Abstract
The possibility of producing new untraditional garlic juice prepared from different newly clonal genotype of Spanish garlic cultivars (Kaha 211, 221 and 341) was tried. Environmental adaptation, chemical and physical properties for these new genotypes as well as specified properties of bulbing and yield quality were considered. Addition of different natural anti-browning agents as well as retained sulfur compounds were also concerned to prevent browning and preserved pungency. The effect of storage at ambient temperature (25±5°C) for 60 days was investigated. Garlic juice (genotype Kaha 211 and 341) had the lowest amount of total acidity when preserved in solution (0.3% cystein 0.3% citric acid + 0.1% ascorbic acid) than the other treatments. Total pungency was concentrated in garlic juice (genotype Kaha 221) when preserved in the same solution. This treatment could protect the pungency of garlic juice before and after storage up to 60 days. Garlic juice (genotype Kaha 211) preserved with solution (1.0% NaCI, 0.5% citric acid, 2.0% soybean oil and 0.1% cystein), had a good color index compared with the other treatments. Meanwhile, garlic juice (genotype, Kaha 341) preserved in solution (0.3% cysteine i 0.3% citric acid + 0.1 ascorbic acid) retained a sharp clearly juice. Any colony forming unit of either total bacterial count or fungi were not detected during 60 days of storage especially in genotypes Kaha 211 and 221. The new clonal genotypes (Kaha 211, 221 and 341) of Spanish garlic cultivars could be used to produce a good quality of garlic juices and added values if compared with other old varieties. So, the research recommend and encourage these new genotypes for cultivating in Egypt and may be especially, used for exportation.
