FR2621224A1 - Emulsion based on avocado pulp, or on other fruits and vegetables or their pulp, devices for manufacturing them and all the culinary preparations manufactured by emulsion and obtained by the said devices - Google Patents

Abstract

The present invention relates to an emulsion based on avocado pulp, or on other fruits and vegetables or their pulp, the devices for manufacturing them and all the culinary preparations manufactured by emulsion and obtained by the said devices. The emulsion according to the invention is prepared by a grinding under nitrogen. This invention makes it possible to obtain a food product of a high gustatory quality and whose preservation is effected under perfectly satisfactory conditions.

Description

 The present invention relates to an emulsion based on avocado pulp stored under nitrogen in positive cold (4 to 60C). This invention also relates to the devices used to obtain this emulsion, which devices are also applicable to other fruits and vegetables or to their pulp or to all culinary preparations made by emulsion.

 The conservation of avocado-based products has already been the subject of much research and various solutions have been recommended, in particular freezing, deep-freezing, treatments by infrared, ultraviolet or ionizing radiation.

 However, such methods have major drawbacks such as the implementation of expensive techniques, such as deep freezing, and the need to distribute in certain cases these avocado-based products by commercial circuits in negative cold.

 In addition, these avocado products thus prepared cannot be used immediately because they must first be processed for marketing.

On the other hand, the stability conferred on avocado by freezing or deep freezing disappears as soon as the state of metastable equilibrium due to the cold ceases.

 Freeze-dried avocado after freezing is difficult to rehydrate under good conditions; its stability in the anhydrous state is also not very good.

 Avocado stabilized with chemical agents and treated or not with ultraviolet or ionizing radiation is difficult to accept by the health services of many countries due to the use of certain stabilizing chemical agents not approved by these services. In addition, these chemical agents have the drawback of seriously damaging the organoleptic properties of avocado.

 The present invention overcomes these drawbacks, including those inherent in the marketing of avocado in the refrigerated circuit.

It relates primarily to the product based on vocat whose characteristics are as follows
-it is an emulsion based on avocado pulp added with a Poultry juice or a juice of another meat or a juice based on products of plant origin or a mixture of these different juices and also added different spices and culinary additives to meet the tastes of different clienteles,
-made and stored in positive cold,
-manufactured, packaged and stored under an inert atmosphere and all of these manufacturing phases are preceded by the provision of avocado pulp and other ingredients in the grinder and the placing of said grinder under vacuum.

This invention was made possible by the high speed grinding obtained by the device consisting of a composite production line
-a high speed crusher equipped with a cutting tool that can rotate from 500 to 5000 revolutions / minute, a positive cold refrigeration device, a vacuum device and a blowing device d 'nitrogen,
-a packaging machine equipped with a vacuum device and a nitrogen blowing device.

 This production line can include a third work station, in this case a transfer device placed between the high speed crusher and the vacuum packaging machine and working under an inert atmosphere.

Thus, by means of this production line including a transfer device, it is possible to carry out continuous production under an inert atmosphere and under a positive cold temperature under almost perfect working conditions.

 This production line made up of 3 interconnected workstations, respectively grinding, transfer and packaging, constitutes an invention whose major advantage is the constant preservation of the inert atmosphere and the temperature at a posirlf cold.

 This device implemented in this production line consisting of three workstations and described in the above paragraph can also be used for the treatment of other fruits and vegetables or their pulp or of all other culinary preparations made by emulsion. .

In addition, grinding at high speed, preferably from 1000 to 2000 revolutions / minute, brings the following advantages to the avocado:
- by puncturing fatty globules contained in the avocado pulp as this has been proven by photos taken on a microscope, it helps to refine its taste,
-it produces an emulsion of incomparable creaminess,
emulsion comes in a pale green color which is very attractive commercially.

 As for nitrogen, it keeps avocado all its natural qualities without the slightest possible alteration by replacing oxygen even in the emulsion.

The same is true for other fruits and vegetables.

 For avocado pulp emulsion, the recommended weight percentages are 609 for the pulp and 40 'for the poultry juice.

 The final objective of this invention is firstly to open the refrigerated market to avocado and secondly to launch on the same market a line of natural products based on fruits or vegetables perfectly meeting the ecological aspirations of customers current.
