Full textMany industries are interested in the High Pressures technology, especially the food industry. High pressure thawing, which makes profitable the decrease of the temperature of the freezing point with the pressure (-22°C at 220 MPa), is one of the most innovative applications. Thawing is then faster than conventional methods and, as it is carried out at low temperature, it avoids microbial contamination. The main objective of this work consists in modelling the high pressure thawing process. The major phenomena considered are the internal transfers with phase change and the natural convection between the surface of the food and the heating medium. We firstly studied the variation of the food properties with the temperature and the pressure. The simulation was carried out at atmospheric pressure in order to validate the model developed using the CFD code CFX5. 5. The analysis of temperature and velocity fields in non stationary regime lead to some observations of the process. The predictions performed on an experimental set-up were in a good agreement with the experimental data. The influence of the pressure, heat of compression and modification of food and medium properties was then taken into account. Simulations were also validated from a thermal point of view on a pilot-scale vessel and the model was then used to study the effect of the pressure on thawing time. Lastly, a parametric study was performed in order to evaluate some modifications and to optimize the process at an industrial scale. The potential benefit of forced convection was clearly demonstrated and the study of the filling rate open the way to further works

Full textThe present work enters within the framework of the definition of a new process of thermomecanical treatment, of rice in view to improve some, to the weakest cost, nutritionnal and organoleptic characteristics. To the plan of the convenience of the consumer, the main objective resides in an aspect that takes increasingly the importance : the reduction of the time of cooking. A new unit operation has thus Summer applied : the Controlled Instantaneous Decompression (DIC), realized to reduced pressures. This process consists in make undergo to the product a processing of high temperature and short time (HTST) followed by a decompression to the void. The texturation is provoked by an auto vaporization of the water of the product implying its possible expansion. Two distinct processings by DIC have been envisaged, analyzed then optimized : precooked of whitened rice and parboiling by microexpansion of raw rice (Indica and Basmati), the first allows to end to product of a short time of cooking (3 to 4 minutes) while the time of cooking of the parboiled rice is 12 minutes under its complete form and 8 minutes after abrasion. Furthermore, we have been interested in the characterization of the finished product in view to estimate its quality. A comparative method study of analysis (MEB, Ray X, DSC and spectrophotometry) of the phenomenon of gelatinization, has allowed us to quantify this phenomenon. The rate of gelatinization can reach 90%. On the other hand, the measure of the texture of the product, is in first determined by sensory analysis. Instrumental methods have thereafter been realized by two machines: the texturometer and the viscoelastograph. A correlation between the various sensorial measure and instrumental has been obtained : the texturometer can better translate sensory measures defining the state of cooking of rice with a coefficient of correlation of 98%. The characterization of the finished product has seeked to the level vitaminic all particularly the content in vitamin E, realized by analysis Chromatographic. Parboiling by DIC of raw rice induces a relatively low reduction in vitamin E. To the light of the totality of these results, is undertaken an approach to the extrapolation of industrial scale. Two types of reactors have been proposed. The first is Static type capable to process 5 tons/h with a total cost of 4 cents by kg of rice. The second type is (dynamics) whose main difference with the static reactor resides in the ejection of the product during the decompression. A dynamic reactor has been able thus to be proposed to the industrial scale

Full textCrustacean processing has an economic importance in Quebec. This industry generates substantial amounts of solid and liquid wastes in the environment, which causes pollution. However, these wastes constitute a potential source of valuable molecules. Very few works are dedicated to the crustacean effluents’ valorization comparatively to the solid wastes. Cooking waters, more specifically, could contain high-value biomolecules like pigments, peptides, as well as flavor compounds. This work is about the valorization of snow crab and lobster cooking effluents, aiming to develop bioingredients for food applications. To do this, a reverse osmosis process has been optimized and applied to the cooking waters. This was followed by a freeze-drying step. The chemical composition of the generated fractions has been assessed. Retentates are mainly composed of proteins (38.8-59.2 %) and minerals (35.8-45.7 %). Aroma and taste compounds in the freeze-dried retentates have been identified and quantified. The retentates contain desirable molecules. Moreover, their safety was verified. Functional properties (solubility, water-holding capacity) and antioxidant capacity have been assessed in snow crab freeze-dried retentates (137.6 μmol Trolox equivalent/g). The results obtained show that snow crab and lobster cooking waters can be valorized as natural aromas in the food industry.

