Our History

The basic concept for our company Purés y Derivados de Nayarit S de RL Mi (PDN) was born in the year 2006 as we looked for a solution for the loss of the guava harvest in our region. The largest challenge we found in processing guavas was the job of extracting the small seeds that the fruit has, in a practical manner. We started with a hand extractor for apple sauce using cooked guavas and freezing the sauce that was extracted. The product was very flavorful and had a nice texture. We could also mix it with other fruits such as strawberries or blackberries which also gave it an attractive presentation.

Our next step was to design a machine that would do the work in larger quantities. By the end of 2008 we had our prototype functioning and we started construction of a small factory designed specially for processing the guava sauce. On the 1st of April of 2009 we had our inauguration with many government officials present. In the following 8 months of 2009 we processed more that 10 metric tons of guava to check all the aspects of our NEW product. This is only a small percentage of our present capacity of over 40 metric tons a year.

At present we process 3 types of products

a) Guava sauce: this is our principal product which we package raw or cooked and sell in vacuum packed bags of up to 2 Kg. This can also be mixed with other fruits.

b) ATE (chewable candies) of guava. This is sold in three presentations, natural candies, fire balls of guava or guava bars with chocolate

c) ATE guava paste (sweetened) for baking and for ice cream

All our products have the seeds extracted and are made with only top quality guavas.

We can also export fresh guavas in boxes or frozen guavas with or without seeds in bags

Food Uses for Guava

Raw guavas are eaten out-of-hand, but are preferred seeded and served sliced as dessert or in salads. More commonly, the fruit is cooked and cooking eliminates the strong odor. A standard dessert throughout Latin America and the Spanish-speaking islands of the West Indies is stewed guava shells (cascos de guayaba). Guava halves with the central seed pulp removed are strained and added to the shells while cooking to enrich the syrup. The canned product is widely sold and the shells can also be quick-frozen. They are often served with cream cheese. Sometimes guavas are canned whole or cut in half without seed removal.

Bars of thick, rich guava paste and guava cheese are staple sweets, and guava jelly is almost universally marketed. Guava juice, made by boiling sliced, unseeded guavas and straining, is used in Hawaii in punch and ice cream sodas. A clear guava juice with all the ascorbic acid and other properties undamaged by excessive heat, is made in South Africa by trimming and mincing guavas, mixing with a natural fungal enzyme (now available under various trade names), letting stand for 18 hours at 120º to 130º F (49º-54º C) and filtering. It is made into sirup for use on waffles, ice cream, puddings and in milkshakes. Guava juice and nectar are among the popular canned or bottled fruit beverages of the Caribbean area. After washing and trimming, whole guavas in syrup or sprinkled with sugar can be put into plastic bags and quick-frozen.

There are innumerable recipes for utilizing guavas in pies, cakes, puddings, sauce, ice cream, jam, butter, marmalade, chutney, relish, catsup, and other products. In India, discoloration in canned guavas has been overcome by adding 0.06% citric acid and 0.125% ascorbic acid to the sirup. For pink sherbet, French researchers recommend 2 parts of the cultivar 'Acid Speer' and 6 parts 'Stone'. For white or pale-yellow sherbet, 2 parts 'Supreme' and 4 parts 'Large White'. In South Africa, a baby-food manufacturer markets a guava-tapioca product, and a guava extract prepared from small and overripe fruits is used as an ascorbic-acid enrichment for soft drinks and various foods.

Dehydrated guavas may be reduced to a powder which can be used to flavor ice cream, confections and fruit juices, or boiled with sugar to make jelly, or utilized as pectin to make jelly of low-pectin fruits. India finds it practical to dehydrate guavas during the seasonal glut for jelly-manufacture in the off-season. In 1947, Hawaii began sea shipment of frozen guava juice and puree in 5-gallon cans to processors on the mainland of the United States. Since 1975, Brazil has been exporting large quantities of guava paste, concentrated guava pulp, and guava shells not only to the United States but to Europe, the Middle East, Africa and Japan.
Canned, frozen guava nectar is an important product in Hawaii and Puerto Rico but may be excessively gritty unless stone cells from the outer flesh and skin are reduced by use of a stone mill or removed by centrifuging.
