Plant-based, grain-free, and gluten-free diets have been the focus of recent research, as part of the premiumization trend in dog food. However, the lack of comprehensive information regarding carbohydrates in dog food makes it difficult to produce nutritionally balanced meals. Therefore, we aimed to evaluate the nutritional value of carbohydrate ingredients commonly used in commercial dog foods. First, using data from Euromonitor, we investigated the trends in the dry dog food industry and analyzed the annual volume of dry dog food sales, as well as the dog population from 2010 to 2021 in Korea. The growth of the market was greatest in 2021, when the total value of sales of premium dry dog food was 254.3 billion KRW (Korean won) more than in 2010. In addition, sales of dry dog food by age category were marked by a significant increase (404.8%) in the market for dry food for senior dogs. Second, we examined the frequency of carbohydrate ingredients used in dry dog food and conducted a proximate analysis of the top 10 most frequently used ingredients. Subsequently, we analyzed the crude protein, crude fat, and nitrogen-free extract in the carbohydrate ingredients based on dry matter (DM) and calculated the ratio of metabolic energy content supplied from each nutrient in the carbohydrate ingredients. The ratio of metabolic energy content in the carbohydrate ingredients indicated that mung beans had the highest crude protein content (31.3%), whereas oats exhibited the highest crude fat content (23.3%). Sweet potatoes had the highest nitrogen-free extract content, measuring at 93.6%. The results of this study are expected to provide a valuable foundation for the growth and development of the domestic dog food industry, while also contributing to a deeper understanding of the specific role of each ingredient as a carbohydrate source.

The purpose of this study was to investigate the anti-obesity effects of crude saponin (CS) in Korean red ginseng (KRG) on rats fed a high fat (HF) diet. Methods: Male Sprague-Dawley (SD) rats were divided into a normal diet group and a high-fat (HF) diet group. The HF diet group became obese from being fed a HF diet over five weeks. The normal diet group were fed a normal diet. Each CS group of the normal diet group and HF diet group was administered CS (200 mg/kg, i.p.) for three weeks, the control group of both types was administered normal saline (1ml/kg, i.p.) instead of CS. Each group had 5 rats. Results: After administration of CS, the body weight, food consumption, adipose tissues, and expression of appetite peptides such as leptin and neuropeptide-Y (NPY) were investigated in the HF diet group as well as the normal diet group. Administration of CS reduced body weight, food intake, and fat content in the HF and normal diet groups. After CS administration, NPY expression and leptin were lower in the HF diet group. Conclusions: Our results suggest that CS may be useful in the treatment of obesity, especially of type qixu (氣虛).

This experiment was carried out to compare chemical composition, TDN yield of corn-soybean intercropping and corn monocropping forage plants at different harvesting time and obtained the following results. 1. In both cropping systems, the content of chemical composition of forage were changed same pattern in growing stage. The content of crude protein in corn-soybean intercropping forage at yellow stage increased more than that of corn nonocropping forage, while the crude fat in corn monocropping forage plants increased than that of corn-soybean intercropping forage plants at mature stage. 2. The crude fiber, crude ash, ADF content of forage plants in both cropping system decreased same pattern in growing period, however, NFE content of forage increased with maturity. 3. TDN yield of corn-soybean intercropping and corn monocropping forage plants at yellow stage obtained similar results and TDN yield per 10a in intercropping and monocropping were 1006.lkg and 978.6kg, respectively. 4. Consequently, corn-soybean interaopping system could be increased crude protein yield without decreasing of dry matter yield in comparison with corn monocropping system for corn silage.

Dynamic parameters of biochemistry including the contents of soluble carbohydrate (SC) , crude fat (CF) , fatty arid (FA) and soluble protein (SP) in American send (Panax qufnquelolium L.) seed are reported in the present paper. When embryo ratio (ER) increased from 7.31 to 20.48%, the SC content decreased from 4.08 to 1.16%. After that, SC content changed little. The CF content decreased successively from 34.50 to 14.40% from the beginning to the end during the embryo afterripening. The changes of FA content did not correlate with that of ER and the changing range of SP content was not large during the seed stratification. All of these may provide some information for understanding the dormancy mechanisms of American seng seed.

