Gelatin soft capsules, manufactured by the press through package(PTP) process, are widely used in the production of multivitamin dietary supplements and other health functional foods. Gelatin capsules can prevent light and air from having a direct contact with the contents in the capsule, and the nutrients inside the capsules are preserved without any loss. In the present study, on the basis of the results on the safety of gelatin capsules. The parameters investigated included degradation of the capsules before their shelf life, capsule deformation, and changes in specific nutrients. Moisture and heat in the production and storage environments of the capsules caused the gelatin to swell and attach some of the inorganic salts in the vitamin contents. Nutritional component analysis showed that B1, B5, B9, and B12 contents were decreased, while mineral elemental analysis shown calcium, chloride, and zinc compound were found to be infused into the gelatin of the capsule shell.

The previous vitamin assays in soft capsules have been performed only with capsule contents. Since some vitamins, however, could migrate into gelatin layer of the soft capsules, each vitamin of multivitamin soft capsules in the market was analyzed simultaneously in both capsule content and gelatin layer. The results showed that migrations of nicotinamide and pyridoxine hydrochloride into gelatin layer were pronounced, while those of other vitamins were negligible.

Determining the origin of the components in commercially available gelatin, a purified protein derived mostly from pig skin and bovine tissue, is a challenge, leading to concerns on the grounds of religious beliefs and health. Therefore, regular monitoring of labeling compliance by food control authorities is also necessary. In this study, we monitored the origin of gelatin capsules from 181 commercial dietary supplements that were available for purchase on the internet, using species-specific PCR assays. Fifty five products were labeled correctly, declaring that they used bovine-, fish- and plant-derived gelatin, whereas the other 126 capsules were labeled "gelatin" without specifying the origin. Gelatin in these capsules was obtained from cattle (n = 51), pigs (n = 31), or both (n = 44). Therefore, it is important to declare all of the raw materials used to produce gelatin capsules on the labels to best protect consumers' rights, religious beliefs, and health.

Gelatin is a high molecular weight polypeptide derived fro mcollgen, theprimary protein component of animal connective tissues, which include bone, skin and tendon. Gelatin is usually produced from two different sources of raw materials (skins or bones) which are processed in two ways(line or acid). According to this pretreatment, gelatin can be divided into elatin type A(acid) and B(lime). The market is essentially driven by thre demand sectors: food, harmaceuticals(capsules) and photography. Although there is some potential threat in the photography sector, the oher tow sectors are well placed for futher growth.

Stability is impaired in capsules in which there is a transfer of water vapor from capsule to the contents of the capsules. The water vapor transfer between AEA-coated capsules and corn starch, magnesium trisilicate in the closed container was examined. Experimental eguilibrium relative humidity after water vapor transfer and estimated values calculated from a formula of these substances were in close agreement with each other.

This article presents an evaluation of the effects of coating conditions on the enteric coating quality of soft gelatin capsules containing Omega-3 fatty acids. Three conditions were controlled: concentration of hydroxypropyl methylcellulose phthalate (6, 8, and 10 wt% in solution), temperature of the inlet air (32, 35, and $38^{\circ}C$), and the coating solution feed rate (7.5, 11.25, and 15.0 g/min). The transparency of the enteric coated soft gelatin capsules was evaluated by measuring the degree of whiteness of the surface using a spectrophotometer. Results showed that the most important parameter in the enteric coating process was the coating solution feed rate. As the coating solution feed rate decreased and inlet air temperature increased, the degree of whiteness of coating surfaces decreased. We also evaluated the disintegration properties of the enteric coated capsules in accordance with the Korea Health Functional Food Code.

A Softgel is an oral dosage form for medicine similar to capsules and softgel dosage form offers several advantages over other oral dosage forms, such as delivering a liquid matrix designed to solubilize and improve the oral bioavailability of a poorly soluble compound as a unit dose solid dosage form, delivering low and ultra-low doses of a compound. This study aimed to qualify a proprietary vegetable soft capsule which contains modified starch and carrageenan as capsule shell components compare to the conventional gelatin softgel. Four kinds of samples were prepared with vegetable and gelatin capsule shell, respectively. Morphology of capsule shell, mechanical strength of capsule, and hygroscopic properties were studied for comparing the quality attributes of softgel. Short-term stability against heat and moisture was also investigated in this study. Vegetable capsule shell showed better mechanical strength, physical stability and disintegration time for temperature and humidity than those of conventional gelatin capsule shell with four different filling materials used frequently as soft capsule form. Conclusively, this vegetable capsule shell polymer system can replace easily gelatin-shell systems and additionally allows encapsulation of lipid fills at high temperatures that are semisolid or solid-like at room temperature.

Solid dispersions were used to increase the dissolution rate of biphenyl dimethyl dicarboxylate (DDB) in water, with the ultimate goal of optimizing its bioavailability when incoporated into pharmaceuticals. Carriers used were Kollidon 30, Kollidon VA 64, 2-hydroxypropyl-${\beta}$-cyclodextrin (HPCD), sodium salicylate or sodium benzoate. DDB solid dispersions were prepared at drug to carrier proportions ranging from 1 : 5 to 1 : 20 (w/w) by solvent evaporation method. DDB tablets (7.5 mg) were prepared by compressing the powder mixture composed of solid dispersions, lactose, corn starch, crospovidone and magnesium stearate using a single-punch press. DDB capsules (7.5 mg) were prepared by filing the mixture into empty hard gelatin capsules (size #1). Dissolution studies of DDB from powdered solid dispersions, tablets and capsules were performed in 900 $m\ell$ of water at 100 rpm and 37$^{\circ}C$ by the paddle method. The dissolved amount was assayed by HPLC and expressed as the mean(%)of three determinations.
