were significantly greater (p<0.05) than those of the other groups. Conclusion: Dried radish leaves and roots improved the proximate composition and quality characteristics of pork patties, providing a basis to produce high-quality patties with extended expiration dates. Thus, dried radish leaves and roots are effective ingredients for health or functional foods.

This study investigated the quality characteristics and antioxidant activity of Yanggaeng prepared with various amounts of watermelon radish flesh (WRF) powder, in ratios of 0 (control), 2.5, 5, 7.5, and 10% of the cooked white bean paste. The proximate composition, pH, sugar content, Hunter's color values, texture analysis, and antioxidative activities of Yanggaeng were examined. Increasing the amount of WRF in the Yanggaeng tended to increase the crude ash, carbohydrate, sugar, total polyphenol, total flavonoids, and anthocyanin contents, a value, DPPH and ABTS radical scavenging activities, with decreasing the moisture and crude protein contents, L and b values, and pH. Texture measurement scores in terms of springiness, chewiness for Yanggaeng showed that 2.5% or 5.0% group was higher than those of the control group. Hardness was higher in the sample groups than in the control group. In conclusion, the results show that Yanggaeng with up to 7.0% added WRF powder can be developed as products, and there is a possibility of developing health functional snack products using WRF powder.

Consumer's demand for higher dietary fiber and lower fat in processed foods are increasing. This study developed a low fat and high dietary fiber snack using egg whites and dry fermented radish powder obtained from Dongchimi fermentation. Quality characteristics, such as hardness, color, fat content and total dietary fiber, of the developed snack were conducted along with a hedonic test. As the amount of the fermented powder increased in the formulation, water content and snack hardness decreased. Up to 14.5% radish powder was added (or 9.54% dietary fiber; dry weight, w/w) to the formulation, and hedonic test found snack containing 4.8% (w/w) powder showed the highest scores for overall acceptability.

This study investigated the potential for using vegetable powders as a natural replacement for sodium nitrite and their effects on the physicochemical characteristics of alternatively cured pork products. We analyzed pork products subjected to four treatments: control (0.015% sodium nitrite), Chinese cabbabe powder (CCP) treatment (0.4% Chinese cabbage powder), radish powder (RP) treatment (0.4% radish powder), and spinach powder (SP) treatment (0.4% spinach powder). Among the vegetable powders prepared in this study, SP had the highest (p<0.05) nitrate content, while CCP had the lowest (p<0.05). The cooking yields from these treatments were not significantly different from each other. However, the products with vegetable powders had higher (p<0.05) pH and thiobarbituric acid reactive substances values than the control. Pork products with vegetable powders also showed lower CIE L^⁎ values and higher CIE b^⁎ values than the nitrite-added control. RP treatment had similar (p>0.05) CIE a^⁎ values to the control, while SP treatment had the lowest (p<0.05) CIE a^⁎ values. The residual nitrite content was lower (p<0.05) in the vegetable powder added pork products than in the control, although nitrosyl hemochrome and total pigment contents in the CCP and RP treatments were similar (p>0.05) to those in the control. The control, CCP, and RP treatments showed curing efficiencies greater than 80%, indicating that CCP and RP would be promising potential replacements for sodium nitrite. The results of this study suggest that RP may be a suitable natural replacement for sodium nitrite to produce alternatively cured meat products, compared to other leafy vegetable powders.

Raphanus raphanistrum subsp. sativus (radish) powder contains several bioactive com- pounds and is widely used in the food industry. In this study, we examined the sensory attributes (taste, color, flavor, texture, and overall acceptability) of commercially available milk, yoghurt, and kefir containing different concentrations of R. raphanistrum subsp. sativus powder. The organoleptic characteristics of commercially available milk, yoghurt, and kefir was significantly different with respect to taste, flavor, color, texture, and overall acceptability in the treated group (1%, 2%. 3%. and 4%) compared to the control (0%; p<0.05). In addition, the scores of taste, flavor, color, texture, and overall acceptability decreased in proportion to the increase in amount of radish-powder in commercially available milk, yoghurt, and kefir. When 1% R. raphanistrum subsp. sativus powder was added to commercially available milk, yoghurt, and kefir, they showed good results in organoleptic characteristics compared to the control group. Therefore, our results could be used as the basis for estimating changes in organoleptic characteristics on supplementation of various dairy products with R. raphanistrum subsp. sativus.

Castor oil cake is widely used as a raw material for organic fertilizers (OF) in Korea. Compared to other fertilizer raw materials, it is highly dependent on imports. In terms of replacing raw materials, dehydrated food waste powder (FDP) and castor oil cake have similar nutritional content, and if 30% is replaced, about 20% of the raw material cost can be saved. However, few studies on the effects on crop growth and soil properties when organic fertilizer and dry food waste powder are mixed and applied to the soil have been reported. The effects of an organic fertilizer made by mixing the commercial available organic fertilizer with dehydrated food waste (OF + FDP) on soil properties and the growth of two types of leafy vegetables (lettuce and young radish) were evaluated and compared with the performance of OF. The fresh weights of lettuce and young radish were the highest with OF amendment and stood at 114.3 and 119.0 g·plant^-1, respectively. These were followed by OF + FDP amendment, which produced 103.1 and 109.6 g·plant^-1, respectively. Compared to the control, OF and OF + FDP increased the lettuce fresh weights by about 69% and 52%, respectively, while the fresh weights of the radish were increased by about 223% and 207%, respectively. The soil pH, EC, total carbon content, and organic matter content in OF and OF + FDP increased. The mixture of dehydrated food waste powder and organic fertilizers is expected to improve soil quality and facilitate stable production of crops and contribute to the substitution of imported organic fertilizer raw materials.

We investigated the effects of different phosphate replacements on the quality of ground pork products cured with sodium nitrite or radish powder to determine their potential for achieving clean-label pork products. The experimental design was a 2×5 factorial design. For this purpose, the ground meat mixture was assigned into two groups, depending on nitrite source. Each group was mixed with 0.01% sodium nitrite or 0.4% radish powder together with 0.04% starter culture, and then processed depending on phosphate replacement [with or without 0.5% sodium tripolyphosphate; STPP (+), STPP (-), 0.5% oyster shell calcium (OSC), 0.5% citrus fiber (CF), or 0.5% dried plum powder (DPP)]. All samples were cooked, cooled, and stored until analysis within two days. The nitrite source had no effect on all dependent variables of ground pork products. However, in phosphate replacement treatments, the STPP (+) and OSC treatments had a higher cooking yield than the STPP (-), CF, or DPP treatments. OSC treatment was more effective for lowering total fluid separation compared to STPP (-), CF, or DPP treatments, but had a higher percentage than STPP (+). The STPP (+) treatment did not differ from the OSC or CF treatments for CIE L^* and CIE a^*. Moreover, no differences were observed in nitrosyl hemochrome content, lipid oxidation, hardness, gumminess, and chewiness between the OSC and STPP (+) treatments. In conclusion, among the phosphate replacements, OSC addition was the most suitable to provide clean-label pork products cured with radish powder as a synthetic nitrite replacer.

This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.
