This study was carried out to investigate the effects of different types of $\beta$-cyclodextrin ($\beta$-CD) treatments on chemical and sensory characteristics of cholesterol-reduced cream cheese. The cholesterol removal rates were 92.0% in cream cheese treated by powder $\beta$-CD, and 82.6% in cream cheese treated by crosslinked $\beta$-CD. Amounts of short-chain fatty acid and free amino acids were significantly lower in cream cheese made by crosslinked $\beta$-CD-treated milk, especially after 2 weeks storage, compared with those of no $\beta$-CD-treated control and cream cheese made by powder $\beta$-CD treated milk. Among rheological properties, cohesiveness was significantly higher, and gumminess in cream cheese made by crosslinked $\beta$-CD-treated milk was slightly lower than others. In sensory analysis, no difference was found in texture among treatments, while bitterness was lower in the early stage of storage, and overall quality was higher score, in cream cheese made by crosslinked $\beta$-CD-treated cream at 3 and 4 week storage, compared with those in control and powder $\beta$-CD-treated group. The present study indicated that crosslinked $\beta$-CD treatment resulted in an efficient cholesterol removal rate over 80% and a deceleration of ripening, which may provide a longer shelf life without significant adverse effects in chemical and sensory properties.

The objective of this study was to isolate and characterize lactic acid bacteria (LAB) exhibiting cholesterol-lowering activity from the Korean traditional fermented food, kimchi. The previously isolated LAB strains were assessed for cholesterol-lowering efficacy in the presence of 0.1% cholesterol. All LAB strains tested in this study were able to assimilate cholesterol at varying levels, ranging from 35.0 to 99.4%. Among them, the Lactobacillus plantarum FMB 31 strain exhibited the highest cholesterol-lowering effect with 99.4% cholesterol removal efficiency. The strain was stable in the presence of acid, bile, and salt stress, and showed high adherence on HT-29 cells, a human colon line. In addition, the LAB strain showed no pathogenic properties such as the production of hemolysin and biogenic amines. Thus, this study suggests that the L. plantarum FMB 31 strain isolated from kimchi can be a potential source of probiotic products with strong cholesterol-lowering effect.

Cholesterol granuloma of frontal bone is a rare disease which usually occurs at the lateral part of the supraorbital ridge. This expanding lesion grows slowly and extends into the orbit and anterior cranial fossa. The most common symptom is proptosis. This granuloma is composed of a granulomatous reaction surrounding cholesterol crystals. Surgical treatment involves aspiration of contents and stripping or curettage of the lining which is highly successful. We experienced a case of cholesterol granuloma of frontal bone with huge intracranial extension, which was cured by surgical removal. The clinical features, radiologic, and pathologic finding were discussed and the pertinent literatures were reviewed.

This study was to identify and quantify the flavor compounds in cream cheese and cholesterol-removed cream cheese made from whole milk powder stored at $7^{\circ}C$ for 4 wk. Flavor compounds of cream cheese were identified using gas chromatography mass spectroscopy and quantified by gas chromatography. The tentatively identified flavor compounds were mainly eight from fatty acids in cream cheese made from whole milk powder (CCWMP) and nine from fatty acids in cholesterol-removed cream cheese made from whole milk powder (CRCCWMP). In quantitative analysis of the flavor compounds, most of the volatile compounds were slightly increased during storage. N-Decanoic acid was produced only in CCWMP. On the basis of the results, it was concluded that the quality and quantity of flavor compounds in CCWMP and CRCCWMP have almost no adverse effects in comparison with that of whole milk-made cream cheese.

This study was aimed to compare the texture and sensory properties of Cream cheese and cholesterol-removed Cream cheese made from the whole milk powder (CRWMP) during storage at $7^{\circ}C$ for 4 wk. The cholesterol reduction by crosslinked ${\beta}$-CD was about 92% in CRWMP. In texture studies, hardness, gumminess, and chewiness had increased during the storage period of 4 wk in both cheeses, irrespective of treatment. In the sensory properties, cooked milk flavor was found to have decreased, whereas sourness had increased with increasing storage period of 4 wk in whole milk powder Cream cheese. On the basis of our results, we conclude that the cholesterol removal in CRWMP does not cause any adverse effect on the texture and sensory properties of Cream cheese made with whole milk powder.

This study was carried out to find a cholesterol removal rate, flavor development, and bitter amino acid productions in Cheddar cheese treated with -cyclodextrin ($\beta$-CD): l) Control (no homogenization, no $\beta$-CD), and 2) Milk treatment (1000 psi milk homogenization, 1 % $\beta$-CD). The cholesterol removal of the cheese were 79.3%. The production of short-chain free fatty acids (FF A) increased with a ripening time in both control and milk treated cheese. The releasing quantity of short-chain FFA was higher din milk treated cheese than control at 5 and 7 mo ripening. Not much difference was found in neutral volatile compounds production between samples. In bitter-tasted amino acids, milk treatment group produced much higher than control. In sensory analysis, texture score of control Cheddar cheese significantly increased, however, that in cholesterol-reduced cheese decreased dramatically with ripening time.