Full textThere is an increasing demand for beverages enriched with proteins and dietary fibers but this development is still a technological challenge due to protein instability in acidic condition after heat treatment. The objective of this work was to study the effect of homogenization before/after pasteurization on the stability of proteins and proteins/pectin complexes in presence of β-glucan in juice model during the storage at 4°C. The stability was evaluated by visual observation (phase separation, precipitation) and distribution of proteins was determined at storage time of 1, 7, 14, 21 and 28 days. The size, the charge of the particles and the viscosity of the solutions were measured in days 1 and 28. A homogenization step performed after pasteurization increased the proteins’ stability by significant decrease in particle size. However, the homogenization performed before pasteurization had no effect. The addition of low concentrations of pectin did not stabilize the proteins after pasteurization. The complexes obtained had a low charge and a large size that homogenization could not reduce. The addition of β-glucan promoted the proportion of precipitate for the beverage with proteins alone and did not affect proteins’ stability in the presence of pectin. However, the insoluble proteins in the precipitate phases are resuspended easily by some tube inversions. This work demonstrated that homogenization is a simple treatment that could help stabilize fortified beverages but it requires adaptation to usual procedure.

Full textLes larves de mouches soldats noires représentent un ingrédient alternatif prometteur pour le bétail, mais les étapes de transformation peuvent affecter leur qualité. Les périodes de vidange gastrique utilisées pour évacuer les excréments du tractus digestif afin de réduire sa charge microbienne, et les méthodes d’abattage sont variables et peu documentées. Ce projet vise à optimiser la vidange gastrique et l’abattage des larves pour en maximiser la qualité. En effet, un jeûne prolongé et une méthode d’abattage inadéquate pourraient altérer la composition et la microbiologie du produit. Le temps d’évacuation du tractus digestif des larves alimentées de Gainesville a été déterminé en suivant l’excrétion des fèces aux douze heures. Puis, l’impact du temps de jeûne sur la composition et la contamination ont été mesurés quotidiennement pendant quatre jours. Également, les effets de dix méthodes d’abattage sur la composition, la microbiologie et la coloration ont été comparés : ébouillantage (40 s), dessiccation (60 °C, 30 min), congélation (-20 °C et -40 °C, 1 h; azote liquide, 40 s), hautes pressions hydrostatiques (3 min, 600 MPa), broyage (2 min) et asphyxie (CO2 et conditionnement sous vide, 120 h; N2, 144 h). Bien que le temps d’évacuation du tractus digestif médian fût de 72 h, un jeûne de 96 h n’a pas permis de réduire la contamination. Certaines méthodes d’abattage ont affecté le pH, la stabilité de la couleur ainsi que la charge microbienne. De plus, ébouillantage, asphyxie et dessiccation ont affecté la composition proximale et l’oxydation des lipides. Malgré l’incapacité de la vidange gastrique à réduire la contamination des larves, l’ébouillantage apparait comme la méthode la plus appropriée en réduisant la charge microbienne et l’humidité tout en minimisant l’oxydation des lipides. Nous proposons donc un protocole pour abattre les larves répondant aux exigences réglementaires canadiennes en matière de transformation des insectes.
Black soldier fly (BSF) larvae represents a promising alternative ingredient for animal feed, but post-production processing can affect their quality. Feed withdrawal periods (FWP) used to evacuate fecal matter from the gastrointestinal tract, reducing the microbial load (ML), and killing methods are variable and poorly documented. This project aims to optimize the FWP and killing methods of BSF larvae to maximize product quality. Indeed, a prolonged FWP and an inappropriate killing method could alter larvae composition and ML. The gastrointestinal evacuation time (GET) of BSF larvae fed on coloured Gainesville diet was determined by following frass excretion every 12 h for 108 h. Then, FWP impact on the proximate composition and ML was measured daily over four days. Finally, the effects on the chemical composition, ML and colour of 10 killing methods were compared, i.e., blanching (B = 40 s), desiccation (D = 60 °C, 30 min), freezing (F20 = − 20 °C, 1 h; F40 = − 40 °C, 1 h; N = liquid nitrogen, 40 s), high hydrostatic pressure (HHP = 3 min, 600 MPa), grinding (G = 2 min) and asphyxiation (CO2 = 120 h; N2 = 144 h ; vacuum conditioning, V = 120 h). Although, the median GET was 72 h, a 96 h FWP did not reduce larvae ML. Certain killing methods affected the pH (B, asphyxiation), total moisture (B, asphyxiation and D), ash (B), lipid content (asphyxiation) and lipid oxidation (B, asphyxiation and D), as well as the colour stability during freeze-drying. FWP were ineffective in reducing the ML. Blanching appeared as the most appropriate method since it minimizes lipid oxidation, reduces ML and total moisture (78.1 ± 1.0%). Our studies propose a standardize protocol to kill BSF that meet the Canadian regulatory requirements of the insect production and processing industry.

