Definitions
- the present invention relates to a bag of peeled fruits and a method of making fresh fruit bags.
- peeled fruits are distributed in different ways. For reasons of public health, consumers are increasingly encouraged to eat fruit, preferably peeled. But these exhortations do not give the expected results for many reasons related to the preparation of most of the fruits and can not be done simply in the kitchen or related to the moment of consumption (morning, dessert, breakfast, snack, aperitif, alone, with family, friends, etc.).
- peeled fruits try to meet part of this demand.
- Some forms of presentation of peeled fruits for example fruit skewers, try to create new outlets, but a disadvantage of the presentation of fresh fruits in store, regardless of the form of the stores, is their very short shelf life. which results in complex issues of inventory management, transportation and unsold processing.
- the main consumption of fruit alongside fresh fruit is in the form of canned or frozen foods or products derived from them such as compotes.
- Ready-to-use peeled fruits are mainly found in supermarkets, mainly in trays or trays.
- the fruits are then either in the form of semis with a shelf life of about two months or fruit peeled with a preservative and then their lifespan is of the order of twelve days. Peeled fruits without juice also exist but their shelf life is shorter, of the order of six to seven days.
- organoleptic qualities of the products offered are not the best because for these qualities to be developed, it is necessary that the products are mature, but at such a stage, the products are kept very little time.
- the object of the present invention is to develop a means of making and spreading fruit, ready to be consumed, by increasing their shelf life, while retaining their organoleptic qualities and allowing in particular a consumption of portions of fruit without having to peel and prepare them for consumption under conditions close to eating sweets.
- the invention relates to a bag of fruit in pieces and a process for making fruit cut into pieces, ready to be consumed.
- the bag is a tubular bag of a transparent plastic food material having, in a vacuum, flat, a rectangular shape and in which are grouped fruit pieces without juice and not under vacuum,
- the process of producing fruit cut into pieces in a bag is characterized in that
- a tubular bag of section corresponding to that of the regular pieces of fruit is made of a food plastic material that is impervious to air and water vapor, and that allows the treatment with microwaves,
- the sealed tubular bag is subjected to a brief heat treatment by microwaves, sufficient to block microbial growth and inhibit enzymes, and
- the bag is cooled to keep and transport cold.
- fruit pieces means pieces of fruit of the same type or of the same fruit or a mixture of pieces from different fruits.
- the fruits are packaged in a particularly advantageous manner in portions, for example individual, in a tubular bag-shaped envelope totally or partially, plastic food, airtight and water vapor.
- the tubular shape of the bag allows stacking of the pieces inside the bag by limiting their overlap, which considerably improves the homogeneity of the reception of the electromagnetic energy in the microwave oven, resulting in an excellent homogeneity of the temperature during microwave treatment.
- infrared emission is detected by the fruit pieces treated in the bag through the wall, to verify that the required temperature has been obtained in the oven for each of the pieces and in the opposite case, the bag is evacuated as being defective.
- the detection is made using an infrared sensor (infrared thermometer) which, from the radiation emitted by each of the pieces of fruit, transforms the radiation signal into a temperature value compared to a limit to verify that the prescribed temperature has been achieved.
- infrared sensor infrared thermometer
- This temperature limit may be a range of temperatures in which the processing temperature of the piece of fruit should be located. It can also be a minimum temperature or a maximum temperature.
- the bag made for example polypropylene offers the advantage of being brilliant which highlights the bagged products.
- the rigid packaging thanks to its structure and to the pieces of fruit which it contains, makes it possible to eat peeled fruits without dirtying the hands and that with one hand holding the sachet.
- the bag is easy to open without the need for a tool (knife, chisel or other) thanks to the notch that locally weakens the weld from the outside.
- the packaging can be rolled on itself to enclose the remains of fruits or juices without contaminating the environment.
- the bag is made from at least one ply of plastic material, folded, welded along a longitudinal edge and a bottom formed by a transverse weld, the bag being sealed after filling, by another transverse weld.
- the bag is made by two superimposed sheets whose longitudinal edges are welded, the bottom being formed by a transverse weld and the sealed closure being formed by a transverse weld.
- the bag is provided with impressions and decorations on its faces leaving a transparent window to see the products highlighted by the decoration of the bag.
