This study has investigated the physicochemical and sensory characteristics of muffins supplemented with 0%, 5%, 10%, 15%, and 20% roasted safflower seed powder (SSP) in order to assess its applicability as a functional ingredient in baked goods. As the SSP content increased, the pH of both the batter and the muffins significantly decreased, whereas the height, volume, and specific volume of the muffins increased. Moisture content and baking loss rate were not significantly affected. Color analysis revealed that the L* and b* values decreased, whereas the a* values and total color difference (ΔE) significantly increased with higher SSP levels. Texture profile analysis showed that the hardness, gumminess, chewiness, and resilience decreased as SSP increased, whereas springiness improved. In the sensory evaluation, the overall preference was highest for the control (7.30), followed by the SSP 15 group (5.77), thus indicating that excessive SSP addition negatively affected consumer acceptance due to a darker color and rougher texture. However, the SSP 15 formulation achieved a favorable balance between health functionality and sensory quality. These results suggest that up to 15% SSP can be effectively incorporated into muffins in order to improve their functional value without compromising product quality or consumer satisfaction.

This study examined the effects of partially replacing wheat flour with roasted safflower seed powder (SSP) on brownie quality, using proportions of 0%, 5%, 10%, 15%, and 20%. The addition of SSP had no significant dose-dependent effect on pH. Although the highest moisture content was observed in SSP 20 brownies (8.48%), no significant differences were found among samples. Brownie thickness increased proportionately with the amount of added SSP. Volume and density also increased with higher SSP content. Brightness (L), redness (a), and yellowness (b) values were all highest in SSP 20 brownies, indicating that SSP content affects brownie color. Hardness exhibited an increasing trend, with the control group values at 331.38±12.85 and SSP 20 at 432.70±39.84. Sensory evaluations revealed a highest overall preference for the control group, followed by the SSP 10 group. These findings suggest that the addition of 10% SSP is appropriate for brownies.

본 연구는 식물공장에서 고흡수성 합성고분자(Super absorbent polymer; SAP)를 수경재배에서 배지로서의 활용가능성을 구명하고자 홍화 및 아마란스 새싹의 생육특성과 페놀함량 및 항산화도를 평가하였다. 대조구는 새싹 재배기(19 × 14 × 9cm, W × D × L)에 거즈를 깔고, 처리구에는 거즈 위에 SAP 를 추가하여 비교 분석하였다. 홍화 새싹 종자를 30°C의 증류수에 5시간 동안 침지한 뒤, 새싹 재배기에 파종 후 식물생장 상에서 재배하였다. 식물생장상의 내부 온도는 25 ± 1°C, 습도는 70 ± 4%로 유지되었고 광조건은 35 ± 6μmol·m -2 ·s -1 (광 주기 12h)로 설정하였다. 아마란스 새싹은 새싹 재배기에 파종 후 식물생장상 내부 온도 25 ± 2°C, 습도는 70 ± 5%, 광조건은 188 ± 10μmol·m -2 ·s -1 (광주기 16h)로 설정하였다. SAP 의 기본적인 특성으로 물리/화학적 분석과 홍화 및 아마란스의 발아율과 생육특성 및 기능성 물질을 분석하였다. 홍화는 발아율, 생육 및 기능성 물질에서 처리구와 대조구간 차이가 없었으나, 아마란스는 생육 측면에서는 대조구와 차이가 없었으나 발아율, 건물중, 페놀함량 및 항산화도에서 처리구가 각각 1.16배, 1.16배, 1.40배, 1.12배의 높은 결과를 보였다. 결과적으로, 이번 연구를 통해 식물공장에서 SAP을 활용한 새싹재배가 가능할 것으로 판단하였으며 추후 SAP가 식물 생리적으로 작용하는 연구가 필요할 것으로 사료된다.

This study was carried out to investigate the chemical properties of safflower seeds cultivated at some areas in Korea. Safflower was used as one of the functional foods and medicinal plants for many centuries. Porximate compositions of safflower seeds were moisture, 4.8~8.1%, crude protein 16.5~19.5%, crude ash 2.7~3.3%, curde fiber 38.5~43.4%, and crude fat 16.6~24.4%, respectively. Glutamic acid, aspartic acid and arginine were the major amino acids and their contents were 2,587.4~3,143.5 mg%, 1,315.8~1,654.8 mg%, and 1,171.9~1,484.2 mg%. K, P, Ca, and Mg were major minerals and their contents were 611.6~886.3 mg%, 501.5~596.7 mg%, 208.5~641.2 mg%, and 530.6~639.5 mg%, respectively. The free sugars that were identified include raffinose, sucrose, glucose, fructose. α-tocopherol content was 0.14~3.82 mg%. Contents of vitamin C was 0.43~3.39 mg%. The safflower seeds fatty acids were palmitic acid, stearic acid, oleic acid, linoleic acid and linoleic acid. The major fatty acid was linoleic acid it’s content was 74.8~82.9%.

To determine the medicinal properties of Pleurotus cornucopiae and Safflower Oil (PS), the osteoblast effect was investigated. PS can prevent estrogen deficiency-induced bone loss. It was taken the measurements of biochemical factors such as serum osteocalcin, alkaline phosphatase, IGF-1, and bone status. Forty adult female Sprague-Dawley rats were randomly assigned to four equal groups for 12 weeks of treatment: (1) sham operation (SHAM) + vehicle; (2) ovariectomy (OVX) + vehicle; (3) OVX + 17β-estradiol (25 μg/kg); (4) OVX + PS (300 mg/kg/d, PO). At the end of the experiment, bone turnover, and trabecular microarchitecture were assessed by micro-computed tomography (micro-CT), and histopathology, respectively. Ovariectomized rats experienced remarkable increases in global volumetric bone density, and trabecular microarchitecture deterioration. These OVX-induced pathological changes are reversible in that most of them could be mostly corrected upon 17β-estradiol treatment. PNS treatment significantly prevented bone mass loss and microarchitecture deterioration. Moreover, PS enhanced osteoblast activity but suppressed osteoclast turnover, as evidenced by decreased levels of serum C-terminal telopeptides of type I collagen and elevated levels of alkaline phosphatase. PS mitigates estrogen deficiency-induced deterioration of trabecular microarchitecture.

