antimicrobial activity of plant extracts in traditional medicine on bacteria and fungi has been identified. medicinal plants have been used since ancient times as a food coloring and flavoring agents. also, plant extracts have been used for the prevention of diseases caused by food borne pathogens. with the use of active packaging that can interact with the environment and product, increased sh...

Bet-hedging theory addresses how individuals should optimize fitness in varying and unpredictable environments by sacrificing mean fitness to decrease variation in fitness. So far, three main bet-hedging strategies have been described: conservative bet-hedging (play it safe), diversified bet-hedging (don't put all eggs in one basket) and adaptive coin flipping (choose a strategy at random from ...

Population dynamics of Meloidogyne chitwoodi were studied for 2 years in a commercial potato field and microplots. Annual second-stage juvenile (J2) densities peaked at harvest in mid-fall, declined through the winter, and were lowest in early summer. In the field and in one microplot study, population increase displayed trimodal patterns during the 1984 and 1985 seasons. Overwintering nematode...

BACKGROUND The objective of the current study was to measure dietary diversity in South Africans aged 16 years and older from all population groups as a proxy of food security. METHODS A cross-sectional study representative of adults from all specified ages, provinces, geographic localities, and socio-economic strata in South Africa was used (n=3287). Trained interviewers visited participants...

This paper presents a model-based approach for competitive analysis of manufacturing plants in the U. S. food processing industry. As part of this approach, plant competitiveness is measured using Operational Competitiveness Ratings Analysis (OCRA) -a new non-parametric method of computing relative inefficiency. Drivers of competitiveness are identified in terms of policies related to plant str...

alternatives to meat are a growing market segment. The European LikeMeat project investigated consumers’ motivation for shifting their diets towards meat alternatives and developed a meat alternative product that resembles the fibrous structure, bite and juicy mouth-feel of meat. In a high moisture cooking extrusion process, plant proteins are converted to a base product that has a meat-like st...

Natural food preservation method refers to application of naturally produced antimicrobial compounds that are obtained from plants, animals and microbes to prevent food spoilages microorganism, proliferation and growth of food borne pathogens in food and foods products. Now it is the time of growing interest of many researchers with the application of these natural antimicrobial compounds as sa...

Forget about farm-to-fork when it comes to genetically modified (GM) crops. Think farm-to-pharmacy, or farmto-factory. Produced through plant molecular farming (PMF), this new set of transgenic crops is being grown not for food, but to produce medicines and industrial products. For example, potatoes have been modified to produce a vaccine against the Norwalk virus, research that is currently in...

introduction: active packaging is one of the innovations in food packaging industry that would be a respons to the changing needs of consumers and markets. in this technique, materials such as adsorbents oxygen, moisture, carbon dioxide, ethylene and carbon dioxide-releasing flavor compounds, antimicrobials, antioxidants and various aromatic compounds are used. in the last decade, great attenti...
