Chiffon cakes were prepared using various concentrations of aloe gel to develop functional baking procedures. The quality characteristics of chiffon cakes prepared after addition of 20%, 40%, or 60% (w/w) aloe gel, substituting for the same levels of wheat flour, were investigated. No significant weight difference between cakes was observed. The height of cakes containing aloe gel was significantly greater than that of control cakes. The baking loss rate (BLR) of aloe gel decreased as the amount of gel increased, and cakes prepared using 60% (w/w) aloe gel had the lowest BLR. Moisture contents of cakes prepared using aloe gel were higher than that of control cakes. Cakes with 60% (w/w) aloe gel had the highest moisture content. The pore size of cakes with 60% (w/w) aloe gel was the smallest of all groups. Crumb color became whiter as the proportion of aloe gel increased. Lightness (L value) of control cake was lower than that of cake containing aloe gel. Redness (a value) of aloe chiffon cakes increased as the proportion of aloe gel rose. Yellowness (b value) of cakes with 40% (w/w) aloe gel was significantly higher than that of the control group. Other cakes showed no difference in b value compared with control cake. Hardness in all cakes prepared with aloe gel was significantly lower than that of the control group. Adhesiveness of control cake was significantly lower than that of other cakes. No significant between-group difference in springiness was observed. The cohesiveness of cakes with 40% (w/w) aloe gel was significantly lower than that of the control group and that of cakes with 20% (w/w) aloe gel. The gumminess and chewiness of control cakes were significantly higher than those of other cakes. The yellowness of cake with 60% (w/w) aloe gel was significantly lower than that of the other groups. Pore size decreased after the addition of aloe gel. There was no significant difference in appearance among cakes thus, all cakes were acceptable to potential consumers. Although no perceptible difference in aloe odor was evident, cakes with 60% (w/w) aloe gel scored significantly lower in flavor acceptance compared with other cakes. No significant between-cake difference in taste acceptance, perceived moisture level, or texture acceptability was observed. Cakes with 40% and 60% (both w/w) aloe gel were of significantly higher density than other cakes. Overall, the acceptability of cakes with 60% (w/w) aloe gel was lower than that of other cakes. Ultimately, the results indicated that quality can be enhanced by adding less than 40% (w/w) aloe gel to chiffon cakes as a substitute for wheat flour.

For the scientific approaches and quality control of aloe wine as fundamental studies of industrialization and quality improvement, change of barbaloin content during the fermentation period and various characteristics of aloe wine were investigated. Alcohol of 6.35, 9.6%, and 11.3% in the 0.5% concentration of aloe powder was produced from 15%, 20%, and 25% addition of sugar in the wine mash, respectively, As the content of aloe powder is increased, production of alcohol was slightly decreased, indicating aloe powder might contain antimicrobial activity. The content of barbaloin in the 0.5% concentration of aloe powder was 4.2 mg/ml, 4.6 mg/ml and 2.21 mg/ml after 7, 10 and 30 day, respectively. The tasty characteristics of aloe wine brewed with aloe powder of 1.5% and 2.0% were most acceptable to the sensory panels.

This study investigated the effects on the quality characteristics of the korean steamed rice cake, Seolgiddok of the addition of aloe powder at 0%, 1.5%, 3.0%, 4.5% and 6.0% and 4-days storage. The moisture content of the control 0% aloe, steamed rice cake was 47.76%, and steadily decreased with increasing powder addition to the lowest of 37.38% for the cake with 6.0% added. The moisture content was decreased with extending storage time in both the control and powder-added groups. The cohesiveness, springiness, adhesiveness, gumminess and chewiness of the cake tended to decrease with increasing powder content, while the hardness increased with both increasing powder content and extending storage time. The Hunter color value L in the chromaticity of the cake was significantly decreased with increasing powder addition. The a value of the control, 0% aloe steamed cake was -0.86, but became positive with red color with increasing powder content, The b value was significantly increased with increasing powder content. The powder addition inhibited the increase in bacteria number. The sensory characteristics of the cake. such as color, aloe flavor and taste, and bitterness were increased with increasing powder content, while the moist and soft feeling of the cake were more highly evaluated at lower powder content. The overall taste was judged to be best for the sample with 3% added powder. Accordingly, it was expected that a highly functional and healthy product with improved quality might be developed by the addition of aloe powder to the Korean steamed cake, Seolgiddok.

Aloe vera (Aloe barbadensis Miller) has been used since ancient times to improve various skin diseases such as burns, wounds, and eczema. It has been reported that Aloe vera contains vitamin, enzyme, mineral, sugar, phenolic compound, fatty acid and amino acid. Aloe vera changes its color from green to red under the extreme thermal and arid climate to protect itself. These morphological changes induce variation of composition such as increasing of aloe-emodin content. Aloe-emodin is one of the major anthraquinone in aloe family plants. Since aloe-emodin contains a polyphenolic structure, this compound may be responsible for the reported antioxidant and anti-inflammatory effects of aloe. However, there is no research on the process of increasing the compounds of Aloe vera. Therefore, the purpose of this study is to develop a pink aloe manufacturing process that increases the aloe-emodin content and enhances the antioxidant and anti-inflammatory activities of aloe. As a result of heating aloe under appropriate conditions, pink aloe increased aloe-emodin content compared to general aloe, and exhibited effects such as increasing antioxidant activity, inhibiting NO production, and promoting cell regeneration. Through this study, the applicability of pink aloe as a new anti-aging material in the cosmetic field was confirmed.

With extracted Aloe vera and Aloe arborescens, anti-inflammatory effect was examined in phosphatidic acid-stimulated Raw 264.7 cells. Phosphatidic acid $(50\;{\mu}g/ml)$ treatment increased inflammation related 264.7 cells. The extracts of $80\;{\mu}g/ml$ concentration from Aloe arborescens reduced the expression of iNOS. Aloe vera and Aloe arborescens also reduced the expression of COX-2, it seems that anti-inflammatory effects of Aloe extracts is partly due to the inhibition of COX-2 expression by inhibiting in Raw 264.7 cells.

Recently, cases of Aloe vera induced-toxic hepatitis have been reported. However, the precise inflammatory effects of Aloe vera extract have not been clearly elucidated yet. In this study, the inflammatory effects and the mechanism of 70% ethanolic Aloe vera extract on liver were evaluated by in vitro assays using human hepatoma HepG2 cells. Cell viability was investigated using MTT assay at $0.001{\sim}100{\mu}g/mL$ of Aloe vera extract. To evaluate inflammatory effect of the Aloe vera extract, the secretion of pro-inflammatory cytokine Interleukin 8 (IL-8) and Macrophage colony-stimulating factor (M-CSF) were detected. Aloe vera extract did not induce cell death at concentrations of $0.001{\sim}100{\mu}g/mL$. However, Aloe vera extract significantly increased the IL-8 secretion by 15.7~25.8% and the M-CSF secretion by 36.6~61.5% at the same concentrations. These results indicate that Aloe vera extract shows an inflammation-related mild hepatotoxicity than a severe toxicity such as cell death and this hepatitis is mediated by the secretion of inflammatory cytokine IL-8 and M-CSF.
