This study was performed to determine physicochemical and sensory quality of low-fat pork loaf containing silkworm powder and vegetable worm (Paecilomyces japonica). Total 2% of fat replacer (soy protein isolate:maltodextrin:$\kappa$-carrageenan:water=1:0.5:0.5:10, w/v) was added. The loaf was separated into CTL (control), T1 (0.2% silkworm powder), T2 (0.2% vegetable worm), T3 (0.4% silkworm powder), T4 (0.4% vegetable worm), T5 (0.1% silkworm powder+0.1% vegetable worm), and T6 (0.2% silkworm powder+0.2% vegetable worm). Pork loaf of T3 showed the highest pH value and cooking loss of pork loaves containing silkworm and vegetable worm was higher than control at day 5. 2-Thiobarbituric acid reactive substances of T2 and T5 showed significantly lower values than control and those additives may reduce lipid oxidation of meat. Overall acceptability was not adversely influenced by silkworm powder and vegetable worm at day 0 and 5. These results indicated that those silkworm powder and vegetable worm could be utilized for pork product industry.

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.

This study was performed to evaluate the quality change of pork patties containing silkworm powder and vegetable worm (Paecilomycis japonica) stored for 9 days at $5^{\circ}C$. pH values were higher in treatment groups than that in controls by storage day 6. L (lightness) and a (redness) value were decreased with increasing addition of silkworm powder and vegetable worm powder in pork patties (p<0.05). However, b value (yellowness) was increased with increasing addition amounts of the silkworm powder and the vegetable worm powder (p<0.05). Water holding capacity (WHC) of pork patties was not affected by the silkworm powder and the vegetable worm powder, while pork patties containing 0.4% silkworm powder (T2) showed low cooking loss (p<0.05). Pork patties containing either silkworm powder and vegetable worm alone or a combination of them showed lower lipid oxidation value than that of control (p<0.05). Sensory preference of pork patties was decreased with increased of storage days. The overall acceptance was higher in treatment groups than at control groups at the initial day (p<0.05), yet no significant difference was found during storage. From these results, 0.4% silkworm powder decreased not only cooking loss but also lipid oxidation of pork patties. Also, no adverse effect was found in water holding capacity (WHC) and sensory preference of pork patties. Therefore, the silkworm powder and the vegetable worm powder could be useful to pork meat product industry as additives.

This study was performed to investigate the effects of vegetable sprout powder on serum and adipose tissue lipid metabolism in rats fed high-fat diet for 4 weeks for induction hyperlipidemic model rat. Weight-matched male Sprague-Dawley rats were assigned to five groups according to dietary fat level (10% or 20% of diet wt.) and mixture of vegetable sprout powder levels (5% or 10% 10% or 20% of diet wt.). Vegetable sprout powder was the mixture of same amounts of dried barley, broccoli, rapeseed, alfalfa, radish, mustard, buckwheat and brussels sprouts. Experimental groups were normal fat diet with 5% cellulose (NF-C), high fat diet without fiber (HF-N), high fat diet with 5% cellulose (HF-C), HF-C diet with 5% vegetable sprout powder (HF-CSL), and HF-C diet with 10% vegetable sprout powder (HF-CSH). The body weight of HF-N group increased 16% compared with the NF-C group, while it was decreased by 15% and 22% for HF-CSL group and HF-CSH group, respectively. Fat mass and fat cell size of adipose tissue were lower in HF-CSL group and HF-CSH group compared with HF-C group, and lower in HF-CSH group compared with HF-CSL group. Serum triglyceride, total cholesterol and LDL-cholesterol contents were markedly decreased by vegetable sprout powder containing diet, while the serum HDL-cholesterol and phospholipid contents were higher in vegetable sprout powder containing diet in a dose-dependent manner. Leptin and insulin levels in serum showed a decrease in HF-CSH group. Significantly increased contents of triglyceride, total cholesterol, LDL-cholesterol, leptin and insulin in the serum of HF-N group were returned to normal or even below normal levels by feeding 10% vegetable sprout powder diet. The increased activities of NADP-malate dehydrogenase (ME), glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) and lipoprotein lipase (LPL) in adiposetissue by HF-N group were decreased to the activity of normal fat group by feeding vegetable sprout powder in a dose-dependant manner. These results indicate that lipid metabolism in rats fed high-fat diet was suppressed by feeding vegetable sprout powder.

Previous research has indicated that radish powder could be a suitable replacement for chemical nitrite sources in alternatively cured meat products. However, the effects of radish powder level on the physicochemical properties of cured meat have not been systematically studied. In this study, we aimed to investigate the effects of varying concentrations of radish powder and incubation time on the physicochemical properties and cured meat pigments of alternatively cured meat products. We divided our experimental setup into seven groups with different radish powder concentrations and incubation times: control (0.01% sodium nitrite), treatment 1 (0.15% radish powder and 2 h incubation), treatment 2 (0.15% radish powder and 4 h incubation), treatment 3 (0.30% radish powder and 2 h incubation), treatment 4 (0.30% radish powder and 4 h incubation), treatment 5 (0.30% celery powder and 2 h incubation), and treatment 6 (0.30% celery powder and 4 h incubation). The cooking yield, CIE a* values (redness), and total pigment levels were not significantly different (p > 0.05) between any of the alternatively cured treatments and the control. However, when 0.30% radish powder or celery powder was added to the products, the CIE b* values increased significantly (p < 0.05) with incubation time. At the same vegetable concentration, the nitrite content, nitrosyl hemochrome, and curing efficiency also increased significantly (p < 0.05) as the incubation time increased from 2 to 4 h, regardless of the types of vegetable powder. Among the meat products cured with radish powder, treatment 4 showed the highest increase in residual nitrite content, nitrosyl hemochrome content, and curing efficiency, but showed decreased lipid oxidation. Our results suggest that increased concentrations of radish powder and longer incubation times would be more suitable for producing alternatively cured meat products comparable to traditionally cured products treated with synthetic nitrite.