Full textLes larves de mouches soldat noires (Hermetiaillucens, HI) sont une source alternative de protéines et d’énergie pour l’alimentation du bétail. De nombreux aspects liés à l’optimisation des procédés de transformation pour assurer l’innocuité, la conservation et la qualité nutritionnelle de ce nouvel ingrédient sont cependant encore peu connus. Cette étude vise à optimiser les techniques de conditionnement et de séchage des larves pour réduire efficacement leur contenu en eau et leur charge microbienne, afin d’établir les paramètres de transformation en une farine de larves respectant les exigences de l’Agence canadienne d’inspection des aliments, tout en minimisant les impacts négatifs sur la qualité nutritionnelle. Après 10 jours d’alimentation sur une diète de contrôle Gainesville à 27°C et 70% d’humidité, les larves de mouches HI ont été récoltées par immersion, rincées à l’eau stérile, emballées sous vide pour être congelées, et ainsi euthanasiées, à -40°C (n=3 productions). Après décongélation, des aliquotes de 30g/traitement (n= 3) ont été prétraitées, ou non, par blanchiment (100°C/40s), ébouillantage (100°C/2, 4, 6 et 8min) ou perforées mécaniquement avant d’être séchées à air chaud (60°C) ou lyophilisées (40°C) jusqu’à une activité de l’eau finale ≤ 0,3 pour la farine de larve. La qualité microbiologique des larves a été évaluée par dénombrement incluant les aérobes mésophiles totaux (AMT), Pseudomonasspp., Listeriaspp., les bactéries lactiques présomptives, les entérobactéries et les coliformes. L’impact des techniques de séchage sur les propriétés physicochimiques et nutritionnelles a été déterminé par la couleur (L*, a*, b*, ∆E), le pH des larves avant et après transformation, l’oxydation des lipides (TBARS, Xylénol Orange) ainsi quela teneur en lipides et en protéines. Nos analyses ont montré que la contamination initiale des larves en AMT (9 log ufc/g de larves fraîches sur base sèche) pouvait être réduite de l’ordre de 3 à 4 log ufc/g après prétraitement suivi d’un séchage à air chaud (60°C). L’ébouillantage pendant 4min à 100 °C suivi d’un séchage à l’air chaud à 60 °C pendant 6h se sont avérés être les paramètres à suivre pour un traitement optimal. La présence d’une cuticule recouverte de cires, qui réduit la déshydratation chez les larves vivantes, pourrait bien constituer un frein notable à l’évaporation lors du séchage.
Black soldier fly larvae (Hermetia illucens; BSFL) are an alternative source of protein and energy for livestock feeding. Many aspects related to process optimization to ensure the safety, conservation and nutritional quality of this new ingredient are still unknown. The presence of a wax-coated cuticle, to reduce drying of the larvae, constitutes a barrierto evaporation. The purpose of this study was to optimize larval conditioning and drying techniques to effectively reduce their water content and microbial load in order to establish the processing parameters into larval meal required by the Canadian Food Inspection Agency while minimizing negative impacts on nutritional quality. After 10 days of feeding on a Gainesville control diet at 27°Cand 70% moisture, BSFL were collected by sieving, they were rinsed with sterile water, packaged under vacuum, frozen at -40°C (n=3 replicates). After thawing, aliquots of 30g/treatment (n=3) were pretreated, or not, by blanching (100°C for 40s), boiling (100°C for 2, 4, 6 or 8 min) or mechanically perforated before being hot-air dried (60°C) or freeze-dried (40°C) until a final water activity ≤0.3 was obtained for the larval meal. The microbiological quality of the larvae was assessed by enumeration of total aerobic mesophilic (AMT), Pseudomonasspp., Listeriaspp., presumptive lactic acid bacteria, Enterobacteriaceae and coliforms. The impact of drying techniques on physicochemical and nutritional properties have been evaluated using colour (L*, a*, b*), larval pH before and after processing, lipid oxidation (xylenol orange, TBARS) and proximal composition including lipid and protein levels. The results demonstrate that the initial larvae contamination (9logCFU/g AMT of fresh larvae on dry basis) was reduced by 3 to 4 log CFU/gafter a pre-treatment followed by hot air drying (60°C); 4min boiling at 100°C followed by hot air drying at 60°C for 6h was found to be the optimal treatment parameter.