- the process according to the invention makes it possible to package peeled fruits cut into ready-to-eat pieces which can be preserved for three weeks without significantly losing their organoleptic characteristics and the bag can remain several hours at room temperature before consumption.
- the free volume of the bag around the fruit pieces is reduced before being sealed and, upstream of the heat treatment, so as to absorb the increase in volume of the gases inside the bag during the sudden rise in temperature produced by the heat treatment.
- the packaging or the bag can thus withstand this sudden increase in volume without requiring complex complementary means such as valves, which would also change the appearance of the bag.
- At least one of the longitudinal welds is weakened by a notch near the closure seal of the bag to allow tearing the bag there and open it.
- the method is characterized in that:
- the fruit pieces are packaged in tubular bags of a volume much larger than the volume of the pieces of fruit to be received,
- the bag is sealed after having considerably reduced the internal free volume of the bag
- the bag is subjected to a rapid thermal treatment by microwaves to block the microbial growth and inhibit the enzymes, the bag is cooled,
- the portion of the bag located beyond the intermediate seam and which does not contain fruit pieces is cut.
- the pieces of fruit in the other part of the bag hold each other, which gives a good presentation to the product obtained and favors consumption directly without having to touch the pieces of fruit.
- the pieces of fruit not being bathed in juice look like pieces of fresh fruit which they have retained the organoleptic properties.
- the acidity of the fruit is determined in pieces and if the pH is above 4.5, the fruit pieces are acidified by immersing them in a food acid and then draining them.
- FIG. 1 is a plan view of a tabular bag according to the invention
- FIG. 2A is a diagrammatic section of two sheets intended to be assembled to form a bag
- FIG. 2B represents in section the bag made by the longitudinal welds of the two sheets of FIG. 2A,
- FIG. 3A is a U-shaped band of material for forming a bag
- FIG. 3B represents the assembly by welding of the two edges of the folded strip of FIG. 3A
- FIG. 3C is a variant of the bag of FIG. 3B with a second longitudinal weld covering the fold
- FIG. 4 is a block diagram of the production process according to the invention.
- FIG. 5 is a block diagram of a variant of the production method according to FIG. 4,
- FIGS. 6A, 6B, 6C, 6D show the evolution of a tubular packaging of pieces of fruit peeled during the process according to the invention.
- FIG. 1 shows a packaging of fruit pieces according to the invention, it is produced by a bag 100 made of a food plastic material, of tubular shape, that is to say of length (L) that is relatively large compared to at its width (i).
- the section is chosen according to the size of the pieces of fruit (MF) so that they, cut, are distributed regularly in the bag in the form of a stack.
- the bag has a certain longitudinal rigidity resulting from its material and its structure. Indeed, in top view the bag has a rectangular shape bordered on each side by a wide weld 101, 102 and a bottom 103 also welded.
- the fourth weld 106 made after filling is wide so that the longitudinal welds 101, 102 and their cooperation with the transverse welds 103, 106 at the ends give the bag a certain rigidity reinforced by filling with the pieces of fruit (MF).
- At least one of the two longitudinal welds is weakened locally by a notch 107 to initiate the tearing of the bag under the transverse weld 106 closing the opening 105 of the bag beyond the pieces of fruit.
- the bag 100 can thus be practically like a stick.
- the pieces of fruit (MF) contained in the volume 104 of the bag 100 are treated after closing the bag by passing through a microwave oven for a short period.
- the bag 100 may comprise a decorative covering with a decorated / printed back and on the front face of the decorated / printed areas forming surfaces 108, 109 more or less opaque with a window 1 10 revealing the content and highlighting it.
- 100C are schematically shown in section in Figures 2A, 2B, and 3A, 3B, 3C.
- the bag 100A is obtained by assembling two longitudinally welded plies or ribbons 201, 202
- the bag 100B is obtained from a strip 300 of double width, folded in U and welded longitudinally by a weld 303 at the two edges of the folded portions 301, 302 of this U-shaped section.
- the bag 100C produced at From a folded U-band is nevertheless welded both along the two edges and along the fold 304 ( Figure 3C) to stiffen its structure by two longitudinal welds, parallel.