The objective of the present study was to compare the chemical and sensory properties of regular cream cheese (control) and cholesterol-reduced cream cheese manufactured using crosslinked ${\beta}$-cyclodextrin (${\beta}$-CD) or powdered ${\beta}$-CD. Crosslinked ${\beta}$-CD was made using adipic acid. The composition of cream cheese treated by the crosslinked ${\beta}$-CD was similar to the regular cream cheese. Approximately 91% of cholesterol-reduction was observed in the cheeses that were treated using ${\beta}$-CD, which was not significantly different between powdered vs. crosslinked ${\beta}$-CD treatments. Total amount of short-chain free fatty acids was significantly lower in both ${\beta}$-CD-treated cheeses than in the control cheese throughout the storage. The cheeses made by ${\beta}$-CD-treated cream produced much lower amounts of individual free amino acids than the control in all periods. Most rheological characteristics, except cohesiveness, decreased dramatically in the control compared with the cholesterol-reduced cream cheeses. In sensory attributes, both wateryness and spreadability in ${\beta}$-CD-treated cheeses were significantly higher than in the control during 8 wk storage. Sensory scores for sourness increased significantly in the control from 4 to 8 wk storage, however, those in the cream cheese made by crosslinked-${\beta}$-CD treated cream increased slowly during 8 wk storage, which was shown in the control during a 4 wk period. Therefore, the present study showed the possibility of cholesterol-reduced cream cheese manufacture.

Cholesterol gallstones are a digestive disease of high prevalence that has many risk factors; for this reason, research has focused mainly on how to prevent it rather than how to treat it. Many molecules of the hepatic, bile and intestinal systems are involved in the pathophysiology of this disease, making it very difficult to find a therapeutic target. The pharmacological treatment is limited, so when gallstones generate symptoms, medical treatment indicates gallbladder removal. Ursodeoxycholic acid is used to dissolve cholesterol stones, and ezetimibe and statins are other drugs with possible applications in the treatment of this disease. Given the small number of drugs that have been developed for treating this disease, the research of natural products becomes of paramount importance. Resources such as black radish, glucosinolates, fenugreek, capsaicin, curcumin, garlic, and onion, have all shown significant effects in the prevention and treatment of cholesterol gallstones. In this review, we made a synthesis of the scientific reports that deal with these natural products and that can serve as antecedents for finding a way to treat the most common disease of the gallbladder.

Cardiovascular and cerebrovascular diseases seriously harm human health, and Bifidobacterium is the most beneficial probiotic in the gastrointestinal tract of humans. This work aimed to screen cholesterol-lowering Bifidobacterium from Guizhou Xiang Pig and evaluate its tolerance to oxygen, acid, and bile. Twenty-seven aerotolerant strains with similar colony to Bifidobacterium were isolated through incubation at 37℃ in 20% (v/v) CO₂-80% (v/v) atmospheric air by using Mupirocin lithium modified MRS agar medium, modified PTYG with added CaCO₃, and modified PTYG supplemented with X-gal. Ten strains with cholesterol-lowering rates above 20% (w/w) were used for further screening. The selected strains’ tolerance to acid and bile was then determined. A combination of colony and cell morphology, physiological, and biochemical experiments, as well as 16S rRNA gene-sequence analysis, was performed. Results suggested that BZ25 with excellent characteristics of high cholesterol-removal rate of 36.32% (w/w), as well as tolerance to acid and bile, was identified as Bifidobacterium animalis subsp. lactis. To further evaluate Bifidobacterium BZ25’s growth characteristic and tolerance to oxygen, culture experiments were performed in liquid medium and an agar plate. Findings suggested that BZ25 grew well both in environmental 20% (v/v) CO₂-80% (v/v) atmospheric air and in 100% atmospheric air because BZ25 reached an absorbance of 1.185 at 600 nm in 100% atmospheric air. Moreover, BZ25 was aerotolerant and can grow in an agar medium under the environmental condition of 100% atmospheric air. This study can lay a preliminary foundation for the potential industrial applications of BZ25.

We recently reported that a water extract of laurel or turmeric, 1,8-cineole enriched fractions, showed hypolipidemic activity in the zebrafish model. Therefore, the present study investigated the cineole's anti-oxidant and anti-inflammatory activities in lipoprotein metabolism in vitro and in vivo. Cineole had inhibitory effects on cupric ion-mediated oxidation of lipoproteins in general, while simultaneously enhancing ferric ion removal ability in high-density lipoprotein (HDL). Hypercholesterolemia was induced in zebrafish using cholesterol-feeding treatment, 4% cholesterol, for 3 weeks. After feeding with or without the addition of cineole, the results revealed that cineole possessed lipid-lowering and anti-inflammatory activities in hypercholesterolemic zebrafish. In addition, serum amyloid A and interleukin-6 levels were lowered and lipid accumulation was decreased in the liver. Conclusively, 1,8-cineole was found to have anti-oxidant activities in lipoprotein metabolism both in vitro and in vivo with simultaneous reduction of lipid accumulation in the liver of zebrafish.