This study evaluated the general nutritional ingredients such as crude fats, crude ashes, crude proteins, total polyphenols, and total flavonoids in 18 kinds of edible tree sprouts. The tree sprouts of Philadelphus schrenckii, Lycium chinense, and Morus alba had the highest crude fat, crude ash, and crude protein content, respectively. The tree sprouts of Cedrela sinensis (CSS) with high ABTS⁺ radical scavenging activities had a high content of total polyphenols (175.65 mg/g ext.) and total flavonoids (75.18 mg/g ext.). The simultaneous determination of flavonoids such as rutin, isoquercitrin, quercitrin, afzelin, and quercetin in CSS was conducted using high-performance liquid chromatography with a wavelength of 270 nm. Among the flavonoids, the content of quercitrin in CSS was the highest at 59.28 mg/g ext. This study also aids the quality control of many edible tree sprouts by analyzing the general components, total polyphenols, and total flavonoids.

In order to obtain basic data for the preparation of rice flour, chemical properties of grain layers were compared using Chucheongbyeo and Samgangbyeo, which are Japonica and Tongil type rice, respectively. The amylose contents of L6(center) layer in two different type of rice were the highest among 6 layers of rice grain tested. Reduction in amylose content was observed as the layer reached the surface, resulting in the lowest amylose content in the L0 layer. Amylose contents of L6 layer of Chucheongbyeo and Sangangbyeo were 3 and 2.2 times higher than those of L1 layer, respectively. Crude protein content of the L2 layer was the highest among 6 layers of rice grain tested and 2.2~2.5 times higher than that of whole milled rice. Crude fat content of grain layer was reduced as reaching the center layer. The crude fat contents of L6 layer of grain were 0.21% and 0.25% in Chucheongbyeo and Samgangbyeo, respectively. Most of free and bound lipids in L0 layer of two different rices were 69 : 31 and 79.5 : 20.5, respectively. Bound lipid content of grain layers increased as reaching the center layer. Major fatty acids in free lipids of both cultivars were linoleic acid, oleic acid, and palmitic acid. Linoleic acid content was higher than oleic acid in Chucheongbyeo, but oleic acid content was higher in Samgangbyeo. Palmitic and myristic acid contents of Chucheongbyeo were higher than those of Samgangbyeo, but stearic and linolenic acid contents were lower than those of Samgangbyeo.

The goal of this study was to make more efficient use of Ligularia fischeri which has both medical and cooking applications after freezing and drying. We manufactured Sulgidduk containing 0, 2, 4, 6 and 8% of Ligularia fischeri powder. Chemical analysis showed that Ligularia fischeri powder contained, 5.77% water, 19.97% crude protein, 1.89% crude fat, 13.12% crude ash, and 9.73% crude fiber. The water content of Sulgidduk to which Ligularia fischeri was added ranged from 37.72~40.20%. As more Ligularia fischeri was added, the L value and 'a' value increased, while the 'b' value did not significantly change. Optimal preference was for a 4% content of added Ligularia fischeri powder. Based on the results of this experiment, Sulgidduk manufactured with added Ligularia fischeri powder showed less hardness than the control group throughout a period of storage, and adequate addition of Ligularia fischeri powder can effectively enhance the storability of Sulgidduk containing Ligularia fischeri.

대전 및 충청 지역에서 판매되고 있는 즉석식품의 조지방 및 트랜스지방산의 함량을 조사하고자 찹쌀도넛과 꽈배기 각각 6종, 고구마 스틱 2종, 토스트 9종, 그리고 멀티플렉스 극장 팝콘 11종 등 총 41종을 수거하여 분석하였다. 조지방 함량은 멀티플렉스 극장 팝콘 13.74${\sim}$38.09%로 가장 높았으며, 고구마 스틱 20.82${\sim}$20.88%, 오징어 튀긴 9.37${\sim}$25.53%등의 순이었다. 수거한 시료는 유탕처리 식품이었으며, 멀티플렉스 팝콘은 전자렌지용 팝콘과 달리 트랜스지방산 함량이 매우 적게 분석된 것으로 보아 식물성 부분 경화 유지를 상요하지 않은 것으로 보인다. 트랜스지방산 함량은 대부분 1 g(g/100 g food) 미만으로 낮았으나, 멀티플렉스 극장 팝콘 중 한 시료만이 3.08 g(g/100 g food)으로 높게 나타났다.