- the packaging bags 100, 100A, 100B, 100C are tubular with a flattened section for reasons of treatment and presentation of the products, of the modes of consumption which they must suggest and because of the volume of air which necessarily remains around the pieces of fruit (MF) according to their shape or their fragility or other reason of conditioning.
- MF pieces of fruit
- the tubular presentation of the bags and their contents facilitates consumption in the manner of a treat, without the need for plates or cutlery and as the pieces do not bathe in juice, they are not likely to stain.
- the maximum volume of the bag is chosen to absorb the expansion of the air passing through the microwave oven; as the case may be, the final volume of the sachet at the end of the treatment will be reduced by an intermediate seam allowing the fruit pieces to be grouped together in one part of the sachet to ensure their hold, presentation qualities and good disposition for their use. consumption and holding for grouping and packaging of bags for transport and sale,
- the material of the bags is completely transparent or alternatively with a window 1 10 showing part of the products.
- the material of the sachets 100, 100A, 100B, 100C is, for example polypropylene, which has the advantage of having a glossy appearance, enhancing the products and fulfilling the conditions imposed on food packaging products.
- the material may also be a fully or partially transparent food complex.
- the filling of the bags is done with weighed batches of fruit pieces to have a substantially identical quantity of a sachet to another.
- the bag has a length of 180 to 230 mm and a flat width of 50 to 60 mm.
- the welds preferably have a width of 8 to 10 mm.
- the material used for the sachet is polypropylene with a thickness of 50 ⁇ .
- the load of pieces of fruit is of the order of 80 g.
- the fruit packaging mode according to the invention makes it possible to minimize the mass of waste produced because the fruits are consumed practically without waste and only the empty bag which corresponds to a weight of material of approximately 1 to 2 g fruit mass of 80 g.
- Figure 4 shows the different steps of the method according to the invention for the packaging of MF fruit pieces for portion consumption without having to peel or prepare the fruit.
- the method consists of different steps performed automatically by a non-detailed facility receiving the fruit packaging information, such as the nature of the fruit, the packaged quantity, the weight and other parameters necessary for the microwave heat treatment.
- the method can also be implemented semi-automatically, some operations being done manually and others automatically.
- fresh fruits (FF) are cleaned (1 1), that is to say, they are peeled and then washed and then cut into pieces. regular pieces (12) of dimensions and shapes chosen according to the nature of the fruits.
- the cut-up fruits are subjected to an acidity analysis (2) during which the acidity of the fruits thus prepared is determined. This measurement is done continuously on pieces taken at random and at a frequency depending on the nature of the fruits or lots of fruits.
- the fruit pieces are directed to an acid treatment stage (3) or directly to the conditioning stage (4).
- Fruit pieces with too low acidity are subjected to acid treatment.
- a food acid bath preferably a solution of citric acid or ascorbic acid and allowed to remain for a short period of time, for example the order of 10 minutes.
- the fruit pieces are extracted from the bath and allowed to drain.
- the acidity control (2) shows that the acidity of the fruit pieces is sufficient, that is to say if their pH is less than 4.5, they are not subjected to an acid treatment (3) and they are conditioned directly.
- Pieces of fruit arriving directly or those coming from acid treatment, drained, are grouped in batches, weighed to be packaged in tubular bags; thus the pieces of fruit are more or less aligned in the tubular part.
- the packaging is made by dry bagging (41) without adding any liquid in food plastic bags, airtight and water vapor.
- the material of the bags must allow a brief passage in a microwave oven, that is to say that the material must not release any solvent or plastic component.
- the maximum volume of the bag is important compared to the volume of the pieces of fruit.
- the air volume of the bag is reduced (42) to a minimum, without crushing or compressing the pieces of fruit and then seal the tube. This volume reduction can be done by suction without creating a vacuum in the bag.
- the maximum volume of the tubular bag is defined according to the volume of air that remains around the pieces of fruit.
- the bagged products are subjected to a preservative treatment (5).
- the bags are exposed to microwave radiation, rapidly applying a brief rise in temperature.
- This heat treatment (5) is comparable to a pasteurization, nevertheless made dry, of a duration of the order of 20 to 40 seconds.
- the parameters of the short heat treatment depend on the nature of the fruits and the mass of the packaging. These parameters are determined by tests.
- the purpose of the heat treatment is to block the microbial growth and to inhibit the enzymes of the fruits in order to preserve all the qualities of the fruits, especially their organoleptic qualities.
