Origin of guava juice
This fruit originated in Central and South America. This fruit is an integral part of Mexican and other Central American cuisines. Mexicans tribes have long been using guava as a traditional treatment for diarrhea and dysentery. The Spanish and Portuguese colonizers brought the fruit back to Europe, and from there, disseminated it throughout the world. Today, it is popularly grown in tropical regions around the world.
Guava juice has several health benefits. One cup of guava juice can give you:
Despite its sugar content, it is effective in regulating blood sugar. It also helps in keeping cholesterol, triglycerides, and LDLc down while increasing the HDLc levels. Guava has anti-oxidative and anti-inflammatory properties because of its high levels of vitamin C, flavonoids, and polyphenols. This fruit juice also contains carotenoids, vitamin A, calcium, and iron in decent quantities. Regularly consuming guava can increase the bioavailability of iron among vegetarians.
Most guava produced is consumed fresh. Guava juices can be either clarified or cloudy. It is not common to use many enzymes to promote either clarification or cloudiness. However, they may contain pectinases, arabinose, and cellulase.
The commercial production begins with the selection of ripe guavas without any bruising. The fruits, once crushed, undergo enzyme treatment and then centrifugation for removing particles. The juice is then filtered and pasteurized to get rid of bacteria. After, the juice is either packaged or sent off for further processing to condense it into concentrates. The juice may also be freeze dried, spray dried, or tunnel dried to make it into flakes or powder.
Guava juice can be made fresh at home or store-bought. Freshly squeezed guava juice may be stored in the refrigerator for up to 48 hours. Commercially produced pasteurized juice can last for up to three months, as long as it is kept unopened.
