  • High prices of raw materials used as media for the mushroom cultivation increased the cost of commercial production of oyster mushroom (Pleurotus ostreatus). In this study, garlic peels (Allium sativum f. pekinese) as an agricultural by-product were investigated to replace the saw dust for the bottle cultivation of oyster mushroom. Mycelial growth of oyster mushroom were examined by the extracts made from the sawdust, rice bran and garlic peels. The mycelial growth was very poor in the agar media containing the extracts of sawdust or garlic peels, but was good when those of the rice bran were added. In the polypropylene bottle experiment, the sawdust medium which ammended with minerals vitamin was essential for the production of the mushroom fruitbodies. The rice bran was considered to stimulate the mycelial growth, but not the development of basidiocarps. The garlic peel was not a factor to stimulate the production of mushroom fruitbodies, but a raw material ammended with the rice bran produced much amounts of mushroom. In this work, garlic peels ($10{\sim}70%$ v/v) added to the mixture of sawdust and rice bran (4 : 1, v/v) was considered to help the productions of mushroom fruitbodies. Based on the result, the replacement of expensive saw dust with inexpensive garlic peels was a good example to reduce production cost of the bottle cultivation of mushroom.

  • There are more than three hundred garlic peeling facilities in Korea and most of them use pressurized air for skin peeling operation. One of the major problems of using air for the peeling operation is the occurrence of excessive bruises on the flesh of peeled garlic which causes easy microbial contamination and shortening of the shelf lift. To reduce the occurrence of bruises during the peeling operation, a new type of garlic peeling system was developed which use pressurized water. In this system, high pressure water jets were used to separate garlic bulbs and to peel the skin of garlic cloves. Six commercial systems of this type had been developed and installed at several locations in Korea. The design and performance of the latest system according to three pressure levels were described in this paper. Peeling efficiency of the system was as high as $64.7\%$ in one cycle of peeling operation by three chambers installed in series. Incorporation of a sorting system based on machine vision and re-circulation of unpeeled and partially-peeled garlic enhanced peeling efficiency by additional $30\%$, resulting in total peeling efficiency of the final products of approximately $95\%$. Peeling capacity of the system was over 400 kg per hour.

  • This study was carried out to investigate the antioxidant activities, total phenol, and flavonoid contents of 70% methanol, 70% ethanol, and chloroform-methanol (CM, 2:1, v/v) extracts from garlic (Allium sativum L.) peels. Antioxidant activity was evaluated by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical and ABTS [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] radical scavenging activity, ${\beta}$-carotene bleaching assay, and ferric reducing antioxidant power. Total phenol and flavonoid were in a range of 32.59-63.05 mg CAE/g, 5.26-9.22 mg QE/g, respectively. Total phenol and flavonoid were predominant with the values of $63.05{\pm}0.20mgCAE/g$ and $9.22{\pm}0.17mgQE/g$ in 70% ethanol extract. Additionally, 70% ethanol extract also displayed the strongest antioxidant activity followed by 70% methanol extract and CM extract in all assays. These results showed that garlic peel can be used as natural antioxidant in nutraceutical preparations to prevent human diseases.
