BACKGROUND/OBJECTIVES: Timing of almond intake during a day may result differently in the perspectives of body composition and changes of lipid profile. The current study was conducted to compare the effects of daily almond intake as a preload versus as a snack on body composition, blood lipid profile, and oxidative and inflammation indicators among young Korean adults aged 20-39 years old. SUBJECTS/METHODS: Participants were randomly assigned to one of three groups: a pre-meal almond group (PM), a snack almond group (SN) in which participants were instructed to consume 56 g of almonds either as a preload before meals or as a snack between meals, respectively, and a control group (CL) in which participants were provided high-carbohydrate iso-caloric control food. Measurements were performed at baseline, weeks 8 and 16. RESULTS: A total of 169 (M 77 / F 92) out of the 227 participants completed the study between June 2014 and June 2015 (n = 58 for PM; 55 for SN; and 56 for CL). A significant decrease in body fat mass was observed in the PM group at both weeks 8 and 16 compared with the CL. There were significant intervention effects on changes of body fat mass (P = 0.025), body fat percentages (P = 0.019), and visceral fat levels (P < 0.001). Consuming almonds as a daily snack reduced the levels of total cholesterol (P = 0.043) and low-density lipoprotein (LDL) cholesterol (P = 0.011) without changing high-density lipoprotein (HDL) cholesterol compared with the CL. CONCLUSION: Almond consumption as a preload modified body fat percentages, whereas snacking on almonds between meals improved blood lipid profiles. This trial was registered at ClinicalTrials.gov as NCT03014531.

This study was carried out to investigate changes of the lipid contents and the fatty acid composition in shank during heating time and frozen storage. 1. The total lipid contents of raw shank were about 3.57% and decreased stepwise during heating time 30, 60, 90 min and frozen storage(24hrs) The contents of neutral lipid, glycolipid and phospholipid were 70.71%, 6.36%, and 22.93% in raw shank, and neutral lipid contents were decreased, whereas Phospholipid contents were increased according to heating tide. In frozen storage, neutral lipid and glycolipid contents were increased, while phospholipid contents were decreased. 2. Lipids of shank possessed about 8 kinds of fatty acid as the constituent by gas-liquid chromatography analysis. The main fatty acids were oleic acid, palmitic acistearic acid and linoleic acid: the fatty acids of total lipids in raw shank were 43.48% of oleic acid, 23.13% of palmitic acid,12.00% of stearic acid and 6.75% of linoleic acid. Also the fatty acids were 43.32% of oleic acid, 23.26% of palmitic acid, 9.30% of stearic acid 2.15% of linoleic acid in neutral lipid, 22.63% of oleic acid, 8.44% of palmitic acid, 11.98% of stearic acid, 27.01% of linoleic acidin glycolipid, 39.38% of oleic acid, 15.89% of palmitic acid, 15.55% of stearic acid, 17.49% of linoleic acid in phospholipid. 3. The fatty acid pattern of total lipid, neutral lipid, glycolipid and phospholipid was not any changes, whereas there was a difference in the fatty acid contents: palmitic acid and stearic acid of total lipid were decreased in the 30 min and 60 min heating but increased in 90min heating, and linoleic acid of neutral lipid was increased stepwise during heating time and frozen storage. Also palmiict acid of glycolipid was increased gradually and linoleic acid in heating time 30, 60 min was higher than 90 min and frozen storage. Among fatty acids in phoapholipid, oleic acid was increased during heating time, while decreased in frozen storage, and linoleic acid was not any change but linolanic acid was increased. UFA/SFA of phospholipid was the highest when heating time was 60 min. From above results, it was found that when heating time was 60 min beneficial nutritionally, comparing with changes of fatty acid composition according to the heating time aid frozen storage.