Jeupjang like salted soybean paste with vegetable is the Korean traditional side order eating at table. Bibliographical studies on the Jeupjang in historic books such as Jeungbo-Sanlim-Keongjae(Re-edition of agriculture economic), Imwon- Keongjae Ji(Book of country economic) and Keuhap-Chongseo(Handbook of household) described the Korean food in the 18 century carried out. In addition, investigation and analytical studies on various home-made Jeupjang in present was accomplished. Jeupjangs were classified into three types according to variety preparing methods. Three types were fermented soybean paste (Doenjang) type using traditional Meju(soybean cake stater) for Jeupjang, salted pickle (Jangachi) type buried cucumber and eggplant into soybean paste or soysauce (Kanjang), and salted sauer kraut (Kimchii) type prepared vegetable in Jeupjang-Meju mash. The procedures for producing Jeupjang were Jeupjang-Meju making, and mixing vegetable with Meju powder into brine. At last process was fermented in horse wastes or grasses for 7-14 days. But manufacturing methods of Jeupjang before the 18 century were different in present. Nowadays glutinous rice, red pepper powder and various vegetable were used for domestic Jeupjang.

This study was undertaken to classify Enterobacter sakazakii isolates from 13 powdered infant formula products, 25 powdered weaning diet products, and 33 weaning diet ingredients on polymerse chain reaction (PCR) methods. The numbers of the isolates from 1 powdered infant formula product, 7 powdered weaning diet products, and 6 weaning diet ingredients were 1, 14, and 8, respectively. The contaminated ingredients were 1 rice powder, 2 millet powders, 2 vegetable powders, and 1 fruit and vegetable premix. PCR with the primer of repetitive extragenic palindromic element (REP-PCR) and random amplification of polymorphic DNA(RAPD) were effective in discriminating among the isolates, but tRNA-PCR and PCR with the primer of l6S-23S internal transcribed spacer (ITS-PCR) were not. Some of E. sakazakii isolates from vegetable powders, fruit and vegetable premix, and millets powders were classified into the clonal groups based on the DNA patterns in the REP-PCR and RAPD analysis. A close genetic relationship among the isolates from some of the powdered weaning diet products and the rice powder was also detected in the cluster analysis based on the DNA patterns in RAPD.

Buckwheat leaves and young parts of the plant are consumed as a vegetable in certain countries. The quality characteristics of Sulgidduk withadded buckwheat vegetable powder(BVP)(0, 0.2, 0.5, 1.0, 1.5% w/w) were assessed in this study. Weobtained the following results: The water contents of Sulgidduk on the first day evidenced no differences according to the ratio of BVP addition, whereas the water contents of Sulgidduk decreased with increasing storage time and increasing amounts of added BVP. As the amount of BVP increased, both the L value(Lightness) and the a value(Redness) decreased, whereas the b value(Yellowness) increased. In terms of the mechanical texture characteristics, the hardness of the Sulgidduk increased with addition of both 0% and 0.5% BVP, with increases in storage time. The springiness of Sulgidduk was reduced as the quantities of BVP increased. We detected no significant differences in the chewiness of Sulgidduk according to the ratio of BVP addition. Also, the chewiness of Sulgidduk increased with BVP additions of 0% and 0.2% with increases in storage time, whereas no differences were detected in the group to which 0.5% BVP was added. The cohesiveness of the Sulgidduk decreased with increases in BVP and storage time. In our sensory evaluation of the color and flavor characteristics, the optimal quality was reported in conjunction with the Sulgidduk to which 1.0% and 1.5% BVP was added(p<0.05), whereas we noted no significant differences in texture and taste(sweetness) according to the ratio of BVP addition. Sulgidduk with 1% of BVP evidenced the best characteristics in our overall sensory evaluation.

This work aimed to prove the feasibility of NIR spectroscopy to detect vegetable protein isolates (soy, pea and wheat) in milk powder. Two hundred and thirty-nine samples of genuine and adulterated milk powder (NIZO, Ede, NL) were analysed by NIRS using an InfraAlyzer 500 (Bran+Luebbe). NIR spectra were collected at room temperature, and data were processed by using Sesame Software (Bran+Luebbe). Separated calibrations for each non-milk protein added, in the range of 0-5%, were calculated. NIR data were processed by using Sesame Software (Bran+Luebbe). Prediction and validation were made by using a set of samples not included into the calibration set. The best calibrations were obtained by the PLSR. The type of data pre-treatment (normalisation, 1$\^$st/ derivative, etc..) was chosen to optimize the calibration parameters. NIRS technique was able to predict with good accuracy the percentage of each vegetable protein added to milk powder (soy: R$^2$ 0.994, SEE 0.193, SEcv 0.301, RMSEPall 0.148; pea: R$^2$ 0.997, SEE 0.1498, SEcv 0.207, RMSEPall 0.148, wheat: R$^2$ 0.997, SEE 0.1418, SEcv 0.335, RMSEPall 0.149). Prediction results were compared to those obtained using other two techniques: capillary electrophoresis and competitive ELISA. On the basis of the known true values of non-vegetable protein contents, the NIRS was able to determine more accurately than the other two techniques the percentage of adulteration in the analysed samples.
