The present article responds to the food engineering community's growing interest in an emerging and lauded approach to food preservation, popularised by its developers as ''. A strong campaign in the scientific literature and mass media has recently promoted this technique as a universal replacement for traditional food freezing and the frozen supply chain by highlighting a number of alleged advantages of ''. Some of these claims therefore require a more neutral and critical assessment against the background of the today's state of the art in food freezing technologies.

Article Synopsis
  • - The study explored how different sweeteners (like Stevia and Neotame) in biscuits affect appetite and hormone responses compared to regular sugar (sucrose) in adults with overweight or obesity.
  • - Participants consumed biscuits with varying sweeteners over two-week periods; results showed that all formulations similarly reduced appetite, but Neotame and Stevia led to lower insulin levels after eating compared to sugar.
  • - Overall, replacing sugar with these sweeteners had no significant impact on appetite or hormonal responses over time, although they did help in lowering post-meal insulin and glucose levels.

Malt flour represents a potential clean label bread improver, but a high enzymatic activity can lead to some bread defects. Thus, this study was focused on applying different thermal treatments (10 and 40 min; 70-90 °C) to green barley malt in order to promote a partial enzyme inactivation. The addition of 1.

In most soft wheat products such as cakes, baking powder (BP) plays an important role in achieving the desired product volume through batter aeration by the release of CO during baking. However, the optimization of a blend of constituents in BP is minimally documented, especially the selection of acids, which is often supported by the suppliers based on their experience. The objective of this study was to evaluate the impact of two sodium acid pyrophosphate leavening acids (SAPP10 and SAPP40) at different levels in BP on final pound cake properties.

  • The study examined how replacing sucrose with maltitol and sorbitol affected dough and crumb textures in biscuits.
  • Researchers used various analysis methods (like X-ray diffraction and calorimetry) to explore how starch behaved at different moisture levels in the dough.
  • Findings showed that sorbitol dissolved completely while sucrose and maltitol left behind crystals, impacting the temperature and degree of starch gelatinization based on how the sweeteners interacted with water.

The increased awareness of consumers regarding unfamiliar labels speeded up the ongoing clean label trend. As baking products are widely consumed worldwide, the reduction of non-natural baking aids and improvers is of great interest for consumer's health but also representing a big challenge for food industries. Thus, this paper aims at describing new techno-functional clean label ingredients for baked products and their production processes conditions.

Article Synopsis
  • * The study focused on replacing sugar with two polyols, maltitol and sorbitol, in short-dough biscuits, analyzing their physical, visual, and taste characteristics.
  • * Findings showed that although the reformulated biscuits had improved structural properties and appealing colors, they were generally less favored in taste, with maltitol being a more acceptable substitute compared to sorbitol.

Starch is a versatile and a widely used ingredient, with applications in many industries including adhesive and binding, paper making, corrugating, construction, paints and coatings, chemical, pharmaceutical, textiles, oilfield, food and feed. However, native starches present limited applications, which impairs their industrial use. Consequently, starch is commonly modified to achieve desired properties.

The aim of this research is to contribute to a better understanding the destructuration of three native starches and a wheat flour in mixtures of water and choline chloride. Model systems have thus been defined to allow a better approach to hydrothermic transformations related to the interactions between choline chloride and starch. We have observed that choline chloride has an impact on the gelatinization of starch which corresponds to the stabilizing salts phenomenon.

The aim of the present study was to evaluate Raman spectroscopy in determining changes that occur in the structure of gluten proteins induced during bread dough mixing. Raman spectra were measured directly within the dough. Three particular phases of mixing were studied: under-mixing, optimum mixing and over-mixing.

This paper presents a study on the effect of storage conditions on wheat flour quality for 30 months. Such study may be of interest for research projects conducted over long periods. Wheat flours were stored in two types of packaging (permeable paper bags and watertight containers) and at two temperatures (ambient temperature and a cold storage room).

The futuristic technology of three-dimensional (3D) printing is an additive manufacturing that allows obtaining creative and personalized food products. In this context, the study of food formulations (named as "inks") to be processed through 3D printing is necessary. This work investigated the use of dry heating treatment (DHT), a simple and safe method, to improve the wheat starch properties aiming to produce hydrogels to be used as "inks" for 3D printing.

This work evaluated for the first time the effect of dual modification of cassava starch by using ozone (O) and dry heating treatment (DHT). The dual modification was capable to promote fissures on the surface of the starch granule (DHT + O), affected the starch amorphous domains, presented greater degree of starch oxidation (DHT + O) and different profiles of starch molecular size distribution. These modifications resulted in starches with different properties.

3D printing is a technology capable of presenting creative, unique and intricate items in an attractive format, with specific compositions. However, novel ingredients must be developed to satisfy this new technological requirement. This work proposes dry heating treatment (DHT), a simple physical technique, as a method for modifying cassava starch, with particular focus on its use for 3D printing.

This study considered the effect of low energy microwave assisted freezing (MAF) on freezing time and quality attributes (microstructure, texture, drip loss and colour) of apple and potato. MAF of apples and potatoes was performed by applying constant microwave (MW) power (167 W/kg) and pulsed MW power (500 and 667 W/kg with 10 s pulse width and 20 s pulse interval resulting in an average power of 167 and 222 W/kg) during the freezing process. The temperature profile was monitored during the freezing process, and the microstructure was examined using X-ray micro-tomography and cryo-SEM.

The fragility of biscuits yields checking (cracks) and eventually breakage, which originated mainly from heterogeneity in water distribution in the thickness dimension (surface vs centre) and also to the plan dimension (edge vs centre) of the product. The objective of the BRICE project is to study the impact of the distribution of water on the occurrence of checking and breakage (C&B) in biscuits, considering a round and thick biscuit and a rectangular and thinner biscuit presenting piercing points. C&B counting was performed over 15 days of storage (the time needed to reach stability).

Freezing is an efficient and widely used method of food preservation. However, it can also cause irreversible damages at cellular level which in turn degrade the overall quality of the frozen food products. Therefore, qualitative and quantitative methods and technologies that will be able to evaluate with accuracy the freeze damage are of great importance.