- the rise in temperature strongly expands the air trapped in the sealed sachet with the fruit pieces and this sudden increase in volume is absorbed by the maximum volume of the sachet.
- the bag is allowed to cool (61) and after the trapped air volume is reduced and the volume is returned to normal at room temperature, the bag dimensions can be reduced (62). by performing a new weld or intermediate weld without opening the bag. The excess part of the bag can be removed.
- the bags After cooling (6), the bags are stored and transported at a temperature of less than or equal to 3-4 ° C at the points of sale. After purchase, the cold chain can be interrupted for a few hours before the consumption of products without this being a problem either for the food quality of the products or for their organoleptic qualities.
- the preservation treatment 5 is followed by a temperature control 51.
- This control is performed by an infrared thermometer which detects the infrared radiation emitted by the fruit pieces contained in the sachet. 5.
- Control is done piece by piece, the bag being transferred aligned and the pieces of fruit being aligned in the bag. This control is done through the transparent wall of the bag.
- the bag is at least transparent over the length occupied by the pieces of fruit. It may be a transparency over the entire surface of the bag; for example, the back of the bag is transparent and the front covered with an impression, a decoration, etc. It may also be a transparency limited to a longitudinal band on the bag so that all the aligned fruit pieces can be detected by the infrared thermometer (infrared sensor).
- infrared thermometer infrared sensor
- the sensor signal is compared to a threshold that verifies that each piece of fruit in the bag has been brought to the required temperature (or at a temperature within a required temperature range or above or below a threshold).
- the bag In the event that one of the fruit pieces of the bag has not undergone the required temperature rise, the bag is considered to be defective and is then evacuated (52).
- Steps 1 to 4 and 6 and 7 of the method already described above are the same in the present variant. These steps will not be described again.
- packaged batches of fruit pieces are packaged (FIG. 6A) after their draining or directly at the outlet of the acidity control (2).
- tubular bags 100 whose length (and volume) are much larger than necessary for packing the MF fruit pieces, even if they are stacked.
- the length L is, for example, chosen to be practically twice that required for fruit pieces.
- the bag is partially exposed and then sealed.
- the bag has a reduced volume 100R with respect to its maximum volume 100M shown in broken lines. Its end January 12 is heat-sealed with a heat-sealing device 400.
- the sealed bag 100R is subjected to heat preservation treatment in the microwave oven 410 schematized by two lines.
- the fruit pieces MF are grouped on a fraction L0 of the length L of the bag, for example half, and this portion 100B of the bag is sealed with respect to the remaining part 100C by an intermediate weld 1 13 with a heat sealing device 420 between the ends 101, 1 12 of the initial bag.
- the bag is cut next to or in the middle of the weld 113 so as to remove the part 100E which has become useless.
- This grouping of the fruit pieces in the bag portion 100C, the intermediate seam 103 and the cup of the bag portion 100E in excess, are operations performed without opening the chilled bag, after the microwave oven treatment 410.
- the brief heat treatment applied to the fruits for their conditioning is a minimum temperature or a maximum temperature.
- a minimum temperature which varies according to the initial microbial load.
- the requirements will be stricter than for a melon.
- a pineapple will tolerate a temperature of 100 ° C, while the temperature of the melon must not exceed 70 ° C.
- the meaning resulting from brief heating is more or less strong.
- a mango will not undergo taste alteration up to 90 ° C, while a kiwi should not exceed a temperature of 60 ° C.
- the pieces of fruit should be treated in a range of temperature variable according to the fruits.
- the treatment will for example be of a duration of 5 seconds for a temperature between 80 ° and 100 ° C; in the case of a piece of mango, the treatment will last for 5 seconds and at a temperature between 70 ° and 90 ° C.
- the duration of treatment will be 30 seconds and the temperature between 50 ° and 70 ° C.
- the control carried out according to the process of the invention is a measurement of the surface temperature of each piece. This measurement is done as indicated through the transparent packaging and is made immediately after the treatment in the oven.
- the fruit pieces are aligned or in the form of a single layer in the package during treatment in the oven. After the treatment and the temperature detection, when the volume of the bag is reduced, the fruits can be more grouped and if necessary overlap.
