Improving chestnut physicochemical properties through fermentation - Development of chestnut Amazake.

The increased awareness of population regarding the impact of consumption habits is leading to interest in new, innovative, diversified and health promoting foods. In this work, two new amazake fermented products were developed with chestnut ( Mill.), using rice or chestnut koji as source of glycolytic enzymes.

The impact of COVID-19 on diet quality, food security and nutrition in low and middle income countries: A systematic review of the evidence.

Background & Aims: The current global pandemic of Coronavirus (COVID-19), and measures adopted to reduce its spread, threaten the nutritional status of populations in Low- and middle-income countries (LMICs). Documenting how the COVID-19 affects diets, nutrition and food security can help generating evidence-informed recommendations for mitigating interventions and policies.

Methods: We carried out a systematic literature review.

Improving nutritional quality of unripe tomato through fermentation by a consortium of yeast and lactic acid bacteria.

Background: Portugal is one of the main producers of industrial tomato and tomato paste, an important intermediate ingredient used in many added-value foods. The tomato processing industry rigorously selects the fruits by colour during mechanical harvest, picking only completely ripe fruits to produce high quality tomato paste. The latest available data shows that about 1.

Industrial sustainability of microbial keratinases: production and potential applications.

Keratinases are proteolytic enzymes with a particular ability to cleave peptide bonds in keratin, and in other proteins. Due to their broad-spectrum of activity, keratinases are considered viable substitutes for chemical and thermal treatments of protein-rich industrial by-products. Among these protein residues, special attention has been given to keratinous materials (feathers, hair, horns, etc.

Development and physicochemical characterization of a new grass pea (Lathyrus sativus L.) miso.

Background: Western consumers interest in Eastern fermented foods has been growing, due to their nutritional and healthy properties. In this study, new sweet misos and salty misos were produced using grass pea (Lathyrus sativus L.) - traditional Portuguese legume from local producers - to promote its consumption and preservation.
