Research

Bioactives: Key Focus Area

Integrated research in metabolomics, genomics, biochemistry, phytochemistry, pharmacogenomics, breeding and epigenetics are aimed at development and promotion of fruits, vegetables and other edible plant material with enhanced health benefits, and introduction of new or underappreciated crops and products from various sites throughout the globe, allowing consumers to make proactive, responsible dietary choices that benefit their own, and their families’ health.

VacCAP: Leveraging genetic and genomic resources to enable development of blueberry and cranberry cultivars with improved fruit quality attributes

The Vaccinium (blueberry and cranberry) industries have identified development of cultivars with improved fruit quality (firmer texture, good flavor, appealing appearance) and longer shelf life as top research priorities critical to future success. This project aims to deliver empirical data to breeders and enhanced tools to select for high fruit quality.

Pulse-fruit aggregate ingredients with enhanced taste, functionality and health attributes for diversified food applications

In this 3 year plan of work, we A) Develop a scalable and environmentally-friendly processing route for high quality pulse-fruit aggregate ingredients, and demonstrate their health-relevant composition, physicochemical and functional attributes and digestibility in vitro; B) Scale-up the production of one prioritized pulse-fruit aggregate ingredient to formulate mainstream pulse shelf-stable ready-to-eat products in a convenient, appealing format and C) Evaluate the pulse-fruit food product (delivery vehicle for phytoactive content and fiber) in a human clinical trial for management of MetSyn and obesity risk factors.

Food Matrix Functionality

Proteins of plant (chickpea, rice, pea) or animal (whey) origin are complexed with plant polyphenols in a green chemistry approach to create meso-scale chimeric particles that can dramatically enhance the physical structure functionality of food products. The complexation process is used to steer protein aggregation to produce functionally inert particles (ingredients), resulting in improved foaming characteristics and creep recovery. These particles, when incorporated into a food matrix (e.g. protein bars), effectively extend the availability/digestibility of health-protective polyphenols and proteins in foods as well as the shelf life and optimal texture.

Retraining the Immune System: Mitigating Allergic Responses using Hypoallergenic Peanut Protein-Polyphenol Aggregates

Closing the Gap in Delivery of Fruit & Vegetable Benefits

Our overall goal is to develop strategies that close the gap between present consumption levels and the health benefits of fruits and vegetables through improvement of nutritional quality and delivery. The Central Hypothesis is that expansion of strategies to include identification of genetic factors that influence bioavailability of micronutrients and phytoactives can be synergized with emerging food production technologies to deliver more nutrition and health benefits within current consumer lifestyle and dietary habits. Translation of these strategies can bridge the gap between production and consumption through generation of more effective consumer produce and products.

Functional Genomics and Functional Phenotyping of Blueberry Fruits

The main goals of this project are: i) to generate blueberry genomic resources to facilitate completion of the blueberry genome assembly and to construct genetic maps to assist molecular breeding; ii) to use systems level approaches to study blueberry fruit development; iii) to study biofunctions of blueberry phytochemical profiles using a comprehensive suite of phytochemical analyses and in vitro assays; and iv) to develop and distribute news releases and educational materials, including community outreach and educational programs with local schools, to advocate wider public understanding of how research conducted at PHHI impacts human health.

Seaweed

Six species of coastal Alaskan seaweed (Alaria marginata, Fucus distichus, Pyropia fallax, Saccharina groenlandica, Saccharina latissima, and Ulva lactuca) were evaluated in multiple in vitro assay systems for their potential to attenuate diabetes and obesity, and the underlying phytochemistry that might play a role in the observed bioactivity was investigated.

Malaria

Working with the Gates Foundation’s Medicines for Malaria Venture, the Lilalab worked in conjunction with Rutgers University as well as the University of Cape Town in order to uncover new candidates in the fight against malaria.

AK/ND Education

In this project, awarded from the USDA Higher Education Challenge (HEC), the Lilalab collaborates with education experts at North Carolina State University, Rutgers University, the University of Alaska Anchorage, the University of Alaska Fairbanks, and United Tribes Technical College in North Dakota to develop a lab/lecture curriculum based upon hands-on investigation and bioassays of indigenous/endemic plants of historic importance to the Traditional Ecological Knowledge.

Zambia

The Bill & Melinda Gates Foundation-funded Nutrasorb-Zambia Project developed and validated an innovative, portable and highly stable protein-rich food source (fortified with bioactive fruit constituents and comprised of locally-available produce) to enable year-round healthy growth and development of undernourished mothers and children in Zambia and to establish the scientific foundations, network, and infrastructure to support subsequent technology transfer to facilitate sustainable regional implementation of the program in partnership with universities, entrepreneurs and government in Zambia.