This study was conducted to get beneficial information of fatty acid compositions and antioxidant resources from safflower genetic resources. The fatty acid compositions and antioxidant activities in 128 safflower germplasm collected from South Asia and Africa were evaluated using gas chromatography and spectrophotometer, respectively. The total oil contents in safflower germplasm were 15.8 ~ 32.2%. The unsaturated fatty acid and linoleic acid were 89.4 ~ 93.3%, and 15.5 ~ 80.4%, respectively. Six accessions (K184652, K184658, K184662, K184671, K185831, and K185832) from South Asia exhibited high oleic acid contents. Variation of DPPH and ABTS activities ranged from 0.8 ± 0.28 to 7.6 ± 0.06 μg ASC mg-1 and from 23.1 ± 1.72 to 134.7 ± 1.25 μg Trolox mg-1, respectively. Total polyphenol contents ranged from 5.1 ± 0.17 to 52.0 ± 1.24 μg GAE mg-1. The antioxidant activities and fatty acid compositions were not different between the South Asia and Africa germplasm, while oil contents of seeds were higher in South Asia germplasm. DPPH values had positive correlation with ABTS activity (r = 0.862**) and total polyphenol contents (r = 0.864**) whereas oleic and linoleic acid showed strong negative correlation (r = −0.998**). Principal component analysis based on oil and antioxidant traits exhibited that the first four principal components together expained 85.0% of the total variation.

Periodontitis is an inflammatory disease, which destroys the connective tissue and the alveolar bone. Recently, it has been suggested that the effect of natural substances could be induced into an anti-inflammatory environment. However, the effect of Safflower seed extract (SAF-M) associated with periodontitis has not been investigated yet. Therefore, the purpose of this study was to assess the anti-inflammatory effects of SAF-M. Cytotoxicity was assessed through MTS analysis using hGF and hPDL cells. Periodontitis was induced by injecting LPS into gingival tissue on the maxillary molars of rats (45 μg LPS/one time, 3 times a week for 3 weeks). SAF-M was administered daily at 30 mg/kg and 100 mg/kg. Alveolar bone resorption was evaluated through the micro-CT. hGF and hPDL cells showed differential cytotoxicity in response to SAF-M at 5 mg/ml and 1 mg/ml concentrations. Micro-CT showed reduction of the alveolar bone resorption in the SAF-M treatment group. These results suggested that SAF-M is a potential therapeutic agent for periodontitis.

One hundred seventy two accessions of safflower, collected in four countries were investigated for their morphological and biochemical characters in 2014. The accessions were categorized into two groups; South-Central (S-C) Asia and South-West (S-W) Asia, and each group was represented the accessions of two countries. Variation in morphological and biochemical characters was observed between two groups of accessions. The average value of seed weight and range of variability were higher in S-C Asia accessions while S-W accessions exhibited the variation in plant height, leaf length and days to flowering. The average value of oleic and total oil content were higher in S-C Asia accessions, and the values were 19.8%, and 231.4 mg.g-1, respectively, while the range of variability for total oil content was higher in S-W accessions. Plant height exhibited a significant positive correlation with days to flowering (r = 0.625**). Palmitic acid had positively correlated with stearic acid (r = 0.282**) and linoleic acid (r = 0.444**). Oleic and linoleic acid showed a strong negative correlation (r = -0.977**). The first three principal components explained 57% of the total variation. Morphological and biochemical variation exist in different groups of accessions could be useful to breeder for developing new safflower cultivars with high oil quantity and quality.

Background : The purpose of this study is to select potential genetic resources from safflower germplasm collected from India based on their oil compositions and agronomic characteristics. Methods and Results : The agronomic characteristics were measured during the growing period of the safflower. Total oil contents were recovered by Soxhlet extraction and the fatty acid compositions were analyzed by using gas chromatography. The mean of plant height, leaf length and leaf width were 100.19 ㎝, 20.49 ㎝, and 7.29 ㎝, respectively. The percentage of leaf margin with serration was 95%, and 2% of the total resources didn’t have spines on the involucral bract. K185681 had no spines on the involucral bract and the plant height was the smallest. 73% of the flower of safflower was yellow. 68% of safflower germplasm changed flower color from yellow to red. Total oil contents of 267 safflower accessions showed a significant variability among the entire domain of collections and ranged from 5.81 to 38.91%. Palmitic and stearic acid were ranged from 4.98 to 6.65%, and 1.82 to 2.73%, respectively. Oleic and linoleic acid showed a wide variation which ranged from 10.53 to 22.27%, and 69.46 to 81.26%, respectively. Linolenic acid was ranged from 0.06 to 0.13%. K185639 and K185639 had the highest total oil contents and linoleic acid, respectively. Cluster analysis based on oil composition and agronomic characteristics data divided the germplasm collections into three groups. Group Ⅲ having 114 accessions contained accessions with taller plant height than the other groups. Group Ⅱ having 68 accessions, the main color of flower was white but the other groups were yellow. Oleic acid showed a strong negative correlation (r = -0.9691**) with linoleic acid. Principal component analysis (PCA) based on the oil compositions and agronomic characteristics data revealed that the first two principal components (PC1 and PC2) together explained 36.28% total variation. Conclusion : These results showed that K185681, K185639 and K185639 could be useful to develop breeding and functional food.
