Impact of cyclic and continuous dry heat modification on the structural, thermal, technological, and in vitro digestibility properties of potato starch (Solanum tuberosum L.): A comparative study.

Dry heat treatment (DHT) has been demonstrated as a viable method for starch modification, offering benefits due to its environmentally friendly process and low operational costs. This research modified potato starch using different DHT conditions (continuous-CDHT and cyclic-RDHT), with durations ranging from 3 to 15 h and 1 to 5 cycles, at 120 °C. The study investigated and compared the structural, thermal, pasting, and morphological properties of the treated samples to those of untreated potato starch, including in vitro digestibility post-modification.

Pre milling debranning of wheat with a commercial system to improve flour quality.

In the present study wheat () cultivars were treated with industrial debranning step pre-milling both in a laboratory and a commercial mill to evaluate the benefits of this technology. Different levels of removal of wheat external layers were made (0 to 6%) and the results showed improved color of the flours (0.22 L* value units).

Production of Collagens and Protein Hydrolysates with Antimicrobial and Antioxidant Activity from Sheep Slaughter By-Products.

This work aimed to produce collagens and hydrolysates with antimicrobial and antioxidant activity from sheep slaughter by-products. The by-products (sheep and lamb) were treated and extracted. The collagens were hydrolyzed with the enzyme Alcalase.

Extraction and characterization of collagen from sheep slaughter by-products.

There is a growing search for alternative raw materials to obtain collagen and hydrolysates and processes that do not threaten the environment or human health. Thus, sheep slaughter residue, which doesn't yet have an adequate and sustainable destination, is an excellent source of study. The objective of this study was to investigate the technological properties of collagen extracted from sheep slaughter by-products.

Cassava starch films reinforced with lignocellulose nanofibers from cassava bagasse.

Cassava bagasse, a high-fiber coproduct of cassava starch processing, was used to produce lignocellulose nanofibers (LCNF) to apply as reinforcement in cassava starch films. LCNF-reinforced cast starch films were evaluated for changes in structural, thermal and mechanical properties and compared with control films reinforced with commercial grade nanoclay (Nclay). Five different types of cassava starch cast-films were produced: no-reinforcement control, two LCNF-reinforced, and two Nclay-reinforced, each at 0.

Gluten-free baked foods with extended shelf-life.

The objective of this study was to develop a formulation that can retard staling/retrogradation of cheese breads without compromising their texture and expansion properties. During baking the dough expands and becomes soft, with lower density. Binary mixtures of cassava starch (Native + Oxidized) and with guar gum (Oxidized + Guar Gum) as well as a ternary mixture (Native + Oxidized + Guar Gum) were prepared.

Influence of Extrusion Cooking on In Vitro Digestibility, Physical and Sensory Properties of Brazilian Pine Seeds Flour (Araucaria Angustifolia).

Brazilian pine seeds (pinhão) are gluten-free products derived from Araucaria angustifolia. The commercialization of these seeds is essentially associated with a low level of industrialization. In this context, extrusion cooking is a potential alternative for preparing extrudates of pinhão as a food product, which can be easily digested and is ready for human consumption.

Ripened Semihard Cheese Covered with Lard and Dehydrated Rosemary (Rosmarinus officinalis L.) Leaves: Processing, Characterization, and Quality Traits.

This study aimed to establish a manufacturing protocol and to characterize semihard cheese covered with lard and rosemary during ripening. After the manufacturing protocol was defined, the cheeses were produced with pasteurized and raw milk from Holstein cows, with and without (control) coating, and then ripened for 60 d. During this period the physicochemical properties, color, proteolysis, texture profile, and sensory acceptance were performed.

Physicochemical properties of cassava starch oxidized by sodium hypochlorite.

In this work, cassava starch was modified by treatment with sodium hypochlorite (NaClO) at different concentrations (0.8, 2.0 and 5.

Optimisation of the extraction of phenolic compounds from apples using response surface methodology.

The extraction of phenolic compounds from apples was optimised using response surface methodology (RSM). A Box-Behnken design was conducted to analyse the effects of solvent concentration (methanol or acetone), temperature and time on the extraction of total phenolic content, total flavonoids and antioxidant capacity (FRAP and DPPH). Analysis of the individual phenolics was performed by HPLC in optimal extraction conditions.

Cassava starch as a stabilizer of soy-based beverages.

Soy-based beverages are presented as healthy food alternatives for human nutrition. Cassava (Manihot esculenta, Crantz) starch is relatively inexpensive, widely available in Brazil and is broadly used by the food industry due to its desired properties that result from pasting. The objective of this study was to develop soy-based beverages with good sensory quality using native cassava starch as a stabilizer and maintaining the nutritional value that makes this product a functional food.