This study examined the effect of the pine needle sap administration on serum lipid composition and liver antioxidant defense system in rats fed with high fat diet. Forty eight male Sprague-Dawley rats were divided into six groups. three control groups were fed with 5% lipid diet and three high fat groups were fed with 30% lipid diet. Each group was administered with the following pine needle sap respectively : C-0.0, 1.ml water, C-0.5, 0.ml pine needle sap and 0.ml water C-1.0, 1.ml pine needle sap : H-0.0, 1.ml water, H-0.5, 0.ml pine needle sap and 0.ml water H-1.0, 1.0ml pinus needle sap. After 4 weeks of experimental periods the level of serum obtained and serum lipid was measured respectively. The results were as follows 1. Significant low level was observed for food intake, weight gain, FER in the experimental group administered with the pine needle sap. 2. No difference of the concentration of serum triglyceride was observed out the experimental group with 5% fat diet, however out of the experimental group with 30% fat diet it was low in (H-1.0) group where 1.0ml of the pine needle sap was administrated. 3. In the experimental group with 5% fat diet the concentration of serum total cholesterol and LDL cholesterol was low, especially the hypocholesteromic effect in serum administered by the pine needle sap was significantly high in group C-1.0 where 1.0ml of pine needle sap was administered. In the high fat group provided with 30% fat when the pine needle sap was administered there was a tendency that concentration of total cholesterol and LDL cholesterol decreased however there was no difference significantly. 4. Serum GOT activity was relatively high in high fat diet group. However, when 1$m\ell$ of pine needle sap was administered the activity was lower than that of the control group in H-1.0 group and the activity level was similar with that of the high fat diet group in c-1.0 group. There was no difference of serum GPT activitives followed by the administered of pine needle sap among the experimental group. 5. Liver TBARS levels were high in general in high fat diet group, however it showed no difference when the pine needle sap with different concentration level was administered. The results of this study indicate that the pine needle sap administration was effective in decreasing the food intake and weight gain of the experimental animals in the high fat diet and also effective in decreasing the levels of serum triglyceride, total cholesterol and LDL cholesterol and GOT activities. However it was not effective to change the level of TBARS and GSH -Px activities of liver. Thus, it was found that the pine needle sap administration was effective for the improvement of serum lipid composition condition of the experimental animals in the high fat diet group but it was not effective in the antioxidant defense system of liver.

This study was carried out to evaluate the different physicochemical properties of various lipid sources in beef patties during storage for 6 months. Four groups of samples were made of beef meat patties with 22% of tallow, lard, chicken fat and 20% of palm oil. On the analysis result of physicochemical compositions, the patty has its own fatty acids composition and characteristic different from other lipids. Patty with chicken fat has the highest percentage of unsaturated fatty acid composition of 61.0% compared to the other groups of patties. Beef patty with chicken fat has 18.8% of poly unsaturated fatty acid(USFA) and beef patty with beef lipid has 1.5% of poly USFA which is the least percentage among the others. SFA/USFA ratio of beef patty with chicken lipid was 0.5 which was the least value. The composition of PUFA in beef patty with lard increased to 10.0% from 1.9% over initial value after storage for 6 months. On the contrary, the composition of PUFA in beef patty with chicken fat decreased to 9.2% from 18.8% over initial value after 6 months. Volatile free fatty acids of beef patties were evaluated with four kinds of lipid sources. Formic acid was the most as of 59$\mu\textrm{g}$/g in beef patty with tallow, acetic acid was 15$\mu\textrm{g}$/g, and heptanoic acid was 10$\mu\textrm{g}$/g at starting time of storage. However, propionic acid, butyric acid, valeric acid and caproic acid were not detected. After 6 months, formic acid decreased from 59$\mu\textrm{g}$/g to 7$\mu\textrm{g}$/g in the patty with tallow, from 12$\mu\textrm{g}$/g to non-detect level in the patty with palm oil, but two the others patties slightly increased. Volatile compounds in meat patties were reported nearly 1000 kinds of chemical compounds. Beef patty with tallow has aldehydes 5.3, alcohol 1.3, hydrocarbon 0.8, ketones 0.2, ester 0.1, furans 0.1, acid 0.04, sulfur 0.03 in peak area at starting and increased to aldehydes 8.5, alcohol 2.1, ketones 0.5, ester 1.0, furans 1.5 in peak area during the storage. But only furans was not detected after 6 months of storage. From starting to 6 months, aldehydes increased 2∼10 times, alcohol increased 2∼3 times, acids 4∼50 times and ester 9∼20 times in beef patties with pork lipid, chicken lipid and palm oil. Some volatile compounds such as alcohol, aldehydes and acids in all kinds of patties significantly increased after 6 months of storage. These increases cause oxidative rancidity taste in meat patties. These results showed that selt-life of meat patties with 4 different lipids were not over 6 months even though they were stored at -20$^{circ}C$. Therefore, they should be classified as off-grade because of oxidative rancidity. Although beef patties with tallow are currently common type, the possibility for new type of hamburg patty can be developed by applying different lipids. Finally, we found out new type of beef patty added with lard, which has the best taste and quality compared to the other common types.

