Shelf life of bottled natural fruit juice (BNFJ) provides relevant information on quality and authenticity for consumer protection. However, existing techniques for monitoring the shelf life of BNFJ are destructive and time-consuming. We report on using laser-induced autofluorescence (LIAF) spectroscopic technique in combination with multivariate analysis for shelf life monitoring of BNFJ. The LIAF spectra data were acquired for nine1 continuous days on three batches of BNFJ samples purchased from a certified retailer. Deconvolution of the LIAF spectra revealed underlying peaks representing constituents of the BNFJ. Principal component analysis (PCA) was able to monitor the trend in the changes of the BNFJ as it aged. Partial least square regression (PLSR) predicted the exact day from the production of the BNFJ accurately at 96.6 % and 98.8 % in the training and testing sets, respectively. We, therefore, propose the LIAF combined with multivariate analysis as a potential tool for nondestructive, rapid, and relatively inexpensive monitoring of the shelf life of BNFJ.

Bayer announced a partnership with French company M2i Group to supply fruit and vegetable growers around the world with pheromone-based biological crop protection products. Through the agreement, Bayer will become the exclusive distributor of select M2i products targeting lepidoptera pests in crops that include stone and pome fruits, tomatoes, and grapes.

M2i Group is the leader in pheromone production in Europe and has expertise in developing, formulating, and manufacturing complex molecules. Bayer will integrate M2i’s pheromone products, including M2i’s innovative press application technology, into a complementary system of digitally enabled solutions that include pest monitoring tools to advise growers on pest pressures and application timelines, and other synthetic and biological products tailored to grower needs.

“Tailored solutions that meet growers’ demands for safe and effective products with low or no residue are an important part of Bayer’s biological portfolio,” said Jens Hartmann, Regional Head for Europe, Middle East, and Africa (EMEA). “Bringing together M2i’s pheromone products with digital monitoring applications and Bayer’s existing biological portfolio will enable growers to apply the right product at the right time within a holistic approach that benefits their operations.”

M2i’s expertise in pheromone crop protection has allowed the company to utilise biomimicry to develop innovative methods that fight pests by attracting and trapping them or interrupting mating behaviors. These integrated pest management products ensure that pest populations are maintained at manageable levels.

“M2i Group is excited to work with Bayer and to bring our sustainable crop protection products to more growers around the world,” said Phillippe Guerret, CEO of M2i. “Pheromones present an efficient and economical method of crop protection, as they are selective, non-toxic, and naturally avoid the development of resistance. M2i’s patented technology leverages innovative application devices, and reliable linear release to bring the potential of pheromones to fields across the world.”

Bayer launched Vynyty Citrus®, its latest biological and pheromone-based crop protection product in 2021. Vynyty Citrus® is the first such product on the market that is formulated with pheromones and natural pyrethrum to control pests in citrus fruits. M2i’s products will continue to build on Bayer’s pheromone-based biologicals product line.

Leading branded soft drinks business, Britvic is joining forces with University of Cambridge-backed tech company Xampla in a GBP 1 million packaging innovation partnership.

After 15 years of Cambridge research, Xampla has developed the world’s first plant protein material for commercial use. This revolutionary material uses pea protein to make microscopic capsules that protect vitamins within liquid, stopping them from being broken down by sunlight.

Xampla’s work has seen the company secure GBP 1 million in funding from the UK Government’s innovation agency, Innovate UK, to scale up the technology and material processing.

The innovation is critical to delivering drinks fortified with vitamins in clear plastic bottles. Clear plastic bottles are considered a positive by consumers, with Britvic’s research showing that people are 40 % more likely to recycle clear bottles over coloured ones. However, the downside of clear bottles is that they let more UV rays in, losing the necessary protection for vitamin D.

Simon Hombersley, CEO of Xampla, said: “We are delighted to be partnering with Britvic to deliver innovation that will revolutionise the drinks industry and it is extremely exciting to see what our material can do at scale. Xampla works with businesses to help solve their biggest problems while also enabling customers to meet their sustainability goals.

“Britvic has a proud history of fortifying its products with vitamins and seeking sustainability in its packaging. Our partnership is about helping to do both even more effectively. We can’t wait to get started.”

Last year, major Britvic brands Fruit Shoot and 7UP made the shift to clear bottles to drive up recycling rates and Britvic has started to add vitamins B, C and D to Robinsons Fruit & Barley.

Meanwhile, leading Irish squash brand MiWadi 0 % Sugar contains vitamins B, D and zinc and children’s favourite Fruit Shoot has been fortified with multivitamins since 2016. Added vitamins C and D help support the immune system and the growth of strong bones, while B vitamins contribute to energy release.

Sarah Webster, Director of Sustainable Business at Britvic, said: “Our work with Xampla supports our Healthier People, Healthier Planet strategy.

“By agreeing this GBP 1 million partnership with each other, we have shown the power of collaboration between established players and cutting-edge innovators to deliver Healthier People and Healthier Planet.

“Xampla technology has the makings of a ‘win-win’, enabling delivery of greater nutritional value in the drinks people love, while ensuring that more products can come to market in clear, recyclable bottles.”

Britvic has a long history of fortifying drinks with vitamins. The FTSE 250 company started life in 1845 as The British Vitamin Product Company, with a mission to provide customers with an affordable source of nutrition. The company is committed to a programme to reduce unnecessary plastic and is working with Xampla through an Innovate UK-backed grant to develop new formats for delivery of soft drinks and nutrients within drinks.

News of the Britvic partnership follows a successful Xampla world first product launch with meal kit manufacturer Gousto last year, where Xampla created an edible film to be used as wrapping for stock cubes. The trial kits – for making an Indian Spiced Carrot & Lentil soup recipe – sold out within one hour of going on sale.
