Myrtle also called ba dimethoate or pull son, for the myrtle family of fruit trees myrtle. The guavas is very soft, fleshy rich gravy, taste sweet, flavor close to pears and Taiwan QingZao between. Myrtle is a kind of adaptive strong tropical fruit trees. Guava juice to make all kinds of beverages and he already popular products. The myrtle fruit storage life is short, and postharvest dry serious, hardness fell rapidly, highly resistant to shipping. This paper studies the liquid immersion type quick-frozen guava juice processing technology, and through orthogonal experiment design research the frozen technological parameters and time of zein films guava juice frozen liquid immersion type influence of quality. The results of the study indicate that: when liquid immersion type quick-frozen guava juice processing technology was settled, quick-frozen temperature for - 30 ℃, quick-frozen time of 20 minutes for 45 days of zein films time, quick-frozen guava juice of the best quality.