The chemical composition of fish feeds(mackerel, gizzard shad, shrimp and formula feed) were analyzed and compared with those of untreated and irradiated (5 kGy) feeds, and the effects of gamma irradiation (5 kGy) and butylated hydroxyanisole (BHA, 200ppm) on feeds spoilage were investigated by determination of thiobarbituric acid (TBA) value and peroxide value for 14 days at $20^{\circ}C$, $4^{\circ}C$ or $-20^{\circ}C$. Crude protein, crude lipid, crude fiber, crude ash and nitrogen free extract were not significantly changed by gamma irradiation with the dose of 5 kGy. Immediately gamma irradiation increased the initiative oxidation of feeds as expected. But BHA was found to be greatly effective in minimizing the radiation-induced peroxidation (p<0.05). The TBA value and peroxide value increased with the elapse of the storage period. The level of lipid oxidation was increased depending on the rise in storage temperature. But the additions of BHA inhibited the lipid oxidation (p<0.05).

Dietary lipid biomarkers (fatty acids, fatty alcohols, and sterols) in adult specimens were analyzed to compare and understand the feeding ecology of the euphausiid, Euphausia pacifica, from three geographically and environmentally diverse Korean waters (Yellow Sea, East China Sea, and East Sea). Total lipid content of E. pacifica from Korean waters was about 10% dry weight (DW) with a dominance of phospholipids (>46.9% of total lipid content), which are known as membrane components. A saturated fatty acid, C16:0, a monounsaturated fatty acid, C18:1(n-9), and two polyunsaturated fatty acids, C20:5(n-3) and 22:6(n-3), were most abundant (>60% of total fatty acids) in the fatty acid composition. Some of the fatty acids showed slight differences among regions although no significant compositional changes of fatty acids were detected between these regions. Phytol, originating from the side chain of chlorophyll and indicative of active feeding on phytoplankton, was detected all samples. Trace amounts of various fatty alcohols were also detected in E. pacifica. Specifically, krill from the Yellow Sea showed relatively high amounts of longchain monounsaturated fatty alcohols (i.e. 20:1 and 22:1), generally found in herbivorous copepods. Three different kinds of sterols were detected in E. pacifica. The most dominant of these sterols was cholest-5-en-$3{\beta}$-ol (cholesterol). The lipid compositions and ratios of fatty acid trophic markers are indicative of herbivory in E. pacifica from the Yellow Sea and East Sea (mainly feeding on dinoflagellates and diatoms, respectively). The lipid compositions and ratios of fatty acid trophic markers are indicative of carnivory or omnivory in E. pacifica from the East China Sea, mainly feeding on microzooplankton such as protozoa. In conclusion, lipid biomarkers provide useful information about krill feeding type. However, further analyses and experiments (i.e. gut content analysis, in situ grazing experiment, etc.) are needed to better understand the feeding ecology of E. pacifica in various marine environments.
